Services

Brixia Plast provides its customers with a comprehensive service that can meet all their needs: from cleaning, to disassembly of plasticizing units, to dimensional checks preceding any overhaul.

Screw revisions

A screw can be overhauled to new condition by helical welding and subsequent polishing, heat treatment and grinding. However, it is necessary that the screw core be in good condition, as the same is not serviceable. Based on the type of polymer processed, welds with different abrasion and corrosion resistances are recommended, both on screws with nitrided and hardened material.

Cylinder overhauls

If the wear is only present at the end (in the tip valve travel area), a overhaul through the tacking. This solution, quick and cheap, allows you to  Maintain the nominal diameter of the cylinder.

Where wear is constant along the cylinder, a revision by proceeding to enlarge the diameter. This solution should obviously be combined with a vine revision (which must necessarily be welded to a diameter consistent with that of the enlarged cylinder), and to the provision of a ferrule appropriate to the new diameter.

Services

The staff and complete equipment in the service department mean that any laminating unit can be disassembled quickly.

A state-of-the-art pyrolytic oven enables the components of the plasticizing unit to be cleaned of plastic residues while complying with the most advanced environmental regulations.

Comprehensive inspections are carried out on customer components to check wear and tear and detect any problems. These checks can also be carried out at customers' premises by qualified personnel.

The overhaul of laminating units meets needs for cost containment and speed, but at the same time requires solutions that can guarantee optimal performance.
