History, how it all started

Rena Castings was founded in 1955 by taking over some departments of Sales Office Venlo. In the beginning mainly religious articles and name plates were made. Five years later, in 1960, the company started producing technical products. In the intervening years, Rena Castings has undergone several transformations.

For example, the coquilles were replaced by smaller die casting machines and the materials lead, tin, brass and zamak disappeared. The material aluminium has always remained, which is why Rena Castings has specialised in this field. Since then, Rena Castings has acquired an enormous amount of technical knowledge in the field of aluminium high-pressure die casting and CNC machining.

Sales & Development

The Sales & Development department is the first and most important point of contact that you, as a customer, have within Rena Castings. This starts as early as the development phase, in which you make your concept, your wishes and requirements known.
The strength of Rena Castings is that we can convert these ideas and requirements into your high-pressure die casting component by means of in-depth engineering.

We can save costs for you at an early stage!

"After all, good design leads to optimal control of production costs."


Sales & Development remains your central point of contact within Rena Castings. This applies to the quotation process, but also during the entire technical realisation of your new product. Short, clear lines.
We ensure the right communication with our toolmakers, the various production departments and our logistics centre. At the end of the line, you can expect a solution that fully meets your specific requirements!

Your Sales & Development contacts have an excellent technical background. They specialize in our processes and therefore know exactly what the possibilities are with regard to your product and its production.
