Injkon is a complete proven reliable control system for injection molding machine.

Injection moulding machine setting pdf. System consists of three units. Each core is controlled separately. Injection time filling time pressure keeping time gate sealing time gate sealing time is the time when resin stops flowing by solidification at the gate part. The particle is the unit of fed into a heated barrel mixed using helically shaped.

Setting will differ by the molding machine but basically should be considered as below. A typical single stage screw consists of three regions. Injection pressure should be kept high enough in order to ensure that the pressure value does not drop below the required set point values during the entire cycle. Injection molding machine core setting screen depending on your setup your machine may be equipped with up to 3 cores a b and c.

Optional transformer 1 operating panel. Since the cores are freely. The easiest way to do the set up on the injection moulding machine is based on the machine set up operator or technician s. 12 9 2012 10 injection unit screw to transport and melt the polymer.
