JONWAI – TCW Series

Rotate Platen

The rotating platen rotates the mold with 180 degree within 1 sec.  Unique hydraulic rotating system delivers the powerful force and precise control.  The strong mechanical design makes the rotating parts strong and durable.

Double Injection Unit

Double screw and barrel design, TCW machine can injection the two different materials with different colors.  With the precise shot weight control, it’s suitable for medical and autoparts applications.

CORE FEATURES

JONWAI – 30 years of Leading Experience in Multi-Resin Molding Technology.
In 1982 , JONWAI introduce the 1st 2-color injection molding machine in Taiwan,
Through decades of R&D in multi-resin injection technology, JONWAI have successfully developed several methods of multi-component injection.
These unique technology afford our customers more diversify either production pattern or product designs.
JONWAI sincerely hope these update multi-resin injection technology could assist our customers.
