FAQ
1.Can I request to change the form of packaging and transportation?
A:Yes,We can change the form of the packaging and transportation according to your request, but you have to bear their own costs incurred during this period and the spreads.
2.Can I request to advance the shipment?
A: It should be depends on whether there is sufficient inventory in our warehouse.
- Q: What are the factors affecting the machining process of the casting material and structure?
- The impact on the machining is obvious, it should be the material and heat treatment of the castingCarbon steel parts should be treated by heat treatment (annealing) without special conditions. It can effectively prevent the uneven hardness and hard points. It is easy to turn.
- Q: How to improve the surface roughness of casting parts?
- One is to improve the accuracy of the model; the two is to improve the molding sand mesh. How much is the other relationship?.
- Q: Casting parts need to be subjected to the kind of heat treatment after the weldment is finished
- This is difficult to say, the key is to see the specific parts and components, the final mechanical performance requirements.For example, gray cast iron, usually graphite annealing, to heat treatment annealing, surface quenching and so on, ductile iron can be a variety of annealing, normalizing, quenching and isothermal quenching, surface treatment, chemical treatment and so on, in a word, heat treatment of steel can usually, nodular cast iron can do. Malleable cast iron and vermicular cast iron are often subjected to graphitization annealing and stress relieving annealing, while wear-resistant cast irons often undergo quenching + low temperature tempering, and so on.Welding is the case, such as bearing steel welding must be quenched + low temperature tempering, machine spindle welding (repair welding) must be quenched and tempered treatment, and so on. Of course, if it is a general weld, there is no need for heat treatment or, at most, stress relieving annealing.
- Q: How do casting parts remove stress?
- Annealing treatment, according to different casting annealing treatment, eliminate thermal stress, if need to restore hardness or increase hardness, and then quenching treatment
- 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: I often see Waixiejiagong drawings, casting, how to distinguish the latheman.
- What you say is the difference between rough drawing and processing drawingThere must be a difference between the rough drawings and the rough ones
- Q: What are the causes of pitting on the surface of a precision casting?
- The quality of the shell surface is out of order. Or shot blasting out of question.
- Q: How can the casting be plated with ordinary zinc plating? The coating is too thin and requires 0.08 thickness
- Hot galvanizing doesn't seem to workThe zinc layer is 275g/ square meters of material coating is 0.019mm (mm), up to 0.08 thick.
- Q: Why should pig iron be used in casting?
- 1, in the absence of special requirements, the most important thing is that the price is cheap.2, pig iron castings quenching process requirements are not high. You can do it by hand.3, pig iron casting hardness is very large, can meet many requirements.4, pig iron castings, high temperature resistance is relatively strong. Like stoves are pig iron castings.5, pig iron casting plasticity is very bad, but in some experiments, but use this weakness to improve the sensitivity of the experiment.Wait
- Q: Which master knows how the casting tolerances for malleable iron, gray iron and ductile iron should be chosen? Hurry up, thank youCan you provide a tolerance scale for castings, please?
- Usually manual molding optional CT11 class, ordinary machine modeling optional CT10 class, high pressure molding should reach CT9 level. The tolerances on the wall thickness of the casting are comparable to those of other dimensions of the same casting.
