Clamping Unit

1 .Toggle adopting the conjoined structure, improving the hardness of toggle, ensuring the uniform of toggle manufacture-size, minimizing the gap between pipe and pin, improve the accuracy and application life of toggle.

2.First clamping platen using the box-type structure design, (thicken the thickness of platen, improving the hardness of platen, efficiently minimizing the deform caused by the force of tie bar.

3.Unique third-platen flange design, when the third- platen deforms by the pressure, by the support of flange and tie bar. a reverse torque will minimizing the deform of the third-platen.

4. Adopting gear-adjusting ring with high-precision, large-scale transfer and compact structure to facilitate customer adjusting (the mold thickness in manual or automatic mode.

5.Steel bush in clamping unit adopts new structure, arrange rational holes of graphite to improve the effect of steel bush lubrication and the wear-resistance, reduces the usage of lubrication oil.·

Injection Unit

1 .Injection unit adopts double-cylinder design, more higher injection pressure, more simpler structure and lower malfunction rate.

2. Enlarged-cylinder, adopting two-cylinder design, effectively prevent the adhesive- material leaking phenomenon caused by the machine vibration or other reasons while the nozzle is under high-speed operation.

3. Adopting graphite bush, improving the wear- resistance, reducing the frequency of using lubrication oil, effectively improve the cleanness of the injection part.

4.Injection cylinder adopts low-frictional seals, improving the response rate and improve the stability under the complicated processes of injection.

5.Bridge-style design, for different L/D ratio plasticizing parts.
