DEKUMA RV Se SERIES
RUBBER INJECTION MOLDING MACHINES FOR AUTOMOTIVE AND TECHNICAL APPLICATIONS
Dekuma RV Se Series rubber injection molding machines are advanced injection solutions developed specifically for the production of high-precision rubber components for the automotive industry. Thanks to stable injection control, high clamping force, and excellent process repeatability, the RV Se series is widely used in the manufacturing of automotive sealing elements, vibration dampers, technical rubber parts, and functional elastomer components.
The RV Se series combines the mechanical robustness and injection performance of the standard RV series with a press structure and process control system optimized specifically for automotive applications, delivering maximum quality and productivity in mass production.
DESIGN PHILOSOPHY AND GENERAL STRUCTURE OF THE RV Se SERIES
Dekuma RV Se series machines are designed according to the vertical clamping - vertical injection principle. This configuration ensures homogeneous distribution of the rubber material within the mold and significantly improves filling quality, especially for automotive parts with complex geometries.
General design features include:
• High-rigidity, stress-relieved steel machine frame
• Press structure optimized for automotive applications
• Clamping mechanism providing precise platen parallelism
• Durable mechanical design suitable for long curing cycles
• Open architecture suitable for automation and robot integration
This structure maintains excellent process stability in high-volume automotive production.
RUBBER INJECTION TECHNOLOGY AND OPERATING PRINCIPLE
In RV Se series machines, the rubber compound is prepared in the plasticizing unit under controlled conditions. The screw and barrel geometry is optimized to prevent premature vulcanization and thermal degradation of the rubber. The prepared compound is then injected into the mold under high pressure.
Process steps include:
• Plasticization of rubber under low shear stress
• Stable and controlled injection
• Mold clamping under high clamping force
• Vulcanization and curing
• Automatic or semi-automatic part removal
This process ensures high surface quality and dimensional consistency, particularly when processing automotive elastomers such as EPDM, NR, SBR, NBR, and similar materials.
