Engineering & Manufacturing

“Value” Engineering

Our experienced engineering resources ensure your product will be manufactured precisely all the way through to completion. C4 Manufacturing and Applications Engineers begin with a detailed examination of your entire project, upfront. They analyze drawings and specifications for manufacturability and determine where efficiencies might be gained to save you time and money. We utilize an array of world‐class CAD and CAM system software to accept and process your initial concepts and drawings.

Our services also include design assistance, material selection, weld‐distortion shrinkage calculations, and application of proper weld symbols.

 Machining & Manufacturing

The vertical integration of our engineering services with C4’s precision manufacturing services helps prevent time‐wasting communication stop points for clarifications and can dramatically reduce wait times between project steps. We have a well‐equipped fabrication and machining shop able to handle part production for a wide variety of pre‐ and post‐welding processes.

C4’s fabrication and machining services rival dedicated shops in the abilities and scope of services. We can eliminate your need for separate specialized vendors – and the time spent on shipments – with both critical‐grade welding capabilities and precision machining and fabrication services under one roof.

Large Part CNC Machining

Increased customer demand for larger and larger welded and machined structures led C4 to bring world-class large part precision machining capabilities to our shop floor with the installation of a SNK RB6M Double Column Multi-Center.

SNK has been manufacturing Double Column Machining Centers for over 50 years, with over 5,000 units installed world-wide. RB-M Series Machining Centers deliver productive 5-face, single set-up machining. The rigid double column design and construction assures peak precision and excellent work envelope access. This machine has both an automatic tool changer and right-angle attachment changer. In addition to X,Y & Z axes, a CNC-controlled 4th axis (W) expands machining capability and provides exceptional rigidity for rigorous cutting conditions. The generous quill stroke (Z) allows exceptional access to cavities simplifying deep hole cutting.

The addition of this machine allows C4 to service our customer’s needs better with shorter lead times, increased project control, and fewer associated logistics challenges. C4 has acquired highly-experienced large part programmers/machinists dedicated to supporting this new mill.

ISO 9001:2015 Certified Quality Systems

AWS Certified Weld Inspectors

Quality is the highest priority for us. This is demonstrated by having AWS Certified Weld Inspectors (CWI) on staff. The benefits of doing so include the following: the ability to conduct in-process inspections both during welding cycles and at critical control points; and the opportunity to document findings throughout the process. This way, we can provide documentation at any point during the process to validate that the product is being manufactured to the drawings and specifications you provided.  The end result is a proactive, well-managed program that ensures top-quality results, each and every time.

C4 can provide the following tests in-house:

  • Magnetic Particle (MT)
  • Liquid Penetrant (PT)
  • Ultrasonic Test (UT)
  • Visual Test (VT)
  • Functional, Hydro, and Proof Testing
