Single-Color Melamine Molding Machine

The Han Chang single-color press is a hydraulic compression molding machine for single-color melamine bowls, plates, cups, trays and other tableware. Its material capability extends beyond melamine molding compound to phenolic/Bakelite and urea-formaldehyde molding compounds, glass-fiber-reinforced thermoset compounds, rubber and silicone. The single-color press range therefore supports several material applications rather than melamine alone.

Each material needs suitable tooling, heating and molding conditions. The decal and glazing sequence used for melamine crockery does not apply automatically to these other materials. Tableware compounds and finished products must also meet the food-contact requirements of their intended market.

Yes. Single-color describes the molded body of the tableware, not the number of colors printed on its decal paper. The single-color press can mold a single-color body, run a separate decal stage for the required decoration, and then complete the glazing stage. Glazing powder is required for melamine tableware whether or not decals are used.

Choose the two-color press when the body itself needs two colors, such as a red-and-black upper/lower combination. Choose the three-color press for a three-color appearance across the top, bottom and rim. Separating body colors from printed decoration avoids specifying a multicolor press merely because a decal contains several colors.

The operator manually loads compound into the already-heated mold and starts the plain molding stage. The press automatically closes, applies pressure, degasses, forms the part and opens. The operator then adds glazing powder.

The operator starts a separate glazing program, which applies pressure to complete that stage. The mold then opens for manual product removal. Undecorated tableware still has two separately started stages, with manual glazing-powder addition between them.

After compound is loaded into the heated mold, the plain molding stage presses, degasses and forms the body. Once the mold opens, the operator adheres the decal paper to the formed piece and starts the separate decal program.

Only after the decal program finishes and the mold opens again does the operator add glazing powder and start the glazing program. The press then completes that stage, opens and allows manual product removal. The sequence is plain molding → decal → glazing, with paper and powder added separately. Decals depend on the decoration required; glazing powder is a necessary part of this melamine tableware process.

The single-color press groups mold closing, pressing, degassing, forming and opening into the relevant molding program. Once a stage is started, the press carries out its programmed actions rather than requiring the operator to control every hydraulic movement separately. Automatic molding cycles are a shared advantage of Han Chang’s melamine press range.

Plan output from pieces per mold, all required program and handling times, and daily working hours. Coordinate the press with compound preparation and finishing equipment to plan the complete production workflow.

The single-color press offers multi-stage degassing with a selectable count up to 99 and adjustable time and travel. These settings help factories match gas release to the molding compound, wall thickness and tool.

Set the degassing count to suit the material and mold, then coordinate mold temperature, pressure holding and charge weight to control surface finish and curing.

Start with the total projected area of all cavities and the compound’s molding-pressure requirement, then match the mold dimensions, weight, mounting and removal space. Single-color press specifications offer press forces from 37 to 800 Ton. Force rating and platen size answer different questions: one supplies molding force, while the other helps accommodate and support the tooling.

Han Chang can help select force, platen dimensions, daylight, stroke and heating from your product drawing or existing-tool information. Multi-cavity work also calls for sufficient total pressing force and a production plan covering the complete cycle.

Existing tooling is a useful starting point. Share mold photos and dimensions so Han Chang can match the mold height, weight, mounting, heating and part-removal clearance to a suitable press.

Reusing a mold is worth discussing before replacing tooling, with any mounting adapter or mold changes determined by the actual fit. A mold photograph, outside dimensions or the specifications of the existing press can start the discussion; a complete drawing package is not necessary for the first inquiry.

Choose the single-color press for a single-color molded body, with decals used where printed decoration is required. The two-color press makes upper/lower two-color bodies, such as red-and-black crockery. The three-color press presses the first, middle and outer color layers in sequence to create tableware with different colors on the top, bottom and rim; it is intended for three-color body designs.

Choose a cup molding machine when the product’s outer shape needs side-parting tooling and locking. Conventional vertical-opening products can suit a single-color press. Match body-color design and mold opening to the products you intend to make.

Yes. Han Chang can supply the equipment required for a complete melamine tableware line, including hot compression molding presses, high-frequency preheaters, edge-grinding machines, polishing machines and decal-paper drying machines. The offer extends beyond a stand-alone single-color press to one-stop equipment supply for the surrounding processes.

A new factory can discuss the line around its tableware range, body colors and planned output. An existing factory can add equipment for material preparation, molding or finishing. Discussing the linked stages through one equipment supplier helps keep the purchasing scope aligned with the production workflow.

Han Chang has factories in Taiwan and Mainland China. The Mainland China factory has customer-service and professional repair departments to support customers with equipment service and repair needs. Buyers can discuss service arrangements alongside the installation location and intended use of the press.

For assistance during operation, contact Han Chang through the official channels on this website with the machine model, equipment identification, a description of the problem and relevant photographs or video. These details help the service and repair teams understand the equipment and the reported issue.

Single-color press pricing depends on pressing force, platen size, tooling space, stroke, heating and the equipment configuration required. Presses with the same force rating can have different working space and equipment content. A stand-alone press quotation also differs from a package including preheating, edge grinding, polishing and decal-paper drying equipment.

Start with a product photograph, compound name, mold dimensions or details of your existing press. Body-color requirements, cavity count and planned output can then help define the configuration and supply scope. You do not need to know the correct tonnage before contacting Han Chang about a melamine crockery production project.
