Q: How to calculate the price of casting parts?
According to the complexity of the workpiece, material and casting requirements and process yield
Q: What are the requirements for casting steel castings?
1, high quality requirements of the surface or the main processing surface should be placed below.
Q: What is the ejection angle of the die casting (Tan Gang)?
Because after the wax, wax parts will have a slight contraction, which is good for demoulding. Many moulds don't do the ejection angle
Q: Is the cast steel a casting part?
Cast steel is one of the casting parts that you call. The material is made of carbon steel or alloy steel, stainless steel, etc. the method is cast
Q: It is generally said that cast iron is re smelted by pig iron. My question is..:1 pig iron for melting iron, is directly cast into products (such as bed cover, etc.); or that is just the first pig iron smelting iron casting, such as to cover, bed and other products, will once again cast iron melt to casting?2, there are many castings to the engine. Are these castings made by the engine manufacturer themselves or bought by others?There is no need to answer all. Thank you!!!
1, qualified enterprises will directly iron ore into molten iron, and then poured into the mold, such a good product performance. I work in the cast iron industry, which I can tell you for sure.2, this, like the Great Wall Motor Company has its own parts production department, as well as the corresponding mold center, so it will be their own casting. If the manufacturer does not have these departments, they can only place orders for others to do.
Q: Casting parts have poor surface finish. What sand is used to make them?
Now resin sand, coated sand and other processes are also very good surface.
Q: What should I pay attention to when designing a casting structure?
The basic structure of unit 3 in the design of metal casting casting and its parameters are selected, usually should also pay attention to: (1) because of the metal type heat quickly, so the metal type casting minimum wall thickness should be bigger than the sand casting casting casting; (2) the inner wall of the internal ribs and the thickness of a should be connected the outer wall thickness of 0.6 to 0.7, or as the inner wall (rib) cold slowly, cracks in the wall at the junction in the casting shrinkage; (3) to prevent generating white grey cast iron, in addition to taking measures in the process, must make the wall thickness is not too thin (some information that cast fillet at the corner of the wall thickness of 15mm or more, with metal casting casting must be in the corner, for Aluminum Alloy, metal casting magnesium alloy castings shall not be less than 3 ~ 4m; (4) because of the metal type and the core that, for To facilitate the extraction of castings and casting out type, slope casting should be suitably large than sand casting metal casting, the general should be 30% ~ 50%, it should be pointed out that in addition to the height of the slope of casting size and alloy type, wall, is also related to the casting surface position, where the cooling and contraction of the metal type the surface of casting surface can be designed from the tendency of small inclination, while casting shrinkage tend to be pressed on the surface of metal casting type should be given greater inclination.
Q: Does anyone know how to make precise casting parts for aerospace or manufacturers of single and small quantities of automotive parts and components, mainly in Beijing, Tianjin and Tangshan?

Q: How to cast iron and wrought iron collocation
So we can only watch and ear distinction: 1, see: Iron fracture is rough, showing a bead (for the sake of coarse grain iron), and wrought iron fracture is generally more smooth; if this is a new fracture, but also to see the dark and shiny born iron wrought iron pig iron is bright; the fracture is generally irregular, because it is very brittle, mostly is interrupted, (which is processed, it is very flat and wrought iron) must not be interrupted, mostly by certain way processed separately, so the fracture is generally neat; if the fracture is that is cutting, wrought iron, iron is not cutting; iron surface will not have pores, familiar iron porosity; if a piece of iron is a significant deformation (bending) that is wrought iron because of poor plasticity It doesn't have to be so deformed, it's really bent, or it's broken, or it's obviously cracked, and it doesn't bend very much. There are some details that can not be made clear. It is necessary to have some experience.
Q: Lathe processing stainless steel casting parts to use what type of tool, the speed into the amount of how much tool angle
There is YW1 best, if not using YG6X, YG8 is ok!The speed should not be high, the greater the diameter, the lower the speed! For example, a diameter of 100 mm, speed is not greater than 80 rpm, each point is good!The main tool is the front angle to be larger, more than 6 degrees, and the groove should be wider and larger to reduce the cutting resistance! When the rear angle is properly reduced and the strength is increased, it is recommended to take 3 degrees.The main components are: spindle box, exchange gear box, feed box, slide box, tool post, tail frame, light bar, lead screw, bed, foot and cooling device.Spindle box: also known as the headstock, it is the main task of the rotary motion of the main motor came through the transmission mechanism of a series of positive and negative spindle to be required two different steering speed, the spindle box gives impetus to the movement of the box. Medium spindle is the key part of lathe. The stability of the spindle on the bearing directly affects the quality of the workpiece. Once the rotation accuracy of the main shaft is reduced, the value of the machine tool will be lowered.
