ere at SFE, we understand that the acquisition of modern process lines can be a high capital investment. We offer a design and consultation service to upgrade existing plant that may be suitable for modification and is often nearing the end of its usability.



urface Finishing Engineering Ltd (SFE) supply a wide range of automatic process plant systems. Our engineers have experience of automatic process lines from 0.5m wide for Formula 1 parts up to 18m wide for aircraft wing components.





Fume extraction is an important feature of any chemical process plant. With an efficient fume extraction system the workplace is transformed into a clean and pleasant working environment in comparison to warm and humid process shops of the past.

We focus on plant and equipment being engineered for the 21st Century; equipment is robust and importantly, careful attention is given to the aesthetics of the plant.

Features implemented to Improve aesthetic appearance include:

  • Cladding around or attached to the equipment
  • Neatness of equipment layout
  • Materials being resistant to the chemicals and easy to clean
  • Quality and appearance of the fabrications and overall construction of the plant

Equipment Basics

  • Designed for minimal maintenance
  • Equipment is easy to keep clean
  • Transporter motors are high quality, requiring minimal inspections
  • Lifting is via plastic webbing belts - no need to lubricate and no corrosion
  • Transporter designed to ensure maintenance is accessible and safe to carry out
  • Equal priority given to access for maintenance as well as operator access

Automation of the Process Line Systems

  • Controlled via a PLC and computer HMI
  • Software systems are purposely designed for the surface finishing industry
  • Numerous features including traceability up to NADCAP standard and allows users to input and interrogate information to any level required
  • System can be interfaced with the clients’ network allowing remote interrogation and can be connected for text and SMS messaging
  • Inputting new process sequences are simple menu systems
  • Parts are stored in a library which include a photograph of the part of how it should be mounted on to jigs
  • Barcode entry is also a common feature to eliminate human error
  • CCTV monitoring offered to reduce the need for personnel to carry out physical inspection

The Future of Automatic Process Lines

  • Automatic transporter process lines have been around for 50 years however SFE have been moving things further with automation of processes only previously carried out manually
  • Sophisticated analysis equipment and automatic dosing maintain chemistry in equilibrium
  • Ensures consistency of processing and process specification compliance
    • Part rotation can be implemented
    • Automatic making and breaking electrical contacts and siphoning of liquids
    • Automated emptying and filling systems, eliminating the need for transporting hazardous chemicals around site and stopping the dangerous practice of manually adding chemicals into the tanks

Good Engineering

  • Good engineering is a top priority for SFE
  • Simplicity of design and eliminating unnecessary complication whilst at the same time considering equipment longevity has led to numerous improvements
  • Continuing value analysis in the design allows for significant improvements whilst at the same time reduces maintenance and risk of failures
    leading to a reduction in costs thus increasing value to our customers.
