Molding is a process for processing plastics. It is also known as compression molding. The functional principle is that a molding compound is inserted into the cavities of the mold.
The mold is then closed, using heat as well as pressure. After the cooling process, the workpieces can be removed. They have now assumed the shape specified in the tool.
The molding compound for molding usually consists of semi-finished products that have already undergone shaping production steps such as extrusion. Molding can be distinguished from injection molding by the fact that solid blanks are inserted into an open mold.
Injection molding machines, on the other hand, press molten plastic into a closed mold.
#1 Definition Molding
Molding is a manufacturing process for plastics processing. According to DIN 8580, it belongs to the group of pressure forming.
#2 Importance of molding
Molding is mainly used for the production of workpieces in medium quantities. In principle, injection molding is suitable for producing the same components in a shorter time, but causes higher tool costs.
