part randomly.
2) Process control to be carried out by Quality dept. through first pieces inspection,
random inspection every hour and last piece inspection; meanwhile, operators
have to do self-inspection and double checked by the next process. Final
products to be inspected randomly before going to the stock. Every order should
be again checked by Quality dept. before delivery.

PRODUCT INTRODUCTION
22. TWIN TUBE SHOCKS
All weather designed shock absorber oil remains nearly constant
viscosity
Oil is kept in and dirt out by a multi-lip seal, self-lubricant to prolong life
time
Less friction and longer life is the result of hard chromed, super finished
piston rod
Sintered rod guide to extend life of shocks
Seamless cylinder to reduce possibility of splitting
Sintered piston to add strength
Wear resistant Teflon piston ring to reduce friction and leakage
3-stage compression valve to assure fast recovery
3-stage rebound valve to generate different damping
upon different travel
Bore sizes from16mm to 50mm

32. Technology Center Introduction
Zhejiang Zhongxing Shock Absorber Manufacturing Co.
and Zhejiang Depeng Machinery Co., Ltd. are professional R
& D and manufacture of automotive shock absorbers medium-
sized enterprises. The company's technology center as the
group's R & D institutions, carrying the responsibility of
creating and developing business. Founded over 25
years,coagulating several generations of shock absorber R &
D personne's wisdom and emotional. And now she has
become the largest trade of shock absorber product research,
development, testing and inspection center in china.
Technology center is responsible fordeveloping all shock
absorber, modular and related parts to achieve the important
task of promoting the development of products basing on
technology innovation and development. Set up four
departments: design department, technology department, trial
production department and engineer department, which own
two tooling workshop, one prototype workshop, one
performance test laboratory and one durability test laboratory.
33. . Covering product development, testing, technology and
engineering complete organizational system.Product development
using CAD, PRO / E software.
Technology center own two engineers who have more than 30
years of professional shock absorbers and eight engineers who
have more than ten years experience. All the engineering staff
more than 80. Development and management basing on the
advanced management system PDM and ERP systems, effective
control of various development nodes.
Technology center developed more than 6000 kinds of the world's
currently mainstream models, and is growing at an annual rate of
