Vacuum forming machines come in different quality classes. They can be conditionally divided into: amateur and industrial. We will not consider the amateur type of equipment, since it is impossible to maintain the correct forming technology on such machines. We will focus on the industrial form of equipment. In turn, industrial vacuum forming machines can be divided into simple and fully functional.
Size does not always indicate the quality class of a vacuum forming machine. Equipment can have a large forming field but be simple. Or vice versa, be compact, but remain fully functional. The basis for dividing industrial vacuum forming equipment into classes is functionality. The more options are installed that help the forming process, the more technically complex the product can be made. And the production process will be all the more stable. The basic set of options that is available for simple machines often looks like this:
Unfortunately, on machines with this set of options, you cannot form any products. Firstly, one-sided heating allows forming a sheet up to 6 mm. by thickness. Secondly, the forming technology is much more complicated than it seems at first glance and requires a number of additional options for the manufacture of some products. For example, for forming a shower tray, the accuracy of maintaining the temperature of the sheet during heating and cooling with radiation pyrometers, the accuracy of maintaining the temperature of the mold, adjusting the power of each heater, two-sided heating for uniform heating, a table servo for smooth exit of the mold from the product, etc. are required .
When choosing a manufacturer of vacuum forming equipment, it is important to get not just a machine, but the production technology of a product.
