Precision mechanical parts processing, not any material can be precision processing, some materials hardness is too large, across the hardness of the machine parts, may break the machine parts, so these materials are not suitable for precision machining, unless it is made of special materials, or laser cutting. So what are the material requirements for…
1, plastic mold working conditions Due to the development of plastics and plastic molding industry, the quality requirements of plastic molds are getting higher and higher, so the failure of plastic molds and their factors have become an important research topic. The main working parts of plastic molds are molded parts, such as convex molds,…
The injection molding process can be roughly divided into the following six stages: Close mold, shot glue, pressure protection, cooling, open mold, product removal. The above-mentioned process repeatedly, can be batch periodic products. The molding of thermosoplastics and rubber also includes the same process, but the barrel temperature is lower than thermoplastic plastic, injection pressure…
The time required to complete an injection molding process is called the molding cycle, also known as the molding cycle. It actually consists of the following sections: Molding cycle: The molding cycle directly affects labor rate and equipment utilization rate. Therefore, in the process, we should ensure the quality of the premise, as far as…
Position accuracy mainly refers to the coaxiality of the support shaft neck of the assembly drive as opposed to the support shaft neck of the assembly bearing, usually expressed by the radial round run-out of the support shaft neck with the matching shaft neck, and according to the requirements of use, the high precision shaft…
The precision injection molding is determined on the basis of the precision of the injection molding product, i.e. the dimensional tolerance, position tolerance and surface roughness of the product. There must be many related conditions for precision injection molding, and the most essential are the four basic factors of plastic materials, injection molding molds, injection…
Material mold is mainly used to make a variety of plastic products, in order to achieve the desired effect, in the design of plastic molds to consider a lot of factors. Since the final effect of plastic molds will be affected by various factors, including plastic shrinkage and error, wear and tear, so in the…
Plastic mold manufacturers in order to win the advantage in this fierce market competition, we must carry out reform and adjustment, especially in the plastic mold product quality, more attention should be paid to, because the quality of plastic mold will affect the quality of products, production, cost and so on. In order to enable…
Mold is a lot of manufacturers need to use, so for mold processing is also a lot of people’s concerns. Today, the mold processing plant will take you together to understand the common mold processing process what. At present, the main factors restricting the accuracy of mold processing are the precision requirements of the parts,…
Mold machining center for deep hole processing, often the processing of iron chips wrapped around the tool, if not cleaned will be more and more tangled will even throw out. Some operators may say that it is 2 000 to remove them manually by hand or hook, but the iron chip temperature at high speeds…
