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:Heat treatment process and purpose of casting parts: Objective: to stabilize tissues, eliminate or substantially reduce internal stress.

Q:What foundry factories are used in the casting parts of China's major automobile manufacturers?: This is too muchYou do not have a specific list of statistics, but there are many foundries in china!Moreover, car prices are unlikely to be ordered in the local factories!

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 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:Where is the precision casting factory?: Shandong, DongyingThe birthplace of precision casting

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: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:The casting defects of pores, trachoma how to repair?: Airhole above 2mm recommended LT101 casting defect repair agent. If repair quality requirements, high availability LT111 iron repair agent, LT112 steel repair agent, LT113 aluminum repair agent, LT114 copper repair agent.

Q:Which surface is coarser for cast iron or cast steel castings? Why?: Roughness mainly depends on the surface roughness on the surface of the sand.
