We produce METALLECA® blower impellers that are matched with blower housings. All of them are required by the same customers. The materials used for blower impeller in the market are no longer limited to the steel or pig iron. Our production of blower impeller is made aluminum alloy and common carbon steel, since the characteristic of lightweight stainless steel and aluminum alloy is gradually used in current. Blowers are widely used for ventilation, dust exhaust and cooling in factories, mines, tunnels, cooling towers, vehicles, ships, and buildings. For example, ventilation and induced air for boilers and industrial furnaces; cooling and ventilation in air conditioning and household appliances; grain drying and selection; wind tunnel and hovercraft Inflation & propulsion, etc. The blower housing is asked to show high specifications in appearance, performance, assembly and other aspects, regardless of the general requirement. There is a rigorous production process from blank to machining process. In the casting process, we focus on mold design, pouring temperature, aluminum and molten steel clarity (exhaust gas, slag removal), pouring speed, blank surface treatment. In the manufacturing process, we also consider the rationality and stability of fixture design, the machining precision of critical dimensions, the rationality of turnover (method, protection, etc.), and the standard packaging and pallet methods to the final shipment.
