1. Injecting a method of production of industrial products. Products usually use rubber injection and plastic injection. Injection can also be divided into injection molding molding method and die casting. Injection molding machine (referred to as injection machine or injection molding machine) is the main forming equipment of thermoplastic plastic or thermosetomic materials using plastic molding molds into various shapes of plastic products. Injection molding is achieved by injection molding machines and molds.
2. The squeezing material is heated and plasticized by squeezing out the ingredients and screws, pushing forward by the screw, and continuously made of a processing method of various section or semi -products through the head of the machine.
3. Blowing plastic is also known as hollow plastic, which is a rapidly developing plastic processing method. The thermoplastic resin is squeezed out or injecting the pipe -shaped plastic blank, while it is hot (or heated to softened state), placed in the mold opening, and the compressed air is immediately passed into the type of blank after closed molds to blow the plastic type blank blowing. Delivery is close to the inner wall of the mold, and after cooling the mold, various hollow products are obtained.
4. A plastic processing process. The main principle is to soften the plastic hard sheet of Pingzhan, which is adsorbed on the surface of the mold, cooled after cooling, and is used in a technical process in various industries.
5. Mooming molding is also known as suppressing or compressing molding. It is the operation of pink, granular or fiber plastic first in the mold cavity at the molding temperature, and then close the mold to pressurize and solidify it. Modular molding can be used for thermosetry plastic, thermoplastic plastic and rubber material.
6. Pressing the formation of the melting plasticized thermoplastic plastic through two or more parallel heterochoric rotation rotating rotating rotation gaps, so that the melt is squeezed and extended by the roller, stretching, and becoming a continuous chin with certain specifications and meet the quality requirements Products, finally by natural cooling and molding. The pressure extension process is often used in the production of plastic film or sheets.
7. Foam forming is the process of adding appropriate foaming agents to foaming materials (PVC, PE, PS, etc.) to make the plastic produce a microporous structure. Almost all thermosetry and thermoplastic plastic can be made into foam plastics, and foaming has become an important area in plastic processing.
8. Winding molding process is to wrap the continuous fiber (or cloth band, pre -immersed yarn) soaked in the resin glue in accordance with a certain regularly, and then solidify and remove the products.
9. Layer pressure molding refers to the combination of multi -layer or different materials under heating and pressure. Commonly used for plastic processing and rubber processing.
10. Watering molding is a method of plastic processing. Early casting was to see the polymer into the mold into the mold under normal pressure. In the 1960s, the nylon single casting seeing the development of polyamide with the development of molding technology, the traditional casting concepts have changed. The polymer solution, decentralized polyvinyl chloride paste paste and melt can also be used for casting molding.
11. Drop plasticity is the characteristic of the use of thermoplastic polymer material, that is, under certain conditions, it has adhesive, and the characteristics of solid state can be restored at room temperature. It is shaped into a design form according to its sticky state, and then solidified at room temperature.
12. The compression molding method is mainly used for the production of thermosetry plastic products. After the molding is heated, it melts, press the mold, and then solidified through heating.
13. Resin transmission molding is a process method of infiltrating the resin into the closed mold and solidifying the material and solidifying. This technology can effectively reduce equipment costs and molding costs without pre -immersion and hot pressure tanks. In recent years, this technology has developed rapidly. It has been widely used in the fields of aircraft industry, automobile industry, and ship industry. It has studied the development of various branches such as RFI, VARTM, SCRIMP, and Sprint to meet the application needs of different fields.
14. The squeezing is to press the blanking material placed in the concave mold with the punch or convex mold to cause a plastic flow, so as to obtain a pressure processing method of the molded pore or bump shape of the mold. During squeezing, the gray material produces three -way compression stress, and even a low -plastic gray can be squeezed and shaped.
15. Thermal formation is a special plastic processing method that processs thermoplastic plastic sheet into various products. Processing thermoplastic plastic sheet into a special plastic processing method of various products. The sheet is heated on the frame to softened. Under the action of external forces, it is close to the mold of the mold to obtain the shape of the same surface. After cooling, it will become a product after repair.
16. Hand paste is also known as hand -mounted and forming and forming. It refers to hand -made operations on the mold that is applied to the mold. CICF and release of this process of plastic products.
17. Laserrapidprototyping is a new manufacturing technology that integrates CAD, CAM, CNC, laser, precision servo, and new materials. Compared with the traditional manufacturing method, it has: the prototype and high interchangeability; the manufacturing process has nothing to do with the geometric shape of the manufacturing prototype; the processing cycle is short and the cost is low, the general manufacturing cost is reduced by 50%, the processing cycle is shortened by more than 70%; the height is height Technology integration, realize design and manufacturing integration.
18. Melving deposition forming method (FDM, Fuse DEPOSITION MODELING). This process is to squeeze out of the heating nozzle of the heated nozzle, such as the filament plastic plastic, wax, or metal melting of the silk material, according to the predetermined trajectory of each layer of the part to The fixed rate is fixed for melt deposits.
19. CNC computer digital control machine tool is an automated machine tool equipped with a program control system. The control system can logically handle programs with control codes or other symbols, and use the decoding to make machine tool movements and processing parts.
20, 3D printing (3DP) is a type of rapid molding technology. It is a technology based on digital model files, using powder -shaped metal or plastics, etc., and constructing objects to construct objects by layer -by -layer printing. 3D printing is usually implemented with digital technology material printers. It is often used in the fields of mold manufacturing, industrial design and other fields, and is gradually used for direct manufacturing of some products. It has already been used by this technology.
