Through this case, we have fully demonstrated our professional ability in the research and development, production and application of silicone rubber products, and can provide high-quality and efficient sealing solutions for customers in different industries, helping customers to improve product performance and market competitiveness.  

In the mass production of a customized rubber seal ring, we encountered a sudden decline in the product pass rate, and now the problems and solutions are shared as follows:   Problems that arise: Lack of glue: some products appear concave and incomplete areas on the surface, which seriously affects the sealing of the product. This is due to the complexity of the mold cavity, the rubber material encountered resistance during the flow process, and the cavity could not be completely filled. Bubbles: there are a large number of tiny bubbles inside the finished product, which greatly reduces the physical properties of rubber products and reduces the tensile strength. The reason is that when mixing rubber, the water is not fully removed, and the water vaporizes to form bubbles when heating the die; In addition, the amount of glue filling is too much, and the gas can not be discharged smoothly when pressing the mold, which will also cause bubbles. Excessive flash: excess rubber sheets appear on the edge of the product, which not only affects the appearance, but also increases the workload and cost of the subsequent trimming process. The main reason is that the mold closing precision is not enough, the gap is too large, resulting in the rubber material overflow under high pressure; There is also the molding pressure is too high, beyond the mold design to withstand the range, prompting the rubber material extrusion to form a flash. Solution: For the problem of lack of glue: optimize the mold design, polish the flow path of the cavity, and reduce the flow resistance of the rubber material; At the same time, the molding temperature is appropriately increased, the viscosity of the rubber material is reduced, and the fluidity is enhanced to ensure that the rubber material can fully fill the mold cavity. For the bubble problem: strictly control the drying treatment of raw materials, increase the drying process before mixing to ensure that the moisture content is lower than the standard value; And adjust the filling amount of rubber material, according to the volume of the mold cavity, accurately calculate the filling amount, reserve a certain gas discharge space, install the exhaust device, auxiliary gas discharge. Solve the problem of excessive flash: First of all, repair the mold, adjust the accuracy of the mold, repair the wear part, reduce the mold gap; Secondly, the reasonable molding pressure is re-determined through the test to avoid excessive pressure resulting in the overflow of the rubber material. Through this series of improvement measures, the pass rate of our customized rubber products has been significantly improved, and the subsequent production can also be smoothly carried out, effectively reducing the cost, ensuring the quality of the products, and being well received by customers.
