PE Foam Pipe Machine – High-Performance Extrusion Line for Insulation Pipe, Foam Tube & Backer Rod Production

The PE/EPE foam pipe machine series is a high-efficiency extrusion system designed for producing a full range of PE foam tubes, insulation pipes, foam rods, backer rods and foam profiles. Using a high L/D single-screw extruder and an advanced physical foaming process, the line ensures stable foaming, uniform cell structure, accurate diameter control and consistent product density, even during long-time continuous operation.

Our production lines are widely used in industries such as construction insulation, air-conditioning and plumbing systems, building joint sealing, sports and toy manufacturing, furniture packaging and protective cushioning. With flexible mold designs, the same line can quickly switch between different pipe diameters and rod sizes, making it ideal for manufacturers requiring multi-specification foam production.

Broad Range of Products You Can Produce

Depending on the mold configuration and application requirements, the machine can manufacture:

 PE/EPE foam insulation pipes for HVAC and hot-water systems

 Foam backer rods for expansion joint sealing and construction gaps

 Solid and hollow foam rods in various diameters

 Pool noodles and sports foam tubes

 Toy foam pipes and safety protection tubes

 Packaging protection foam profiles for glass, furniture and hardware

 Custom foam shapes & profiles through tailored mold design

The foam products feature excellent thermal insulation, moisture resistance, high rebound, lightweight structure, cushioning performance, flexibility and are widely used as environmentally friendly alternatives to traditional insulation and packaging materials.

 

Technical Highlights of the PE Foam Pipe Extrusion Line

Our PE foam pipe machines combine advanced control technology with robust mechanical design to deliver long-term stable performance.
