Our Clients

Industry Expertise

Tool Industry

Precision tools require flawless surfaces. We remove coatings and prepare tools for re-electroplating — quickly and with care for the material.

Construction Industry

Steel structures in construction are permanently exposed to weathering. Our rust removal and passivation processes significantly extend service life.

Electroplating Industry

For the electroplating industry we handle pre-treatment and stripping of components — the prerequisite for uniform, adhesive coatings.

Client Feedback

What our partners say

Excerpts from B2B project enquiries and follow-ups.

Sent in a stripped chrome mould insert that two other contractors had refused. DI returned it within 5 days — base material untouched, ready for re-plating. Saved us a full re-tooling.
Werkzeugbau-Leiter Tool & die shop · NRW
We rely on DI for bead-blasting stainless components before assembly. Consistent finish across batches, paperwork on every delivery, prices that hold. Exactly what an OEM supplier needs.
Procurement Manager Metal-fabrication SME
Used the free sample run before committing. Within two days I had the part back with a clear cost projection. The transparency convinced us — we've now placed three follow-up orders.
