Cook-Leitch Inc. has proudly provided the technical sales, account development and program management role for ESA since 1984.

Engineering & Technical Support—The ESA’ Intangible!

  • ESA is an engineering-driven Powder Metal company.

  • We offer our customers prompt part design assistance.

  • We take into account the overall assembly design and the application of the P/M component.

  • ESA can offer P/M material recommendations based upon the part application.

  • ESA has (4) seats of 2020 SolidWorks.

  • ESA designs all Powder Metal (P/M) tooling in-house………..

    • Thus, we have complete understanding of the long-term maintenance of the tooling.

    • We are committed to maintain your tooling for the “life of the program".

Speed to Market: Our Commitment to YOU!

  • ESA is very responsive to customer’s RFQ demands.

  • ESA offers part design and assembly design support.

  • Very disciplined Advanced Product Quality Planning (APQP) system.  

  • Again, we understand the part application and function of our customer's assembly.

  • Tool design, tool build and PPAP submission ranges from 5-weeks to 8-weeks.

​

​ Manufacturing Capabilities:

  • (82) molding presses

    • T​onnage range is 4 ton to 300 ton (approx. 9 sq. inches)​​

  • (24) sintering ovens
    • High-temperature sintering​
    • Air-hardened sintering capabilities

  • ​(16) sizing presses--High-speed sizing of bearings (straight-walls, flange, etc.), spacers, bushings, etc.

  • Copper Infiltrating and other high-strength materials for your application.

  • Warm compaction capabilities for higher strength, higher density is set-up on 75% of our molding presses. 

  • Note: The Powder Metal (P/M) Industry is committed to "Green Technology".  See below video, "The Sustainability Continuum".

​ESA is Quality-Oriented:

​

  • ESA is ISO9001:2015-registered.  We have an excellent quality performance history. 

  • The key to ESA’s quality is…….

    • Understanding the part application and function, and design a P/M part for manufacturability.

    • Secondly, ESA has a very disciplined approach in designing high-quality, robust tools.

  • ESA is diligent in our preventative maintenance of tooling—We protect our customer’s investment!!

  • ESA monitors our quality throughout the molding, sintering, secondary processing (i.e. heat treat, machining, plating, etc.).

  • ESA specializes in Safety Critical applications, and we have a full QA Lab, including mechanical break-testing equipment for comparative yield strength, elongation, etc.

  • ESA also features a 5,000 sq. ft. Non-Destructive Testing (NDT) department—

    • We can high-speed 100% inspect P/M parts via

      • Auto Vision Systems ​

      • Resonant (Sound) Inspection Systems

      • Or, incorporate both NDT' 100% inspection techniques for your safety critical P/M components.
