Company Strength

We've brought in a batch of advanced equipment in the industry. Our rubber and plastic sealing strip production line was built around technology that's fairly advanced on the international level. We've revised and upgraded it several times over the years, so it's become more standardized and reliable. The machinery is solid, and our management keeps up with it, so the product quality has stayed pretty consistent.

We make sealing strips for windows and doors, curtain walls, automobiles, shipping containers, freezers, as well as sealing rings for paint bucket lids.

We are extremely rigorous about quality. From raw materials to finished goods, QC is watching every step. Our testing capabilities are comprehensive, we've got vulcanization testers, densitometers, abrasion testers, tensile testing machines, optical projectors, and hardness testers, ensuring all required inspections are fully covered.
