Silicon Nitride Ceramic:
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. 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.
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.

SHENZHEN HARD PRECISION CERAMIC CO.,LTD
Shenzhen Hard precision ceramics Co., LTD. has been committed to design, development and manufacture of industrial ceramic products since 2007. Compared with metal, advanced ceramic has the following excellent performance: high hardness, high strength, high temperature (fire), and can wear resistance, corrosion resistance, acid and alkali resistance, oxidation resistance, insulation, non-magnetic and good chemical stability . So it is often used in the environment where the metal material cannot endure. With its promising application , advanced ceramics are widely used in aerospace, aviation, military industry, nuclear power, machinery, textile, chemical, electronics, food, medical and other industries. Our advanced ceramic products made by zirconia (ZrO2), alumina (Al2O3), silicon nitride (Si3N4), etc. Our products can divide into two parts: one part is ceramic ball, rods, tubes, ceramic materials such as plate, block, strip and so on, and the other part is the precision ceramic parts which are for industrial use and civilian products. Our company has advanced one-stop equipment and technology of ceramic forming, sintering and processing. Hope we can establish excellent cooperation with customers from at home and abroad for a wide range .
