Frequently Asked Questions

1. Can one machine produce different automotive rubber parts?

It depends on the mold change and process settings. Our automotive rubber injection molding machines support quick mold change and parameter presets(Feature availability varies by model. Please contact us for details), allowing flexible switching between different products and maximizing production line versatility.

2. Can the machine handle different types of rubber materials?

Yes. Material compatibility depends on the machine series and application. Across Dekuma's automotive portfolio, different configurations support materials including NR, NBR, EPDM, TPV, TPE, TPU, flexible modified PVC, and other rubber or elastomer compounds. Temperature and pressure systems can be customized for each material type.

3. Which machine is suitable for automotive seals and gaskets?

The suitable machine depends on the product structure, material, mold, injection volume, and production requirements. The RV Series is suitable for a wide range of automotive rubber components, while the RC Series is designed for precision applications such as weatherstrip corner joints and complex sealing parts.

4. Which machine is suitable for automotive glass encapsulation?

RV-B Series is developed for automotive glass encapsulation applications using materials such as TPV and TPE. It is suitable for products including quarter glass and automotive window encapsulation that require precise injection control and stable processing.
