Miniature Super Fine Rubber O-Ring Seals O-Ring Rings

The minimum O-ring rubber sealing ring has a cross-section diameter of 0.2MM, with specifications including 0.25mm, 0.3mm, and many other models. For example, an inner diameter of 0.4*0.3 and an outer diameter of less than 1MM. The mold cost for the finest O-ring with a 0.2MM cross-section is nearly ten thousand, and the unit price is estimated to be 0.15-0.2, depending on the quantity, parameters, and material! Due to the mechanical properties of the product, many materials are restricted. For instance, nitrile NBR rubber material is suitable, while silicone rubber O-ring seals cannot be molded. The product accuracy ranges from 0.02-0.01-0.03MM, with tolerances depending on size and material. The precision is very high. Because of the smallest model factors, it is recommended not to overly consider this design size due to high costs and low output. The number of mold cavities is limited. The waterproof performance of the sealing ring is ideal due to its high roundness, and the product is free from burrs, flashes, or other appearance defects, meeting high-precision requirements. The minimum inner diameter is 0.3MM-0.4mm, which is currently the limit for mechanically processed rubber ring molds. Of course, the precision and temperature limits vary among enterprises—some are high, some are low, depending on the processing capabilities of the manufacturer. Generally, imported tools are used for processing. Our company, Huizhou Xiangjiang Lanxin Industrial Co., Ltd., focuses more on mid-to-high-end products with metric tolerances of 0.01-0.02-0.03MM and three cross-section diameters.
