Quality is often described as "fitness for purpose", but such a definition has no cost or processing considerations. A part produced using poor processes, which can be guaranteed only as the result of inspection, has no inherent quality A fuller definition is "reliability of function at lowest cost, resulting from good design and the use of capable processes". Throughout a product's life there must be regular reviews to reduce costs and to improve future designs. Small modifications can often produce further savings in both the manufacture of the component and on customers' assembly lines. Reviews should look closely at manufacturing data to seek areas where costs can be reduced, production simplified and quality and reliability increased. Keeping the above in mind, all of the parts are produced by GSS's sister factories which have designed and implemented a quality improvement program employing ISO/QS 9000. PPAP's documentations available. This program has effectively helped us reduce costs, increase efficiency, and strengthen our competitive position. In pursuit of quality products that meets or exceed every industry standard, GSS maintains a full complement of modern facilities for process control and quality assurance testing. If potentially incapable processes are to be used, design revisions should be considered. Designs should then be passed through FMEA for confirmation and control / monitoring points generated. The platform for quality is now established. Complete lot traceability and test data is fully documented and available. Total quality is guaranteed. Type of standard test carried out includes: 1. Curing Characteristics of Rubber Compound. 2. Assessment of Carbon Dispersion in Rubber Compound. 3. Tensile Strength, Tensile Modulus and Percentage of Elongation. 4. Hardness. 5. Compression Set. 6. Specific Gravity. 7. Percentage of Retraction. 8. Outgassing and Total Mass Loss - Ageing Test.
