-
Vertical Clamp & Injection Design
The gravity-assisted vertical structure ensures stable material flow and precise insert positioning during mold closure, significantly reducing defects and ensuring repeatable molding cycles. -
Precision Material Control
Advanced hydraulic or servo-electric systems provide granular control over injection speeds and pressure profiles. This results in accurate material flow and clean, minimal-flash silicone parts, regardless of material viscosity. -
Temperature Stability
Specialized barrel and platen temperature controls maintain uniform heat distribution, which is critical for reliable LSR curing and long-term part consistency. -
Flexible Automation Compatibility
Our systems integrate seamlessly with manual loading, robotic arms, or fully automated handling units to support high-throughput, stable production environments.
