Edge treatment of rubber products

2024-10-30127
After rubber products are made and molded, there will be certain product burrs on the product. The rough edge treatment of rubber products has high requirements for the appearance of the product, and is also inevitably related to the product price. The processing of rough edges in general rubber products also incurs certain production costs for manufacturers. Therefore, while ensuring product quality in the process of rough edge processing, manufacturers pay more attention to the efficiency of rough edge processing in rubber products.

The rough edge treatment of rubber products is often divided into the following categories: manual trimming: high labor intensity, low efficiency, and low qualification rate. And mechanical trimming: mainly includes punching, grinding wheel trimming, and circular knife trimming, suitable for specific products with low precision requirements. Three frozen edge trimming: a specialized frozen edge trimming machine equipment that uses liquid nitrogen (LN2) to make the finished product's burrs brittle at low temperatures, and uses specific frozen particles (pellets) to strike the burrs to quickly remove them. Frozen edge trimming has high efficiency, low cost, and wide applicability to products, and has become the mainstream process standard.
Rubber products are generally processed with burrs according to the shape of the product and the customer's needs, in order to produce high-quality products more quickly and effectively.
