After rubber products are made and formed, there will be certain product burrs on the products. On the one hand, the burr treatment of rubber products has high requirements for the product appearance, and on the other hand, it is also inevitably related to the product price. Generally, the burr treatment process of rubber products also has a certain production cost for manufacturers. Therefore, under the premise of ensuring product quality in the burr treatment link, manufacturers pay more attention to the burr treatment efficiency of rubber products.

The burr treatment of rubber products is often divided into the following categories of rubber products: 1. Manual trimming: high labor intensity, low efficiency, and low pass rate. Mechanical trimming: mainly punching, grinding wheel trimming and circular knife trimming, suitable for specific products with low precision requirements. 3. Frozen trimming: special frozen trimming machine equipment, the principle is to use liquid nitrogen (ln2) to make the burrs of the finished product brittle at low temperature, and use specific frozen particles (projectiles) to hit the burrs to quickly remove the burrs. Frozen trimming has high efficiency, low cost, and is widely applicable to products. It has become the mainstream process standard.

Rubber products are generally processed according to the shape of the product and customer needs, so as to make high-quality products more quickly and effectively.
