Our Factory Advantage
1,3D finish machining of PIR
3D-type PIR products are processed by 3D printer. The 3D printer for PIR, developed by our company, is specially used for the production of integral 3D arc plate, integral elbow, tee, valve and other special-shaped products.
2,Strict quality inspection
Each batch of products must pass the laboratory self-inspection before leaving the factory. For type inspection products will be sent to a third-party inspection institution for testing.
3,Advanced production technology
In order to mix the foaming material evenly, the factory adopts the leading high temperature foaming process. In order to ensure the dimensional accuracy, the production adopts CNC cutting.
