FAQ
1.Can I get free samples?
A: Yes, we can provide you the free sample, but you need to bear their own delivery costs.
2.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.
3.Can I request to advance the shipment?
A: It should be depends on whether there is sufficient inventory in our warehouse.
- Q: There is a little trace of polishingShock polishing is even worseElectrolysis can not be uneven, there is a slight bump
- Buffing should be better, to see how your embryo, but a bit difficult
- Q: What is the difference between forging parts and casting parts?
- Forging is in hot state through the metal hammer or press equipment produced by forging parts. A casting is a metal that is liquid and is poured into a cavity of a specified shape and cooled and solidified. It is the forging metal soft pinch molding, and casting the metal into thin cooling solidification.Forged parts are costly and have long production cycles.
- Q: It is generally said that cast iron is re smelted by pig iron. My question is..:1 pig iron for melting iron, is directly cast into products (such as bed cover, etc.); or that is just the first pig iron smelting iron casting, such as to cover, bed and other products, will once again cast iron melt to casting?2, there are many castings to the engine. Are these castings made by the engine manufacturer themselves or bought by others?There is no need to answer all. Thank you！！！
- 1, qualified enterprises will directly iron ore into molten iron, and then poured into the mold, such a good product performance. I work in the cast iron industry, which I can tell you for sure.2, this, like the Great Wall Motor Company has its own parts production department, as well as the corresponding mold center, so it will be their own casting. If the manufacturer does not have these departments, they can only place orders for others to do.
- Q: Selection of hydraulic press is the casting parts and steel plate welding, how to choose?
- Casting parts in one shape, the overall processing in this regard than steel plate welding better. The same price is much more expensive than steel. Large hydraulic presses seldom have casting parts.
- Q: Would you please tell me how to use casting parts for a year?The cast of an aircraft wing needs to be put aside for a year before it breaks;Does anyone know why?
- There are various casting stresses after casting, which can be divided into two kinds: thermal stress and shrinkage stress. In a long time placed in the atmosphere, called aging treatment.Aging treatment is an effective measure to eliminate casting stress. Aging is divided into natural aging, thermal aging and resonance aging.1, the so-called natural aging, the casting is placed in the open field for more than half a year, so that the internal stress relief.
- Q: Why do casting parts have air holes?
- First, from the source, tools, raw material drying, in the process of melting into the reaction gas, another influence is pouring process, such as high temperature solidification gas dissolved too much after not excluded. The method can adjust the pouring temperature properly, control the source of gas (drying and controlling the inoculant, especially the content of magnesium), and add cooling iron to change the solidification mode. It depends on what kind of casting you are. You can't make it clear at once. And molding sand relationship is mainly water content and permeability, brush coating resin content.
- 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: Which surface is coarser for cast iron or cast steel castings? Why?
- The surface of the steel is more rough, because the coating sand cast steel cast iron particles compared with graphite coating degree, the other one is to get a better air permeability and collapsibility of sand, the compaction degree is smaller than iron.
- Q: What do you mean by "proofing" in the casting? Do you charge for the proofing?
- Proofing refers to making the first sample to confirm to the customer
- Q: What's the cause of the choking of the casting?,
- Causes of choking fire:1., casting material in the pouring of gas;
