How to Order an Industrial Part in Kerman

If you have never commissioned an industrial part before, it is not obvious where to start. This is what the process actually looks like.

First: you do not need a 3D file

This is the most common misconception. Many service shops say "send us a ready file" — which puts responsibility for the design's correctness on you.

The real route can start from any of these:

• The physical part itself (intact or broken)
• A photo with a ruler or calipers beside it
• A hand sketch on paper
• An old drawing, even an illegible one
• A verbal description of what the part has to do

Building the 3D model and the drawing is part of the service, not a prerequisite for it.

What information helps

The more of this you can give, the faster and more accurate the quote:

1. Where does the part work? On what machine, in what assembly. This is the most important question and the one least often asked.

2. What happened to it? Broken, worn, or not yet made at all?

3. How many? One, ten, or a thousand — this determines the manufacturing method.

4. What is it made of? If you do not know, that is fine; just say whether a magnet sticks.

5. Load and temperature. What does it have to survive? Does it rotate? Take impact? Get hot?

6. How urgent is it? This directly affects the process choice.

7. Rough dimensions. Even "about 10 cm" helps.

How to take a useful photo

• Put the part on a plain, light background
• Place a ruler or calipers beside it — that gives scale and does half the work
• Shoot from three angles: front, top, side
• If it has holes or threads, add a close-up
• Use good light and avoid direct flash

How pricing works

There are two separate costs, often confused:

Design and drafting is priced by:

• Geometric complexity
• Number of parts in the assembly
• The accuracy the application actually demands
• Whether reverse engineering is required

Manufacturing is separate and depends on process, material and quantity.

Important: after seeing a photo or the part, you get a specific fixed quote, not an open estimate. If somebody gives you a number without seeing the part, that number is meaningless.

Realistic timelines

Type of work	Typical time
Drawing for a simple part	2–4 working days
3D model + drawing, ordinary part	4–7 working days
Reverse engineering one part	5–10 working days
Multi-part assembly	2–4 weeks
Manufacturing (after the drawing)	Depends on shop and method

The schedule is agreed and committed before work starts, not midway.

The route, start to finish

1. First contact — you send photos and a description
2. Review and consultation — we discuss function, load, material and quantity
3. Quote — a fixed price and schedule
4. 3D design — the model is built and reviewed with you before drawing work begins
5. Manufacturing drawing — with tolerances, surface finish and material
6. Process selection — cost and lead time compared for your actual quantity
7. Prototype — one piece to check fit in the real installation
8. Revision and production — prototype feedback folded in, then production

Each stage is confirmed before the next begins, so expensive corrections do not pile up at the end.

If you are outside Kerman

Design and drafting are done entirely remotely, over Telegram or Bale. For reverse engineering you either ship the part or, with guidance, take the measurements yourself.

Three common mistakes

1. Going straight to a workshop with no drawing. The shop builds from what you said. If the result is not what you wanted, there is nothing to arbitrate against.

2. Asking for tight tolerances on everything. "The more accurate the better" is wrong. A tight tolerance on a face that does no work is just money.

3. Making ten without a prototype. Always make one and fit it first. Always.

If you have a part and are not sure where to begin, send a photo. The first consultation and quote are free — and if the answer is "this is not a job for me," I will say so.
