Raw edge treatment of rubber products
2021-07-19
After the rubber products are manufactured and molded, there will be certain product burrs on the products. On the one hand, the rough edge treatment of rubber products has high requirements on the appearance of the product, and on the other hand, it has an inevitable relationship with the product price. Generally, the processing process of rubber product burrs also has a certain production cost for manufacturers. Therefore, under the premise of ensuring product quality in the process of processing burrs, manufacturers pay more attention to the efficiency of rubber product burrs processing.
The rough edge treatment of rubber products is often divided into the following rubber products: manual trimming: high labor intensity, low efficiency, and low pass rate. And mechanical trimming: mainly includes punching, grinding wheel edging and round knife trimming, which is suitable for specific products that do not require high precision. 3. Frozen trimming: dedicated frozen trimming machine equipment, its 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 a wide range of applicable products, which has become the mainstream process standard. Rubber products are generally treated with burrs according to the shape of the product and the needs of customers in order to make high-quality products more quickly and effectively. |
