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.
Higher Products Added Value, Increasing Production Cost.
TCW SERIES:
