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.
- Vertical Rotary Table System (standard)
- Rotary Plate System (option)
- Core-Puller Sliding System (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 effectively.
- 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 reinforce, enhance the reliability.
- Extra wide platen and tie bar space design.
- Optimum platen parallelism
- Parallel and horizontal injection units, easy to operate and maintain, more space saving.
- Single injection cylinder design, power direct and stable RPM.
- High plasticizing capacity and stable injection pressure to ensure quality molding.
- Twin-rail injection seat drive former pulling cylinders *2 to ensure the nozzle centrality.
