1, open gear is a gear with hard rolling equipment will be aluminum parts out of gear wear to insulation. The purpose is to improve the shear strength of the combined profile by increasing the roughness of the profile. According to the needs of the production, the two parts of the profile should be open gear processing.
2, wearing the article is to put on the thermal insulation material, the two parts of the internal and external parts, for the next step to prepare the rolling.
3, the rolling process is divided into pre orientation and clamping, clamping, main straightening (horizontal and vertical) three step, is the key to ensure the product section tightness and perpendicularity. Composite aluminum and heat insulation strips into one body
