CWTW has formed a complete set of perfect quality control system in the designing and manufacturing of over 60 years and has started to carry out the system of Total Quality Control from 1980 and put into effect the series standard of ISO9000 “QUALITY MANAGEMENT AND QUALITY CNOTROL�?from 1992. Up to date CWTW has built the Quality Control System in accordance with the Chinese standard GB/T19001-ISO9001 “Quality Control Pattern of Quality System, Design, Development, Production, Installation and Service�?to ensure that the whole course from the contract judgment /examination to designing, to purchasing of material, to manufacturing, to sub-supplied parts, to packing and delivering as well as after-service achieves demand of “QUALITY FIRST and CUSTOMERS SUPREME�? CWTW has gained the ISO9001:1994 QUALITY SYSTEM CERTIFICATE�?awarded by China Quality Certification Center For Import And Export Commodities on Feb 1, 2000 and also passed the certification of ISO9001:2000 standard on Jan 28, 2003 and Mar 9, 2006.
According to the quality control system, the working/management duty of all the departments is as follows:
1. The “Quality Control Dept.�? led directly by the president, is in charge of the following works:
1.1 Organization, co-operation, checking and supervision of quality works in/inter-workshop/departments and supervision of quality works in/inter-workshop/depts
1.2 Assignment of control targets and compile of plans and control systems for different levels.
1.3 Organizing and supervising the execution of these plans by means of strict liability system.
1.4 Organizing quality training of the staffs/works in order to strengthen their quality senses.

2. The “Inspection Dept.�?is in charge of inspection works, which which are carried on through the whole process of manufacturing from the material purchase to assembled product, according to relevant standards and contract specifications. A quality certificate shall be issued to each produce the fore delivery. Advanced inspection methods, such as NDI are applied to main and key parts/components, by qualified inspectors. This dept. is responsible for not only routine inspections, but also performance tests when such tests are possible to be performed in the workshop.
