The Goal– Throughout our history we at SINCERE TECH Plastics. have pursued continuous improvement in both quality and performance.Our quality policy is simple and clear: “Deliver Products Within Specification, On Time, Every Time.” We accomplish this through control of upstream process variables, inspection and testing, and verification of performance using documentation and statistical tools.

Inspection and Testing – Sincere Tech Plastics has thoroughly documented procedures for inspection and testing. They are tailored based on the requirements of the product in question. Products we produce are checked at
various times during the production process. Some checks are completed using boundary or attribute gages. Other products are tested for measurement using gages that can be traced to national standards. Tools such as attribute check sheets, X-bar and R charts, Gage R and R analysis, and CPk analysis are used to monitor the product and prove the capability of the process.


Documentation/Verification – We confirm our performance with documentation of many types ranging from process capability indices to on time delivery percentages. Records are kept to ensure that only product that has passed our inspections and tests is released for shipment. Statistics are used to analyze data and records are forwarded to the customer when required. Any product that does not pass inspection is controlled by procedures for handling non-conforming product. Lot tracking is maintained on all raw materials through the process. Raw material lots are linked to our finished goods lots for research should there be a problem or concern with a shipment.
