Q:What's the density of casting?
Uneven casting density is caused by uneven shrinkage of the casting during solidification.
Q:What is the difference between forging parts and casting parts?
The forging can guarantee the continuity of the metal fiber tissue, make the fiber structure of the forging keep the same shape as the forging, the metal streamline is complete, the tissue is compact, and the mechanical property is good. To ensure that the object has good mechanical properties and long service life, the processing of objects sharp, durable, high strength, first-class quality.
Q:Cause of choking of casting parts
Is it boiling from the picture? Does it sound like a fire? If not, it's not choking. I feel like choking. The gas doesn't drain out
Q:What's the cause of the choking of the casting?,
3. when casting the environment is humid, sand mold has not removed the moisture, when the casting, the moisture instantaneous transforms into the steam, causes the blowhole
Q:How can the casting be quenched and tempered?
Another is the result of pre heat treatment (quenching or annealing) after quenching and tempering treatment, suitable for ZG35SiMNMo, ZG35CrMo and so on. Please tell the casting process is your product and material and then set tempered.: shutup:
Q:Shandong foundry, casting small pieces of precision casting
Small foundry in Shandong too much, like many of us in Qingdao, then Dongying Changshun investment casting is a home, they are also casting precision casting equipment, specifically what I recommend that local enterprises, far is not convenient,
Q:Why should pig iron be used in casting?
Cast iron is generally called pig iron, but casting is not merely iron casting.For example, injection molding, die casting, and so on, in fact, cast iron, cast steel, cast aluminum, plastic and so on, can be used in the form of casting processing molding
Q:What are the effects of stiffeners on castings, or on welded parts (for 2 tons or less), casting or weldments on stiffeners?
Please consider the following points:1, batch: if the product batch is very large, casting will certainly have advantages, cost sharing will be very low. If less, it is recommended to use weldments.2. Reinforcement structure: if the structure is relatively simple, it is recommended to use welded parts, complex, preferably casting.
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 angleEspecially deep hole, and customers to discuss, generally take 0.3-1 degrees is enough
Q:Casting parts in rocker arm drilling, reaming, roughness, block.
The finish of reaming depends on the material and the sharpness of the reamer, as well as the speed and speed of the top and bottom. Marine machine tool
