WINCA strictly according to ISO-9000 standard for quality control of products, from raw materials into the plant to the factory and in all stages of the production process are implemented "three inspections" (Self inspection, mutual inspection, special inspection). Quality prevention, focused on the following quality forming and process control.

一、Control of raw materials and purchased components

1、Car Navigator product quality depends to some extent on the quality of raw materials and auxiliary parts quality. Therefore, our company developed the supplier quality evaluation procedures and the control procedures on procurement of materials, preferred to elect a qualified supplier, used for the strict control of raw materials and auxiliary parts.

For raw materials and outsourcing set of quality evaluation of parts suppliers, purchased by the manufacturing Department Group apply QA organizations purchase, design and Technology Department staff review group, to evaluate the supplier's quality, based on the evaluation results to determine whether to issue qualified supplier certificate to qualified supplier upon approval by the General Manager, Included in the list of qualified suppliers. Directory of purchasing department must purchase a specified range.

2、On material procurement, procurement department to develop materials specifications to guide the inspectors work, and again after a group of components used in the product part of the performance tests. Through a variety of means of inspection, testing, substandard materials cannot enter into the factory, which laid the groundwork for the production of quality products.

二、Quality control in the production process

1、In the production process, the important processes are certified, quality control of product manufacturing process (QC). Implementation of " Create positions a person, The responsibility comes to the person, the reward and punishment is clear " management system, enhance the quality awareness of each employee to ensure manufacturing quality of each procedure.

2、In the process of production, quality inspection and implementation of "three by" and "three inspections". Three by, that by drawings, and by standard, and by process procedures, not only requirements operation who manufacturing quality reached standard and the drawings requirements, and operation process, operation method are to by process procedures; three inspections, that " Self inspection, mutual inspection, special inspection ", warranty designed check process in the, judge not qualified of products or component, strictly by not qualified products program for processing.

3、In order to ensure the quality of products, from raw materials to form the final product throughout the process, the factors affecting the quality monitoring, measurement, and control. Companies to set up special inspection personnel, inspection personnel inspection according to inspection instructions. Inspector in the inspection instruction based on qualified or unqualified conclusions and identified qualified or unqualified on the hanging. Inspectors give qualified conclusions and after hang up the qualified identifier, to go the next step, next step after seeing qualified identifier can be accepted, use. No qualified conclusion or a qualified identifier, products cannot be carried forward to the following process.

4、In order to prevent the use of nonconforming products, the company formulated the relevant procedures, the nonconforming product identification, identification, isolation, and assessment and treatment are provided in detail, and in order to prevent substandard goods and prevent the occurrence of potential nonconforming, the company developed a program of corrective and preventive measures, required the unqualified reason analysis And the cause, by the responsible departments to develop corrective measures carried out by the quality assurance Department supervision, assessment.

Companies strictly enforce the "five no" system, that is: "the unqualified raw material not feeding, unqualified blank no processing, substandard parts not assembled, manufactured substandard products are not allowed, the unqualified product yield and output value is not calculated."

三、Final inspection

1、Quality of final product to use test data to evaluate, in order to increase the accuracy of the data, we used to test main test equipment, instrumentation, selection of domestic and foreign advanced equipment with international advanced detection level.

2、Product testing the validity of data depends on the reliable instruments of guarantee, company developed the program files of the control procedure of measurement and monitoring equipment to test the main instruments, regular weeks of strict inspection system, using each instrument, meters can ensure its effective period, so as to ensure their full effectiveness.

3、Product test is checked after the test, the company strictly according to national standard and IEC standard. Company's personnel receive specialized training, certificates, test one-third of the personnel are test engineers, test level in secondary education or above, so in terms of technical quality, fully meet the needs of all kinds of products testing.

4、In order to ensure the successful transformers on site Assembly, after the test, Complete all the parts and design, sales, Assembly, inspection, acceptance, all products up drawings and standards requirements, removable, and shipped.
