 Casting Capability

  As a professional precision casting factory, we only produce high quality precision castings. Castings with distinct edges and corners, size precision (critical dimension can reach ct5-ct6 level) and surface smoothness (casting surface roughness Ra 6). For castings can also be plastic, with the press machine, fixtures and measuring tool calibration castings.

  Machining Capability Inspection Capability

  We have produced more than 700 different types of precision castings, these products are mainly exported to Europe, the United States and Japan, our engineers and workers are familiar with the overseas customer engineer standards and quality requirements. As far as now my company has 18 sets of machining center, 3 sets of inclined bed, 21 CNC machine tools, 1 sets of CMM inspection center, 3 sets of manual lathes, milling machines 2, 18 Taiwan 1 Taiwan drilling machine, ultrasonic cleaning machine, 1 sets of vibration grinding machine, 1 sets of welding machine.
