Double-Station Sliding-Plate Compression Molding Machine
Han Chang manufactures double-station sliding-plate compression molding machines that bring rubber and silicone molds into the handling area for loading, cleaning and part removal, then return them for heated hydraulic pressing.

Machine advantages
A press must fit both the mold and the work around it. Sliding plates are especially useful when operators place individual charges across multiple cavities or need room to lift a flexible gasket or pad from the mold.
Bring loading within easier reach
Moving the mold out of the pressing area gives operators a clearer view of cavities and parting surfaces for placing charges and cleaning between cycles.
Make room for part removal
Gaskets, flexible silicone pads and small multicavity parts can be handled at the extended mold position instead of deep inside the pressing area.
Organize work around two stations
Two molding positions let factories plan handling around cure time, tooling and available operators in a shared equipment layout.
Match heat and force to the compound
Heated platens and hydraulic pressure support rubber vulcanization and silicone compression molding. Cure settings follow the compound, part thickness and mold design.
Compression molding and mold handling
Bring the mold out and load
Move the mold to the handling position, prepare the mold surface and place the rubber or silicone charges.
Return the plate and close the mold
Bring the mold back into the pressing position and close the tooling for molding.
Apply heat and molding force
Transfer platen heat into the mold and maintain hydraulic force for the compound’s molding cycle.
Open, slide out and remove parts
After molding, open the mold and bring it to the handling position. Remove the parts and prepare for the next charge.
Rubber and silicone applications
Han Chang double-station sliding-plate compression presses mold rubber gaskets, grommets and cushioning parts, as well as silicone keypads, membranes and household products. Sliding plates bring the mold into the working area for accessible loading, removal and cleaning, especially with multi-cavity tooling.
O-rings, flange gaskets and equipment seals
Molded products include O-rings, flat sealing washers, flange gaskets, pump-cover seals and valve sealing pads. NBR is a common starting point for oil-resistant seals; EPDM is often considered for outdoor sealing applications.
Gasket contours, bolt holes and cavity layouts shape material placement. Sliding access makes it easier to position charges, collect molded parts and inspect parting lines.
Silicone keypads and electronic enclosure seals
Solid-silicone products include remote-control keypads, industrial control-panel keymats, button dust membranes, connector seals and enclosure gaskets. Compound hardness helps define key feel, elastic return and sealing behavior.
Keypad mats and enclosure membranes need clear charge placement across the tool. Sliding access helps with loading, collecting thin parts and cleaning small grooves.
Machine feet, rubber bumpers and vibration pads
Produce equipment feet, appliance anti-slip pads, impact bumpers, cushioning washers and resilient pads. Natural-rubber and SBR compounds are common choices where elasticity and wear performance guide material selection.
Machine feet, stops and cushioning pads can use multi-cavity molds. Sliding access supports cavity-by-cavity loading and collection; compound hardness suits the support or damping duty.
Cable grommets, wiring boots and protective caps
Examples include panel grommets, wiring-harness boots, connector dust caps, rubber plugs and mechanism covers. These parts protect cables at panel openings and shield exposed connections or moving assemblies.
Small grommets and caps combine holes, flanges and sealing lips. An accessible mold helps operators place charges around cores and clean the working surface.
Silicone coasters, baking molds and wearable parts
Consumer-product examples include silicone coasters, heat-resistant mats, baking molds, soft grips and wristbands. Tool surfaces create the required contours and textures; compound, color and hardness determine the intended feel and use.
Coasters, heat-resistant mats and baking molds may have textured or grooved surfaces. Sliding access aids loading and cleaning. Food-contact products require suitable compounds and compliance testing.
Suction cups, flexible diaphragms and bellows
Matched tooling can produce handling suction cups, pump or valve diaphragms, rubber bellows and silicone protective boots. Cup lips provide contact, diaphragms flex during operation, and bellows protect assemblies while allowing movement.
Suction cups and diaphragms use tooling matched to their curved profiles. For deeper parts needing additional demolding assistance, the sliding-plate model with ejection is another option.

Allow for mold movement as well as mold fit. Mold dimensions, weight and opening method help determine the platen, opening clearance and sliding space needed for practical operation.
Tooling and equipment quotations
Send a part drawing or mold photo and the compound. Han Chang can help match molding force, heated platens and the handling arrangement before quoting the equipment.
A mold-tilting function can be customized when tooling needs it for loading or removal. Describe this opening motion separately from the sliding-plate movement.
Buyer questions
What products can a sliding-plate compression molding machine make?
With suitable compounds and tooling, Han Chang double-station sliding-plate compression presses can make gaskets, O-rings, rubber washers, cable grommets, protective caps, machine feet, bumpers, silicone keypads, enclosure membranes, suction cups, coasters, heat-resistant mats and baking molds. Sliding plates bring molds into an accessible working position for multi-cavity loading, removal and cleaning.
Why choose a sliding-plate compression press?
Sliding plates bring the mold out of the pressing area for more accessible loading, cleaning and removal. This is useful for multicavity charge placement, flat gaskets and repeated mold-surface preparation.
Can this press mold both rubber and silicone?
Yes. Both materials can be compression molded on this machine with suitable compounds, tooling and cure settings.
Is sliding-plate movement the same as ejection?
No. A sliding plate moves the mold to the handling position; ejection helps release parts through a compatible mold mechanism. Compare the sliding-plate and ejection machine if your tooling needs that assistance.
When should I consider a vacuum press instead?
Choose around the production task: sliding plates address access to the mold, while vacuum equipment extracts gases during molding. Part venting requirements and handling needs guide the choice.
How do I select a press for an existing mold?
Use projected area, cavity count and molding conditions to establish force requirements. Check mold dimensions, thickness, weight and movement clearance against the platen and opening.
How should the two stations be used in production?
Plan the working sequence around each mold’s cure time, loading and removal steps and operator availability.
Can mold tilting be included?
Yes, a mold-tilting function can be customized to customer requirements and the tooling’s opening arrangement.
What do I need for a quotation?
A part or mold photo, dimensions and compound are a useful start. Available mold weights, cavity counts and production requirements help define the equipment configuration.
