Foaming Extruder
This foaming extruder is a high-efficiency device specifically designed for producing foam materials. Through precise extrusion processes, it mixes plastic raw materials with foaming agents to create lightweight, high-strength foam products with excellent thermal insulation and soundproofing properties. The equipment is widely used in construction, packaging, automotive, and electronics industries for manufacturing various foamed pipes, sheets, profiles, and more. By controlling temperature, pressure, and foaming agent ratios, the extruder ensures uniform foaming effects and stable product quality. Common foam materials include polystyrene (PS), polyurethane (PU), and polyethylene (PE), which exhibit outstanding thermal insulation, shock absorption, and noise reduction characteristics. These materials are extensively applied in insulation pipes, packaging materials, automotive interiors, and building walls. With its efficient and eco-friendly production, the foaming extruder has become indispensable in modern manufacturing, meeting the growing demand for lightweight, high-performance products.

Product Introduction
Technical Background
The foaming extruder is a core device in polymer material processing, primarily used to produce lightweight closed-cell or open-cell foam plastics (e.g., XPS insulation boards, EVA foam). Its technology relies on injecting physical or chemical foaming agents into a polymer melt under high-pressure extrusion. Through screw shearing and mixing, a homogeneous system is formed. When the die pressure drops abruptly, the foaming agent vaporizes and expands, creating a honeycomb-like pore structure. Recent innovations focus on high foaming ratios and pore uniformity, utilizing two-stage screw designs with dynamic mixing elements to optimize melt homogenization. Multi-stage vacuum degassing systems precisely control foaming agent concentration. Temperature field regulation (±1°C accuracy) and die flow simulation technologies significantly enhance dimensional stability. With stricter environmental regulations, supercritical CO₂ foaming is replacing traditional fluorocarbon agents, reducing carbon emissions while enabling microcellular foaming (pore diameter <50μm). Intelligent control systems integrate melt pressure sensors and adaptive algorithms to adjust screw speed and foaming agent injection in real time, meeting stringent demands in insulation and automotive lightweighting applications.
Structural Composition
Extruder:
- Screw and Barrel: The screw is responsible for plasticizing and extruding plastic raw materials. The barrel is usually made of high – temperature – resistant materials to withstand high – temperature and high – pressure environments.
- Motor: Drives the screw to rotate and provides the required power.
- Heating Device: Multi – stage heaters provide the required temperature control to ensure effective plasticization of plastics.
- Mold: A mold customized according to the pipe specifications is responsible for shaping the molten plastic into a pipe. The mold design affects the diameter and wall thickness of the pipe.
