1. Water purifier filter silica gel waterproof sealing ring customization
This article first introduces to you to customize a (filter with groove waterproof silicone sealing ring) size design, sealing performance and other details. First of all, a grooved sealing ring should be customized to confirm the influence of the roughness of the mating surface of the filter element on the sealing performance, which is mainly used for the filter element components to prevent the leakage of liquid and gas media under static conditions.
Groove sealing ring size: groove bottom diameter, groove width, groove depth data, determine the size of silicone sealing ring, generally can be confirmed in this way, groove bottom diameter/1.04 (tensile rate calculated by 4%) = O-ring inner diameter; Groove depth * 1.2 (compression rate calculated by 20%) = O-ring wire diameter: considering that the O-ring section will deform and spread out after compression, the groove width is generally about 1.3 times of the wire diameter. The material of waterproof sealing ring is best to choose the sealing ring made of silica gel, which has the best water resistance and waterproof performance. Its anti-aging, ozone resistance and permanent deformation are the best materials for waterproof ring.

2. Fully sealed solid food grade waterproof silicone seal ring
Silicone sealing ring is a solid body is completely sealed, waterproof ring made of food grade raw materials, contact with water will not be contaminated by harmful substances, is non-toxic tasteless edible environmental protection materials.
In the solid-state oil pressure process accounts for more than 50% in the silicone industry, the largest demand is also the solid-state molding process, which can be made of materials with different hardness, and the proofing of hardness also affects the normal use of products. Some sealing rings only need products with high hardness in daily life or industrial products, and whether sealing rings will produce some problems with high hardness has become a topic of concern to us.
In terms of precision, many precision electronic components and small mechanical seals may require higher precision of products. Therefore, customization of small sealing silicone rings may require dimensional tolerance requirements. High hardness does have certain technical requirements in the silicone product manufacturer industry. The development structure of the mold has certain influence on product vulcanization. Secondly, has the exhaust groove of the mold really been pulled up?
And the most important thing is whether the product can meet your needs? Many industrial rubber sealing products are gradually replaced by silica gel materials. The main reason is that it has better elasticity and can be used normally even in different temperature environments. The toughness and pull-up rebound strength can be divided into many different materials, including common pulling force and pure high pulling force raw materials. Different rubber materials can produce different sealing effects for different fields, mainly depends on the role of your product in what areas, different roles can also be used in different ways of sealing!
