Stainless Steel Extruding Tools for PA66 Plastic Nylon Thermal Break Strips Polyamide Profile
Our mold solutions are engineered to meet precise market and customer requirements. We specialize in high-stability, high-yield, and high-adaptability automatic extrusion production lines for nylon insulation strips.
Extrusion molding (plastification extruding) is a critical process where molten substance is pushed through a mold under high pressure to achieve the final product form. The mold determines the exact shape and dimensional accuracy of the profiles. These thermal insulating strips are widely applied to aluminum doors, windows, and curtain walls.

PA66 granules and fiberglass are dried and fed into the barrel through a hopper. The rotation of the screw forces the material into the spiral groove die direction. Due to the tight screw barrel gap, the material is pressurized and plasticized into a nylon thermosol via high-temperature electric heating rings.




Each mold is securely placed in a plywood case to ensure safety throughout the transport process. The typical weight of a mold ranges from 60kg to 100kg, depending on the dimensions. Our standard production cycle is 28-35 working days, followed by comprehensive mold testing to verify that both the tool and the resulting polyamide strips meet all quality standards.
