Q:Casting parts have poor surface finish. What sand is used to make them?: Manual coal dust, clay sand is a little worse. Mechanical styling is not bad either.

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:How can the casting be free of trachoma?: 2, pouring temperature should be enough, otherwise the sand can not float up;

Q:Shandong foundry, casting small pieces of precision casting: Dongying Huayang precision casting factory, the smallest to do 2G pieces.

Q:What method of casting does not rust? I think the sample is like oil: The surface of a general casting is easy to rust. In order to prolong the rusting period, antirust paint or antirust oil is usually sprayed. What you said should be anti rust oil.

Q:What is the casting material?: The casting material is usually made of gray cast iron, nodular cast iron and vermicular graphite cast iron

Q:What is the difference between casting and stamping parts?: Cold stamping is generally no longer done by cutting, or only a small amount of cutting is required. The precision and surface state of hot stamping parts are lower than those of cold stamping parts, but they are better than those of castings and forgings, and the amount of cutting is less.Stamping is mainly based on process classification, can be divided into separation process and forming process two major categories.

Q:How to calculate the price of casting parts?: According to the complexity of the workpiece, material and casting requirements and process yield

Q:How to solve casting defect casting?: Different defects, different solutions, some shortcomings, the current domestic level can not be resolved

Q:Which surface is coarser for cast iron or cast steel castings? Why?: Roughness mainly depends on the surface roughness on the surface of the sand.
