Plasdan was estabilished
as a Danish – Portuguese
 venture in 1989,
in Marinha Grande.

In its early days, Plasdan’s core activity was the sales of injection moulding machines and associated equipment. As business grew, it ended up extending its practice to the mould engineering and project management areas, as well as commencing sales of its own range of thermoplastic equipment.

In the late nineties, with the boom in the mould manufacturing sector, Plasdan decided on getting and got its ISO-9001 certification.

At the start of the millennium, Plasdan starts the manufacturing of a complete range of add-on multi-shot injection moulding systems. Since then, this area has been continuously growing within the company, and has become what is currently the company’s main activity.

Addon Injection units and complex tooling without automation is like an out of focus lens, hence, Plasdan Automation was setup in2008 to complement current activities and fulfil growing market demand.


At this moment, and more than ever, the company is committed to the manufacture of the most innovative and efficient add-on systems for the multi-injection moulding industry.

There is a special effort in the area of co-injection systems and hot-halves as well as added focus to injection blow-moulding on normal IMMs.


Added Certification NP 4457:2007 for Research, development and innovation of equipment and automation for thermoplastics.


Launch of new range of products for
1. co-injection valves and tooling.
2. Developed and launch to market of the Plasdan injection blow moulding systems.
