1. The requirements of the drawing die material require the mold working parts material to have good adhesion resistance (anti-seizure), high wear resistance and hardness, certain strength and toughness, and good cutting performance, and the deformation should be small during heat treatment.
2. Common materials for molds: yellow card materials, P20, 718, 738, S136. Generally, the basic requirements for injection mold materials are as follows: Easy to process Injection mold parts are mostly made of metal materials, and some structural shapes are very complex, in order to shorten the production cycle and improve efficiency, the mold materials are required to be easy to process into the shape and accuracy required by the drawings.
3. In the material selection of stainless steel plate punching die, the commonly used materials are tool steel, high-speed steel and stainless steel. The advantages and disadvantages of these three materials are compared below. Tool Steel Tool steel is a type of steel with good strength and hardness, which is often used to make tools such as molds, knives, etc.
4. Steel is a common mold material, which has the characteristics of high strength, high hardness and high wear resistance. Steel is divided into various types such as ordinary carbon steel, alloy steel, and tool steel. Ordinary carbon steel is suitable for making some simple molds; Alloy steel is suitable for manufacturing some complex molds; Tool steels are suitable for manufacturing some high-precision, high-demand molds.
5. What are the commonly used plastic mold materials? Plastic mold is an important tool for the production of various plastic products, often used in automobiles, home appliances, electronics and other industries.
1. The industry has classified semiconductor materials, and the silicon (Si) and germanium (Ge) mentioned above are the first generation of semiconductor materials. Silicon (Si): The silicon (Si) mentioned above is currently the most widely used semiconductor material, and integrated circuits are basically made of silicon (Si).
2. What are the semiconductor materials? Commonly used semiconductor materials are divided into elemental semiconductors and compound semiconductors. Elemental semiconductors are semiconductor materials made from a single element.
There are mainly silicon, germanium, selenium, etc., with silicon and germanium being the most widely used. Compound semiconductors are divided into binary, ternary, multivariant, and organic compound semiconductors.
3. Types of semiconductor materials Semiconductors are a class of materials with electrical properties between conductors and insulators, which are widely used in electronics, information, optoelectronics and other fields. Commonly used types of semiconductor materials include: Silicon (Si): It is one of the earliest semiconductor materials to be used and has a wide range of applications.
4. Semiconductor materials are widely used in electronics, optoelectronics, computer science and other fields. Here are a few commonly used semiconductor materials. Silicon (Si) Silicon is one of the most commonly used semiconductor materials, with a stable crystal structure that makes it easy to prepare and process.
