2 Layers Blow Molding

The Labtech co-extrusion blow molding machine is a compact unit with a pleasing modern design finished off to the usual high standards that Labtech applies to all of its plastics and rubber machines. An attractive feature of the lab blow molding unit is its “futuristic” swing-up front door that allows maximum unobstructed space for access to the working parts of the machine. The blow molding unit itself is portable and in intended for use with Labtech Single Screw Extruders, although on request, the machine can be modified to fit most other brands of extruder in the 20 to 30 mm diameter range.Designed primarily as a laboratory machine the co-extrusion blow molding machine is ideal for making small bottles (up to approximately 400 cc) for color assessment purposes, product development and prototyping.
