Q:How to judge whether the casting is qualified?
According to different casting process and parts materials, each has relevant standards, can be found online;
Q:Stainless steel mirror polishing precision casting parts is very difficult, 20
German winter three step mirror polishing 2013 new processYou can free proofing!
Q:Shandong foundry, casting small pieces of precision casting
Small foundry in Shandong too much, like many of us in Qingdao, then Dongying Changshun investment casting is a home, they are also casting precision casting equipment, specifically what I recommend that local enterprises, far is not convenient,
Q:Casting pieces of plastic processing requirements can not fall off the skin,
Usually after rusting,Did you peel it?If it isNeed to do film processingIf notPlease look for the coating factoryBetter paint (such as epoxy ester, etc.)
Q:Cause of choking of casting parts
The reason is not in the coated sand, see coating gas evolution, the best use of zircon powder coating (low gas evolution), there is a mold according to a vent needle, this depends on your way is flat or vertical pouring pouring pouring, if vertical pouring, venting pin on the die, and the big piece how could the plane, pouring water flat, a breath, a taboo ah!
Q:The difference between cement sand castings, resin sand castings and vacuum casting parts
Our country or international, in all casting production in 60 ~ 70% by sand casting is produced, of which about 70% is used in the production of clay sand. The main reason is that the cost of sand casting is low compared with other casting method, simple production process and short production cycle. So as the car engine cylinder body the cylinder head, crankshaft castings are produced using clay wet sand molding process. When the wet type can not meet the requirement to consider the use of clay sand table dry sand, dry sand mold or other sand.
Q:When the blank is a casting, the margin is evenly distributed, how should rough machining? Twenty
Personal advice:Because of the large margin, your outline is easy to guarantee;So the key is to consider the assembly and aesthetics of the casting. You have to find the machining criteria;Rough the datum so that it can be machined;After the outline, turn back to the finishing line.If the casting requirement is not high, the benchmark can be directly processed; (not recommended)Over
Q:How to collect exothermic process of casting blank?
Casting, do not need to provide a rough casting foundry drawings, according to your chart will put foot margin in the processing needs of the surface, the rest of the size can be found according to the mechanical design manual and manual casting.
Q:What do you mean by "proofing" in the casting? Do you charge for the proofing?
Die die must charge, wood cheap, expensive aluminum mold
Q:What are the design considerations for casting parts?
(3) to prevent generating white grey cast iron, in addition to taking measures from the process, must make the wall thickness is not too thin (some sources indicate that the corner wall thickness above 15mm, metal type casting must be in the corner, for Aluminum Alloy, magnesium alloy casting casting casting Create fillet should not be less than 3-4m, for casting round cast iron, copper alloy mould casting can see table 1.1-32 selection; (5) because of the metal and the core without let, for the convenience of the casting is taken out and the draw out type, slope casting casting should be suitably large than sand casting metal casting. General 30%-50%, it should be pointed out that in addition to the height of the slope of casting size and alloy type, wall, is also related to the casting surface position, where the cooling and contraction and metal surface of casting surface can be designed from the tendency of small inclination, while casting shrinkage tend to be pressed on the surface of metal castings the type should be given greater inclination, all kinds of metal type alloy casting casting casting.
