RA Series Rubber Injection Molding Machine

Overview

Dekuma brings 25 years of experience to every build and follows strict German manufacturing standards. That expertise gave rise to the RA Series, our dedicated solution for electrical insulator manufacturing.

Purpose-built for high-voltage composite rubber insulators, this molding machine handles complex shapes, large shot volumes, and demanding material properties with ease. Manufacturers value its proven efficiency, rock-solid stability, and versatile performance, making it the ideal machine for modern insulator production.

Characteristics

Advanced Material Plasticization and Injection System

Developed with German engineering expertise, this insulator rubber injection molding machine features advanced material processing and injection system. Its enhanced screw design ensures better, more consistent feeding of rubber compounds, while also achieving more uniform mixing (homogenization) and improved air removal (degassing).

Enhanced Energy Efficiency and Thermal Stability

Utilizes advanced double-layer thermal insulation plates capable of withstanding high pressure and temperatures. This robust design provides exceptional heat containment, directly reducing energy consumption by approximately 40%.

The result is not only significant energy savings but also increased machine reliability due to reduced thermal stress on components.

Robust and Reliable Hydraulic System

Equipped with top-tier components, including an American high-pressure pump and renowned German hydraulic valves.

This robust configuration delivers a hydraulic system characterized by outstanding stability and reliability, ensuring consistent operational accuracy, precise control, and dependable service life for silicone rubber high voltage insulators manufacturing.

Austrian B&R control system & 10.4″ TFT color screen

Offers intuitive operation and comprehensive process monitoring. This advanced control allows for precise setting, adjustment, and saving of all critical molding parameters, facilitating efficient setup, real-time monitoring, and stringent quality control during the production of insulators.

High-Precision Stroke Measurement

Achieves remarkable accuracy by utilizing world-class non-contact linear transducers for closed-loop control of both clamping and injection strokes. With a theoretical precision of 0.05%, this system ensures exact mold positioning, accurate shot size control, and precise switching points.
