Features:
1.     Cutting: the tubes/pipes are cut
and molded by digital laser machine, to ensure the accuracy of
specifications. Other factories use the old manual cutting,
causing the error of the pipe size in the first step of size
processing, thus affecting the subsequent working procedure and
making size deviation of the products.
Â
2.     Holes punching: different hole
punching tooling are used on different diameter tube materials to
ensure the accuracy of subsequent process of products. Other
factories take hole-drilling way without forming a complete set of
grinding tools. It¡¯s very difficult for them to ensure accuracy
and unity of water holes.
Â
3.     Welding: all joint places are
welded automatically by machines.
Some other factories use simple welding equipment, even manual
welding. It¡¯s hard for them to guarantee the robustness and
standard unity of the welded parts.
Â
4.     Tolerance accurate adjustment:
after each unit of product is welded, the tolerance is checked and
accurately adjusted to ensure that all the specs are within the
required tolerance standard. Other factories products can¡¯t
guarantee product diagonal dimension and level up degree.
Â
5.     Pre-treatment: the
environmental-protection-accredited pretreatment of rust removal
and phosphoric treatment etc. guarantee the good finish of products
and their durability of usage. Some other factories simply use
sandblasting for derusting, however, the sandblasting process is
difficult to guarantee the rust removing effect of inner angles and
dead space of lapped welding products, so it brings hidden danger
to anti-rust of the products. There are some factories which use
old pretreatment process, such as phosphating. Their usage of
chemicals such as acid causes great harm to the environment.
Â
6.     Powder-coating: all products are
spray-painted with environmental-protection outdoor powder of
good-repute factory by electrostatic spray, ensuring the uniformity
of color level, processing craft, and exterior exquisiteness.The
large standard powder factory owns maturity powder processing
technology and superior quality and its price is higher than other
small powder plant, so not a few radiator factories only use the
powder of small factory and the poor quality of powder seriously
affects the exterior of the radiato
