Product Description

Copper spout 
Definition & Function:
A copper nozzle is usually a small, component made of copper material. In different application scenarios, it serves to direct the flow of substances such as fluids, gases or powders. For example, in the welding process, copper nozzles guide the flow of shielding gas or solder; in spraying equipment, copper nozzles are used to control the spray pattern of paint.
Material characteristics:
Copper has good thermal and electrical conductivity, which makes copper nozzles perform well in situations where rapid heat dissipation or conductivity is required. At the same time, copper is relatively soft and easy to process into various shapes and sizes to meet different needs.
Machining process:
Casting: Copper is melted and injected into a mold and cooled to obtain a copper nozzle blank. This method is suitable for mass production, but there may be some minor imperfections that require subsequent processing.
Machining: Copper blanks are machined by turning, milling, drilling and other processes to obtain precise dimensions and shapes. For example, the outer circle and inner hole of copper nozzle can be turned by using lathe, and special shaped ports can be processed by milling machine.
Stamping: For some copper nozzles with simple shapes, the stamping process can be used to stamp the copper sheet into the desired shape using a mold. This method has high production efficiency and low cost.
II. Copper bushing
Definition and function:
Copper bushing is a kind of set in the shaft parts on the cylindrical parts, mainly play a role in reducing friction, support the rotation of the shaft as well as the protection of the shaft and the parts with which the role of the parts. It can withstand a certain load, while reducing the wear between the shaft and other parts.
Material Advantage:
Copper bushing is usually made of high-purity copper material, which has good wear resistance, corrosion resistance and self-lubrication. In some occasions where there is no external lubrication, the characteristics of the copper sleeve itself can ensure its stable operation for a long time.
Processing technology:
Centrifugal casting: copper liquid is injected into a high-speed rotating mold, using centrifugal force to make the copper liquid uniformly distributed in the inner wall of the mold, after cooling to form a copper bushing blank. This method of production of copper bushings dense organization, high strength.
Powder metallurgy: Copper powder and other additives are mixed and then made into copper bushing by pressing and sintering process. Powder metallurgy copper bushing can be adjusted according to the needs of the composition and properties, suitable for some special applications.
Machining: The cast or sintered copper bushing blanks are processed by turning, grinding, etc. to obtain accurate dimensions and surface finish. For example, the inner diameter of the copper bushing can be made to reach high precision by grinding to ensure the matching precision with the shaft.
