Yes. Many engineering factories in Gujarat can measure a sample part, make a drawing from it, and produce copies. This is common for spare parts for older machines, discontinued components and replacement parts for equipment you already own.
Two cautions apply. You must have the legal right to copy the part, and you should approve the drawing before any production starts.
Check the legal position first
Copying a part can infringe someone else's patent, registered design or trade mark. The rules differ by country and by product. Making a replacement for your own machine is often treated differently from selling copies of a branded part to others.
Before you start, check whether the original part is protected in the markets where you will use or sell it. If in doubt, ask a patent or trade mark attorney in your country. Do not ask the factory to copy logos, part numbers or brand markings. You, not the factory, will usually carry the legal risk in your market.
How reverse engineering works
- The factory measures the sample with gauges, a CMM or a 3D scanner.
- Material is identified by testing, often with a spectrometer for metals.
- Hardness and any heat treatment are measured.
- Surface finish, coatings and threads are recorded.
- A drawing or 3D model is made from the measurements.
- The buyer reviews and approves the drawing, and adds tolerances.
The weak point: tolerances
A sample shows one part's actual size, not the designer's intended size and tolerance. A worn sample may be smaller than new. A good factory will ask how the part fits with its mating parts, and use that to set sensible tolerances.
Send mating parts or their dimensions if you can. Tell the factory which features matter for fit and function. Approve the drawing as your own controlled document, then ask for a first article inspection on the first parts made from it.
Send more than one sample if you have them, ideally including an unused part. Comparing several pieces helps separate the original size from wear. For parts under heavy load, such as gears or shafts, ask an engineer to review the material and heat treatment, because a copy that looks right can still fail early.
Who owns the new drawing
If you pay for reverse engineering, agree in writing that the drawing and model belong to you. Otherwise the factory may claim them, or sell the same part to others. Ask for the drawing in PDF and the model in STEP format, so you can use them with any supplier later. See how to protect your drawings and designs.
