What is plastic moulds for PA profile extrusion line?
PA profile means polyamide thermal break strips. Which is one of the most common materials used for years to create thermal breaks in curtain walls, commercial windows, doors, and more. It is a reinforced polyamide strip, which occurs as a non-metallic, composite, structural material, and is installed between the interior and exterior profiles of the windows that forms an insulating barrier between the two.

The shape, size and output of polyamide strips are determined by plastic moulds. Therefore, plastic mould is a very important and indispensable part of the polyamide strips extrusion line.


Plastic injection molding is the most commonly used method for making plastic products. Injection molding is a method in which molten plastic usually a thermoplastic is poured into a metal mold composed of steel or aluminum. Once the molten material has been put into the mold, it must be allowed to cool until it solidifies before the final item can be extracted. Molding materials including ABS, acetal, nylon 66, low-density polyethylene (LDPE), high-density polyethylene (HDPE), polycarbonate, polypropylene, polystyrene and thermoplastic elastomer are used. Plastic injection molding is used in a variety of industries including construction, food and beverage, medical and pharmaceutical.

Our company mainly manufactures molds for nylon 66 products.
