With the continuous development of China's economy, the cost of human resources has been rising steadily. Labor-intensive enterprises that heavily rely on human resources are facing increasing pressure. The same is true in the production and manufacturing industry of silicone rubber products. Removing burrs from products often requires a large amount of manpower to handle, especially for products with many burrs that are produced in large quantities, which is time-consuming and labor-intensive. Therefore, a "freezing burr removal" process has increasingly gained favor among silicone rubber product manufacturers!
The burrs on the finished products of silicone rubber parts are usually thinner than the products themselves. When in a frozen and low-temperature state, they will undergo brittling before the products do. The freezing burr removal machine takes advantage of this principle. It uses high-speed jets of plastic pellets to impact the products within the time difference when the burrs start to undergo brittling but the products themselves still have elasticity. This enables the complete removal of the brittle burrs. Because the temperature of the burrs drops faster than that of the products themselves, the burrs can be removed without damaging the products themselves.
Rubber and plastic materials belong to high polymer materials. They exist in different phases at different temperatures. From the perspective of phase, it is merely a change in mechanical state, which belongs to the physical level and does not involve any chemical changes. When the product is returned to normal temperature after removing burrs through freezing, all its original properties will be restored. The freezing burr removal machine utilizes the unique phase characteristics of the material in low-temperature conditions to efficiently and safely perform burr removal work.
Compared with the traditional manual edge removal method, freeze edge removal has the advantages of high efficiency, low cost and stable quality. Therefore, it has been widely applied in the production of rubber O-rings and other silicone rubber products. Yongyong Silicone Rubber has been dedicated to silicone rubber products for 23 years and provides a complete set of solutions including silicone rubber product manufacturing, material research and mold development.
