- Q: What are the casting parts used to test shrinkage holes?
- 2. x ray. This method can do nondestructive testing, but the cost is higher. Generally, high castings are required.
- Q: How is the silicon sol precision casting part priced? What is the price per ton of casting? Such as 304 material.
- The material is usually steel material price plus the cost (per ton of 2.5-3 million, plus profit).In the Yangtze River Delta region, generally 304 casting price of about 5-5.5 million / ton.The price will be higher if the parts are complex, or a piece weighs less than 100 grams.
- Q: Domestic large steel castings factory which is better, recommend!
- Do the casting manufacturer of large steel castings, Hunan Jinsha heavy industry science and technology limited company, heard that their professional only more than 1 tons of steel castings, anyway, 150T just big, the company won a lot of foundry industry patents should be good.
- Q: the parts of the threaded hole is casting, casting the hole directly, and then tapping or casting, and then punch 10When the casting is ready, punch it again before tapping it Is the hole casting good or is it punched and tapped on the drilling machine after casting?
- There are several casesThe first hole with a diameter of less than 4MM is generally not done, or as a hole location only for a period of less than 10MM.Second for the big hole, some of the reasons for the holding force, we must increase the slope, direct tapping is unlikely, so it still needs post-processingThird for products with high tightness requirements, some cores need to be made even if they are very small, so they can be tapped directlyFourth, some due to technical requirements, regardless of the size of each other's requirements must be made, there is no wayThe above methods are common, and they will encounter many small problems in actual production.
- Q: Casting parts have poor surface finish. What sand is used to make them?
- Manual coal dust, clay sand is a little worse. Mechanical styling is not bad either.
- Q: How to cast iron and wrought iron collocation
- 2, listen: Pig beating sound boring, wrought iron beating sound loud.
- 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
- Q: Which surface is coarser for cast iron or cast steel castings? Why?
- The surface of the steel is more rough, because the coating sand cast steel cast iron particles compared with graphite coating degree, the other one is to get a better air permeability and collapsibility of sand, the compaction degree is smaller than iron.
- Q: In the design of casting steps and precautions, for casting design, we have what experience?.
- A: in the design of metal castings in a complex shape, if the production process is very difficult, should not affect the casting conditions, try to make the casting has simple shape, strong structure change, removed from metallic die for.
- 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,
