Q:Domestic large steel castings factory which is better, recommend!
Do the casting manufacturer of large steel castings, Hunan Jinsha heavy industry science and technology limited company, heard that their professional only more than 1 tons of steel castings, anyway, 150T just big, the company won a lot of foundry industry patents should be good.
Q:Why do cheap cars like stamping parts instead of casting parts?
The difference between automobile stamping parts and castingsAs the saying goes, there will be progress in comparison. In fact, through comparison, we can find the advantages and disadvantages of both. Next, we will talk about the difference between car stamping parts and castings.Looking for national casting orders, ductile iron castings, purchasing castings, foundry orders, and consulting foundry technology issuesCasting order networkAutomotive stamping parts are widely used in every field of our life, including some electronic components, auto parts, decorative materials and so on.
Q:Why do casting parts have air holes?
First, from the source, tools, raw material drying, in the process of melting into the reaction gas, another influence is pouring process, such as high temperature solidification gas dissolved too much after not excluded. The method can adjust the pouring temperature properly, control the source of gas (drying and controlling the inoculant, especially the content of magnesium), and add cooling iron to change the solidification mode. It depends on what kind of casting you are. You can't make it clear at once. And molding sand relationship is mainly water content and permeability, brush coating resin content.
Q:How can the casting be quenched and tempered?
Return, general castings (especially steel castings) commonly used heat treatment process is normalized and tempered. Of course there are completely by annealing or remove stress annealing...
Q:Can the casting part be phosphating with the phosphating solution of the pickling board?
Like stainless steel casting, duplex stainless steel casting is phosphating, ductile iron gray iron is not required
Q:What is the difference between the casting drawing and the car work drawing?
What you say is the difference between rough drawing and processing drawingThere must be a difference between the rough drawings and the rough ones
Q:The casting defects of pores, trachoma how to repair?
If the repair after the high temperature resistance, choose LT737 high temperature repair agent.
Q:What is the casting material?
Kdl1588n said in detail, casting a lot of material, steel, iron, aluminum, copper, zinc, etc. can be, valuable, as well as gold and silver, the most common on cast steel and cast iron, cast aluminum and so on.
Q:Heat treatment process and purpose of casting parts
Methods: artificial aging or natural aging (also called normalization) treatment.Artificial aging: heating to 2-3 Baidu, it is best to apply mechanical vibration, and maintain a period of time.
Q:How to improve the surface roughness of casting parts?
One is to improve the accuracy of the model; the two is to improve the molding sand mesh. How much is the other relationship?.
