Which make it suitable for almost all chemical media. It also has the excellent sealing capability , long life and complied with sanitary requirements

★ Wave Springs
  Our Wave Spring especially has its advantage in its special technics, low cost and high & steady quality.
Unlike punch forming process, we use continuous winding and curling process from round edge flat wire, to realize real flexible production and in the mean while to reduce waste of material and avoid damage from stress.
★ Silicon Carbide Products
  Sinlicon carbide is a new type of engineering ceramics with high cost performance and excellent material properties, which make it  widely used in oil, chemical, machinery and airspace, nuclear energy and defense industries.
Quality Assurance
  All of products are manufactured in our modern factories. First-class equipment, professional and efficient team, large scale low-cost production & inspection facilities could ensure consistency & stability of products.
