Value Added Operations

The Finishing Touch

Few products are ready for shipment immediately after molding—products often require additional processes to prepare them for market. For some, it is necessary to provide a more finished and aesthetically pleasing look. For others, secondary operations improve part functionality. 

For companies looking to improve supply chain efficiency or consolidate vendors, Sterling's value-add operations make us a "one-stop shop."

Secondary Operations

Sterling possesses a wide array of finishing capabilities and excels at adding value through finishing and secondary operations including:

  • High-speed assembly automation
  • Decorating
  • Pad printing
  • Hot stamping
  • Sonic welding
  • Silicone dipping
  • Heat and sonic insertion
  • Over-molding (vertical and horizontal)
