Injection moulding of the highest precision:

 

The raw material

The initial material for the production of our plastic containers is the granulate. This is small plastic pellets to which colour is often added. The granulate is stored in large silos. From there it is transported through feeder pipes to the injection moulding machine.

 

The machine

An essential component of the machine is a cylinder, inside which a “corkscrew thread” moves. In it the granules are transported to a nozzle, in front of which the injection moulding tool is clamped into the machine. The small plastic pellets are heated, ground up and mixed, giving a viscous compound.

 

The production

Two plunges press the two halves of the mould together and the liquid plastic can be injected into the cavities of the moulding tool. The tool then moves apart, the finished container is taken out and the process is repeated.

The framework

An injection moulding machine requires enormous closing force to hold the two halves of the tool together.

 

1. Injection process prepared

Tool open, granulate stocked.

2. Injection process starts

Tool closed, granulate proceeds into the spiral.

3. Injection process

Tool closed, granulate heated and as a viscous plastic material injected through a jet into the cavities of the tool.

4. Injection process completed

Container cools off.

5. Injection process finished

Tool moves apart, container removed via robot.
