injection moulding machine

Injection moulding machine Hissoncompany is a professional injection molding machine maker inNingbo China. Fordifferent material,we have two different types of injection molding machine, HI-G series is the general purpose type,which are available to injection molding of various thermoplastics such as PC, PP, PE, Nylon, A.B.S.PET.PVC etc.to produce all kinds of medium-or small-size plastic articles and daily-use commodities;and our HI-P is specially designed for PET preform injection. The working principle of injection molding machine: After being heated and plasticized in the barrel, the material will be injected into the mold, the final products will be formed after cooling. Along with the developing of modern industry, the new plastic material’s application scope, because of material’s durability, light, low cost, shiny characteristics, becomes wider and wider, including the containers, household appliances, medical, sports field and so on. Hisson injection molding machine is the type of fully-automatic machine, being provided with high efficiency, high reliability, high speed, low noise, low power consumption and other advantages. A ) Main Features Adopted imported computer special designed for injection molding machine, different languages are optional, liquid crystal colorful screen, digital memory for mould group, cycle dynamic display on screen, alarm function. Plasticizing screw is made of Nitrided steel alloy, with strong durability, nice erosion protecting ability and lone using life. Hydraulic system has equipped with world famous oil pump, proportational pressing valve and oil flow controlling valve to get high precision action, pressure and flow adjusting can be controlled in digit. Double proportional pressure-flow hydraulic system with low noise, low power consumption and stable running characteristics. Mold platen is made of graphite cast iron, and tooled in high precision numerical equipment, with high solidity and durability. Adopted trunk type combined platen to ensure higher action precision. Stretch bar, guide bar, mold closing piston bar and injection piston bar are made of high grade steel fit to strong pull, and hard chrome will be plated on the surface. Five-point double-toggle mould locking Oil motor is to actuate the gear wheel for mold position adjusting, each stretch bar will get equal force, easy and safe to operate. Central hydraulic ejector system, you can adjust the ejecting stroke through the approaching switch during the stroke scope, also you can set as several times ejector or vibration ejector according to particular condition. Injection parts is actuated by stepless high torque oil motor for pre-plasticizing. Double cylinder balance injection. Four stages injection and three stages pressure holding. Precision temperature controlling system, resistance heating ring is used for heating barrel, equipped with automatic temperature controller or controlled by PID system in computer, heating is fastly and equally. High precision potentiometers, three famous brand potentiometers are used for controlling injection, mold moving and ejection respectively, the precision can reach +/-0.1mm. Storage type automatic grease lubrication system. Various operation methods: Spot, Manual, Semi-auto and fully-automatic types. Mechanical and pneumatic safety protection device, the mold closing will not be done until closing the safety door.
