Heat Treatment In Pultrusion


Metal heat treatment is very important in pultrusion mold manufacturing compared with other processing technology, heat treatment generally does not change the shape of the workpiece and the overall chemical composition, but by changing the workpiece internal microstructure, or change the chemical composition of the workpiece surface, giving or improving the workpiece performance. It is characterized by improving the intrinsic quality of the workpiece, which is not generally seen by the naked eye, so it is a special process in the manufacture of machinery, but also the important link of quality management.

In order to make the metal workpieces have mechanical properties, physical properties and chemical properties, heat treatment technology is often essential except for the reasonable selection of materials and various forming processes. Iron and steel is the most widely used material in the mechanical industry. The microstructure of steel is controlled by heat treatment. So the heat treatment of iron and steel is the main content of heat treatment. In addition, aluminum, copper, magnesium, titanium and its alloys can also change their mechanical, physical and chemical properties by heat treatment to obtain different performance.

Three processes of heat treatment for FRP pultrusion mold.

Heat treatment technology generally includes heating, heat preservation, cooling three processes, sometimes only heating and cooling two processes. These processes are interlinked and can not be interrupted.
