The urea master unit of Huahe Coal Chemical Co., Ltd., which was constructed by China Chemical Engineering Fourth Construction Co., Ltd., has an annual output of 300,000 tons of synthetic ammonia and 520,000 tons of large-grain urea project (referred to as the 3052 project). The project is located in Dongshan District, Hegang City, Heilongjiang Province and is a key construction project in Heilongjiang Province. The total investment of the project is 3.45 billion yuan. Major equipment and technology are imported from abroad. It is one of the seven major production bases planned by China National Chemical Industry Co., Ltd., which is listed as the revitalization of the northeast old industrial base in Heilongjiang Province and the development of coal power in eastern Heilongjiang Province. Base major projects. Sihuajian Construction Co., Ltd. undertook the construction of the urea main unit and public works of the third section of the project. The amount of the contract is tentatively scheduled to be 98.80 million yuan. It is scheduled to be completed on December 30, 2013. In order to build this project safely, high-qualityly, and efficiently, the company's service philosophy is to “build a project, build a fame, and make friends from one sideâ€, organize construction teams that can compete for excellence and put it into construction, and strive to turn the project into a quality demonstration. engineering.
The domestic current
situation of the die-casting mould
Die Casting Mould industry
has developed rapidly in our country, the total output growth significantly,
domestic die casting mold production after the United States, has become the
second in the world, become the veritable die-casting superpower. It can have
such achievement because of our country with unique broad market advantages and
relatively cheap labor force. Depend on very obvious price in the international
trade market, we produced the die casting mould which occupies a bigger
superiority, according to the situation, in the future Chinese die casting
industry development prospects are very broad.

What is the Moldflow analysis, this conception
derived fromtaiwan.
it's a precess through the computer for injection molding simulation by data
simulate software, and get data result. Then assess the feasibilty of the mold
program through these results to perfect mold and production designation.The
common software for plastic mold such as moldflow, moldex 3D and so on. And the
common software for Aluminum Die Casting Parts such as PROCAST, FLOW 3D and so
on.

1, According to the materials, shape and precision product, analyze technology,
decide of the process.
2, Confirm the location of product in the mold cavity. Analyze parting surface,
overflow system and the gating system.
3, Design the various activities of the core are assembled and fixed method.
4, Design the core-pulling distance and force.
5, Design the ejection device.
6, Confirm the die casting machine, design the mould base and the cooling
system.
7, Checking the mould size and die casting machine, drawing the process
flowchart and component of die casting mold.
8, Design is complete.
