About us

Engineering company DCT-70 specializes in consulting the design of die casting dies for aluminium, magnesium and zinc alloys. The company is based on a rich 10-year experience in high pressure die casting and in the right direction of education. We offer our services worldwide, we support companies in English, Spanish and Polish.

 

The owner of the company is Andrzej Oniszczuk,

who has wide  experience in working in die casting foundries

with alloys Al, Mg and Zn at the positions of a technologist,

project manager and foundry manager.
