I.Equipment Overview:
ZW-703 desktop laboratory blown film machine consists of one 16 single-screw extruder, single-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, as well as less material, small footprint, etc., especially suitable for the laboratory environment, is the enterprise and universities, research institutes, research and development of new materials, new formulas, new processes, a powerful tool.
III.Primary Configuration:
|
Screw |
|||
|
Feed section longitudinal grooving, making the extrusion volume increased, while the raw material in the barrel plasticizing time is long, better plasticizing effect. Low rotational speed can reduce the wear and tear of barrel and screw, and prolong the service life. |

Features of the die head:The die head is an internal single-layer runner structure, designed for degradation material products, the mold runners are uniformly distributed, no dead ends, improving the fluidity of the melt in the mold, effectively solving the problem of material retention in the mold, so that the molded film products have a good surface finish and transparency. |
