Screw & Barrel for Blow Molding High Speed Extrusion – 75mm

High-speed extrusion screw and barrel for blow molding.
Plastic blow molding products, such as: plastic bottles, plastic cans, and plastic containers
Applicable plastics: HDPE, UHMWPE, LDPE, LLDPE, MDPE, PP, PETG
Multilayer co-extruded plastics: EVOH, EVAL, MR

Based on our experience
75mm L/D26 blow molding extrusion machine, motor configuration 55 KW, the production capacity of extruding HDPE can reach about 175kg/H.
In terms of the stability of the feeding pressure and the temperature, the operation of the blow molding extrusion screw and barrel is required to be relatively stricter.

High functional plastic containers or blow molded products have relatively high quality and functional requirements. Sometimes it needs multi-layer co-extrusion to achieve the functional requirements. In the field of multi-layer extrusion, the stability of feeding pressure and temperature, as well as the uniformity and light transmittance of product mixing are extremely high. Under this requirement, the relative degree of screw and barrel design will directly and seriously affect the extrusion quality.

The common problem of screw and barrel is that it cannot be extruded at high speed, or the temperature rises out of control during high-speed extrusion, or the output is poorly mixed during high-speed extrusion, or the short service life of the high-speed screw and barrel. These are the problems we have solved.

To help our customers improve the extrusion speed, production capacity and mixing quality, and to create greater added value for customers' extrusion machines is our goal of continuous pursuit and improvement.
