Industrial parts made to your drawings — one-off or in series
Enteha Group makes industrial parts and assemblies to your drawings, one-off or in series, with partner workshops in Tehran and Isfahan, and carries out its own quality control before delivery: CNC machining, laser cutting, bending and rolling, welded structures in steel and 316 stainless, pressure vessels and enclosures, plastic injection moulds, and dimensional and weld inspection with GD&T.
Because we design and build machines ourselves, we do not just follow the drawing — we also think about how the parts fit together at assembly, so there are no surprises on assembly day. We work for clients across Iran, and quotes are free.

How we work
Send drawings or a sample
Drawings in any format, photos or a physical sample, plus the quantity you need.
Free quote
Review of the drawings, fabrication process and suitable material; usually within 1–2 weeks.
Drawing review for fabrication and assembly
Before fabrication, we check the drawings for manufacturability and for how the parts fit together.
Fabrication
Fabrication in partner workshops in Tehran and Isfahan, supervised by the group's manufacturing lead.
Quality control
Dimensional and weld inspection before delivery.
Delivery
Delivery of the parts or the assembled unit, with on-site installation where needed.

Why Enteha?
- One owner from design to assembly. Most outsourcing trouble starts when design, fabrication and assembly are in different hands and nobody sees the whole machine. At Enteha, the engineer who designs it stays with fabrication and assembly to the end.
- A core engineering team plus a partner network. Three mechanical engineers from Sharif University of Technology, IUST, K. N. Toosi and Tarbiat Modares University, working with industrial workshops and specialist engineers in analysis, quality control and consulting.
- A track record you can check. 80 postal sorting robots built for Iran Post, the first knee-prosthesis test rig of its kind in Iran, the Alborz Elite Prize and two Khwarizmi Youth Festival awards, and papers in Scientific Reports and the International Journal of Mechanical Sciences.
- Quality control before delivery. We carry out dimensional and weld inspection and functional testing ourselves before anything ships.
Industries we have worked for
- Medical and dental devices
- Postal and logistics
- Additive manufacturing (3D printing)
- Universities and research centres
- Service robotics

Frequently asked questions
Do you take one-off orders?
Yes. We take both one-off and series orders; the right quantity for series production depends on the job.
Which materials do you work with?
We choose the material of each part for its application — from steel and 316 stainless to aluminium, engineering plastics and composites. If the drawing specifies the material, we follow the drawing.
Do you make large parts and structures?
Yes. We have built structures of about 1–2 tonnes and can install them on site where needed.
How do you control quality?
Before delivery we carry out our own dimensional and weld inspection and check geometric tolerances (GD&T).
What if I have no drawings?
If you have a sample part, we reverse-engineer drawings from it. If you only have an idea or a description, we can do the design as well.
Is the quote free? How long does it take?
Yes, quotes are free. A quote usually takes one to two weeks, because our engineers review the job technically and consult the group's advisers before giving a price, so that the price and schedule we quote are realistic.
What do you need to get started? Which drawing formats do you accept?
Whatever you have is enough: 2D drawings or 3D models in any format (such as STEP, DWG, DXF, SolidWorks or PDF), photos, a hand sketch, or just a description of the job. If you have a physical sample but no drawings, we reverse-engineer the drawings from the sample.
What support do you give after delivery?
For machines we designed and built ourselves, we fix any faults for two months after delivery (separate from new requests from the client). A longer warranty, repairs and upgrades can be written into the contract however the client wants. If the design came from the client and we only did the fabrication, we still fix faults caused by the design, but that work is charged separately.
Do you only work in Tehran and Isfahan?
No. Our office and partner workshops are in Tehran and Isfahan, but we work for clients across Iran.
