The most important step in the heading process is the production of the dose of polymerized granulates so that a correctly formed high quality shoulder component can be produced.

Aisa has developed the volumetric dosing system to obtain the most precise dose possible.

The result is impressive:

• Constant shoulder weight > No more volume variations.
• A melt temperature reduction of 18% > Less cooling needed after compression moulding.
• Improved quality of shoulder and surface > Reduced flow-lines and melt fracture defects.
• Optimized colour change (downtime less than 10 minutes) > Reduced material wastage.
