METAL FABRICATION & FORMING
METAL FORMING
Choctaw Defense Manufacturing Group (CDMG) can transform raw metal sheets or solid stock material into virtually any shape or form using a large array of precision, computer-controlled, metal-forming equipment.
Metal-forming equipment available at our manufacturing facilities includes:
CNC Press Brakes
CNC Shear
CNC Hydraulic Forming Press
Sheet Metal Roller
6.5KW Fiber Laser
CNC AMADA FORMING PRESS
CNC JOHNFORD VERTICAL MACHINING CENTER
CNC AMADA TURRET PUNCH
PRECISION CUTTING
Fiber laser, water jet, abrasive water jet and high-definition plasma cutting are proven processes in precision production. These systems can produce complex flat pattern parts from most materials, including extremely hard, reflective and non-conductive materials.
Metal, plastics, glass, ceramics, rubber, foam and engineered composites can be cut to a tolerance of +/- .005 inches.
CDMG uses fiber laser, water jet and HD plasma cutting as preliminary processes to other material fabrication, including milling, tube bending, precision sawing, turning, forming, wet and powder coat painting and welding.
Not only does this enhance the range of products offered, but it also expands upon our ability to deliver quality parts made to our customers’ specifications.
QUALITY ASSURANCE
Quality Assurance Staff
Our CDMG Quality Staff has over 75 years of combined experience in quality assurance and over 70 years of experience in dealing with military equipment contracts. This department staff has been directly responsible for all quality assurance checks and required testing on manufactured products.
Choctaw Defense Certification
Choctaw Defense holds ISO 9001:2015 and AS9100D certification through a third-party registrar. In addition to our quality assurance staff, the Defense Contract Management Agency (DCMA) has a Quality Assurance Representative (QAR) assigned to our production efforts. The DCMA QAR routinely performs process audits as well as source inspections if the contract requires “‘inspection at source.”
Quality Inspection Process
Throughout the manufacturing cycle, our QA team performs routine process audits as well as product inspections. Quality Assurance technicians verify operator performance, training and the use of the most current print revisions and product conformance in relation to the specifications detailed on the prints.
Choctaw quality assurance technicians will subject the first completed unit, or First Article (FA), to any requisite testing to ensure the FA meets any and all product specifications as detailed contractually. The customer will identify these specifications within a Statement of Work, Purchase Description or within the body of the contract itself by reference to external standards. The specifications may also come from various commercial or government specifications or standards. AWS welding standards would be an example of a set of specifications employed by Choctaw in its production efforts.
WELDING
Welding is a core proficiency of CDMG’s capabilities; we create and qualify weld procedures in-house as required to conform to customer contract requirements and to military or commercial specifications.
CERTIFICATIONS
Our welding staff includes both American Welding Society (AWS) Certified Welding Inspectors (CWIs) and Certified Welding Educators (CWEs). In addition, our welding personnel are certified in a variety of materials and welding processes and use fully qualified welding procedures.
TRAINING
Our Certified Welding Educator (CWE) trains and tests all of our welding staff about welding procedures developed to accommodate contractual stipulations. We send test plates to an independent (third-party) firm for examination. We maintain and track each welder’s testing and certification status. AWS accommodates separate requirements for welding under different circumstances.
CDMG welders pass specific AWS requirements prior to any work to be performed. Quality Assurance staff examine weldments throughout the manufacturing process at designated points to verify conformance of the effort through that particular production point.
