Before the rubber O-rings are delivered to customers, in terms of production inspection, our Haisheng rubber is strictly controlled to achieve zero defects.
Rubber products such as rubber O-rings are in a series of processes such as inquiry, ordering, shipping, receiving, and using. The receiving link is also a very important part. It actually checks the products ordered before use. Haisheng Rubber recommends starting from the following aspects:
1) Visually inspect the packaging for damage to avoid damage to the seal ring;
2) Check whether the size, material hardness, quantity and color indicated on the outer packing of the seal ring are consistent with the sales order;
3) Visually inspect the seal ring for burrs, bad flashes, pits and breaks, etc.
4) Checking the quantity: If it is a large size and the quantity is not large, it can be in the form of points; if the size is small and the quantity is large, it is recommended to use an electronic balance to check the quantity of each seal ring by weighing. ;
5) Confirmation of dimensions and tolerances: Vernier calipers can be used to measure the size of the seal ring, which is carried out in the form of random inspection. Suggestions for random inspection rules: 500 ~ 1000, 5%; 1000 ~ 5000, 3%; 5000 ~ 10,000, 2%; 10,000, 1%.
Rubber O-ring products have fine workmanship, smooth surface, no pinholes and no burrs, and the minimum accuracy can reach ± 0.01mm. The rubber apron has excellent abrasion resistance, weather resistance, high temperature resistance (-60 ~ 250 ℃), ozone resistance and chemical resistance. It has good stability to organic liquids (various oils, fuels, hydraulic oils), inorganic acids, high concentrations of hydrogen peroxide and other oxidants. The rubber O-ring can be used to seal the original parts, and it can also be used as a force application unit for hydraulic sliding seals and dust seals. In mechanical, petrochemical, instrumentation, sanitary, medical equipment, automotive, pump and valve and other industrial systems, it can be said that there is no need for high-precision seals.
For high-precision seals, the production inspection of Haisheng Rubber is strictly controlled, and there is a dust-free workshop to produce rubber seals with higher requirements. If you are interested, welcome to Haisheng Rubber's official website for inquiry
