Temper Brittleness Of Steel 1. Temper brittleness refers to the phenomenon that the toughness of the quenched steel decreases after tempering. When the quenched steel is tempered, the hardness decreases and the toughness increases as the tempering temperature increases. However, in the relationship between tempering temperature and impact toughness of many steels, two valleys appear,…
DetailsMold Meets Process Performance Requirements Mold manufacturing generally involves several processes such as forging, cutting, and heat treatment. In order to ensure the quality of the mold and reduce the production cost, the material should have good forgeability, machinability, hardenability, hardenability and grindability; it should also have small oxidation, decarburization sensitivity and quenching. Deformation cracking…
DetailsHow Is The Life Of The Mold And The Structure Related? In the actual application, the factory often determines that the mold has failed when the cost of re-maintenance reaches about 1/3-1/2 of the re-production cost, and then the repair is often not worth the loss. The failure of the mold is divided into abnormal…
DetailsABS Plastic Injection Molding Process Knowledge 1. Drying of ABS plastic ABS plastic has high hygroscopicity and sensitivity to moisture. It can be fully dried and preheated before processing. It can not only eliminate the fireworks-like bubble and silver wire on the surface of the workpiece caused by water vapor, but also help plastic plastic.…
DetailsGeneral Process Of Mold Processing The process of mold processing is relatively complicated, generally including mold blank preparation → part roughing → semi-finishing → heat treatment → finishing → cavity surface treatment → mold assembly → machine debugging. In the blank preparation stage, the corresponding blanks are provided for the mold parts, and the processing…
DetailsWhat Specifications Should Be Followed For Mold Design? 1. Material selection The greenness of the mold material has a very important impact on the green performance of the final product. The choice of materials for green design must be based on green materials, abandoning the chemical methods used to surface the materials in the past,…
DetailsThe Mold Meets The Working Conditions 1. When the wear-resistant blank is plastically denatured in the cavity of the mold, it flows and slides along the surface of the cavity, causing severe friction between the surface of the cavity and the blank, which causes the mold to fail due to wear. Therefore, the wear resistance…
DetailsMold Design Process And Factors To Consider Mold design refers to the digital design of the enterprise mold, including the cavity mold and the cold die. On the basis of the traditional mold design, the digital design tool is fully applied to improve the mold design quality and shorten the mold design cycle. The mold…
DetailsCommon Terminology For Mold Design 1. Stamping: The stamping is the collective name of the billet after one or more stamping processes, which is the collective name of the workpiece and the workpiece. 2. Glossy: Glossy is a bright section of the blank that is cut out. 3. Rebound: There are two kinds of rebound,…
DetailsTips For Selecting The Location Of Injection Mold Gates 1. Gate location requirements (1) Appearance requirements (gate marks, weld lines); (2) Product function requirements; (3) mold processing requirements; (4) warpage deformation of the product; (5) The gate capacity is not easy to remove. 2. Impact on production and function (1) FlowLength determines the injection pressure,…
