The T-shaped anti slip and anti release rubber ring sealing protection involves various industries. This method is one of the indispensable processes in our manufacturing of many items. The rubber sealing ring mainly plays a functional role, so it is only designed for the purpose, characteristics, and various performance requirements of the product. Rubber sealing rings are mainly protected by good clamping and support forces, so controlling material shrinkage is naturally important. So many people don't know how to shape the shrinkage of rubber seals when designing, mainly because they haven't found a way yet.

The shrinkage rate of the rubber sealing ring varies with the increase of rubber content and density of the vulcanized silicone material, usually with a value of 0.0013.
The shrinkage rate of the rubber sealing ring changes into a saddle shaped curve as the hardness of the rubber raw material increases.
3. The shrinkage rate of the silicone ring increases with the increase of vulcanization temperature in the silicone processing plant. When the temperature increases by 10 degrees, the shrinkage rate increases by 0.1% -0.2%.
4. The shrinkage rate of rubber products also increases with the increase of injection volume of raw materials. When the quality of rubber sealing ring raw materials reaches 5-10%, the shrinkage rate is relatively stable.
5. The shrinkage of the rubber mixture in the rolling direction and curing flow direction is greater than that in the vertical direction.
6. The better the plasticity of composite materials, the smaller the shrinkage; The higher the hardness of the compound, the smaller the shrinkage.
The more fillers are used, the smaller the shrinkage. The higher the adhesive content, the greater the shrinkage.
For porous cavity molds, the shrinkage rate of vulcanized silicone products in the middle cavity is greater than that of vulcanized products in the edge cavity.
9. The shrinkage rate of injection molded vulcanized products is lower than that of molding.
10. The shrinkage rate of thin products (with a cross-sectional thickness less than 3mm) is 0.2% to 0.6% greater than that of thick products (with a cross-sectional thickness greater than 10mm)
The sealing ring is suitable for installation on various mechanical equipment, and can be sealed in a stationary or moving state under specified temperature, pressure, and different liquid and gas media. Various types of seals are widely used in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and various instruments and meters. Rubber sealing rings are mainly used for static sealing and reciprocating sealing. When used for rotary motion sealing, the sealing device rotates at low speed. Rubber sealing rings are generally installed in rectangular cross-section grooves on the outer or inner circle, playing a sealing role. Rubber sealing rings can still provide good sealing and damping effects in environments such as oil resistance and wear resistance.
The rubber sealing ring is placed in the inner chute of the water bottle cap, mainly serving as a waterproof seal. Mainly used for waterproof sealing and insulation of daily necessities such as water bottles, insulated boxes, insulated boxes, insulated cups, ovens, magnetized cups, etc.
Please choose a food grade rubber sealing ring, which has good sealing performance and is waterproof and leak proof; Completely odorless; High temperature heating does not deform and does not produce harmful substances; Good tensile performance after special testing; Passed food certification.
