PRODUCTION OF SMALL SERIES (FORMING IN SILICONE FORMS)
The optimal solution for the production of small batches of plastic products is vacuum molding into silicone molds. This technology allows you to get high-quality material at a low cost. The parts obtained with this method cannot exceed a dimension of 600x600x400 mm and a mass of 3 kg. The accuracy of the copies obtained by this method is very high, and it is usually around +/- IT14 / 2.
How is Silicone Produced?
Two-component polyurethanes are used for casting. The mass moves along the sprue channels and enters the silicone mold which it evenly fills. The possibility of formation of air has been eliminated because the casting occurs in the vacuum environment. The lack of air increases the quality and strength of the products.
The two-component polyurethanes used for casting can have the physical and mechanical properties of almost any plastics and materials such as:
- structural plastics
- Transparent materials (which makes it possible to manufacture optical products)
- Rubber with a hardness ranging 30-90 Shore units.
In addition to this, polyurethanes allow the creation of heat-resistant products that can withstand up to 120 degrees temperature.
The products are usually identical to the master model. Most of the time, the types of invoices that are available are glossy, matte, fine, coarse sand and so on.
Why this Technology?
The technology is capable of embedding elements into the product. It can also give you the details of any color in the catalog “RAL.”
Silicone molds, in general, are very easy and inexpensive to manufacture. It is also capable of withstanding up to 25 shot. Matrixes can be either for solid filling (one-sided) or detachable. It is also the latest materials for the manufacture of complex three-dimensional products.
Conclusively, the technology provides limitless possibilities for manufacturers to produce plastic parts and the products of high quality. Currently, the technology is used in testing batches before being put into production.
