The common material of low-pressure casting is A356\ZL101\ZL101A,this kind of material is usually applied to auto part, storage part,transformation part,etc.
The pressure on the surface of the molten metal is 0.06~0.12Mpa.This processing has good shrinkage, casting tissue is dense, easy to produce the large thin-walled complex parts, the casting head is not needed , metal yield can be up to 95%.
Low pressure casting can adopt sand type, metal type, graphite type, etc. The filling process is not only different from gravity casting such as metal casting and sand casting, but also different from high pressure and high speed filling pressure casting, which has the following advantages:
1) Pure metal liquid filling type, which improves the purity of the casting. Because the slag generally floats on the surface of the metal liquid, and the low pressure casting by the metal liquid in the lower part of the crucible realizes the filling through the lifting pipe, which completely avoids the possibility of the slag into the cast cavity.
2) The metal liquid filling type is smooth, reducing or avoiding the turnover, impact and splashing phenomenon of the metal liquid when filling the type, thus reducing the formation of less oxide slag.
3) The casting molding performance is good, the metal liquid filling under the pressure action, can improve the fluidity of the metal liquid, is conducive to the formation of clear outline, smooth surface casting, for the formation of large thin-wall casting is more favorable.
4) The casting crystallizes and solidifies under pressure, which can be fully condensed, and the casting structure is compact.
5) Improve the yield of metal liquid, generally do not need to burst, and the same metal in the lifting tube can be returned to the crucible, reuse, so that the yield of metal liquid greatly increased, the yield can generally reach 90%.
6) Convenient production and operation, good working conditions, high production efficiency, easy to achieve mechanization and automation.
Low pressure casting also has some disadvantages, equipment and mold investment is large; in the production of aluminum alloy casting, crucible and lift pipe long time with metal liquid contact, easy to erosion and scrap, will also make the metal liquid iron and performance deterioration.

Low-pressure casting was the earliest anti-gravity casting technology, which was first used in industrial production in the 1940s. Nowadays, low-pressure casting is mainly used in the production of aluminum alloy and magnesium alloy parts, such as the automotive hub of the automobile industry, the cylinder body, cylinder head, piston, missile shell, impeller, air guide wheel and other castings with complex shapes and high quality requirements.
The name of the medicine to change the name of the drug fraud in Nanjing, a pharmacy to be punished diesel generator | diesel generator price / 2013-02-23
In the past few days, many citizens have responded that when a drugstore in Jiangning, Nanjing, purchases medicines, it often happens that the name of the medicine does not match the name on the settlement slip. Today, the reporter learned from the Health Insurance Center of Jiangning District that the medical insurance center has decided to stop the pharmacy's qualification for medical insurance and pay a certain fine.
Mr. Zhu, a Nanjing citizen, responded that his wife had a cold so he bought several medicines for colds at the Jiangning Minxin pharmacy. While brushing the Medicare card, he discovered that the names of drugs on the consumer list have changed. “The staff in their pharmacy said that you quickly signed the bill. I said that I would look at all the drugs that I bought for me. He said what you see is that these medicines are the same as the price you buy.â€
Although Mr. Zhu repeatedly asked for a change in the name of the drug, the pharmacy sales staff insisted that it was okay and did not change the bill. Mr. Zhu said that once he had taken the drug and wanted to make a complaint, because the list did not show the drugs he had purchased, he had no evidence at all. "I said how these medicines are different from what I have on the list. He said he couldn't fight them. I said that this kind of cold medicine can be used in other pharmacies."
In order to confirm Mr. Zhu’s statement, the reporter came to this pharmacy. When he learned that the reporter had a cold, the sales staff recommended the same drugs that Mr. Zhu bought. In the list of consumption, there was no Chuanbei cough syrup, cold wind tablets, and Zhikebao tablets. Instead, it was a cold masking capsule and intestinal inflammation tablets.
The salesperson explained: “These are all not available, the machine is broken, the price is the same, all are 18 bucks. You do not buy within the scope of the reimbursement. This is the program design, will not deduct more money from the customer's insurance card. If you don't want me, I'll wash you out. It's not that you buy drugs this way. Such a big shop can swipe more than 10,000 yuan a day."
Sales staff said that the reason for changing the name of the drug was mainly due to systemic reasons. These types of drugs cannot be used at any other pharmacy. However, afterwards, the reporter learned from several pharmacies nearby that these kinds of medicines were all brushed out.
After receiving the report, law enforcement officers of the Jiangning District Medical Insurance Center rushed to the scene. The person in charge of the Minxin pharmacy stated that changing the name of the drug is related to the age of the staff: “We are all in their fifties, and we don’t have the pinyin. The young people can transfer the medicine out. We can't tune it out and find the same price. This is how our two old comrades fight."
Law enforcement officials found that some of the drugs prescribed by pharmacies were not in the medical insurance catalog. Among them, Zhikebao tablets belong to self-consumption drugs. In order to attract customers, drugstores replacing non-medicated drugs with Medicare drugs at the same price have clearly violated regulations. Sales staff said that the next step will be strictly in accordance with the requirements of social security.
Ma Ling, director of the Jiangning Medical Insurance Center, said: "The use of medicines for personal medical insurance accounts and co-ordination of funds are all harmful. Medicare card money is actually used to treat people with illnesses, but they are used for other purposes."
At present, the Jiangning District Medical Insurance Center has decided to stop the pharmacy medical insurance qualifications and give a certain fine. At the same time, the pharmacy’s superior department, Minxin Pharmacy Co., Ltd. was investigated.
The person in charge also stated that at present, they have conducted a large-scale investigation of 43 pharmacies that have been designated as medical insurance points in Jiangning District, and have ordered them to sell their non-medicated products for pharmacies and ordered them to unload them.
