Client Overview – Sundaram

Fasteners Ltd (SFL)



Sundaram Fasteners Limited has grown into a global leader, manufacturing critical, high

precision components for the automotive, infrastructure, windmill and aviation sectors. Their

varied range of products encompasses fasteners, powertrain components, sintered metal parts, iron powder, cold extruded parts, radiator caps and wind energy components. They have won the trust of both OEM and aftermarket customers in highly competitive markets like India, China, Germany, USA, UK, Italy, France and Brazil.


SCM Issues

SFL implemented SAP ERP system to handle all their transaction. But it was not able to handle constraint based production planning and scheduling. This lead to problems as below:

  • Each plant had their own excel file to do planning. S&OP had to manually consolidate to get the expected dispatches.

  • Plan prepared on day 1 of the month becomes redundant on day 5 because of changes in customer schedules

  • Material requirement was checked manually before releasing the order to shop floor

  • Not able to get expected material shortage so that corrective action can be taken before shortage happens

  • No visibility to orders and hence dynamic batch creation for heat treatment was a nightmare

  • Unable to get the expected load on each of the resource based on pending orders

  • Unable to utilize the idle capacity of resources effectively

  • No visibility to schedule the subcontractors

Planvisage Solution
