CAD/CAM used in
Quality Control

� Virtual Testing: Modern computer aided design and manufacturing software systems (CAD/CAM) have voluminous data on material specifications and behaviors (such as plastic shrinkage rates or the heat tolerance of various grades of molding steel), which can be used to simulate the molding processes and �virtually test� a product to identify potential problems in design, construction and/or materials before the first cut is made for the actual mold.

� Precision Measuring: To implement quality control, China Array uses the three most prominent precision measuring systems: CMM (coordinate measuring machine), optical and laser. As a mold is machined and polished, first by the CNC machining center and later with more precision by the EDM machining center, it will be repeatedly measured to insure complete accuracy.

� Sampling: When a mold is complete, a test run yields preliminary samples for evaluation, which will provide information as to any possible modifications to the mold. As important as the dimensional integrity of the part, which can be determined through precision measuring, will be lab tests of the product in the US to determine if there are any signs of stress or weaknesses in the part due to the injection molding process or the product�s design that may need to be changed to eliminate stress points etc. If such processing problems are found the mold may be altered (increased gate size, additional cooling channels etc.) or the process altered (temperature, cycle time etc.). After this evaluation and adjustments to the mold and/or the process, another batch of samples will be run and sent to the customer for approval.

� Pre & Post Molding Sampling: Prior to molding, resin samples will be set aside, dated and labeled to track materials with the appropriate production run. First and last samples of finished goods produced will also be inventoried.

� Field monitoring: Once products are in the field, the QC function will shift to the applications engineers, who will monitor the performance of a product over time and make recommendations for future improvements. The quality control process outlined above combined with customer feedback at each step maximizes on time deliveries of defect free products.
