Silicon Nitride Ceramic:
Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment for making thermoplastic or thermosetting plastics into various shapes of plastic products using plastic molding dies. Divided into vertical, horizontal and all-electric. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it shoot out and fill the mold cavity. Injection molding machines are also known as injection molding machines or injection machines. Many factories are called beer machines, and injection products are called beer parts. It is the main molding equipment for making thermoplastic or thermosetting materials into various shapes of plastic products using plastic molding molds. According to the arrangement of the injection device and the clamping device, the injection molding machine can be divided into vertical, horizontal and vertical-horizontal composite. The role of the injection system: the injection system is one of the most important components of the injection molding machine, generally including plunger type, screw type, screw pre-plastic plunger injection High Precision Scribing Ceramic Substrate Sheet Thin Plate High Precision Scribing Ceramic Substrate Sheet Thin Plate
Three main forms of shooting. The most widely used is the screw type. Its function is that in a cycle of the plastic injection machine, a certain amount of plastic can be heated and plasticized within a specified time, and the molten plastic can be injected into the mold cavity through a screw under a certain pressure and speed. After the injection, the molten material injected into the cavity is kept in shape.
Composition of the injection system: The injection system consists of a plasticizing device and a power transmission device.
The plasticizing device of the screw injection molding machine is mainly composed of a feeding device, a barrel, a screw, a rubber component, and a nozzle. The power transmission device includes an injection cylinder, an injection seat moving cylinder, and a screw drive device (melting motor) High Precision Scribing Ceramic Substrate Sheet Thin Plate.
The role of the clamping system: the role of the clamping system is to ensure that the mold is closed, opened and ejected. At the same time, after the mold is closed, sufficient clamping force is supplied to the mold to resist the cavity pressure generated by the molten plastic entering the mold cavity, and prevent the mold from opening seams, resulting in a bad status of the product.
The composition of the mold clamping system: the mold clamping system is mainly composed of a mold clamping device, a machine twisting, a mold adjusting mechanism, an ejection mechanism, a front and rear fixed template, a movable template, a mold clamping cylinder and a safety protection mechanism.
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.
