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.

Jin Baoxun (Reporter Hu Zhiyuan Yue Deliang) Chen Jinyi, who has been "closed and practiced" for nearly 4 months, released the latest news to the newspaper yesterday. It was commissioned by the Zhejiang Economic and Trade Commission. The Hangzhou Economic Commission was just hosted in Hangzhou by Zhejiang Jinlunxiao. The provincial-level new product appraisal meeting undertaken by Lin Energy Development Co., Ltd., the controversial “Jinyi HS-W Micro-Emulsified Biodiesel†passed the appraisal.
It has been rumored that the constant "water to oil" has finally settled.
"On September 1 this year, the Zhejiang Provincial Safety Production Supervision Administration issued a certificate of approval for the production of hazardous chemicals, which is a 'birth certificate', and this time I got the 'ID card'!" Chen Jinyi has a firm face and has accumulated in his heart for many years. "疙瘩" suddenly untied.
Identification of "Golden Oil" can replace No. 0 diesel
The appraisal committee unanimously approved the identification of new products for emulsified oil, and hopes to officially put into production and promote the application. It is understood that the nine professors (senior workers, researchers) from the Tsinghua University, Zhejiang University, Sinopec Hangzhou Refinery Research Institute and other seven units, Zhejiang University Chemistry Department of the Institute of Catalysis, doctoral tutor Zheng Xiaoming Chairman.
In the appraisal opinion confirmed by Zheng Xiaoming and other signatures, the reporter found that the appraisal committee gave three opinions: the technical data of Jinyi HS-W micro-emulsified biodiesel is basically complete, which can guide the production; the vegetable oil is processed and converted into high efficiency. Micro-emulsifier, used to formulate diesel and water into micro-emulsified biodiesel, is an innovation in technology, reaching advanced level; replacing some diesel oil with diesel oil, with remarkable environmental protection effect and obvious economic benefits, and has certain energy-saving effect. After trial use by users, Jinyi HS-W micro-emulsified biodiesel can replace the commercially available No. 0 diesel.
The journey of billionaires into a "negative Weng"
In the face of this late "encourage", Chen Jinyi is still excited. Because he courageously launched the project in the world, he made all the family members, and the inexhaustible investment made the former billionaire actually fell into the "Lao Lai" incident.
After the incident, Chen Jinyi went to the court in time to explain the reasons for the temporary inability to pay the debts, and praised the court's initiative, saying that because the company is currently conducting research on major scientific research projects, it needs financial support.
Jinyi Bio-Emulsifying Oil, a typical independent innovation project, has encountered such a dilemma and cannot be thought-provoked. Professor Yao Xianguo, member of the Zhejiang Provincial Government Economic Construction Advisory Committee and dean of the School of Public Administration of Zhejiang University, said: "It is not controversial. The truth is more and more clarified, and the development of science has never been smooth. The problem is to resolve disputes and make scientific decisions. Mechanism.†Yao Xianguo urged that the society must have an institutional environment and support system to promote innovation. It must work hard in the system norms and social environment, and solve key links such as integrity construction, market order, intellectual property protection, and innovation benefit distribution.
The prospect of "Jinyi Oil" has become "Xiangxiang"
The Zhejiang Provincial Federation of Industrial Economics, the Provincial Enterprise Confederation, and the Provincial Entrepreneur Association, which were insulted by Chen Jinyi’s spirit, recently filed a report with the provincial government on the relevant situation of Zhejiang Jinyi Group, and immediately received the deputy governor of Zhejiang Province, Jin Deshui. Instructed to ask the relevant departments to demonstrate the Jinyi “Emulsified Oil†project.
Zheng Yumin, director of the Zhejiang Provincial Administration of Industry and Commerce, also said at the 4th China Private Enterprise Summit held in early November that in the Chen Jinyi incident, private entrepreneurs in Zhejiang showed unity and balance. Entrepreneurs must fulfill their social responsibilities and carry out social innovation. The public must have a little more social understanding and be tolerant of the setbacks of innovation.
With the development of the project argument, Chen Jinyi's “Jinyi HS-W Micro-Emulsified Biodiesel†project has become a “Cinnamon†in the corporate world. The prospect of emulsified oil is being recognized by more and more domestic and foreign companies. Some of them show a strong investment interest. Chen Jinyi revealed to reporters that they are currently implementing plant oil planting bases in several western provinces and agreeing with the relevant consortiums to pave the way for the large-scale industrialization of the project.
Chen Jinyi also revealed to the newspaper that nearly 20 domestic and foreign consortia are extending the olive branch to Jinyi Group; British Fox International Consulting Group officially settled in Jinyi Group. The original production and marketing system of the highly controversial Jinyi Group in the public will be fully activated.
Chen Jinyi said: "The future that everyone expects is becoming a reality." He specially entrusted this newspaper to all friends and relatives.
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.
Zhejiang Water-to-Oil Project won the government's approval for No. 0 diesel
Chen Jinyi, who has been in China for nearly four months, said yesterday that the controversial “Jinyi HS-W Micro-Emulsified Biodiesel†passed the test after being appraised by experts including Tsinghua University. At this point, the constant "water to oil" has been rumored to have finally settled.
