Plastic Compression Molding Service
We Offer Plastic Compression Molding Service Specific to Your Needs!
Plastic compression molding is a process where preheated plastic material is placed into a heated mold, pressed under high pressure, and formed into precise, durable components. It’s ideal for producing large, thick, or high-strength plastic parts with excellent surface quality.
We work closely with our customers at every stage—from material selection to final inspection—to make sure each part performs exactly as expected. Our experienced team handles the technical details so you can focus on your product’s success.- In-house mold design and manufacturing
- Capable of molding large and thick-wall parts
- Consistent quality for both small and large runs
- Excellent surface finish and dimensional accuracy
- Fast lead times and flexible order quantities
- Competitive pricing and efficient production cycles
Plastic Compression Molding Process
Available Plastic Compression Molding Materials
Not all plastics are suitable for this method. We currently specialize in PTFE and UHMWPE, which perform exceptionally well under compression. Other composite materials can also be evaluated and produced upon request.
- PTFE
- UHMWPE
Plastic Compression Molding Components
Plastic compression molding is ideal for producing durable, wear-resistant, and precisely formed parts from PTFE and UHMWPE. These materials are commonly used where low friction, chemical resistance, and dimensional stability are required. Some of the products we produced include,
- Sealing rings and gaskets
- Valve seats and diaphragms
- Bearing bushings and sleeves
- Wear plates and guide rails
- Insulating washers and spacers
- Pump and compressor components
- Custom machined blocks and discs
Features of Plastic Compression Molding
-
Advantages
- It can produce large, thick, or complex parts with excellent dimensional stability.
- The process generates minimal material waste, making it cost-efficient for certain applications.
- It allows precise control of pressure and temperature for consistent part quality.
- Molded parts have good surface finish and uniform density.
- It is suitable for high-performance materials such as PTFE and UHMWPE.
-
Disadvantages
- The production cycle is slower compared to injection or extrusion molding.
- It requires preheating of materials and longer curing times.
- The process is less suitable for high-volume, small-sized parts.
- Mold design and setup can be more time-consuming.
- Limite material range as not all plastics are compatible with compression molding.
