Keys of quality assurance
control
1：Craftsmanship of
staff
Products
of high quality is bestowed by highly qualified and
professional staff. Our company trains the new staff
differently in allusion to different requirements of positions
before getting down to working. They can only start work after
having passed the assessment. Furthermore, we trained the
staff periodically so as to improve their professional
operation level.
2：Equipment and
craftwork
Advanced equipment is the foundation
of satisfying the requirement of realizing excellent craftwork
design.  Under this principle and based on the
advanced pipe manufacturing experience of the foreign
countries, our company researched and explored Coldfroming
Equipment,which adopts the PLC programmed control
system、Catting Machine、Heat treatment furnace, all of which
are the first class equipment for manufacturing pipes and
special frock mould by ourselves. We realized completely
automatic control during the whole producing process, and
avoid the influence of artificial factors to the quality of
the products.
Therefore, our company enjoys a high
reputation for the high precision of size, the uniformity of
the wall thickness of the pipes, and the excellence of 100%
solid-melt disposal.
3：Quality control of the
raw materials 
Our out-sourcing raw materials come
from the qualified suppliers after being strictly audited.
After arriving at our factory, except for inspection on the
size and Facing and chemical, all the raw material has to be
qualitatively examined and has to be quantificational spectrum
examined. It is until the examining results meets the standard
of our material inspection and the inspection report provided
by the supplier, that will we use the materials. After that,we
will input all the inspection data into our computer for
better management.
4：Control of the producing
process
quality control during the
producing process is one of the most important tache of
guaranteeing the quality of the products. In order to make
sure that the quality of every product is under control, our
company adopts the means of combining 100% self-inspection by
the worker and sample inspection by the professional QC. We
set up quality control reference point. The products of the
key working procedure will have to be examined by professional
QC before entering into the next working procedure. We
separate the deficient products and analyze the causes. Then
we put forward amending suggestions and dispose those
deficient products.
5：Inspection of finished
products
In order to assure the promise of “no deficient products will
leave our factory”, we established the system of complete
inspection equipment, advanced inspection measures,
professional QC, and quality inspection under the direct
management of the general-manager. The inspection center is
only responsible to the general-manger and functions
independently. So the justness and objectivity is guaranteed.
The inspection center functions strictly according to the
leaving-factory inspection standard of the products and the
standard of sampling. Unqualified products will never leave
our factory. |
