Servo Energy Saving Injection Molding Machine Screw Barrel

Product Introduction:

Servo energy-saving injection molding machine series models are equipped with high performance servo drive control system, high performance synchronous motor, compared with the traditional injection molding machine repetition accuracy is better, faster response, can save 20%-80% of electricity, for the rear wall, high precision products, the effect is more significant. Injection molding machine is by means of the screw (or plunger) thrust, the plasticized molten state (i.e., viscous flow state) material is injected into the closed mold cavity in a high pressure fast way, and the product is obtained after cooling and curing. In this process, there are die locking, shooting glue, pressure preservation, storage, cooling, mold opening and other procedures. The traditional injection molding machine oil pump motor determines the power according to the highest pressure and flow, and determines the constant flow at a fixed speed. The excess hydraulic oil returns through the relief valve, wasting energy. After the servo transformation of the injection molding machine, the pressure and flow double closed-loop computer control is adopted. The flow and pressure can be output according to demand in the stage of mold locking, pressure maintaining and cooling, but the motor is low speed or stop, and the power consumption is minimal. Due to the large load of induction motor, the idle work is large and the leading power consumption is large. In contrast, the servo motor is a permanent magnet synchronous motor with high efficiency and power factors. Under the average condition of injection molding machine, the efficiency of the servo motor is 10% higher than that of the asynchronous motor. Due to the high pressure throttling of the traditional injection molding machine, the oil temperature rises, leading to the thinning of the oil body, softening of the pipeline and oil leakage, so the hydraulic oil must be cooled. The servo system adopts gear pump to provide flow according to demand. There is no throttling and low temperature rise of hydraulic oil.

Servo energy saving injection molding machine screw barrel manufactured by our company is made of high quality alloy steel 38CrMoAlA, after modulation, molding, qualitative, nitriding, (or spray welding double alloy) fine grinding, polishing and other processes refined, with very high precision, wear resistance and long life, for many famous injection molding machines. Can be customized according to customer needs, with large extrusion capacity, low energy consumption, good self-cleaning ability, high length-diameter ratio of screw very good to reduce the molecular viscosity of plastic polyester, to solve the problem of input and output ratio is unreasonable.

Scope of application:

Daily necessities, toys, electrical parts, mechanical parts, textile, auto parts, chemical, medical instruments, construction, electronic parts and other industries.
