Raw material

The best quality raw material is one of the most important fator to the final product. CSB always purchase the highly raw material ,Choses the API holding  suppliers that to positive our quality of products

The incoming raw material test is first process, our engineers check each material one by one ; record; double-check; make sure every material is satisfier.








CSB cooperated with universities for technical cooperation and software developing. Formation analysis software; Mechanical Analysis software and Hydraulics Analysis software are using for our design, After record all the analysis date, 3D Solid Model software helps us build the final model automatically.

Advanced equipments areworked for precision process, 5-Axi CNCs help us to make the precision mould ofmatrix body bit and also steel body. 3 sets of furnaces make sure the matrixbody make up to 22". 4 sets welding work-platform ensure our capability.










Dye penetrate inspection is executed after each process.
3D inspection (7-axis laser scan) is executed by final inspection process
