Our Advantage

1. Advanced production equipment:

CNC machining center, rubber mixing machine, preforming machine, vacuum hydraulic molding machine, automatic injection machine, automatic edge removal machine, secondary vulcanizing machine (oil seal lip cutting machine, PTFE sintering furnace), etc.

2. Perfect inspection equipment:

①No rotor vulcanization tester (test at what time and at what temperature the vulcanization performance is the best).

②Tensile strength tester (press the rubber block into a dumbbell shape and test the strength on the upper and lower sides).

③The hardness tester is imported from Japan (the international tolerance is +5, and the company’s shipping standard is +3).

④The projector is produced in Taiwan (used to precisely measure product size and appearance).
