1. Flow channel systematic design is based on theoretical calculation& practical conclusions, adopting reasonable compressing ratio and strain technology according to different formula and technique.

2. Multi-cavity separate feeding system design makes flow channel geometric smooth transition and no blind angle. Flow channel is highly polished to ensure best extrusion speed.

3. Calibrator uses high efficient vacuum device and cooling system design to guarantee great quality of finished products and smooth profile surface.

4. High-sealing vacuum water tank adopts floating setting design, able to adjust automatically.

5. Material of mold is high-quality stainless steel 2CR13, 3CR17, having the advantages of high hardness and long useful life after thermal refining.

6. The mold can be used as materials of high-grade plastic door, window and other architectural decoration.
