For more than two centuries after the first extrusion process patented by Joseph Bramah in 1797, it evolved into many types. From metals to plastics for making products of different shapes and sizes. Their growth is rapid in the last few decades, with the global plastic extrusion machine global market size growing at a CAGR of 3.8 % from 6,057 million USD in 2017 to reach 8,244 million USD in 2025. It is the reason that an extrusion machine for automotive wires is on the rise every year. Importance of extrusion machine for automotive wire Only the best extrusion machines made by experienced manufacturers will provide the appropriate automotive wire. And on the contrary, buying inferior wires could cause accidents due to their substandard conditions and not withstand wear and tear for even a short period. Only wires made by close monitoring of the extrusion process and having enough understanding of its many parameters that include, among others ● ● ● ● ● ●
Viscosity, Viscosity variations with shear rate Temperature Extensional flow Elasticity Slippage of material overheated surfaces
Types of Automotive wires Apart from choosing the right manufacturer of extrusion machines for automotive wires, it is essential to select the right automotive wire type for many purposes. It needs proper understanding, and using the wrong wires will cause failure and lots of hardship. Hence using automotive wires that guarantee real specifications, gauge and comply with ROHS and SAE J1128 standards are the best. The following are some of the best automotive wires that are excellent for use in automobiles.
Primary or GPT wire Primary wire is the most common automotive wire for many general purposes. Being resistant to chemicals, acids, oil, and others, it finds use in tight spaces due to its multi-stranded core and flexible insulation features. Motor wire or Hook-U or 1015 wire
