It uses twin roller electrodes to preheat cylindrical thermoset molding preforms before compression or transfer molding. The heated compound flows more readily into the mold. Principal application areas include electronic encapsulation, electrical insulation and motor components.

Application areas include electrical switch and connector manufacturing, motor commutator molding, and automotive phenolic components such as brake pistons and electrical insulators. The relevant production route uses cylindrical preforms that are heated before compression or transfer molding.

Start with the shape of the molding charge. Roller electrodes suit regular cylindrical preforms that rotate during heating. Flat electrodes are generally better suited to powder, granules and irregular charges. If your current process heats loose powder in a cup, match the electrode arrangement to that material-handling method.

The tablets are prepared before heating, in an upstream cold-preforming operation or by the material supplier. The roller-electrode preheater heats and softens this measured charge. The downstream molding machine then shapes and cures the finished part.

In a typical roller-electrode process, an already formed cylindrical preform is placed in the roller heating area and rotates with the rollers. This differs from cup-loaded powder heating on flat electrodes. The loading arrangement can be matched to the actual preform.

Loading and removal of the heated preforms are manual. Lid opening and closing are automatic. Heating runs for the selected time, then stops as the lid opens automatically so the operator can transfer the charge to the molding machine.

Han Chang offers 3, 5, 7, 10 and 25 kW power options. Start by sending a product or preform photo, the compound name and details of the existing molding equipment. Available batch weights, preform dimensions and production targets help us recommend a suitable configuration and prepare a quotation.

It is a hydraulic press that uses a single main forming-cylinder configuration to mold suitable heat-curing compounds in a heated tool. Han Chang builds this press to order with a maximum forming force of 1200 tons. Its general molding sequence is charge loading, compression, mold-opening and closing venting, pressure-hold curing and part removal.

Choose it when the required molding force and the planned tool can be matched within its 1200-ton maximum and specified mold space. Han Chang configures the platen, daylight, stroke and molding motions around the job. A large mold needs enough mounting and removal space as well as enough force; the number of cavities is determined by the product and tool layout.

Required forming force depends on the compound’s molding pressure and the projected cavity area, including the total area and layout of a multi-cavity tool. Platen size follows the mold footprint and mounting needs. Daylight is the open space available for the tool and part handling, while stroke is the pressing travel. A deep basin and a long flat panel therefore need different space specifications.

Yes. Han Chang can configure it for compression-moldable SMC sheet charges or BMC/DMC bulk charges, including suitable glass-fiber-reinforced polyester and vinyl ester formulations. The tool is loaded, closed and pressed, opened and closed for venting, then held for curing. Compound flow, projected area and mold dimensions guide the equipment specification.

Material-specific builds can accommodate phenolic PF/Bakelite, melamine MF, urea-formaldehyde UF/UMC, epoxy, rubber and solid silicone suitable for hot compression curing. Application routes include industrial insulation parts, large trays, sanitary fittings and equipment-cover gaskets. Each material is paired with its appropriate heating, venting and curing setup.

Application directions include bathtubs, washbasins, long tabletops and large artistic products using suitable heat-curing molding compounds. SMC shower trays, sectional water tank panels, meter cabinet covers and industrial covers are further compression-molding development routes. The actual part and tooling requirements determine the appropriate single-cylinder build.

Han Chang offers the large single-cylinder press up to 1200 tons and the large twin-cylinder press from 1200 to 2000 tons. Both are built to order around the compound, mold and product. Start with the single-cylinder configuration when the required forming force and tool space fit the job; compare the twin-cylinder press for higher force requirements. Platen dimensions, daylight and removal clearance remain important alongside cylinder configuration.

The quotation depends on forming force, platen size, daylight, stroke, heating and the required molding motions. Tooling and handling provisions should be itemized so you can compare the same supply scope. Send Han Chang the product photo or drawing, dimensions and compound name; existing mold details and planned output help us develop the configuration and equipment quotation.

Han Chang can configure the press for SMC, BMC/DMC, glass-fiber-reinforced unsaturated polyester and vinyl ester composites, phenolic PF/Bakelite, melamine MF, urea-formaldehyde UF/UMC, epoxy molding compounds, rubber and solid silicone. The relevant formulations must be suitable for compression molding with heat curing, vulcanization or crosslinking. The selected compound and mold determine the equipment configuration.

