3.Can I have my own Logo on the product?
A: Yes, you can send us your drawing and we can make your logo, but you have to bear their own the cost.
- Q: How to calculate the price of casting parts?
- Cost of raw materials + electricity (fuel) costs + workers' wages + managers' wages + transport costs + raw materials burned + accessories costs + equipment maintenance depreciation costs + management fees + tax. The most convenient, the raw material market price plus 2000 yuan, plus you want profits on the line.
- Q: our factory now produces steel castings in the use of polishing directly after spraying processing, but the powder sprayed 15But the spray powder touched off what is the reason we are not very strict requirements not only need to peel off bubbles can also, because our products are steel castings so we use steam hole sludge put on. Do not know if this spray treatment has no effect to thank friends with us!
- Cast iron has not been done, if it is iron, then in the spray before going through strict pretreatment, the surface can not have a little oil dust
- Q: Explain the heat treatment effect of casting parts, forging parts and welding parts
- The three methods of metal processing have one thing in common. They are hot working, which are different in temperature and range of processing. Ductile cast iron is widely used because of its brittleness and poor impact. Heat treatment of cast iron usually adopts the annealing process, reduce the casting effect: 1 because of the internal stress caused by the thermal expansion and contraction, reduce the deformation after machining, decrease surface hardness, improve machining conditions;
- Q: What are the effects of stiffeners on castings, or on welded parts (for 2 tons or less), casting or weldments on stiffeners?
- 3, weight: if reinforcement in products, casting weight is generally greater than the welding parts (the internal organizational structure and mode of production determines the mechanical properties of materials, so it determines the weight of the product), considering the cost of transportation, certain priority structure.
- Q: What are the casting parts tested?
- The surface brightness, appearance, size, chemical composition, weight, material, surface defects, internal defects, seals need to be checked, leakage, etc.
- Q: What kind of casting process is used for cast iron parts? And what are the cast steel parts adopted?
- The types and uses of foundry sand according to the mineral composition of different silica sand and non siliceous sand is divided into two categories. The main mineral composition of silica SiO2.: natural silica sand used for non-ferrous metal casting, cast iron and steel castings in small sand and core sand. The selection of natural silica sand: used in organic matter as the binder of various sand and core sand. The artificial sand for sand and core sand castings. Non siliceous sand and non siliceous sand have many kinds and different uses. Limestone sand: crushed by limestone, the main mineral composition is CaCO3, used for casting sand and core sand. Zirconium sand: the main mineral composition is ZrO2 SiO2, used for large steel castings and alloy steel pieces of core sand or sand surface sand, or powder used as coating. Magnesia: the main mineral composition is MGO, used for high manganese steel casting surface sand, core sand, and its powder can be used as coating. Chromite ore: the main mineral composition is chromite FeO. Cr2O3, used for large or special casting steel surface sand, core sand, its powder can be used as coating.
- 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 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: Cause of choking of casting parts
- Choke fire is the process of pouring a large number of gases can not be discharged smoothly, boiling in the metal liquid, resulting in a large number of castings in the pores, and even incomplete casting defects
- Q: When there is no flaw detection for large casting parts, is there any crack inside?
- Cracks are considered serious levels of defects and should be repaired
