Rubber seals from material to size to be able to control in place

Rubber as an ancient material used very early for the ancestors, when most of the rubber can only be used for adhesive and waterproof clothing. Because rubber has a fatal drawback, is too sensitive to temperature. It will become soft and sticky at a slightly higher temperature, and will have a bad odor;

This nature of rubber plagued the rubber industry, but rubber also has high elasticity, plasticity, durability, waterproof, insulation and a series of excellent properties, so Goodyear determined to study the rubber modification. In January 1839 Goodyear accidentally rubber, lead oxide and sulfur together heated and get a similar leather-like substances. This material does not decompose at higher temperatures than the commonly known elastomeric rubber.

With the development of science and technology and the improvement of living standards, the formulation of rubber seals, based on the physical properties of the formula (such as hardness, pressure rate), qualitative, quantitative design rubber seal mold, this is very important No matter how good the material is not a reasonable shape design, can not play a good rubber advantage.

Good rubber seal formulations, rubber seal design, but to ensure the basic start of product quality, dimensional tolerance control is a measure of a manufacturer's production technology capacity of high and low important criteria for each batch of qualified products , Generally with the naked eye and feel is not feel the difference in size, and now the market there are many different sizes of rubber seals can be directly with the naked eye to see out with the feel, so that the size of the gap mounted to the seal , There will be some places tight, loose in some places, rubber seals and profiles flash some gaps in some places, or simply after a period of time from the rubber seal parts fell off, so the seal will lose the sealing ability.

Production of high technical capacity of the manufacturers, are generally implemented strict quality system, measuring the size of the key products produced products, the staff focus on measurement, control of these key dimensions.
