Frequently Asked Questions

1. How choose the right rubber injection molding machine for power industry applications?

The right machine depends on your component type and dimensions, rubber material, mold structure, required injection volume, clamping force, vulcanization process, and production target. Our technical team can recommend a suitable RA, RT, or RI configuration based on these requirements.

2. What power industry components can Dekuma machines produce?

Dekuma solutions cover composite insulators, long-rod insulators, hollow-core insulators and bushings, surge arresters, cable accessories, switchgear insulation components, and other injection-molded rubber parts used in power equipment.

3. What is the difference between the RA, RT, and RI Series?

The RA Series is designed for high-voltage and large insulation components using silicone rubber or EPDM. The RT Series focuses on long and large HTV silicone rubber components and features a top-opening mold structure. The RI Series is a practical solution for general insulators and long rubber products, with three-side access and optional double-station configurations.

4. Which rubber materials can DEKUMA power industry machines process?

Material compatibility depends on the machine series. Across the Power Industry portfolio, DEKUMA provides solutions for silicone rubber, HTV silicone rubber, EPDM, and other application-specific rubber compounds.

5. Can DEKUMA machines mold large or long power components?

Yes. DEKUMA offers different injection volumes, clamping forces, mold sizes, and opening strokes for products with different dimensions and material volumes. The suitable configuration depends on the component and molding process.

6. How can trapped air be reduced during rubber injection molding?

On applicable machine configurations, optimized plasticizing, homogenization, and degassing help reduce trapped air before and during injection, supporting more consistent molding quality.
