Molds sheet metal

Mold This process is particularly suited economically to producing small production runs and large-sized products, because molds are not subjected to relatively any pressure during molding and inexpensive thin sheet metal molds can thus be used in many applications. Lightweight cast aluminum and...

In one example, over 150 parts of a steel riding mower have been incorporated into two injection molded thermoplastic panels made from a PC/polyester blend. These are adhesively bonded to a lower fiber reinforced PU lower member. Although the plastic material cost is ten times that of the sheet metal it replaces, economies in assembly, painting and part inventory give the final product a 10% lower cost. 

The molds are not subjected to pressure during molding, so they can be made relatively inexpensively out of thin sheet metal. The molds may also be made from lightweight cast aluminum and electroformed nickel,...

Chrysler specified a modified polymethyl methacrylate (PMMA) laminating resin for the body panels of the high-performance sports car, the 400 bhp 10 cylinder Dodge Viper, which went on sale in January 1992. The transition from styling to production took only three years. The decision to use glass fiber reinforced PMMA resin, molded by resin transfer, was a fundamental departure from established Chrysler practice, where previously all main exterior bodywork had been in sheet metal. However, at expected sales of 3000 a year and a unit price of about 50,000, sheet metal would not have been viable and the annual volume was too low to justify injection or compression molded plastics.

The machining of press tools of large sheet metal parts such as car parts or injection molding tools of large plastic products needs the removal of a large quantity of material to produce high quality 3D surfaces. Productivity is enhanced by reducing the control of...
