4. Forming vulcanization process - operating speed

It refers to the operating speed of sulfur chemical adhesive and products. Rubber vulcanization is a chemical reaction. Rubber materials are vulcanized from the hot mold. For the first mock examination porous products, the shorter the distance from the first piece of glue to the last piece of glue, the better. Put the glue on the mold and immediately close it. Otherwise, mold dirt, hot mold, burr thickness, deformation and other abnormalities are likely to occur. When using this product, it is easy to use pneumatic assisted blow molding, but it will lower the temperature of the mold. If you are not proficient in operation, it is most likely that the mold temperature is getting lower and lower, leading to unfamiliarity with the product. Additionally, you need to adhere to the mold, which is the most likely problem for beginners. In the production of smooth rubber sheets, the influence of glue application speed, mold sealing speed, and mold opening on the quality of smooth surfaces is most obvious. Why do some products have strict appearance requirements and choose to hang the mold? One of the main principles is also here!

5. Forming vulcanization process - Product placement

Refers to the shape of prefabricated parts, which can be long bars, small squares, or circles. The thickness, length, and width of the compound must be close to the product. The closer the shape is to the product shape, the shorter the flow time in the mold, the shorter the flow distance, the thinner the wool edge, the less adhesive used, and the higher the product qualification rate.

6. Forming vulcanization process - Compound weight

The weight of the compound must be greater than the weight of the product, otherwise there will be a shortage of glue. But the more glue there is, the thicker the wool edge of the product and the larger the size. The weight of the compound is directly related to the shape of the compound. How to use the least amount of glue to produce the most reasonable shape without lacking glue is a reflection of the technical level of the molding personnel. The weight of the glue is sufficient, but the length is longer than the mold, and there will also be a lack of glue. The shape and weight of the glue are appropriate, but if you put it down, There will be one thin side and one thick side, and in severe cases, there will also be a lack of glue and hair thickness on one side. The shape of the adhesive material is appropriate and the total weight is appropriate, but uneven shear thickness and uneven filling of the adhesive can also lead to a lack of adhesive. When there is insufficient glue in the product, do not rush to intensify the glue. Instead, take a complete mold with burrs, check the weight of the product, and then check if the thickness of the product is uniform. Finally, decide whether to add the material. The technical content and experience of the molding foreman are very important!
