30 years of Leading Experience in Multi-Resin.
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 injectiob.These unique technology afford our customers more diversify either production pattern or product designs.JONWAI sincerely hope these updaye multi-resin injection technology could assist our customers.
- Vertical Rotary Table System ( standard )
- Rotary Plate System ( option )
- Core-Puller Sliding System ( option )
- Parallelized Injectio ( option )
Clamping unit feature
- Reinforced plat’en in box structure design by FEA analysis to improve the platem 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.
- 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.
- Twn – rail injection seat drive former pulling cylinders*2 to ensure the nozzle centrality.
- High – mixing screw ensure material well mixing.
- Injection close loop for high precision molding.
- Injection accumulator maximum speed to 900mm/second.
- Servo motor system, energy saving 35% ~ 80%.
- Vertical Rotary table system (standard).
- Rotary plate system (optional function).
- Rotary mechanism drives by hydraulic motor system, pressure and flow – loop.
- 2 step pressure and speed control for rotary mechanism.
- Mechanical safety position stopper.
- Hydraulic safety position cylinder with limit switch.
- Rotary speed is lower than 1 second. Based on table diameter 760mm in 180 degree index.
Rotary Location precision:under +/- 0.025mm
- Core – Puller sliding 2 color system available (optional function).
- Cooling system distribute from the center of rotary table.
