Quality Assurance of Roll Forming Processes
At OMCO, superior quality is everyone’s responsibility founded from establishing a geographically diverse manufacturing presence, employing the industry’s best engineering staff, and incorporating a wide range of value-added manufacturing operations.
Quality products begin with a detailed review of a product print and its associated requirements. Next, robust engineering designs are generated to produce the tooling necessary to manufacture the part to its defined specifications. Those designs are then transformed into reliable and repeatable manufacturing operations and procedures.
Finally, our employees’ desire to consistently deliver the best possible part is crucial to achieving our ultimate quality objective … highly satisfied customers with superior quality of product delivered to them every day.
OMCO’s management system has been certified to ISO 9001, and our quality team is committed to driving every continuous improvement process in order to achieve the highest level of quality possible. Tools utilized to manage, monitor, and direct our continuous improvement efforts include:
- Statistical Process Control (SPC)
- Pre-Production Approval Process (PPAP)
- Failure Mode and Effect Analysis (Processes)
- Six Sigma
- Continuously Review and Update Standard Operating Procedures (SOP)
- On-going Operator Training
