Plastic injection molding mold will appear a lot of difficulties, injection molding mold is composed of two parts of the moving mold and the fixed mold, the production of plastic products need to use the mold injection molding, is through the injection molding machine will plastic raw materials into the injection mold cavity, after cooling and curing to form the injection molding parts. In the mold manufacturing process, how to deal with the surface of plastic injection molding mold appears gloss defect? The following is the causes and solutions of the surface gloss defect of plastic injection molding mold and. Hope to help you. 1. The mold finish is poor, the cavity surface has rust, etc., the mold exhaust is poor. 2. The mold gating system has defects, should increase the cold well, increase the flow channel, polishing main channel, diverter and gate. 3.

Electric injection molding machine in the production of injection mold will encounter the situation of injection molding is not filled, there is a lack of glue at the bone position right Angle and fuse connection, here to share some experience. Analysis of glue injection is not filled: 1. The trapped air in the bone position makes the injection molding machine fill up. 2. The filling of the injection molding machine caused by the glue welding line is not filled. Reason analysis of glue injection is not filled: When the injection molding machine is working, the mold gluing method is two-point gluing, and the injection speed is too fast, which is easy to cause the gas trapped at the right Angle of the bone position and cause the filling dissatisfaction; If the injection speed is too slow, it is easy to fill the fuse at the end of the flow. The solution: Multistage injection molding and position switching. In the first stage, the medium speed filling channel was used to pass

Plastic injection mold is an important plastic processing tool, through which plastic raw materials are transformed into products of various shapes and specifications. The principle of injection mold can be summarized as the following steps: 1. Plasticizing and injection First of all, plastic raw materials undergo a series of processing treatments, such as drying, screening, mixing, etc., to become plasticized materials suitable for injection molding. In the heating barrel of the injection machine, the plastic begins to melt and plasticize under the action of heat, forming a uniform molten state. Subsequently, the plasticized plastic is pushed into the nozzle of the injection machine through the pushing action of the plunger or screw. When the plastic in the nozzle accumulates to a certain amount, the driving force of the injection machine stops, and the nozzle of the injection machine injects plastic into the pouring system of the mold.
