In the field of rubber and injection molding, customized products are becoming more and more popular among global buyers, as they can perfectly match specific application scenarios and meet unique product requirements. As a professional foreign trade supplier of rubber and injection molding products, we specialize in custom PU parts and PU injection molding services. This article will provide a complete guide for buyers, including what custom PU parts and injection molding are, the customization process, how to choose specifications, and why you should choose our factory, helping you smoothly complete the customization of PU products.

Custom PU parts refer to PU products customized according to the buyer’s specific requirements, including size, shape, hardness, color, performance, and application scenarios. PU injection molding is a processing method that injects molten PU material into a mold through an injection molding machine, then cools and shapes it to produce high-precision, uniform-quality PU parts. This processing method is suitable for mass production of custom PU parts and can meet the high-precision requirements of various industries.
We have a professional customization process to ensure that each custom PU part meets the buyer’s requirements. The specific process is as follows:
1. Requirement Communication: The buyer provides detailed requirements, including product size, shape, hardness, color, performance, application scenario, and order quantity. Our professional team will communicate with the buyer to confirm all details and put forward reasonable suggestions based on our industry experience.
2. Design and Mold Making: According to the confirmed requirements, our engineers design the product structure and mold, and make the mold with high precision to ensure the accuracy of the product.
3. Formula Customization: We adjust the PU formula according to the performance requirements of the product (such as wear resistance, oil resistance, high temperature resistance) to ensure that the product meets the application needs.
4. Sample Production and Testing: We produce a small number of samples, conduct strict performance testing (such as wear resistance, tensile strength, compression set), and send the samples to the buyer for confirmation.
5. Mass Production: After the buyer confirms the sample, we start mass production, strictly control the production process to ensure the consistency and quality of the products.
6. Inspection and Delivery: We conduct a full inspection of the finished products, pack them safely, and deliver them to the buyer on time according to the agreed terms.
When customizing PU parts, choosing the right specifications is crucial to ensuring product performance and application effect. Here are the key specifications to consider:
Hardness: PU hardness ranges from Shore A 30 to Shore D 80. Soft PU (Shore A 30-50) is suitable for buffers, gaskets, and cushions; medium-hard PU (Shore A 60-70) is suitable for seals, rollers, and industrial wheels; hard PU (Shore D 70-80) is suitable for wear-resistant parts and structural components.
Color: We can customize any color according to the buyer’s requirements, including transparent, black, white, and various colored PU parts, to meet the aesthetic and functional needs of the product.
Size and Shape: We can produce custom PU parts of any size and shape according to the buyer’s drawings or samples, with high precision (tolerance ±0.01mm) to ensure that the product fits perfectly with the equipment.
Density and Performance: According to the application scenario, we can adjust the density and performance of PU, such as improving wear resistance for industrial wear parts, improving oil resistance for oil-contacting parts, and improving high temperature resistance for high-temperature working environments.
