SOP (Standard Operating Procedure) are applied for all the manufacturing process, including raw materials check, CNC EDM, deep drilling, mold assembly, trial, packaging and other manufacturing processes management. With full Process control, components are machined according to data to make zero-fitting mold. Technical standard system provides full process technology guide during manufacturing, so as to reduce repeat technology study and monitor the manufacturing process for shorter lead time, lower cost and higher quality to meet customer individual needs. High precision equipment plays big part for the guarantee of good quality. Every year BKM continue to put investment on purchasing new machines and maintenance for existing machines.