SMC is sheet molding compound, while BMC/DMC refers to bulk or dough molding compound. FRP means fiber-reinforced plastic; GRP specifically means glass-fiber-reinforced plastic. For example, glass-fiber-reinforced polyester SMC combines polyester resin and glass fibers in sheet form and is also a GRP material. Han Chang configures the hot press for the compound’s flow and cure behavior, tool dimensions and required molding pressure.

Han Chang builds large twin-cylinder presses from 1200 to 2000 tons and large single-cylinder presses up to 1200 tons. Both are made to order. Start with the required forming force, then match mold space, daylight, stroke and molding motions. Within their shared 1200-ton range, tool mounting and part-removal requirements help guide the choice of single- or twin-cylinder configuration.

Tonnage is the available forming force; platen size is the working footprint for the tool. Required force depends primarily on the compound’s molding pressure and total projected cavity area, including all cavities and their layout in a multi-cavity tool. Select platen dimensions for the mold footprint and mounting space. Long tabletop tools need both a suitable footprint and forming force, while deep basin molds also need adequate daylight, stroke and part-removal clearance.

The typical sequence is charge loading, mold closing and pressing, mold-opening and closing venting, pressure-hold heat curing, then mold opening and part removal. Venting releases gases through the opening and closing of the mold before subsequent pressing. Its timing and the holding stage are configured for compound reaction, flow and part geometry.

Yes. The press can produce bathtubs, long tabletops, washbasins and large artistic objects using compounds and tools suited to hot compression molding. Further composite applications include SMC shower trays, building panels, water tank panels and industrial covers. Han Chang matches forming force, heating, venting and pressure-hold curing to the selected compound and mold, with opening and part-removal space configured for large or deep products.

Within the 1200–2000-ton build range, price depends on forming force, machine and platen dimensions, daylight, stroke, heating requirements and the complexity of the specified motions. Tooling and charge or part-handling arrangements also affect the total production investment. Compare manufacturer quotes against the same equipment requirements and clearly defined supply scope.

Yes. Send Han Chang a product photo or drawing, approximate dimensions and the compound name. Existing mold dimensions are helpful if available. We can discuss the forming force, platen space and molding configuration from those starting points, then provide an equipment quote once the specification and supply scope are defined.

Han Chang’s press removes excess flash from rubber and silicone films and molded parts. The operator loads the workpiece, a hydraulically driven cutting die moves downward to trim the required profile, and the operator removes the part manually. It is a practical choice for repeated post-molding trimming jobs.

Yes. The press is used for flash trimming on rubber and silicone films and finished molded products. Material thickness, hardness and elasticity help determine the cutting edge and workpiece support for each job.

Base the die on the finished outline and the flash that needs removing, together with the way the part is positioned and supported. A photo of the untrimmed part and a finished-part drawing make the trim locations, tooling space and cutting-force requirements easier to discuss.

Yes. An operator loads the workpiece and removes it after the hydraulic die-trimming action. Loading, cutting and inspection remain clear stages for arranging the workstation and daily handling.

Rubber and silicone films, flat sealing gaskets and pads are useful starting points, along with accessible perimeter flash on molded silicone feet and plugs. The purpose is to remove excess material at the required profile, reduce repeated hand trimming and make edge finishing more consistent.

Send Han Chang a photo showing the flash or a part drawing, the material and approximate dimensions. If a die already exists, include its footprint and height. Your current trimming method and expected workload help define the press requirements and quotation scope.

Han Chang’s Three-Cylinder Long-Platen Hot Press produces long seals, elongated rubber parts and panels from rubber, silicone, composites and phenolic (Bakelite) molding materials. Three lower hydraulic cylinders raise one shared long platen, supporting elongated tooling for hot compression and curing.

The three lower hydraulic cylinders work together to raise the same long platen. That platen carries the mold and applies upward closing force. Mold length, width, support requirements and total pressing force are considered together when selecting the configuration.

The operator loads material manually. Three lower hydraulic cylinders raise the platen to close the mold for heating, compression and pressure holding. Mold-opening and closing venting helps release gas during molding. After curing, the mold opens and the operator removes the part manually.

Yes. The 600, 900, 1200, 1500, 1800 and 2400 ton options each refer to the combined force of all three cylinders, not the force of one cylinder. Select total force using projected molding area, cavity count and required material molding pressure, together with suitable platen dimensions, daylight and stroke.

Platen dimensions, daylight and stroke can be customized. Price depends on total tonnage, working space and the hot-press configuration. Send Han Chang a product photo or drawing, material and approximate dimensions; an existing mold’s footprint and height help refine the configuration and quotation.

