hot pressure moulding Silicon Nitride ceramic sheet plate
Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
In the current production, the injection pressure of almost all injection machines is based on the pressure (converted by the oil pressure) applied by the plunger or the top of the screw to Insulating Ceramic Substrate Sheet Electronic Plate the plastic. The role of injection pressure in injection molding is to overcome the flow resistance of the plastic from the barrel to the cavity, to give the melt filling rate and to compact the melt. The injection pressure is divided into injection pressure and holding pressure, usually 1 to 4 injection pressure + 1 to 3 holding pressure. Generally, the Insulating Ceramic Substrate Sheet Electronic Plate holding pressure is less than the injection pressure. Adjust according to the actual plastic material used to achieve the best The physical properties, appearance and size requirements. The time required to complete an injection molding process is called the molding cycle, also called the molding cycle. It Insulating Ceramic Substrate Sheet Electronic Plate actually includes the following parts: Molding cycle: Molding cycle directly affects labor productivity and equipment utilization. Therefore, in the production process, the relevant time in the molding cycle should be shortened as much as possible while ensuring the quality. In the entire molding cycle, the injection time and cooling time are the most important, they all have a decisive impact on the quality of the product. The filling time in the injection time is directly inversely proportional to the filling rate, and the filling time in production is generally about 3 to 5 seconds.
properties:
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.
