Piston Needle Valve

The Superiority of Piston Needle Valve System

• Maximum use of raw material

Different from conventional runner and sprue, the piston needle valve is closed after the exact amount of LSR (Liquid Silicone Rubber) has been injected into the cavity, then prevents producing wastes while manufacturing.

• Minimum time of LIM (Liquid Injection Molding)

Without having to consider the curing time of the runner and sprue, the cycle time is decreased, then remarkably increases the capacity.
