Production
Process control
We established a strict regulations for production, reasonable production control, efficient and duly production management, BOM system, the active promotion of computerizing management, control of materials for the purchase orders. The operation management system, MRP and ERP are adopted, which is able to control exactly from order, displacement of labor, procedure of manufacture, trace procedure, control of production schedule. All of this may meet OEM request.
Maintenance of equipment
• Automatic metal round sawing machine
• Automatic hole-deepening processing machine
• CNC automatic lathe

Conform to demands, customer first, quality first, continuous improvement
Quality
We have passed ISO 9002, QS-9000, and TS-16949.
We insist in TOYOTA 6S lean management system.
QUALITY CONTROL: 100% MPI test
Quality control
Inspect: raw materials, arrival of materials, process and finish goods.
We make use of all kinds control method, such as: CPK control, defects control, in order to assure that our prodcuts are conformed to the quality request. We keep the quality management of the process, trace of products, other related quality information and records completely on file, so that we can provide a professional consulting service to the quality.
Maintenance of Inspection Instrument
To assure the precision of the measuring instrument and its life span, the instrument should be maintained and corrected regularly by professional staffs.
The related correction of quality could be traced to the national laboratory.
To lessen the error of measurment, the cylinder measuring machine and surface roughness meter should be placed at the quality assurance laboratory (temperature and humidity are controlled day and night).
We take charge of the supervision of quality, they inspect every step before delivery, such as; purchase of raw materials, arrival of materials, process and finish goods.
We make use of all kinds control method, such as: CPK control, defects control, in order to assure that our products are conformed to the quality request.
