Mini portable radiator/radiator fan/electric radiator
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.
 
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.
 
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.
 
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.
 
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.
 
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 radiators.
