Silicon Nitride Ceramics:
Extrusion, also known as extrusion molding, is a method of using an extruder (extruder) to continuously pass heated resin through a mold to extrude products of the desired shape. Designed to perform well in extrusion applications, silicon nitride ceramic pins offer exceptional wear resistance and thermal stability, ensuring continuous, high-performance extrusion molding. With Silicon Nitride Ceramic Location Pins, you can expect unparalleled durability and accuracy, facilitating seamless extrusion operations and achieving consistent product quality. Extrusion is sometimes also used in the molding of thermoset plastics and can be used in the molding of foam plastics. The advantage of extrusion is that products of various shapes can be extruded, the production efficiency is high, and it can be automated and continuous production; the disadvantage is that thermosetting plastics cannot be processed by this method widely, and the product size is prone to deviation. Injection molding is also called injection molding. Injection molding is a method of using an injection molding machine (or injection machine) to inject thermoplastic melt into a mold under high pressure, and then cool and solidify to obtain a product. Injection molding can also be used for the molding of thermosetting plastics and foam plastics. The advantages of injection molding are fast production speed, high efficiency, automatic operation, and the ability to form parts with complex shapes, which is especially suitable for mass production. The disadvantage is that the cost of equipment and molds is high, and it is difficult to clean the injection molding machine. Blow molding is also called hollow blow molding or hollow molding. Blow molding is a method in which the hot resin parison closed in the mold is blown into hollow products by the pressure of compressed air. Blow molding includes two methods: blow molding and blow molding hollow products. The blow molding method can be used to produce film products, various bottles, barrels, pots, and children's toys. Calendering is to process the resin and various additives through the gap between two or more calender rolls of the calender, which turn in opposite directions, after the expected treatment (kneading, filtration, etc.) into a film or sheet, and then peel it off from the calender roll. , A molding method that is cooled and shaped. Calendering is a molding method mainly used for polyvinyl chloride resin, which can produce films, sheets, plates, artificial leather, floor tiles and other products.
