Plastic Injection Molding is a method of using an injection machine to quickly inject molten plastic into a mold and solidify to obtain various plastic products.
High mold cost but low single-piece cost;
Automotive plastic parts, consumer electronics plastic shells, etc.
Generally only suitable for mass production;
The surface accuracy is extremely high, and the shape error of the same batch of products is small.
After a period of production, the melting glue continuously takes away the heat, resulting in insufficient melting glue, high viscosity, and poor fluidity, making the product lack glue. It can be solved by increasing the temperature of the material pipe.
The ellipse of the product is due to the unevenness of the glue, causing uneven pressure around the product, making the product elliptical. Three-point glue can be used to make the product glue evenly.
The mold vent point is unreasonable, not only will not achieve the venting effect, but will cause product deformation or size changes, so the mold vent point should be reasonable
Due to the low melt temperature or low mold temperature and insufficient injection pressure, the glass fiber cannot be well combined with the plastic in the glue, causing pan-fiber to appear. At this time, the melt temperature and mold temperature should be increased to increase the injection pressure
