Rubber injection molding and rubber compression molding are two popular methods used for the production of rubber parts. While both methods have their advantages and disadvantages, rubber injection molding is often preferred over rubber compression molding for several reasons. That’s why we Zhongxiang Rubber uses rubber injection for all products.

One of the main advantages of rubber injection molding is the precision and repeatability it offers. The process involves injecting rubber material into a closed mold cavity under high pressure, which allows for consistent and accurate production of parts with tight tolerances. This makes it an ideal process for the production of parts with complex geometries or tight dimensional requirements. In contrast, rubber compression molding relies on the compression of the rubber material within a mold, which can result in more variation in part dimensions and tolerances.

Another advantage of rubber injection molding is the reduced cycle times. The process involves preheating the rubber material before injection, which reduces the time required for curing and cooling. This allows for faster production cycles, leading to higher productivity and lower production costs. In contrast, rubber compression molding requires a longer curing time, which can increase production costs and reduce productivity.

 In addition, rubber injection molding allows for better material utilization and reduced waste compared to rubber compression molding. The injection process ensures that the material is distributed evenly throughout the mold, minimizing the chances of air pockets or other defects that may lead to scrap. This results in a higher yield of usable parts and less material waste. In contrast, rubber compression molding can result in more scrap due to uneven material distribution within the mold.

 Rubber injection molding also allows for the use of a wider range of materials. The injection process allows for better control over the temperature and pressure, which allows for the use of materials with higher viscosity or those that require higher curing temperatures. This makes it possible to produce parts with a wide range of mechanical properties, including high strength, abrasion resistance, and flexibility. In contrast, rubber compression molding may be limited to materials with lower viscosity and lower curing temperatures.

Overall, rubber injection molding offers several advantages over rubber compression molding. It provides greater precision, faster cycle times, better material utilization, and a wider range of materials. These benefits make it an ideal choice for the production of high-quality rubber parts. However, rubber compression molding may still be preferred for certain applications, such as those requiring lower production volumes or lower tooling costs.
