The main raw material is raw rubber, plus various compounding agents, and some rubber products need to add skeleton materials, or fiber and metal materials; the basic production process of rubber products includes mastication, mixing, Calendering, extrusion, molding, vulcanization, packaging and other processes. Also due to the good physical and mechanical properties of rubber products, they are widely used in various industries.
Rubber products plus various compounding agents are auxiliary materials added to improve certain properties of rubber products. The fiber materials of rubber products are (cotton, hemp, wool and various artificial fibers, synthetic fibers) and metal materials (copper wire, steel wire) are used as the skeleton material of rubber products to enhance mechanical strength and limit product deformation.
How to produce rubber parts Products that require high precision, such as seals, gaskets, oil seals, O-rings, etc., also need to be trimmed and deburred. The available methods include manual trimming, mechanical trimming and Freeze trimming.
1. Manual trimming: labor-intensive, low-efficiency and slow.
2. Mechanical edge trimming: mainly punching, grinding wheel edge grinding and circular knife edge trimming, suitable for specific rubber sealing products that do not require high precision.
3. Frozen edge trimming: special frozen edge trimming machine equipment, the principle is to use liquid nitrogen (LN2) to make the burr of the finished product brittle at low temperature, and use specific frozen particles (projectiles) to hit the burr to quickly remove it. Raw edges. Freezing trimming has high efficiency, low cost, and is applicable to a wide range of products.
