PY Series Injection Moulding Machine

PY series injection moulding machine adopts the latest technology, fully servo motor drive, energy saving and high efficiency, fast and precise operation. It will effectively improve product quality. The equipment responds quickly and has a low failure rate. It can be applied to the injection molding production of different plastic products.

 

  • Detail Introduction

1. Brief introduction:

In terms of injection moulding structure, PACKER injection moulding machine adopts screw-plunger hybrid structure and PID temperature control method, which effectively guarantees the stability of plasticization and metering. From general-purpose resins to engineering plastics, high-quality injection molding can be carried out, which is suitable for the production of micro-small precision injection moulding parts in various fields such as microelectronics products, communications, electrical appliances, instruments, meters, automation devices, clocks, toys and medical equipment. .

 

2. Working principle of injection moulding machine.

The injection molding machine is a process in which the plasticized molten state (viscous fluid state) plastic is injected into the closed mold cavity with the help of the thrust of the screw (or plunger), and the product is obtained after curing and shaping. Injection molding is a cyclic process, each cycle mainly includes: quantitative feeding—melt plasticization—pressure injection—mold filling and cooling—mold opening and pick-up. After taking out the plastic products, the mold is closed again, and the next cycle is carried out.

 

3. Work flow of injection molding machine.

The granular or powdered plastic is feed into the hopper. Heating the outer wall of the hopper through spiral rotation to melt the plastic. Injection moulding machine closes the mold and moves the injection seat forward to fit the injection port. The pressure oil is injected into the injection cylinder and the screw moves forward. After cooling for a certain period of time under pressure, the mold can be opened to take out the product. The purpose of keeping the pressure is to prevent the melt from flowing back in the mold cavity, supplement the material in the mold cavity, and ensure that the product has a certain density and dimensional tolerance.

 

4. Advantages of PACKER injection molding machines.

A, Swiveling And Two Layers Linear Guide Rails Injection Unit
· Swiveling designed injection unit helps change screw and barrel to be much easier
· Two layers linear guide rails helps shorten the length of injection unit support device, less deformation of the support device, which helps to improve the injection precision
· One piece type injection unit support device, helps injection movement to be more precise
· Dual carriage cylinder with diagonal layout helps to get more operation space, and get more precise injection movement.

B, Wider Space Between Tie-bars Clamping Unit
· Wider range space between tie-bars, more molds size available and able to meet the needs for automatic mold installation system
· Long and wider designed movable platen moving feet ensure stable mold open and close movement
· Graphite cooper bushes, bigger diameter tie-bars, high quality material for tie-bars and toggle pins ensure longer life-span
· T-slot with screw hole platen, mold installation faster and more flexible
· Ejector with adjustable stroke, meets more special ejector movements

C, Controller Options to satisfy customer's request
· You can choose Techmation, KEBA,B&R, ETC
· Choose traditional button screen or touching screen

D, Excellent Hydraulic system
· We choose best brands to cooperate, the great experience and excellent hardware ensure our hydraulic system to be more stable and precise
· Valves Layout nearby the cylinders, ensure a faster response and precise hydraulic system

E, Energy Saving Servo System
· Equipped with precise and energy saving servo motor system, energy saving capacity can reach to 30%~75% than traditional IMM
· High response servo motor, more than 90% working efficiency
