Heat Treatable And Non-Heat-Type Material Classification Generally, which mold material is selected is determined by the composition of the molding resin and the number of die casting. That is to say, the amount of glass fiber in the resin (hereinafter referred to as GF) and the amount of die casting are important factors in selecting…
Heat Treatment Conditions And Mold Quality The mold subjected to heat treatment is deformed during quenching and tempering. Therefore, it should be cooled as quickly as possible in order to meet the heat treatment quality requirements. This is in contradiction with the need to resist the deformation as slowly as possible. It is necessary to…
How To Properly Maintain Rubber Molds Everything has a certain life span. In order to extend the service life, we need to know how to maintain it properly. The following is about the correct maintenance of rubber molds. First, the regular maintenance of the mold wear curve is present in each mold. Mold repair is…
Cutting Tool Selection The material used to make the tool must have high high temperature hardness and wear resistance, necessary bending strength, impact toughness and chemical inertness, good processability (cutting, forging and heat treatment, etc.) and not easily deformed. Generally, when the hardness of the material is high, the wear resistance is also high; when…
High-Speed Cutting Will Become A New Process For Cutting New cutting processes such as hard cutting and dry cutting, which are represented by high-speed cutting, have shown many advantages and strong vitality. This is the requirement of manufacturing technology to improve machining efficiency and quality, reduce costs, and shorten development cycle. Therefore, the development of…
What Is A Mold? The mold is a product tool formed by using its specific shape and size. The raw materials used are different for the different products, and the molding methods are also different. The mold is divided into a die-casting mold, a glass mold, a metal stamping mold, a plastic mold, and the…
What Are The Current Advanced Technologies For Injection Molds? At present, the advanced technologies for injection molds at home and abroad mainly include the following: 1. The hot runner technology system is an important part of the mold production. The working principle is to install the manifold and the hot nozzle in the injection mold.…
What Are The Processing Methods Used In Rapid Prototyping Technology? Rapid prototyping technology has been developed to the present day, and its rapid integration has been developed with its high integration, high flexibility and high speed. The traditional rapid prototyping technology uses a “removal” method, that is, partially removes the material on the blank larger…
Micro Injection Molding Technology The micro-injection forming technology can be divided into two types according to the use of material objects, one is micro-injection molding technology using plastic as an injection material, and the other is powder micro-injection forming technology using metal powder as an injection material. Micro-injection molding technology is actually the miniaturization of…
Causes Of Dnts In Plastic Mold Pprocessing 1. Dent. The reasons for the dent are as follows: 1) The mold cooling is insufficient, and the cooling time is insufficient, which may cause serious deformation. 2) This is also the case with insufficient internal pressure in the mold. 3) The thickness of each part of the…
