ZL-3065 Precision Three-layer Lab Blown Film Extruders

Precision three-layer laboratory blown film machine consists of three 20 single-screw extruders, three-layer blown film die head blown film auxiliary machine and PLC centralized control system

I.Equipment Overview: 

Precision three-layer laboratory blown film machine consists of three 20 single-screw extruders, three-layer blown film die head blown film auxiliary machine and PLC centralized control system. Plastic raw material is melted and plasticized and extruded by one extruder, and then blown into film with independently adjustable width, thickness and layer ratio by sleeve type die head.

 

II.Description:

The product integrates the company’s precision extrusion technology and blown film molding technology, with convenient control and adjustment of stable performance, wide applicability of raw materials and less material, small footprint, etc., especially suitable for laboratory environments, is the enterprise and universities, research institutes, research and development of new materials, new formulas, new processes, a powerful tool.

III.Primary Configuration:

Extruder Section

Maximum blown film width

240mm

Screw

The longitudinal grooving of the feed section makes the extrusion volume increase, while the raw material is plasticized in the barrel for a long time, and the plasticizing effect is better. Low rotational speed can reduce the wear and tear of barrel and screw, prolonging the service life.
