Injection mold is an important process equipment for the production of various industrial products. With the rapid development of the plastic industry and the promotion and application of plastic products in aviation, aerospace, electronics, machinery, ships and automobiles and other industrial sectors, the requirements of products on molds are also increasing. With the coming of […]
High corrosion resistance Many resins and additives have a corrosive effect on the surface of the cavity. This corrosion causes the metal on the surface of the cavity to corrode, peel off, deteriorate the surface condition, and deteriorate the quality of the plastic parts. Therefore, use corrosion-resistant steel, or carry out chrome plating and cymbal […]
Today, the application of plastic products is quite extensive, and the production process of plastic products has not been improved. As we all know, the main production method of plastic products is injection molding. We will provide you with detailed information on injection molding processing. Injection molding process product molding cycle, including injection molding time […]
In addition to defects such as cracks caused by stress release, set deformation caused by uneven shortening, and fusion lines in some parts, medical precision injection molds also have various appearance defects due to improper mold design or process control. Common surface defects include surface silver, bubbles, dark lines, dark spots, surface depressions, black corners, […]
The medical plastic products industry is an emerging industry developed with modern medicine, and has attracted much attention for its high technology, high added value, high growth rate and broad market. With the development of medical devices, medical plastic products are playing an increasingly important role in the medical industry. Can be divided into the […]
If you spray paint on the surface of plastic products, you can ensure the brightness of the product. Plastic products are difficult to reflect. Therefore, the plastic parts look darker, and if the skin texture on the surface of the plastic parts is added, it will be even darker. So some customers will spray a […]
Plastic molds have become the most widely used applications in various fields. Plastic molds have always met market demand with excellent practical applications. Do you know how to judge the quality of injection molds? It is mainly reflected in six aspects. Mold life: on the premise of ensuring product quality, the number of working cycles […]
There are three ways of heat transfer: radiation, convection and conduction. In the mold, the heat generated by the plastic brought into the mold is 95% absorbed by the mold through conduction, and about 5% is emitted into the air by radiation and convection. During the processing, the temperature change is the most important influencing […]
We often see text and patterns on plastic products. These modifications make the products more vivid. There are many ways for manufacturers to make text appear on the products when they produce products, such as silk screen printing, hot stamping, pad printing, etc. The craftsmanship of lettering on the mold. Engraving on the mold, and […]
After the mold is processed, the surface of the mold will be left with CNC machined knife marks or electric discharge fire patterns. At this time, the mold needs to be polished. Polishing can improve the finish of the injection molded product. The mirror spark machine can also do this. One point, but general manufacturers […]
