A Promech Industries Company.

Promech manufacturing facility in Coimbatore
Our home in Coimbatore. Where MARK machines take shape.

From a single grain
to a complete process.

Promech Industries Private Limited brings machinery, sensing and electronic controls together in Coimbatore, India.

Established in 2005, our company designs, develops and manufactures MARK equipment for food processors and industrial applications. Optical colour sorters are part of a wider range that includes rice and dal milling, grading and insect removal, textile machinery and custom projects.

Our work starts with what you process and what you need to separate. From RGB pixel processing and image processing to belt sorting, each platform provides a different starting point for your material.

What guides our work.

Practical engineering

Machine design starts with the processing requirement. Our background in sensing and electronic controls helps us develop equipment around the material, installation and intended operation.

Quality throughout the build

Checks begin with components and continue through assembly. Each machine is tested against the customer’s requirements before final inspection and dispatch.

Support beyond installation

Our central service team helps customers find technical information and arrange assistance. Contact MARK with the model and location so we can coordinate support.

From requirements to readiness.

  1. Understand the material

    Discuss the product, defects to separate and the production requirements.

  2. Build and inspect

    Components and assemblies are checked through the manufacturing process.

  3. Configure and test

    Machine programs and settings are prepared for the agreed application.

  4. Check and dispatch

    Final inspection precedes packing, dispatch and the next installation step.
