The basis for determining precision injection molding is the accuracy of the injection molded product, that is, the dimensional tolerance, shape tolerance and surface roughness of the product. There are many relevant conditions for precision injection molding, and the most essential are the four basic factors of plastic materials, injection molds, injection molding process and…
Tube laser processing: Compared with traditional processing methods, this method reduces man-hours and processing costs; it can be processed into free designs, including complex shapes. Fiber laser processing: equipped with a 5 kW laser oscillator, this machine can process a variety of non-ferrous metals, such as stainless steel, aluminum, copper and brass, which has been…
Sheet metal processing is more and more liked by many users. For the processing process, each processed product must have a processing process. Of course, sheet metal processing is no exception. What is it and how is it processed? Let’s talk about the process steps of sheet metal processing for everyone: 1. The design department…
One of the common manufacturing processes today is precision sheet metal processing. Precision metal plate manufacturing describes any of various processes for forming metal plates into finished products. Almost all industries rely on some form of precision sheet metal processing, aerospace, military, automotive, pharmaceutical, medical, electronics, food service, telecommunications, computer, storage, and construction industries. Service…
Many work industries need to carry out sheet metal processing operations, this work contains more content, such as including blanking and material bending forming and other processing processes, in the process of these processing procedures, operators must pay attention to whether the parameters Accuracy and whether the application method meets the standard requirements. At present,…
In addition to the above applications for laser cutting, some miniaturized plastic molds also use laser processing to stop engraving and manufacturing. Laser engraving and the production quality is also quite high. According to the fundamental processing method of sheet metal parts, metal laser engraving, such as cutting, bending, stretching, forming, welding. According to the…

1. What should I do if there are a lot of bubbles in the mold silicone during the mold opening? This situation should be handled according to the conditions. In the presence of a vacuum pump, the silica gel and the curing agent must be mixed evenly before the vacuum treatment. If there is no…
1. Reasonable use of cooling lubricant, play the three major roles of cooling, washing and lubrication, keep cooling and lubrication clean, so as to control the grinding heat within the allowable range to prevent thermal deformation of the workpiece. Improve the cooling conditions during grinding, such as the use of oil-immersed grinding wheels or internal…
Die casting (note that die casting is not the abbreviation of pressure casting) is a metal casting process, which is characterized by using a mold cavity to apply high pressure to the molten metal. The mold is usually made of a stronger alloy, and the process is somewhat similar to injection molding. Sand mold casting…
The mold designer must have rich design and injection molding experience. For precision mold processing, the relationship between these influencing factors and the injection conditions and their apparent factors must be considered, such as injection pressure and cavity pressure and filling speed, injection melt temperature And mold temperature, mold structure and gate form and distribution,…
