The polyamide thermal breaks extrusion line is special equipment used to produce nylon insulation strips (PA66+GF25) for building doors and windows. Its core process is to extrude the mixed raw materials through high-temperature melting. The main equipment of the The polyamide thermal breaks production line includes: twin-screw extruder, mold system, cooling water tank, haul-off unit, and automatic cutting machine.
When the polyamide thermal breaks production line is running, the pre-dried nylon glass fiber particles are plasticized by the extruder and formed into a “C” or “I” type composite structure blank through a multi-cavity precision mold, and then enter the gradient cooling water tank to eliminate internal stress and solidify. The traction system maintains a stable line speed (usually 15-30m/min) through servo control, and the end is equipped with a flying saw or laser cutting to achieve precise slitting. The key control points include melt temperature (240-280℃), vacuum shaping negative pressure (0.06-0.1MPa) and cooling water temperature difference (segmented control within ±2℃) to ensure the product’s mechanical strength (≥24MPa) and dimensional accuracy (±0.1mm).
Polyamide thermal breaks are mainly used in thermally insulated aluminum profiles for building doors, windows and curtain walls. Their core function is to block the heat conduction of the metal frame and improve the thermal insulation performance of the overall structure. The polyamide thermal breaks are also used in refrigeration equipment, rail transit vehicles (such as high-speed rail window frames) and solar panels.
