Our concrete spun pile mould has the following characters: 1. The cylinder of pile moulds is made to order according to different piles, the longest cylinder is 6m with less welding seam and reduce influence of welding distortion and error of manual joining, the material is Q235B or Q345B. 2. The material of mould wheels is hammer or cast steel, wheels are made by automatic Panasonic welding robot, high welding strength and less welding stress. 3. Our moulds adopt intermittent welding technology, welding method is CO2 gas shield welding, we also use Panasonic welding machine and mixture gas to weld moulds, a solid solder joint appearance, there is no brittle fracture caused by manual welding, oxidation, solder false. 4. Our company has introduced 18m heavy duty lathe, the mould below 12m adopts whole lathe machining to improve concentricity of moulds. 5. Our customers can choose different types of steel plates and flanges. 6. The processing equipment of join plate is from the previous planer processing technology to the milling machine processing technology, improved production efficiency, saving labor costs.
