Basic characteristics of rubber product molding

The molding of rubber products is one of the important processes in production. With certain machine equipment and process methods, the process of manufacturing semi-finished products of various structures and different specifications and sizes is the molding of products.

rubber products

There are many types of rubber products, and the structure of the products is different. Therefore, the molding methods are also simple and simple, with physical processes and chemical processes. The structure of a single product, such as a sealing strip, a pure rubber tube, a rubber sheet and the like having a certain shape and size, can be completed by a calender or an extruder. Latex products such as balloons, gloves, etc., the impregnation method for forming, the complex structure of the product, consisting of several or more than 10 parts, it is necessary to combine the parts by a molding process using a more precise molding equipment, such as The molding of tire tires, conveyor belts, V belts and other products. The advancement of modern science and technology and the emergence of new materials have made the new rubber industry such as injection molding and casting method widely used. The injection method combines two processes of forming and vulcanizing for the manufacture of glue technology, sealing products and shock absorbing products.

The molding of rubber products has the basic characteristics of the section:

(1) The molding method is required to be simple, easy to control, and the product specifications are accurate;

(2) Require semi-finished products to be as close as possible to the dimensions of the finished product, and the dimensional specifications during the vulcanization process are minimal;

(3) The molding of complex structural products requires that the number of parts be reduced as much as possible and that the parts have a higher bond strength;

(4) The molding equipment requires mechanization, high degree of automation, high precision, and can ensure that the finished structure meets the technical requirements;

(5) Low labor intensity and high production efficiency.
