1 and 16mm2, it is advisable to test the mold core with wires, and the wires should pass through the mold core. Don't be too big, or it will cause the glue to pour.

2. When vacuumizing and extruding, the mold should be suitable and not too big. If it is too large, the insulating layer or sheath layer is prone to ears, edges and loose sleeves.

3. In the process of extrusion, in fact, all plastics are stretched, and the actual stretching of general plastics is about 2.0 mm ... According to the drawings, consider the amplification value of the die sleeve. The amplification value of plastic mould sleeve with large draw ratio is greater than that of plastic mould sleeve with small draw ratio, such as polyethylene is greater than PVC.

4. Adjust the distance between the mold core and the mold kit when installing the mold to prevent blockage and equipment accidents.
