Spare parts for production lines

When a line stops, you don't wait weeks for a part. We make it to drawing or without one – and can keep critical parts ready in stock for you.

The challenge

Original parts from the machine builder have long lead times, nobody has drawings for many older lines any more, and every hour of downtime costs more than the part itself.

How we solve it

01No drawing? We measure the worn part (3D probing down to 2 µm), model it and suggest a better material or heat treatment – you receive the documentation with the part.
02We make the part complete – machining, heat treatment and surface finishing.
03For regular partners we manufacture urgently, ahead of other orders.
04Critical parts are held in consignment stock and you call them off only as needed.

FAQ

Frequently asked questions

The builder of our machine no longer exists. Can you make the part from an old one?

Yes – that is our most common case. We measure the part, model it, add tolerances according to its function and manufacture it. You receive a drawing and a 3D model, so next time you only order a part number.

How fast can you deliver a part for a stopped line?

Regular partners are served with priority – simple rotational parts typically within 2–5 working days, complex parts within 2 weeks. Critical parts are better kept in consignment stock so you do not wait at all.

What is the critical-parts audit?

Send us a list of the parts that most often stop your production (10 items with a photo or drawing is enough). We return a proposal of what to keep in consignment stock, in what quantity and at what price – free and without obligation.
