The Reasons For Affecting the Precision of Silicone Seals

 The reason for affecting the precision of silicone seals?

For products with high precision requirements, it is necessary to function within the range of its tolerance. In the silicone rubber industry, the precision tolerance requirements of products are not very strict. There are often some special silicone rubber electronic parts, silicone rubber precision accessories, and other products that need high precision requirements. So there are some difficulties in the custom processing of silicone rubber products that want to achieve high precision.

The primary reason is the horizontal calibration of the machine. The precision silicone manufacturing machines. The size of the silicone products is better, and the deviation of the larger product size is 0.3-0.5mm or so, which is a common phenomenon. The problem of the machine mainly stems from whether the upper and lower bearings are symmetric, whether the template is symmetric and whether the ground is symmetric and other factors!

The mold precision requirements of silicone products are not very high, many products still have knife lines on the surface of the product, and the precision of the machining process of the mold can reach 0.001mm, so the intuitive point in saying that the precision of the mold does not affect the precision of silicone products, but the industry processing shortcut problem, Silicone rubber manufacturers do not produce and process according to reasonable requirements, the tools are not good, the knife edge is not strictly controlled and so on, which leads to the accuracy deviation of the mold.

Silicone rubber raw material is the most deadly defect of the precision of silicone rubber products. In the silicone products industry, the difficulty of product customization processing is that the softness of the material and the density of the rubber can not be controlled, which leads to serious deviations in the precision, and even the deformation of the product. And through the silicone rubber product manufacturers from the machine mold and the proportion of materials can control it within a certain range, so high precision silicone accessories have special requirements of friends need to confirm whether the supplier has the technology to meet certain precision requirements.

Silicone rubber always belongs to the elastomer, so the size of the product does not have too high requirements for it, so many friends know that its characteristics will be particularly large size, gently extrusion can be assembled to achieve a tight degree, generally speaking, silicone products factory can control the accuracy of the product range of about ±0.05mm, The general error range needs to be determined according to the length and thickness of the product, for small precision seal products will be in a smaller range of control!
