Inapal Plasticos SA has over 40 years experience in the automotive industry, first with sheet metal parts as Inapal SA and later with composites. We started working with SMC in the 80s of the twentieth century and then later started to produce in GMT, LFG and LFT.

We currently have two manufacturing units, one in the north of Portugal, in Leca do Balio and the other in the south, in Palmela, near the VW Autoeuropa industrial park. Both are equipped with modern equipment, among which we highlight the latest generation Diefenbacher presses and two Diefenbacher LFT lines.

The list of our clients is extensive and is all over the world: Portugal, Spain, France, Germany, England, Italy, Slovenia, Brazil and Mexico.

Our knowledge and experience in the field of composites and plastics make us a major player in the development and production of products in SMC, GMT, LFT, LFG as well in injected parts.