Han Chang’s Double-Cylinder Long-Platen Hot Press processes rubber, silicone, composites and phenolic (Bakelite) molding materials into strip seals, elongated rubber parts and industrial panels. Two lower hydraulic cylinders raise one shared long platen to support the mold during heated compression, pressure holding and mold venting.

The 400, 600, 800, 1000 and 1200-ton ratings are combined machine force for both cylinders, not force per cylinder. Choose total tonnage using projected molding area, cavity count and material molding pressure, then match the platen dimensions and opening space to the mold.

The operator loads the material by hand. Both lower cylinders then raise the shared platen to close the mold for heating and pressure holding. Opening and reclosing the mold for venting helps release gas during molding. After curing, the mold opens and the operator removes the part manually.

The double-cylinder design uses two lower hydraulic cylinders to raise one shared long platen; the three-cylinder design uses three. They follow the same hot-compression principle. This press has five combined-force options from 400 to 1200 tons, so compare total force, mold support and handling space when choosing a configuration.

Platen dimensions, daylight and stroke can be customized. Send Han Chang a part drawing or photo, material and approximate size; include the mold footprint and height if tooling is available. We can discuss the required total tonnage and working space, then prepare a quotation for the selected press configuration.

Han Chang’s Automatic Straightening Hydraulic Press corrects bending in steel and aluminum parts, long shafts, profiles and heat-treated workpieces. Supports carry the part while a pressing head applies localized hydraulic force; straightness is checked after unloading to assess the correction.

Start with shaft length, cross-section, material, hardness and the bend to be corrected. Support points and pressing-head position define the loaded section, while required force, ram stroke and target straightness guide the equipment arrangement.

Metal workpieces spring back when pressing force is removed. Unloaded straightness shows the correction that remains. Comparing that result with the force position and ram travel provides a useful basis for the next adjustment.

Use the material, hardness, heat-treatment condition, cross-section and initial bend to select force and ram travel. Match the support and pressing contact surfaces to the profile, then use unloaded straightness and springback observations to guide further adjustment.

The quotation depends on the part length and cross-section, required force, supports, pressing head, stroke and working space. Send Han Chang a part photo or drawing and the correction required to begin a configuration and price discussion; an existing straightness requirement helps refine the selection.

The Han Chang guarded hot compression molding press cannot make any movement unless the physical guard door is closed. Opening the door during operation stops the machine. This makes the press a strong choice for factories that require manual charging and part removal while prioritizing protection around the mold area.

The press supports rubber, silicone, phenolic Bakelite and thermoset composite molding materials. With suitable compounds and tooling, application directions include seals, gaskets, cushioning pads, grommets, molded handles and knobs, composite housings and covers. Part geometry and service performance depend on the compound, mold and molding conditions.

After manually loading the heated mold, the operator closes the guard door and starts the cycle. The machine closes, presses, vents by opening and reclosing the mold, holds under heat and pressure, and opens the mold. Once machine movement has stopped, the operator opens the guard and removes the part manually. The door stays closed during machine movement.

Platen size and daylight must accommodate the mold footprint, mold height and part-removal space. Pressing force is selected from the compound’s pressure requirements, projected cavity area and cavity count. The guard-door opening and operator position are included so mold fit and practical access work together.

Send a part photo, material description or available mold drawing to Han Chang. Dimensions, planned output and factory power details can follow as the discussion develops. We use the molding and handling requirements to recommend a suitable guarded press configuration and prepare a quotation.

Han Chang’s Rubber Tile Hydraulic Press forms rubber mixed with a binder into molded floor tiles. Feedstock can include recycled rubber and rubber from processed waste tires. Operators load the mix and remove the finished tiles manually. Park safety mats and factory floor mats are among the intended product applications.

Yes. Use rubber recovered from waste tires after upstream processing into suitable feedstock, then combine it with a binder for tile production. This machine presses the prepared mix into tiles; tire processing takes place before the forming stage.

The binder joins the rubber particles into a finished tile, while the mold and pressing operation establish its shape. Material quantity, mixing ratio, charge distribution and cure requirements help govern consistency from tile to tile.

Operators load the prepared mix into the mold and remove the finished tiles by hand. Plan mixing, loading, pressing, removal and finishing as connected operations when arranging workstations and labor.

Compare tile dimensions and construction, rubber feedstock, binder processing requirements, mold size and access for manual handling. These factors connect the press to the flooring you intend to sell, whether it is a factory workstation mat, playground tile or gym floor tile.

