Product Introduction

The one-step PERT insulation pipe production line cannot meet the production requirements using ordinary extrusion equipment, and the screw and barrel of the extruder, pipe mold, and sizing cooling system must be specially designed. Huashida Company overcame 130 technical difficulties in 2 years and became a one-step PERT insulation pipe production line with independent intellectual property rights!

Extrusion Machine

Using a single screw extruder, the extrusion section adopts a forced water-cooled feeding section, the barrel is slotted, and the power consumption of the main drive motor is significantly reduced; The screw with a large aspect ratio (25-38:1) has excellent plasticizing effect.

Extruder head

Professional PERT pipe mold, with smooth inner and outer surfaces, uniform wall thickness, and special treatment of the flow channel for greater wear resistance. PERT pipe specialized head.

Vacuum sizing box

Unique designed sizing sleeve, all stainless steel vacuum box, using PERT pipe specific sizing sleeve, accurate sizing, good effect; Spray cooling ensures the quality of the pipes.

Wrap the machine head

The patented vacuum coating mold and specially designed coating head ensure uniform thickness of the coating layer.

Winding machine

Patented fiber reinforced equipment, fiber weaving, ensures the strength of pipes.

Chipless cutting machine

Large range cutting of 32-200mm; High strength alloy steel blade, rotary cutting, smooth and even pipe cutting, with small errors; Cutting follow-up ensures precise cutting position; Professional PLC control, accurate action; The cutting position is specially designed to ensure that the cutting is completed in one go.
