About Cor Janssen

Having gained valuable engineering experience in the Merchant Shipping Industry, Cor became attracted to the rapidly growing Plastics Thermoforming Industry and decided to make the move into engineering plastics. Over 30 years later, after operating with some of Europe’s leading Thermoforming Company’s, he has decided to put that experience to good use and has formed his own consultancy aptly named ‘Thermoforming Consultancy’

Plastics thermoforming has enormous potential and with the influx of exciting new and sophisticated materials coupled with improved process technology, the market is rapidly developing in new and diverse market sectors.

It has been a privilege to operate in these sectors where cutting edge technology has been necessary to develop new markets and it is this in depth experience which has enabled Cor to confidently launch ‘Thermoforming Consultancy’

It is Cor’s technical experience coupled with his ‘front line’ sales experience which enables him to offer a rounded and focussed view on product development as well as all aspects of the plastics thermoforming process.

It is this level of integrity and impartiality which has allowed him to sit on the board of the European Thermoforming Division where he has held the office of Treasurer for over 25 years.


products are all arround us and play major part in our daily lives


Here's some history about thermoforming. Do you know that our technology is the oldest plastic transformation technique in the World? The first mentioning of heating and forming goes back the old Egyptians.

They heated tortoise shells in hot water and shaped them into useful products, mainly food containers. Also in the prehistory of America, tree bark (natural cellulose) was heated and shaped into bowls and even canoes.

But the most modem approach of thermoforming starts in 185O’s when Guttapercha was used to replace ivory for billiard balls. The first thermoforming was obtained by putting cellulose nitrate sheets into metal dies, heated with steam and quenched in water.

The industry didn’t change a lot until 193O’s and as most of the plastic transformation techniques, thermoforming made a big step forwards during the second world war.

In 1942 PMMA fighter/bomber windows were produced as well as relief maps by the US Mapping Service. In 1960 twin-sheet thermoforming was developed and commercialized. There have been more technical advances in the last decade than in the previous fifty years.


European Thermoforming Division

Started in 1992, it has become the widely accepted body and voice of the thermoforming industry in Europe. It provides conferences, training seminars and regular topical news bulletins and is a dynamic network platform that encourages and promotes technical and scientific participation by its members.
