Q:How much is the amount of electrophoretic paint per square meter used in the casting?
It was a very simple question, and it was complicated by what you said.
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:We are small castings, the need for surface treatment of shot blasting machine, about how much?
according to the comprehensive consideration of factors such as yield, size of workpiece commonly used on the market the crawler shot blasting machine has Q324, Q326, Q328, Q3210, and each time the amount of their treatment were 125KG, 200KG, 400KG, 600KG, the specific use of what types also need to be determined according to the actual situation
Q:What do you mean by "proofing" in the casting? Do you charge for the proofing?
Proofing? In the casting industry is not called proofing, proofing is generally used in the printing industry, that is, according to the customer's drawings or samples, to do a first piece, to provide customers with the inspection process to meet their requirements;In the foundry industry, providing prototypes is sometimes difficult:1, customers if the provision of mold, it would be best, at this time, sample costs are very low, and almost the same as your regular products;2, the customer does not provide the mold, but in business relationships, your factory and not very sure must take this one, it requires your leadership decision-making, is free or low cost, or by a strict process offer (of course sample);3, not all of the casting process to provide samples are difficult, like lost foam can directly make a white NC prototype, and then assembled pouring, this is her unique advantages, first cost less than the opening process and so on;If you don't understand, you can continue to question me
Q:When the blank is a casting, the margin is evenly distributed, how should rough machining? Twenty
Problem one,1, according to drawings, castings, material requirements and machine power, choose the right diameter of roughing tools, and can process this material blade type.2, according to the actual size of the casting blank, calculate the number and path of the knife, pay attention to small cutting depth, large feed, cutting width, to ensure that the tool diameter 80 - 90%, the amount of not full knife cutting, this tool and machine tool damage.Question two,If they can not change the casting blank allowance under the condition that the quantity large diameter cutter, such as milling cutter main angle 7560 degrees can give reasonable processing parameters, the same cutting depth should not be too large, because in the same machine power, tool diameter increases, cutting depth will need smaller.
Q:What are the effects of stiffeners on castings, or on welded parts (for 2 tons or less), casting or weldments on stiffeners?
3, weight: if reinforcement in products, casting weight is generally greater than the welding parts (the internal organizational structure and mode of production determines the mechanical properties of materials, so it determines the weight of the product), considering the cost of transportation, certain priority structure.
Q:What are the factors affecting the machining process of the casting material and structure?
As for the metallographic structure, usually the finished products after casting are treated by heat treatment. The mechanical properties of the carbon steel after heat treatment (quenching and tempering) are detected. The stainless steels are treated by heat treatment (solid solution, etc.) and the metallographic structure is analyzedThere is a lot of talk and a bit of confusionIf you have a specific brand, you can search for Baidu or buy tools
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:In theory, which is more expensive, forging parts or casting parts?
Compared with the price, the product with the same simple structure eliminates the material factorsThe forgings must be more expensive
Q:Casting parts in rocker arm drilling, reaming, roughness, block.
The finish of reaming depends on the material and the sharpness of the reamer, as well as the speed and speed of the top and bottom. Marine machine tool
