Rubber Products Appearance Regularity

The unvulcanized compound is a viscous fluid at high temperature and pressure, and during the vulcanization of the mold, the compound is filled with mold cavity, Rubber Products and some of its remaining (in order to prevent the lack of glue and filling the compound in the mold cavity, Of the excess) overflow vulcanization, it constitutes a spill - that is, flash. Once the composition of the flash, in order to make the appearance of regular, Rubber Products beautiful, it is necessary to get rid of this process known as trimming. The requirements of the trimming are standard and accurate. In the practice of production. Commodity trim is usually time-consuming, labor-intensive, for the strict requirements of the goods, in the trimming when a little careless that may waste off the product, it is necessary to be treated with caution. Generally speaking, the smaller the standard standard of goods, Rubber Products the more chaotic configuration, the higher the difficulty of trimming, waste more.

1. craft trimming. The operator holds the tool, along the outer edge of the product, will gradually repair the flash. This is the initial approach. Low power, difficult to ensure quality, especially for the configuration of the mess, the accuracy of the high demand for goods is difficult to complete, Rubber Products in the net, and very simple damage to the goods ontology and flash connection. Usually leaving the teeth marks, gaps, and then leave the oil spill, leakage and other effects of the seal after the doubt. Other Craftsmanship on the operation of the degree of proficiency is also very good.

2. mechanical trim. In order to travel power and quality, there is a mechanical trim. More common is a rotating edge with a dedicated electric trimming machine. Rubber Products The blade used must be highly matched with the product standard. Assume that the inner and outer edges of the product have a flash. You can program into a double edge, multi-edge. To finish once finished. Mechanical trimming of the processing accuracy across the trimming, power also has doubled travel, especially for a multi-cavity products, Rubber Products in accordance with the display and distribution of goods, the program with the matching tool. To be a commodity after the mold. Can be the whole version of the set, once finished punching. In the cooperation of heating, Rubber Products one can repair dozens. Typical, for example, is a medical plaster. The key is to punch the temperature necessary to master, to prevent high after the adhesion.

3. Frozen trimming. Will vulcanize the product together with the flash, in the frozen conditions in addition to the edge. For decades, with the choice of refrigerated media, replacement and mechanical action to improve the frozen trimming has also experienced several generations of improvement, Rubber Products mature and perfect, operating power and processing quality has been a clear road. The process is to allow vulcanized goods in the frozen and dynamic conditions to reduce the temperature, so that the flash into the brittle situation. And then through their own conflict between themselves, or in the rotation, oscillation, Rubber Products shaking and other dynamic conditions, with the help of conflict and remove the flash. Perhaps, the rigid pills of media to a certain speed to repair the goods to impact, and then remove the flash.
