Product category: Compounding lines

Compounding lines

In order to satisfy the latest market trends, COMAC proposes high flexibility extruding lines able to produce a wide range of high added value compounds even in small-medium size lots.

The process is managed by a last generation PLC software developed by Comac, which allows complete control of production parameters.

Some examples of production include:
  • Mineral filled compounds with up to 80% filler contents
  • Glass fibres, glass beads, mixed fillers
  • Flame retardants

Masterbatch lines

Optimized for the strict quality requirements of masterbatch producers, these lines are fitted with the most advanced solutions coming from 40 years of real experience in this field.

A high shear-rate and an extremely performing screw geometry enable to achieve high pigment concentrations in different polymer carriers with optimal dispersions.

A compenetration ratio of the screws up to ≅ 1.65 conjugates excellent quality with excellent production capacity.

Self-cleaning screw profiles avoid prolonged production stops. Strand extrusion die heads are typically used on color/additive masterbatch and on compounding lines for some applications (e.g. glass fiber compounds). Screen changer and extrusion head are designed for quick opening and fast colour change. A control panel and automatic devices allow operators to manage production with minimum effort.

Extruders for special applications - PET WASTE REPROCESSING

Our know how on PET waste reprocessing is focused on plants for production of regenerated granules for injection moulding and other applications, but, also on integrate solutions for direct recycling into products.

By proper design of extruders (screw geometry, degassing systems, etc.) de-polymerization can be dramatically limited or avoided; we, Comac, could develop highly-performing and reliable dryerless solutions for PET waste extrusion applied in cooperation with major manufacturers of downstream line sections.

About us

Company details

From 40 years, COMAC has specialized in the design, engineering and production of extruders for the plastics industry.

We want to be considered a partner and not just a supplier; together with our customers we develop ad hoc solutions, designed to meet specific needs of a constantly evolving market.

In a context of increasing globalization, we continue to propose, as our strength, a vertically integrated production and constant support to our customers; certain that the "service" is a fundamental asset of our company.
