Finding industrial parts & components

by Cecile de Veyra (Managing Editor)

No longer a lesser material, in recent years plastic has been increasingly used where metal was formerly the only choice in many industries. Innovations have made it just as strong, with types such as industrial plastic even more rugged than steel. In electronics applications, plastic is the safe material to use for insulation, housings, circuit boards and PCB hardware for its nonconductive nature. Yet it has also been imbued with electrical properties, extending its versatility, in addition to the significant weight reduction and miniaturization offered. Some herald plastic as the future of manufacturing.

However, metal remains just as viable a material, especially for applications exposed to extreme temperatures. Most metals are more heat-resistant, having a higher melting point than plastic. In addition, metal parts can be fabricated using a broader range of methods such as CNC milling and turning, extrusion, casting, injection molding, forging, punching, shearing, welding, stamping and 3D printing.

Regardless, demand for precision parts on both sides continues to rise and in their midst are molds, also known as “the mother of industry,” and dies, which are essential to producing all these components in big volumes.

For buyers looking for metal and plastic fabrication services or molds for industrial manufacturing, here are samples from Global Sources verified suppliers.