A meaningful quotation depends on the tile dimensions and construction, pressing requirements, mold accommodation and handling arrangement. Send Han Chang a product photo or drawing, feedstock details and planned production needs to begin. Existing mold dimensions are helpful where available.

Han Chang’s Hydraulic Deep Drawing Press forms stainless steel and steel sheet into pot bodies, basins and similar drawn vessels. The operator loads the blank, a hydraulic cylinder moves slowly downward to form the sheet with the tooling, and the operator removes the part manually.

A flat sheet blank is formed by tooling into a vessel with a base and sidewall. The blank geometry, material and required depth guide the drawing sequence. Han Chang’s press provides the slow downward hydraulic-cylinder action for this metal-forming operation.

Start with the pot body or basin profile, sheet grade and thickness. Opening diameter, wall depth and base radii help define the forming requirements, while the die dimensions and part-removal path define working-space needs. This links press selection to a specific vessel-forming task.

Ejection is an optional custom-specified feature. It can be arranged around the vessel shape, tooling and release direction to assist the part out of the die before the operator removes it by hand.

Grades differ in drawing behavior, and common austenitic stainless steels work-harden during deformation. Greater depth also changes the forming demands. Material, sheet thickness, blank size and tooling radii therefore guide the required force and drawing sequence together.

Send Han Chang a pot or basin photo or drawing, the sheet material, thickness and approximate dimensions. Existing die dimensions and your preferred removal arrangement are helpful additions. Mention any need for custom ejection so it can be included in the quotation discussion.

Han Chang’s press forms cement bricks, permeable pavers, road paving blocks, landscape bricks, wall masonry blocks and industrial floor bricks. Each application is matched to its brick mixture, mold and hydraulic pressing conditions.

Hydraulic pressing and pressure holding support control of brick thickness and density. Suitable mix moisture, fill quantity and tooling work with the press, while demolding arrangements help maintain edge integrity. Together, these support consistent quality and efficient production.

Compare the intended paver dimensions and mixture first, then mold footprint, cavity count, worktable space and pressing requirements. Include filling and demolding arrangements so the equipment choice fits the complete forming job, not just the nominal size of the press.

Brick-forming mixtures containing recycled material can be considered for production. The actual recycled content, cement and aggregate proportions, moisture and intended product guide the mold and pressing arrangement.

Cavity count and layout affect mold footprint and the quantity of product in a pressing operation. They also influence filling and removal arrangements. Match the complete tool, mixture and brick geometry with worktable space and pressing-force requirements when selecting equipment.

Brick dimensions, mold cavity layout, worktable requirements and the specified automation scope are key quotation factors. Demolding and handling arrangements also shape the configuration. Send Han Chang a brick photo or drawing with approximate dimensions to start an RFQ and compare the equipment on a clear, product-specific basis.

Han Chang’s press makes small rubber and solid silicone molded components and has upper demolding and lower demolding functions. Typical applications include O-rings, gaskets, cable grommets, caps, plugs, feet, buffers and silicone keypads, with tooling matched to the product and its release requirements.

Upper and lower demolding functions help accommodate different mold-release requirements. Compare the mold’s part-retention position, release direction and removal clearance alongside the pressing requirements. This helps make everyday part removal more practical and supports consistent handling of small molded components.

Yes. The machine supports rubber and solid silicone compounds. HCR silicone is loaded as a solid charge and cured under heat and pressure to produce components such as gaskets and keypad bodies. The compound’s hardness, cure system and processing requirements guide the molding conditions.

A rubber vulcanizing press applies heat and pressure to cure the rubber while the mold defines the part shape. This machine combines that compression-molding process with upper and lower demolding functions for small rubber and solid silicone components. Mold space, pressing requirements and part release are useful points to compare when choosing equipment.

Compression molding starts with prepared compound placed directly into an open mold. Injection molding feeds material into an already closed mold. Compare tooling investment, compound suitability, part geometry and planned volume, then include the labor and time required for loading, removal and finishing in the production-cost comparison.

Tonnage depends on molding pressure, total projected cavity area and tooling structure—not the size of one part alone. Output also depends on cavity count, charge preparation, cure time, removal and trimming. Matching the mold and demolding arrangement helps keep these operations coordinated for consistent quality and efficient production.

Start with a part drawing or photo, material and planned production volume. If a mold already exists, include its dimensions, cavity count and current removal method. Pressing requirements, heating, mold accommodation and demolding compatibility help define the equipment scope and quotation.
