fan casting cover Manufacturers

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.

Forging Process is one of the two components of forging (forging and stamping), in which forging machine is used to press metal billet to produce plastic deformation and Electric Power Fittings so as to obtain forging with certain mechanical properties, shape and size.
According to the way the blank moves, forging can be divided into free forging, upsetting, extrusion, die forging, closed die forging, closed heading forging. 1.Free forging. Use the impact force or pressure to deform the metal between the upper and lower iron (anvil block) to obtain the required forgings, mainly manual forging and mechanical forging two kinds.
2.Die forging. Die forging is divided into open die forging and closed die forging. The metal blank is obtained by compression deformation in the forging die bore of a certain shape, which can be divided into cold heading, roll forging, radial forging and extrusion, etc.
3, closed die forging and closed heading forging because there is no flying edge, the utilization rate of materials is high. It is possible to finish complex forgings with one or several processes. Since there is no flying edge, the forgings have less force area and less load required. However, it should be noted that the blank can not be completely restricted, so it is necessary to strictly control the volume of the blank, control the relative position of the forging die and measure the forging die, and try to reduce the wear of the forging die.

The METALLECA® Medical Device Accessories need high quality requirements for materials, surfaces and dimensions. Chinese proverb: a workman must first sharpen his tools if he is to do his work well. With the rapid development of medical device technology, the demand for medical device precision stamping parts is increasing. At the same time, the technical requirements are getting higher, and the applications are getting wider. Basically, stamping parts appearance has to zero defects. For this reason, a standardized manufacturing process to ensure quality is necessary. We focus on the selection of raw materials, mold requirements (design, material selection, surface cleanliness, dimensional accuracy, service life), the precision accuracy of stamping equipment, production efficiency, protective turnaround, post processing, surface treatment, packaging methods, etc.

METALLECA® Shell of Gas Cutting Machine are mainly used in gas cutting machine and laser beam cutting machine. Cutting machines are widely used in various industries, especially in modern innovation manufacturing that accelerates market demand. For this reason, the demand of cutting machine related parts and components has gradually increase.

The METALLECA® Door and window accessories include door control hardware, high-performance household hardware, wooden interior door hardware (plastic, aluminum alloy), window hardware, special types window hardware, sealing strip for building doors and windows, sealing top for building doors and windows, sealant for building doors and windows, ventilator. Since the market demand is increasing, the technical requirements, including intelligence and convenience, are getting higher, and the applications are getting wider. The Door and window accessories need high quality requirements for materials, surfaces and dimensions. Basically, hardware parts appearance has to zero defects. For this reason, a standardized manufacturing process to ensure quality is necessary. We focus on the selection of raw materials, mold requirements (design, material selection, surface cleanliness, dimensional accuracy, service life), the precision accuracy of production equipment, production efficiency, protective turnaround, post processing, surface treatment, packaging methods, etc.

Our company is an OEM/ODM supplier. Our METALLECA® Body housing and fitting joints of the production can be customized according to requirement of domestic and foreign customers. Production would follow customer’s specific requirements (assembly, performance, life, corrosion resistance, etc.) to select the appropriate processes and materials (mainly used casting aluminum alloy). Otherwise, the production and processing are based on the customer specification. We specialize in producing unpatented products and do not have our own brand. At present, we supply for supporting machinery and equipment to domestic and foreign customers only. We look forward to more inquiries and cooperation with new customers to become long-term partnership.
