Metal or Plastic?

Metal Part Or Plastic Part?

The choice of material depends on the properties required by the part, its use and its environment. Generally, the high mechanical and thermal resistance of metals (aluminium, steel, stainless steel …) are put into perspective with the benefits of thermoplastics (polyethylene, polypropylene, polyurethane, polycarbonate, PCABS, polyamide …): lightness, elasticity, electrical insulation, chemical resistance, dimensional stability, design freedom. The achievable gains by the replacement of a metal part by a plastic part are even more important when project issues concern the weight, appearance, noise, cost reduction, optimization of assembly and / or process. MPI helps you define thermoplastics material or metal-plastic hybrid solutions adapted to your problematics.


Success Story: Professional Philips Led Lights
Challenge: Replacing A Painted Metal Part By A Plastic Part

plastique vs metal

PhilipsFor economic and environmental reasons, Philips aims to change three professional indoor LED lighting ranges. For these three ranges, MPI develops plastic parts to replace painted aluminium castings. The challenge was to create a plastic part, moulded in series without recovery and with the right shade, and properties equivalent to the painted aluminium part. The challenge was daunting in terms of definition, of eco-design of parts, for choosing materials and dyes, for the production. All was not easy but the project was a collaborative success, these lightings became the runners of the concerned Philips’ site.
