Custom Interface is committed to delivering
what you need, when you need it, every time.

We are certified to both the stringent aerospace QMS AS9100-D quality management system as well as ISO9001.  We have never had a major non-conformity and there were no minor non-conformities found in 2020 because we are process driven and focused on continuous improvement.  We understand how the cost of quality impacts the bottom line. 


Quality begins with communication that leverages our experience.

Our technical sales staff and cross functional teams review each project with our clients to ensure we deliver exactly what’s needed. 


  • All communication is routed through an account manager assigned to you when you place your first order.  You can be assured of continuity and follow though. 


  • Our products have been successfully operating  in the highest risk environments for years.  We leverage lessons learned from these demanding projects to deliver excellence with every shipment that leaves our door. 

Quality depends on capability, capacity and expertise.

  • Manufacturing expertise and robust supply-chain management you can rely on.
