Injection molding of rubber began in the mid 1960s. Rubber injection molding successfully alters the plastics process by heating the rubber and placing it under significantly more pressure per square inch of cavity surface in molding. This is different from the plastic injection molding process where the materials are cooled under less pressure. Through various innovations, injection molding has become one of the most efficient ways to create molded rubber products in many cases.
Advantages of injection molding:
- Reduced cycle time
- Flashless tooling
- Economical process for high volumes of medium to high precision components
- Capable of producing overmolded components
- Minimal material waste
We can make parts according to your tolerance requirements, if you do not have special requirements on the tolerance,our tolerance is according to the standard of ISO3302:2014 CLASS 2
With compression molding, we can make surface as matte, texture, common polishing, mirror polish, laser engraving, power coating, printing, segmented colors and mixed colors, from below picture, you can find effect of different surface treatment.

100% inspection for order,we seriously take care of the quality control from IQC to OQC, throughout each step of the production. Let us show you our quality control:
For raw materials, we’ll do the IQC in time. All materials are procured only from the verified suppliers, who have implemented and maintain certified quality management systems in their plants. With full certificates, such as RoHs, Reach, MSDS, FDA, LFGB, UL, EN549, BPA free, EN71, and so on;
For pre-production samples, we'll provide several pieces to our clients for assembly and function testing. We will seal the samples in time once they're approval.
For Bulk Production, we'll do the IPQCS & PQC (Multiple Sampling Inspection) during production and we'll do the FQC (Sampling Inspection) after deburr or breaking sharp edges. In order to timely find problems, solve problems, reduce defective products, reduce manufacturing costs.
After packing and assembling, we'll do the OQC (Sampling Inspection) to make sure the final goods are qualified.
