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:

  1. Vertical Rotary Table System ( standard )

  2. Rotary Plate System ( option )

  3. Core-Puller Sliding System ( option )

  4. Parallelized injection ( option )

Clamping unit feature

  • Reinforced platen in box structure design by FEA analysis to improve the platen

Strength and durability, and reduce the deformation.

  • The internal 5 points toggle clamping system through advanced analysis, the structure of toggle is solid and reliability.

  • Unique toggle pin and bush design reduce the toggle surface pressure.

Superior bush cannelure layout spread out lubricants effectivery.

  • The design is without using bracket on the rear platen.

  • Larger tie-bar diameter and pre-hardened steel to be used, with unique screw and nut design to reduce the inner – strength on tie bar thread. Avoid tie bar broken.

  • Wide movable platen support and unique trail design optimum platen parallelism even the heavy mold.

  • To minimize the toggle pressure and tie bar stress.

  • Lower platen deformation and eccentric magnitude to prevent the stress concentration and increase the durability.

  • Platen and toggle structure, enhance the reliability.

  • Extra wide platen and tie bar space design.

  • Optimum platen parallelism.

 

Injection unit

  • Parallel and horizontal injection units, easy to operate and maintain, more space saving.

  • Single injection cylinder design, power direct and stable RPM.
