The composition of a plastic extruder is mainly composed of an extrusion system, a transmission system and a heating and cooling system. So how do these systems work together? What is the working prin...
Screw fasteners are the most widely used mechanical basic parts and are in great demand. Surface treatment is the process of forming a covering layer on the surface of the workpiece through a certain ...
Electrophoresis has been increasingly widely used in various fields such as analytical chemistry, biochemistry, clinical chemistry, toxicology, pharmacology, immunology, microbiology, and food chemist...
There are many types of electro-galvanizing. But from the pH value of the galvanizing bath, there are two main categories: alkaline zinc plating and acid zinc plating. (1) Alkaline zinc plating The al...
With the continuous research and development of new technologies, “3D printing” has become more and more widely used, such as industrial design, dental and medical industries, construction...
Aluminum alloy die castings generally use sand molds or metal molds to pour the heated liquid aluminum or aluminum alloy into the mold cavity, and the obtained aluminum parts or aluminum alloy parts o...
A 3D printer is a kind of rapid prototyping technology. It is based on a digital model file, using powdered metal or plastic and other bondable materials to construct objects by layer-by-layer printin...
Galvanized steel sheet is to prevent corrosion on the surface of the steel sheet and prolong its service life. The surface of the steel sheet is coated with a layer of metal zinc. This kind of galvani...
It is the process of using electrolysis to attach a metal film to the surface of metal or other materials to prevent metal oxidation (such as rust) and improve wear resistance, conductivity, light ref...
The polishing machine equipment is a kind of electric tool. The polishing machine equipment is composed of basic elements such as a base, a polishing plate, a polishing fabric, a polishing cover and a...
1. As we all know, because the electroplating process of aluminum wheel hub is quite complicated, it uses a variety of brighteners and additives, so its finished product is a sign that shows the level...
Electroplating zinc-nickel alloy refers to the formation of a coating film on the surface of the plated parts at a ratio of zinc to nickel 9:1. This protective coating has developed rapidly in recent ...
What I want to introduce to you today is the electroplating bath charging and density measurement methods. Friends who want to know can learn with this editor. I hope this editor’s explanation will be...
Hot-dip galvanizing (hot-dip galvanizing) refers to the method of immersing the plated fasteners in liquid metal zinc or its alloy for plating. Hot-dip galvanizing is widely used to protect steel and ...
Electroplating zinc on magnesium alloy can greatly improve the corrosion resistance of magnesium alloy surface, and at the same time, it has the advantages of beautiful appearance, high hardness and g...
