How to prevent plastic melt from rupture during plastic injection molding?

  When the melt is injected into a cavity with a large volume under high-speed and high-pressure conditions, melt fracture is very easy to occur. At this time, the surface of the melt appears transverse fracture, and the fracture area is roughly mixed on the surface of the plastic part to form a paste spot. Especially when a small amount of melt is directly injected into the cavity that is prone to be too large, the melt fracture will be more serious, and the paste spot will be larger. The nature of melt fracture is caused by the elastic behavior of the polymer melt. When the melt flows in the barrel, the melt near the barrel is rubbed by the barrel wall, and the negative force is large, and the flow speed of the melt Smaller, once the melt is injected from the nozzle, the negative force acting on the tube wall disappears, and the flow rate of the melt in the middle of the barrel is extremely high. The melt at the barrel wall is carried by the melt at the center and accelerated. Th...

The polishing treatment methods for alumina ceramics

  It has become very common for thick film integrated circuits to use   alumina ceramics . Ceramic materials mainly made of alumina (Al2O3) have good conductivity, mechanical strength and high temperature resistance. It is a widely used ceramic at present. ​ However, after the alumina ceramic is sintered and cooled, it does not mean the end of product processing. Some products do not meet the application requirements. Therefore, they need to be processed, such as size correction and polishing. The polishing treatment method of alumina ceramics is as follows: 1. Using laser processing and ultrasonic processing for grinding and polishing. 2. Use Al2O3 powder or diamond paste for grinding and polishing. 3. The method of glazing is required (suitable for products that require high surface smoothness). 4. Use diamond, silicon carbide, etc. harder than alumina to grind step by step from coarse to fine. 5. The surface of the material is processed by ion implantation. Ion implantation...

How to judge the quality of aluminum housing?

  The aluminum profile industry has become a very mature industry. The aluminum density is only 2.7g/cm. Although it is soft, it can be made into duralumin, hard aluminum, rust-proof aluminum, cast aluminum and other aluminum alloys. Nowadays, the application of aluminum housing is very extensive, let us see how to judge the quality of aluminum housing? 1. The text on the surface of the aluminum shell material is generally printed with imported inkjet codes. The text is clear, and the trademark identification, manufacturer, address, telephone, etc. are generally clearly marked. The text on the surface of the real fake aluminum veneer material is mostly printed by ordinary printing machines. Blur, its manufacturer, display etc. 2. The aluminum outer packaging material is made of high-quality raw materials, with high technical precision, and the surface and inner layers feel smooth and even. 3. The wall thickness of the aluminum shell is uniform, the aluminum veneer material is tight...
