Enteha Group

Industrial robots, custom machinery and automation — designed and built by one team.

Our core team of experienced mechanical engineers from Sharif, IUST, K. N. Toosi and Tarbiat Modares universities works with a network of partner workshops and specialists — taking each project from concept design through fabrication, quality control and commissioning.

About the group

Enteha Group designs and builds custom industrial machines, robots and equipment. At its core are three experienced mechanical engineers, working with a wide network of collaborators — from industrial workshops to specialist engineers in analysis, quality control and consulting. On every project, each part of the work goes to the people best qualified for it, across the whole chain: concept and detailed design, engineering analysis, fabrication and assembly, quality control and commissioning.

Our members' track record includes 80 postal sorting robots built for Iran Post and a third-generation design produced as a 200-unit series, the first knee-prosthesis test rig of its kind in Iran, five industrial 3D printers, and awards including the Alborz Elite Prize and two second places at the Khwarizmi Youth Festival.

Our backgrounds complement each other: machine and robot design, mechatronics and automation; manufacturing, composites and quality control; and mechanism design, control and medical robotics. Between us we hold degrees from four of Iran's leading technical universities.

Our work has been recognised by the Alborz Elite Prize, the Khwarizmi Youth Festival, the Iran Industrial Design Festival and Sharif Science and Technology Park, and published in Scientific Reports and the International Journal of Mechanical Sciences.

Services

What we do

Three service lines, each with real projects and a page of details and FAQs.

Custom industrial machines & robots

A machine built for your process — from requirements and concept design to fabrication, assembly and commissioning.

  • Special-purpose machines and test rigs
  • Industrial, service and mobile robots
  • Mechanism design and engineering analysis (FEA)
  • CNC machines and industrial 3D printers

Production line automation

Automating the manual and semi-automatic steps of your line: control design, PLC programming, HMI and integration with existing equipment.

  • PLC programming (Delta, Siemens) and HMI
  • Motion control with servo and stepper drives
  • Sensors, weighing and measurement systems
  • Electrical and control cabinets
  • Production line and assembly station design

Industrial parts manufacturing — Tehran & Isfahan

Parts and assemblies made to your drawings, one-off or in series, with our 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
  • Dimensional and weld inspection, GD&T
Clips

Hassle-free outsourcing

2026

Every part arrives and each one looks right, yet on assembly day they don't fit together — because design, fabrication and assembly were in different hands and nobody saw the whole machine. At Enteha, the person who designs it stays with fabrication and assembly to the end: from special-purpose machines and production line automation to parts in series.

Team

The core team

Each project is led by the core member whose field it falls in; partner workshops and specialist engineers join for fabrication, analysis and quality control.
