Cavity layout: There are two ways to rank plastic parts in the mold, one is that the mold number is one product, and the other is that the mold number is two products. (injection molding products). The first type of elastic flanging hook uses side core pulling, which also helps to solve the problem of plastic parts adhering to the fixed mold; the second type of elastic flanging hook is directly inserted into the fixed mold of the movable mold with an inclination to form. Cancel the side core pulling, and do a skin texture treatment on the side wall of the movable mold to increase friction, so that the plastic part stays on the movable mold when it is out of the mold. (Injection molding machine parts).

Mold structure: The function of the gating system is to allow high-temperature melt to enter the mold cavity at high speed under high pressure to achieve cavity filling. The solidification time of the plastic raw materials, the aperture of the gate, and the selection of the diameter of the runner connecting with the gate are all factors that affect the mold.

For mold temperature control system design, for thin-walled, long-flow plastic parts, (Injection Molded Plastic Parts), the recommended mold temperature is 80-90℃. Increasing the mold temperature can stabilize the size and improve the appearance quality, but affects the molding shrinkage rate. Therefore, the mold temperature must be uniform, and the cooling of the mold must be strengthened to ensure a balanced cooling. Thin-walled injection molding molds generally need to have good air exhaust. (plastic injection mold making).
