Rubber Products Obviously Marching

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, in the net, Rubber Products 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. Rubber Products 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, 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, Rubber Products once finished punching. In the cooperation of heating, 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, Rubber Products replacement and mechanical action to improve the frozen trimming has also experienced several generations of improvement, 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.

With the drum as the working container, the drum cross section is shown in Fig. 1, and the dry ice is initially selected as the refrigerant. Put the repair pieces into the drum, and perhaps add some work can play a conflict medium. Barrel temperature control in the flash has been crisp and the body of the product is not brittle. In order to be enough to reach this purpose, Rubber Products the flash thickness should be ≤ 0.15mm. The drum is the primary part of the equipment and is octagonal. The key point is to manipulate the placement of the medium, so that the roll cycle to carry on.

The drums are tumbling in the anti-clockwise direction, and the material is dragged along the 1-2 line by gravity and then circulated in sequence. After a period of time, the flash brittle, exactly finished trimming. Rubber Products The first generation of the skills of the lack of place is not complete, especially in the sub-surface two simple presentation of the remaining flash. Rubber Products Factor is the mold program is defective, or part of the plastic layer is too thick (greater than 0.2mm) formed.
