Engineering Plastics

Thanks to continued development and innovation in the field of plastics for engineering, the amount of applications in which these materials have substituted metals is enormous, obtaining important improvements regarding mechanical response, reductions in weight and costs, durability and the elimination of noise.

Our range of products covers from polyimides (PA), polyacetals (POM) and polyethylenes with ultra-high molecular weight. (UHMW PE) to materials with high performance like fluoroplastics or PBI.

Given the wide range of materials, additives and grades that we have, and in the interest of obtaining a better technical response to the specific needs of each application, Bronymec offers its experience and collaborates with its clients in the selection of suitable material and the transition between parts designed in metal to plastic parts.

Manual of tolerances

Plastics have a viscoelastic behavior, which makes the dimensions of the piece change when machined. They present a thermal expansion, in addition to absorbing moisture, which also causes the volume to increase. This phenomenon can also be caused by the relaxation that the material presents once the machining is finished.
