Who we are

Three decades of quality, on-time delivery and frugal manufacturing.

SKS Accessories is a manufacturing firm based in Coimbatore, India. The firm started out producing pumps and motors and has since diversified into hand wheel actuator assemblies and precision valve components, operating two units across the city.

130 highly skilled personnel — with cumulative experience of more than 100 years — work across both units. SKS counts some of the largest valve manufacturers in the world among its customers, including several Fortune 500 companies, and has been awarded self-certified quality supplier status by one of them.

The organisation is ISO 9001:2015 certified, and its pump range carries CE / Low Voltage Directive compliance. SKS also supports the education and medical expenses of its staff, and funds education for the needy through a family trust.

02 / CAPABILITIES
Four reasons customers stay for decades

What SKS actually does differently

Each capability below is backed by a live case study from a Fortune 500 customer relationship — not a claim, a result.

01

Art to Part

  • Process engineering & tooling development
  • Prototyping and testing
  • Sourcing and supplier development
  • Precision welding, machining and assembly
  • Euro-palletization for export
Case study — Declutchable Actuator Assembly Built a 45-component gearbox assembly from scratch for a Fortune 500 client — a phosphor bronze worm wheel fused to a worm shaft, engaging over 180°. Passed the client's long endurance test on the first supplied batch.
02

Frugal Process Engineering

  • Value engineering without performance loss
  • Material and process substitution
  • Design-for-manufacture feedback to customers
Case study — Hand Wheel Actuator Assembly Replaced a cast wheel with a precision-welded sheet metal tube wheel for a Fortune 500 valve manufacturer: 40% cost reduction, no change in performance or quality. SKS is now the single global supplier.
03

Precision & Complex Machining

  • Turned components to 0.02 mm
  • Milled components within 0.08 mm
  • Cylindrical grinding, Ra 0.08, up to 800 mm length
  • Acme thread machining
Case study — Actuator Valve Stems Converted a thread-rolled, without-centre drawing to a with-centre design — enabling manufacture on CNC and grinding equipment instead of expensive thread-rolling machines. 50% capital & tool cost savings for the client.
04

Complete Sub-Assemblies

  • In-house machining plus an approved vendor network
  • Heat treatment, plating and painting coordinated end-to-end
  • Single-source delivery of finished assemblies
Case study — Side Mounted Hand Wheel Assemblies Sourced and machined 96 components in five materials, coordinated outside heat treatment, plating and painting, and assembled two complete actuator sub-assemblies in-house — now the single-source manufacturer for this client's worldwide requirement.
