Extrusion

Extrusion Solutions

Highly accurate and stable drying, conveying, dosing & mixing systems for both mono and co-extrusion lines


Process description

Plastic extrusion is a continuous, multi-stage process for the production of thermoplastic parts with a fixed cross-sectional profile.

Typical end products

High volume end-consumer products. For example: films, cable coatings, pipes and tubes. It is a part manufacturing process and is not based on lot sizes i.e. weight.

Process

The raw material is fed into a heated barrel; either a single or a twin screw will mix the plastic and force it through a die. The number of single to twin screws in use today is approximately at a ratio of 80/20.

Typical materials being processed

Most granular raw and compounded polymers, including some elastomers. In addition regrind materials and additives.

Description of motan system/equipment used

Highly accurate and stable drying, conveying, dosing & mixing systems for both mono and co-extrusion lines.

Typical dosing & mixing units:

Volumetric dosing & mixing units (SPECTROCOLOR V) as well as gain-in-weight blenders (GRAVICOLOR, ULTRABLEND) or simple loss-in-weight dosing & mixing units (SPECTROCOLOR G).
