GROWEL conceptualizes, designs, manufactures, supplies, and installs top of the line BARREL plating plants to suit various processes.

Barrel Plating is widely employed for bulk processing of small to medium sized components. The finishing process consists of components being placed in an apparatus called the Barrel. The barrel then passes through different chemical baths to complete the surface finishing process. These barrels consist of an electrical contact called the dangler which helps in passing DC current.

The selection of articles for barrel plating is limited by their size, shape, and weight. The Barrels are usually constructed using a non-conductive material. The barrel body has perforations which helps to attain a uniform finish of components.

Our plants are highly customizable depending on the customers requirement.


Barrel plating plants are beneficial for components that are small to medium sized and not very complex in construction. Fasteners, hardware, and electrical components are good examples of components that can be processed in barrels.


Suitable for below mentioned processes:


  • Diverse experience – Supplying plating lines since 1965, 800+ plants commissioned.
  • One stop solution – for all spares, consumables, and chemical requirements.
  • ISO 9001:2015 certified.

Automation is greatly preferred in bulk plating operations, predominantly for the following reasons:

    • Consistency
    • Reduction in labour costs
    • Elimination of human error
    • Reduced operational costs
    • Regulated inputs
    • Effective control for production
    • Versatility and Traceability

Automation Features:

  • Load as you Like
  • Automatic current and temperature control as per process requirement
  • Auto level and conductivity control
  • Auto dosing as per ampere-hour consumption/as per area processed
  • Production and event/alarm data recording
  • Online process monitoring
  • Event warning by SMS/Email
  • Voice Alarm
  • Bar Scanner for parts identification

Data Logging (SCADA) is an integral part of automation and has become a necessary tool for all plating plants. Growel’s sophisticated SCADA system with enhanced features are supplied with all its surface finishing plants. Data Logging helps in:

  • Online monitoring of status of Material Handling, Tanks and Equipment
  • Generating an immediate alarm in case of abnormalities in the process conditions
  • Accurate control of process parameters like temperature, current etc
  • Generation of reports for Day/Shift/Load wise production
  • Recording of all errors and abnormalities
  • Unlimited LAN access for control and monitoring of plant with multilevel password protection
  • Generation of Trend screens for all process parameters in real time
  • Maintaining alertness for all predefined mechanical, electrical, and chemical parameters
