Cheap Price Top Quality Rubber Compression Mold

We provide OEM & ODM custom rubber compression molding tool service for rubber and silicone vulcanization. According to your 2D/3D drawings, samples or product requirements, we design and manufacture compression molds with single-cavity or multi-cavity structure.

This compression mold works with rubber vulcanizing press. Pre-weighed raw rubber compound is loaded into cavities. Under high temperature & high pressure, rubber flows, vulcanizes and forms finished rubber components. It is ideal for thick-wall, high-hardness, high-viscosity rubber parts.

Our mold supports NBR, EPDM, VMQ Silicone, FKM/Viton, HNBR, AFLAS etc. Widely used for O-rings, rubber gaskets, rubber bellows, grommets, shock pads and custom sealing components.

Our in-house mold workshop supports complete mold development from design, CNC machining, trial testing to final validation. Custom molds can be built for various rubber and plastic materials such as EPDM, NBR, FKM, Silicone and engineered plastics.

Whether you need a new mold for prototype sampling or mass production tooling, our engineering team will work closely with you to control quality, lead time and cost. We deliver reliable one-stop custom molding service for global buyers.

Quality Control and Testing for molds

Strict quality control procedures are implemented throughout the entire mold manufacturing process, from design review, CNC machining, heat treatment to final assembly.

Every mold will undergo rigorous inspection and bench testing before shipment. We check mold dimensions, surface finish, ejection system and sealing structure to ensure precision and stability. Trial molding is carried out to verify part quality, dimensional accuracy and material compatibility for rubber or plastic compounds.

Any defects will be corrected during the sampling stage. Only qualified molds are approved for mass production. Our QC team maintains complete inspection records, helping minimize production risks and guarantee consistent performance for your molded partst.

- P20 / 718: 100,000–200,000 shots

- H13 / SKD61: 300,000–500,000 shots

Q3: What rubber materials can your compression mold support?

A: Our mold is compatible with NBR, EPDM, VMQ Silicone, FKM(Viton), HNBR, AFLAS and other custom rubber compounds. Suitable for O-rings, gaskets, rubber bellows, grommets, vibration pads and custom sealing parts.

Q4: Can you make multi-cavity compression molds? Such as 64 cavities O-ring mold?

A: Yes. Single cavity & multi-cavity design are available. We optimize flash groove and venting system to reduce air trap and part defects. Common cavity options: 4, 8,16,32,64 cavities.

Q5: What is your mold lead time?

A: Simple mold: 7–12 working days. Complex multi-cavity mold:15–25 working days. The time starts after drawing confirmation and deposit received. Mold trial & sample test included.

Q6: What is your mold packing method for export?

A: We coat mold with anti-rust oil, wrap with anti-rust paper + bubble film and EPE foam. Then pack into fumigation-free plywood crate, loaded on wooden pallet with stretch film. Custom shipping marks are acceptable.

Q7: Can you modify the mold after mold trial?

A: Minor adjustments are available. If major structure change is needed, extra tooling cost will be quoted separately.

Q8: What about after-sales service for the mold?

A: We provide technical support for mold operation. Free repair for non-human damage within warranty period. We also support regular mold maintenance service.
