Quality Directive

S.A.R. Composite Shop has assembled a comprehensive Quality Assurance program that insures customer requirements are met. Once the customer's part has been developed, The Composite Shop implements ISO 9001 level processes that will produce a part consistently and to their quality expectation. S.A.R. Composite Shop does not "inspect" quality into their parts, but has implemented in-process controls and process improvements that keep the parts on track through the complete manufacturing cycle. Some of these ISO 9001 level processes include operator certification, precise process instructions, corrective action process, statistical process control, metrology (proper calibration of equipment), document control, and preventative maintenance.

The Highest Quality Products

S.A.R. Composite Shop engineering & manufacturing group has been producing volume production products since 1992. Rather than "inspect quality into part," we engineer quality into the product. Statistical process control (SPC) points are strategically placed at various points in our fabrication processes. These SPC points monitor the "health" of our fabrication processes, identifying potential out of spec parts before they are completely fabricated. Our goal continues to be to produce high quality, tight tolerance products at an affordable price.

Using our filament winding fabrication process we have consistently maintained the specifications, shown below in the Fabrication Specification Table on our 4 inch square carbon/epoxy tubes.

Resin transfer molding (RTM) fabrication offers even tighter dimensional tolerances on the products we manufacturer.

Testing is important in our production of high quality products. We utilize a variety of testing options.
