A: Yes, you can send your logo design to us and send us the authority letter. Then we can cast the logo on body.

Q:What are the general technical requirements for casting parts?
According to the national standard GB/T 9438, there are 8 aspects: 1. chemical composition; 2. delivery status; 3. mechanical properties; 4. dimensional tolerances; 5. weight tolerances; 6. appearance quality; 7. internal quality; 8. casting salvage.
Q:It is generally said that cast iron is re smelted by pig iron. My question is..:1 pig iron for melting iron, is directly cast into products (such as bed cover, etc.); or that is just the first pig iron smelting iron casting, such as to cover, bed and other products, will once again cast iron melt to casting?2, there are many castings to the engine. Are these castings made by the engine manufacturer themselves or bought by others?There is no need to answer all. Thank you!!!
1, qualified enterprises will directly iron ore into molten iron, and then poured into the mold, such a good product performance. I work in the cast iron industry, which I can tell you for sure.2, this, like the Great Wall Motor Company has its own parts production department, as well as the corresponding mold center, so it will be their own casting. If the manufacturer does not have these departments, they can only place orders for others to do.
Q:How to distinguish the forging parts and casting parts accurately
To distinguish from the use of materialsForging materials are mainly made of carbon steel and alloy steel of various components, followed by aluminum, magnesium, titanium, copper and their alloys. The original state of the material is rod, ingot, metal powder and liquid metal. The materials needed for casting are mostly metal, wood, fuel, molding materials and so on. In contrast, the forging parts rarely produce dust, harmful gas and noise, etc., and play a more obvious role in environmental protection. Of course, because of this, the price of forged parts on the market is higher than that of castings.
Q:What kind of flaw detector is better for casting parts?
If you want to detect internal defects, you can use ultrasonic flaw detector, ray flaw detector can also, but the ray of the safety protection level is too high, not recommended priorityMacro Xu flaw detector answered, such as the magnetic particle inspection machine has the demand can contact us, Baidu "macro Xu flaw detection""
Q:How is the silicon sol precision casting part priced? What is the price per ton of casting? Such as 304 material.
I am doing this for sale, if the price is mainly based on the product structure, the difficulty of pricing. At present, if it is more formal and material guarantee manufacturers generally in 48-53 yuan /Kg (of course, products have a certain weight, such as greater than 100g), our company's current price of about 53 yuan /Kg or so. .
Q:our factory now produces steel castings in the use of polishing directly after spraying processing, but the powder sprayed 15But the spray powder touched off what is the reason we are not very strict requirements not only need to peel off bubbles can also, because our products are steel castings so we use steam hole sludge put on. Do not know if this spray treatment has no effect to thank friends with us!
You oily sludge!Is not the general market on the soil?If it isPlease use two groups of chemicals to reinforce the soilOr suggest your company?Do the putty or paint film after doingThat's better
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?

Q:What's the effect of casting copper?
Copper is one of the main corrosion resistant alloys. When the mass fraction of copper in cast iron is from 0.25% to 1%, the corrosion resistance of copper in the industrial atmosphere can be obviously increased. But copper has very little corrosion resistance in lye or salt solution.Copper can increase the flowability of molten iron and improve its casting ability remarkably.Copper can increase the coercive force and residual magnetic force, but the permeability is not affected.Combined use of copper with other alloy elements, such as copper chromium, copper chromium molybdenum, copper molybdenum, copper manganese, copper vanadium, can achieve greater results.
Q:What should I pay attention to when designing a casting structure?
1 of the casting in metal mold cooling was faster than sand, metal type and let, thus casting in metal mold casting, casting stress generated in the ratio of sand casting to crack tendency is also large, but also prone to misrun and cold lap, white (for casting casting). Defect. Usually: (1) in the prevention of metal casting casting crack aspect should pay attention to the following problems: the structure of A in wall thickness, wall transition and connection to the ease, corner fillet appropriate requirements such as should be more strict than sand casting; B should be connected vertically connected with the wall to tilt C; for the weak parts of the structure should be set to strengthen ribs, bosses, to prevent casting; D should minimize the obstacle free shrinkage of the boss, casting rib, flange and other prominent part; E in the casting arrangement of ribs, but also should consider its influence on the casting shrinkage.
Q:As shown, how do I achieve the tightness test of this product, and achieve industrial production? Seek expert advice.
Precise and tight sealing of the surface to which the test piece is to be tested, equipped with an airtight test instrument, and an electrical control system. You can complete automated testing equipment
