In Design and Engineering Department. Grayhill(Shenzhen) is an OEM and ODM company mainly engaged in the design and production of CT machines, MRI machines, ultrasound machines and other medical equipment for medical equipment companies for Philips Medical, General Medical, Mindray Medical, Zoomlion Industry.* As the teamleader to track and coordinate the progress of each project to ensure that each project is completed on schedule for testing and into pilot production. * New product design, customer UI control panel design, mold confirmation, color difference control formulation. Debugging and testing, fixture and packaging design and testing.New product introduction. Assist in mass production of non-locally developed products and handle production issues.* Review supplier PPAP and complete customer parts certification according to AQPQ process. Coordinate with customers to confirm test standards.* Handle customer returns.While completing the product design of the customer, the problems in the customer's design were pointed out according to my experience. The customer did not adopt them, but it did have related problems in the subsequent trial production stage, and finally the FDA certification was completed by upgrading model. Another customer proposed unreasonable color difference requirements and coating test requirements, I asked him to correct it by experience, the design team from it didnt adopt my suggestion and caused the projects delayed finally admitted my opinions. These two customers are among the top three medical CT enterprises in the world.

As a product engineer in technical department, later as a superviser of the research and development department. Forem was a subsidiary facility of ALLEN, ANDREW, COMMSCOPE and TATFOOK respectively. Was famous in filters, combiner and splitters, TMA, antenna design and production. Its main customers are SIEMENS, LUCENT, AT&T, T-mobile, Alcatel.* Responsible for the preparation of new product introduction and process documents, tooling and fixture design, trouble shooting of the problems arising from the localization of the imported materials and technology, such as the imported materials` localization caused the process changes and test drifts, different machining method caused different deformation.* By PFMEA, guided the technicians to find the root causes of the products rework. Established a QIT research team to classify research results of technology issues. Trained the technicians, followed laboratory sample test, solved the questions from international customers. Audited and certificated suppliers, collaborated with suppliers on new materials and technological experiments and participated in the defination of relevant incoming acceptance criteria.* Led to establish the research and development flowchart of design

As research and development manager. Main productis plastic optical fiber and ralated products.* Met the requirements of various plastic optical fiber products from foreign customers, and was responsible for mold design, developing patented products, products` standardization.* Customer communication and to resolve technical issues. Classified design and production standards according to different customers. Made samples and passed tests based the time schedule.* Defined the assessment index of the project managers, established incentives to mobilize the enthusiasm of staffs.

The main product was the optical switch, isolator and optical amplifiers, and more.* Has worked in the pilot department, research and development department, as a process engineer and mechanical engineer, respectively in new product introduction process documents writing, improving production process, designing fixtures to improve assembling and test process. Finally achieved production method from one-piece hand-operated to pipeline operations, increased the production efficiency improvement about 30%. Improved jig reduced the product test time by a factor of 4 times.* Redesigning the product by PFMEA resulted product test pass rate increased from 70% to 97%.

which introduced the technology belongs Pilkington from United Kingdom, with a total investment of more than $ 83 million, was a major introduction project of Qingdao. * Participated in the company and was assigned to the batch plant introduce local Chinese equipment to replace the imported equipment, with the same production efficiency and saving cost about 2 million RMB.* As a batch plant leader and established debugging, inspection and maintenance of the equipment, dispathed the staffing and schedules, improved automatic weighing conveyor system, purification system and made substantial improvements to the production environment. Production promotion was about 20%.* Led a innovation team, upgraded of existing equipment to resolve the imported transport equipment which could cause accumulation of material for the cold weather in north China. Redesigned the electric viberating screen by using 2 layered screens to replace imported mesh, so that line down maintenance was extended from half amonth to half a year.
