There are more and more applications of abrasive steel. When manufacturing moulds, the mould steel must meet some working conditions, such as hardness, strength, wear resistance and sufficient toughness. Only the working conditions that meet the mould requirements are met. The mould can be used as a tool for the workpiece. Which mould steel performance […]

There are two main purposes for polishing the mould. One is to increase the brightness of the plastic mould and make it beautiful. The second is to make the mould easy to demould. In the polishing process, the surface of the machined mould cavity is generally roughened with coarse oil stone, and the tool marks

The failure of the stamping die has a close relationship with the resistance to congestion. The durability of the stamping die after working for a period of time, the working size is lost due to frequent wear and tear, and the technical conditions of the part can no longer be met. It is determined according

Different die materials have different strength, toughness and wear resistance. Under certain conditions, the use of * materials can improve the durability several times. For example, the watt-hour meter magnetic pole punching die made of T10A steel has much shorter primary grinding life than the similar die made of Cr12 and Cr12MoV. The average grinding

In order to ensure the quality of the workpiece, the quality of mould manufacturing must be improved, and high-quality moulds can be better used. To improve the quality of mould manufacturing, the following four aspects must be improved. 1.Improve the processing accuracy of the mould parts.The geometry of the working parts of the mould parts,

The so-called part processing accuracy refers to the degree of conformity between the actual geometric parameters (such as size, shape and position) of the part and the ideal geometric parameters after processing. The part processing accuracy includes dimensional accuracy, shape accuracy and position accuracy. Therefore, we must pay attention to the precision of the mechanics

In order to make any damage or abnormality after the injection moulding of the plastic mould, we need to carry out certain specifications for the injection moulding of the mould, and its main requirements meet the following six conditions: 1. mould closing pressure: In principle, it should be greater than the total pressure of the

In daily life, most of our common moulds are made of steel. When using mould steel, we will find that some defects will occur, which will cause the mould to be used normally, and even the manufactured workpiece will be deformed and used differently. Therefore, when using mould steel, we must understand its common defects

The mould makes us common workpiece casting tools, and the application field of the mould is very wide. What bothers us is that during the use of the mould, some damage often occurs, which has a lot of damage to the manufacture of the workpiece. Damage, some precautionary measures need to be taken. 1.Good casting

The use of mould steel is very wide, so the working conditions of mould steel must meet the height, strength, wear resistance, and sufficient toughness, as well as high hardenability, hardenability and other process properties. We need to know four important points about the performance of the mould. 1.Processability Refers to forging, rolling hot workability,
