Collin Lab & Pilot Solutions GmbH of Maitenbeth, Germany, highlighted extrusion-related systems at K 2019 — including a blown film line with calendaring as an inline system for extrusion, featuring camera inspection.
“These actually independent systems for blown film and flat film production are interconnected inline and this, new film systems are possible,” said Collin CEO Friedrich Kastner.
Kastner said the production lines enable new packaging products to be made in more sustainable way without abandoning the performance of multi-layer film systems. “The main advantage is that with this line, we can produce films with highly precise layers,” he said.
Customers can use the line for standard polymers and bio-resin, as well as post-industrial and post-consumer material.
Also at K 2019, Collin showed further developments for the Teach Line series of table-top machines that include compounders, extruders, blown and flat film lines, plus roll mills or pelletizers. The second-generation Teach Line has a completely digital operation and control, and a seven-inch touch display. All parameters can be controlled and evaluated online.
Collin also showed a new medical catheter tubing line for micro-extrusion. The outer diameter of the tubing stand was half a millimeter.
The company presented a roll mill with camera inspection, and extrusion slot-dies with accessories in a wider range.
Sister company BritAS Recycling-Anlagen GmbH of Hanau, Germany, launched a series of piston screen changers at K 2019 — the CMF (continuous piston screen changer) and DMFD (discontinuous bolts screen changer).
“We are expanding our product range and serving customers who want to recycle waste plastics with less pollution,” said Kastner, who is managing chairman and managing partner of BritAS.
The new screen changers complete the portfolio of ABMF, ABMF 1600 and ABMF PET. BritAS filters are mainly used in post-consumer recycled plastics applications and for recycling agricultural film waste, post-industrial waste and at compounders.
The company increased the filter surface by 50 percent on the ABMF 1600.
