2. What is your minimum order requirement?
We will indicate the MOQ for each item in the quotation sheet. we accept the sample and trial order. If the quantity of single item can't reach the MOQ, the price should be sample price.

Q: What are the casting parts used to test shrinkage holes?: 1. anatomy. It is easy to slack off by sawing and machining.

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: What are the requirements for casting steel castings?: 4 thickness, most should be placed above the.5 and try to reduce the number of.6, the sand core should be used in classification of flat surface

Q: How to get rid of casting sand inside casting parts?: Are you saying that in the sand casting cavity? We use the manual blast, he is like a pipe will be automatic shot out of the grit, into the casting cavity, to remove the internal cavity in the purpose of casting sand!

Q: The casting sand is going on: 3, prevention measures(1) to improve the strength of sand mold (core), especially surface strength, high temperature strength, refractoriness, compact, better coating, good core coating and parting surface coating.(2) mould and box can prevent damage;(3) the core should have clearance.

Q: After reaming, the roughness can reach several levels, that is to say, the sample.Casting parts in rocker arm drilling, reaming, roughness, block.

Q: The cause of fracture and why there is no toughness: This question is too broad, see what the casting casting Oh in order to reduce the wayward cast steel, ductile iron, gray iron and white iron, you can choose the material according to their own requirements.

Q: How to distinguish the forging parts and casting parts accurately: Distinguish from scopeShanghai Zhejiang forest auto parts experts pointed out that the forging process can eliminate cast loose, metal welding holes, so an important part of high load working conditions, severe machinery, in addition to relatively simple shapes can be rolled plates, profiles or welded parts, the forging process. Because of its low cost and good economy, casting parts processing is widely applied and belongs to the basic process of modern machine building industry.

Q: What's the cause of the choking of the casting?,: 2. when casting mold exhaust condition is not good, in the casting material use consider whether and hinder its gas permeability; in the process to consider to release more pores, multi venting; core exhaust is particularly important.
