Sealing failure is mostly caused by incorrect material selection. customized seal providers will recommend materials based on the pressure, temperature, and contact medium you provide.
For non-standard shaped parts, customized seal providers can provide a complete set of services from product design, prototype development to production and processing. They can not only follow the drawings, but also use their experience to help you optimize groove design, adjust tolerances, and even avoid product defects through mold flow analysis, improving yield from the source.
Legitimate suppliers support mold making based on drawings and samples, and provide small batch sample services. This allows you to conduct machine testing before placing bulk orders to verify the sealing effect under actual working conditions, avoiding blind mold opening and causing the entire batch to be scrapped.
Professional suppliers will conduct compression permanent deformation, hardness, medium resistance, wear and tear tests on customized parts.
In addition to the seals themselves, customized seal providers usually provide matching accessories such as retaining rings and dust seals to ensure system stability.
