Dressing Shandong import NBR o-rings: uncured rubber O-ring NBR for viscous fluids at high temperature, pressure, and to the vulcanization molding stage, plastic materials quickly fill the cavity, its extra parts (in order to prevent shortage plastic, filled in the mold cavity of plastic materials, certainly maintain a certain excess) overflow vulcanization, has become the excess glue type (also known as scrap, flash). Once the type overflow edge into, to make the appearance neat and beautiful, must be removed, this process often called trimming. For trimming the size requirement is accurate, neat appearance. In the actual production. Trimming products are often time-consuming, consuming work, strict requirements for the product, when trimming a little careless waste of time that could be treated with caution. In general, the smaller the dimensions of the product, the more complex configurations, the higher the difficulty of trimming, the more waste. Install the O-ring (O-type rubber seals) requirements before installing the import NBR o-ring (O-type rubber seals), check the following: 1. The introduction of angle is processed by drawing a sharp edge chamfer or whether round; 2. whether burr inside diameter surface pollution; 3. Is seals and parts already apply grease or lubricant fluid (to ensure media compatibility elastomer recommended to lubricate the seal with liquid); 4. not use greases containing solid additives, such as molybdenum disulfide, zinc sulfide. Manually install the O-ring (O-type rubber seals): 1. Use no sharp edges of the tool; 2. Ensure that the O-ring (O-type rubber seals) do not distort, not excessive stretch O-ring (O-type rubber seal Circle); 3. Try to use aids to install the O-ring (O-type rubber seals), and to ensure correct positioning; 4. For sealing strip bonded to import NBR o-ring (O-type rubber seals), can not be stretched at the connection. O-ring trimmer features: 1. High efficiency: A O-ring trimmer can handle the average daily amount equivalent to 80-100 trimming skilled workers. 2. Low cost: the use of O-ring trimmer can greatly reduce production costs, such as savings trimming, management, materials, tooling costs and workshop area. 3. High quality: Import NBR o-ring trimmer according to production requirements perfectly burr removal products, and can deal with some special structure does not handle the artificial generation of product damage. 4. Environmental protection: Frozen deburring physical approach to the case, no waste discharge, environmental pollution.
