Injection molding is also called injection molding. Dalian injection molding is to send granular or powdery plastic from the hopper of the injection machine into the heated barrel. After being heated and melted into a flowing state, it is injected into the closed mold cavity through the nozzle at the front end of the barrel under the push of the plunger or screw. The molten material filled with the cavity is under pressure, After cooling and curing, the molded products are obtained by mold opening and parting.


Injection device


Main function: make the solid plastic particles plasticize evenly into a molten state, and inject the plastic melt into the closed cavity at sufficient pressure and speed.


Composition: hopper, barrel, heater, metering device, screw (or plunger) and driving device, nozzle and other components.


The main functions of the clamping device are: to realize the opening and closing action of the die; Provide enough clamping force to close the die during forming; Push out plastic products during mold opening.


Composition: mechanical and hydraulic.


Post treatment of plastic parts


Objective: to improve the performance and dimensional stability of plastic parts. ① Annealing treatment: place the plastic parts in the heating medium or oven for a period of time, and then cool them slowly to reduce or eliminate the internal stress. Temperature: 10 ~ 20 ℃ above the service temperature. ② Humidity control treatment: anneal in hot water to achieve moisture absorption balance and stabilize the color, performance and size of plastic parts. Temperature: 100 ~ 121 ℃; Time: 2 ~ 9h.


Injection molding process parameters: temperature ① barrel temperature ② nozzle temperature ③ mold temperature 2. Pressure ① plasticizing pressure (back pressure) ② injection pressure 3. Time: ① injection time ② pressure holding time ③ cooling time ④ mold opening and product taking time ⑤ mold closing time


Dalian injection molding


Characteristics of injection molding


There are many kinds of molding plastics. Injection molding can be used for almost all thermoplastic resins and most thermosetting resins;


It can form large and small parts, or complex parts;


High degree of automation of production process, low labor intensity and good working conditions;


The mold manufacturing cost is high, which is not suitable for single piece or small batch production.


Application of injection molding


It can be used in thermoplastics, thermosetting plastics, low foaming plastics, hollow plastic products, etc.
