High Speed Extrusion Mould
After years of experience accumulation, our company can design PVC/UPVC high speed extrusion die, main profile extrusion speed can be as high as 7 m/min, or even higher. Double cavity mold, main profile extrusion speed up to 5 m/min. Which applied to window profiles, profiles, wall boards and decorative materials. The use of high-speed extrusion molds can help manufacturers improve production efficiency, reduce production costs, and improve the competitiveness of enterprises.
1. Design of the Die head
Is generally independent of the duct flow in a high speed extrusion flow channel, surface and surface, especially the hook slot, inner ribs and surface must be separated by 0.5 ~ 1.0 mm thick separated reinforcement, this separation is not only the material flow in the flow channel are channeling, to reduce the interface stress, material flow is beneficial to improve the extrusion speed, but also convenient for repairing mold, produce section everywhere and clear and pleasing to the eye.
2. Mold setting
The total length of the high speed extrusion die is much longer than that of the low speed extrusion die. It consists of short dry mold and long wet mold. High speed extrusion shaping mold Main profile dry shaping consists of two to four sections of 230mm long shaping mold, small profile is composed of one to two sections of 235mm long shaping mold.The water tank consists of two to six meters of strong eddy current water tank.
