Q:Casting parts by shot blasting, spray painting, baking after the formation of very small rust spots, how to solve ah?: The first process is very important. Shot blasting must be thorough. The solution is to wipe the surface of the paint with a release. Re shot

Q:For example, casting parts contain many holes, inclusions and other defects, the size and the number of holes exceed which limit is not qualified: According to different casting process and parts materials, each has relevant standards, can be found online;

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:I often see Waixiejiagong drawings, casting, how to distinguish the latheman.: The technical condition or the material column in the title column will tell whether it is a casting drawing or not. However, the need for casting drawings, and some also through machining (car, milling, etc.), this should be part of the process drawings, process drawings are described

Q:What is the difference between forging parts and casting parts?: No, it's called die castingDifference: the die casting parts are simple in structure and large in batch sizeCasting: the use of a wide range of structures without restrictions

Q:What's the cause of the choking of the casting?,: Causes of choking fire:1., casting material in the pouring of gas;

Q:What is the ejection angle of the die casting (Tan Gang)?: Especially deep hole, and customers to discuss, generally take 0.3-1 degrees is enough

Q:What is the difference between casting and stamping parts?: The purpose of forming processes is to allow the sheet to undergo plastic deformation without breaking the billet and to make the desired shape and size. In actual production, a variety of processes are often applied to a workpiece. Blanking, bending, shearing, drawing, bulging, spinning and rectification are several main stamping processes. The difference between stamping parts and castings: with thin, uniform, light, strong features, stamping can be produced by other methods difficult to make, with stiffeners, ribs, UPS or flanging of the workpiece, to improve its rigidity. Due to the use of precision molds, the workpiece accuracy up to microns, and repeated high precision, specifications consistent, you can punch out of the hole, lug and so on.

Q:Explain the heat treatment effect of casting parts, forging parts and welding parts: 2 improve the crystal structure, enhance the formation and stability of spherical carbon crystal;Forgings are generally stress bearing members, and most of them are made of high strength medium carbon steel (alloy), which is formed by forging and fine crystalline. After the shell is annealed or quenched and tempered, the mechanical properties of the shell are more superior, and it has better strength and better elasticity;Welding materials.

Q:What do you mean by "proofing" in the casting? Do you charge for the proofing?: Proofing? In the casting industry is not called proofing, proofing is generally used in the printing industry, that is, according to the customer's drawings or samples, to do a first piece, to provide customers with the inspection process to meet their requirements;In the foundry industry, providing prototypes is sometimes difficult:1, customers if the provision of mold, it would be best, at this time, sample costs are very low, and almost the same as your regular products;2, the customer does not provide the mold, but in business relationships, your factory and not very sure must take this one, it requires your leadership decision-making, is free or low cost, or by a strict process offer (of course sample);3, not all of the casting process to provide samples are difficult, like lost foam can directly make a white NC prototype, and then assembled pouring, this is her unique advantages, first cost less than the opening process and so on;If you don't understand, you can continue to question me
