Q:Cast iron, casting parts 5
The first to ask, such as casting end cover, bed and other products, is to put the iron melting and casting againThe two question, their casting castings manufacturers than to buy professional casting factory production, production quality more security professional.
Q:ZGMn13 casting parts processing, with what knife head good?
The ZGMn13 itself is not have processing, if only the processing point, sharpening, ordinary can, if the processing area is relatively large, ZGMn13 external impact load is bigger, its surface wear resistance is high; the two is with the gradual wear of surface hardening, the hardening layer is continuously formed new if you have suggestions, processing, plasma cutting or flame cutting try
Q:Does anyone know how to make precise casting parts for aerospace or manufacturers of single and small quantities of automotive parts and components, mainly in Beijing, Tianjin and Tangshan?
List of China's military enterprises list of ten major military groupsChina Nuclear Industry Construction Group CorporationChina Aerospace Science and Technology CorporationChina Aerospace Science and Engineering CorporationChina Aviation Industry CorporationChina Aviation Industry Corporation IiChina State Shipbuilding CorporationcsicChina North Industries Group CorporationChina South Industries Group CorporationChina National Nuclear CorporationKey military enterprisesShipbuilding industry:China State Shipbuilding Corporation (South ship group), (China Shipping Group)China Shipbuilding Industry Corp (North Ship group), (China Shipbuilding Industry)Guangzhou Shipyard International Limited by Share Ltd (GSI)Jiangnan Heavy Industry Limited by Share Ltd (Jiangnan Heavy Industry)Nuclear industry:China National Nuclear Corporation (CNNC)China Nuclear Industry Construction Group Corporation
Q:How can the casting be quenched and tempered?
Cast steel annealing or normalizing parts in strength and toughness is insufficient, can be used in quenching and tempering treatment. It is mainly used for gear, gear and other parts of the cast steel. The conditioning has two kinds: one kind is cast directly after quenching and tempering, with warm water (40---50 degrees) intermittent cooling, suitable for ZG270---500, ZG310----570 and other castings.
Q:What are the casting parts used to test shrinkage holes?
2. x ray. This method can do nondestructive testing, but the cost is higher. Generally, high castings are required.
Q:What are the causes of pitting on the surface of a precision casting?
There is a bump on the mold. Or casting cooling fast.
Q:What is the ejection angle of the die casting (Tan Gang)?
Because after the wax, wax parts will have a slight contraction, which is good for demoulding. Many moulds don't do the ejection angleEspecially deep hole, and customers to discuss, generally take 0.3-1 degrees is enough
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:How can the casting be free of trachoma?
Measures for the prevention of trachoma in castings:1, sand compaction to high, paint two times;
Q:How to cast iron and wrought iron collocation
So we can only watch and ear distinction: 1, see: Iron fracture is rough, showing a bead (for the sake of coarse grain iron), and wrought iron fracture is generally more smooth; if this is a new fracture, but also to see the dark and shiny born iron wrought iron pig iron is bright; the fracture is generally irregular, because it is very brittle, mostly is interrupted, (which is processed, it is very flat and wrought iron) must not be interrupted, mostly by certain way processed separately, so the fracture is generally neat; if the fracture is that is cutting, wrought iron, iron is not cutting; iron surface will not have pores, familiar iron porosity; if a piece of iron is a significant deformation (bending) that is wrought iron because of poor plasticity It doesn't have to be so deformed, it's really bent, or it's broken, or it's obviously cracked, and it doesn't bend very much. There are some details that can not be made clear. It is necessary to have some experience.
