Because the application of aluminum die-casting processing parts will greatly reduce the quality of the entire vehicle, and while improving the vehicle's power performance, it will reduce the emission of pollutants.
There is a big gap in the bearing capacity of aluminum compared with steel, and due to the limitations of current production technology, the cost remains high, which limits its application in automobiles. It is a kind of application with high elongation in the as-cast state. In addition to aluminum and unavoidable impurities, the aluminum alloy used in die-cast components is composed of 8.0-11.5 wt% silicon, 0.3-0.8 wt% manganese, 0.08-0.4 wt% magnesium, up to 0.4 wt% iron, and up to 0.1 wt% It consists of copper, up to 0.1% by weight zinc, up to 0.15% by weight titanium and 0.05-0.5% by weight molybdenum. The alloy preferably also contains 0.05-0.3% by weight of zirconium, 30-300ppm of strontium or 5-30ppm of sodium... less

Molecular formula: (R2SiO)x
Properties: A polymer with Si—O—Si bond to form the main chain structure. It is customarily called silicone or polysiloxane, which can be linear, cyclic or cross-linked polymers.
According to product application, it is classified into three categories: silicone oil, silicone rubber and silicone resin.
The raw material for the synthesis of siloxane is the derivative of silane SinH2n+2. Linear siloxane and cyclic siloxane can be obtained by hydrolysis of R2SiCl2 type organochlorosilane. Use R2SiCl2 and RSiCl3 type organochlorosilane to hydrolyze and polycondensate to obtain crosslinked siloxane.
Siloxane is stable to heat and chemical agents, is not wetted by water, has outstanding aging resistance, excellent hydrophobicity and electrical... less

They are not suitable for materials that contain solids because they can cause premature wear. Internal gear pumps are self-priming and can be used for low NPSH applications. They usually provide a smooth, continuous flow. In theory, at least they are two-way. They can be designed in series to provide separate or combined fluid power systems.
Internal gear pumps have a wide range of applications in many industries: food manufacturers use them to deliver thick pastes and seasonings; the petrochemical industry deploys them in high-pressure metering applications, and engine manufacturers use them for oil delivery. They are used as transfer pumps. Special design can be used for aerospace applications. The hydraulic pump shall meet the requirements of SAE bolt holes.
In the early 1990s, automobile engine manufacturers switched from external gear oil pumps to internal gear designs,... less

The desk should accurately fit each employee's height and office chair. Make sure there is enough space on the desk for the computer, and provide extra space for work files and supplies.
Computer desks are better than ordinary desks. The reasons are as follows:
This computer is used throughout the working day. Different from ordinary desks, computer desks are made to meet the ergonomics of using computers. The computer desk may include a sliding keyboard to provide enough space for the staff. Higher comfort will enable your employees to complete their work faster and complete tasks earlier.
Compared with ordinary desks, the reason why computer desks are indispensable in the office is based on adjustable furniture. Your employees no longer need to adjust their work locations. Now workstations can adapt to them and remain... less

How are die castings environmentally friendly?
There are many factors that make die casting the most environmentally friendly choice in metal casting. First, when you make a dice, you can use it over and over again. Other metal casting methods (such as sand casting) require you to make sand molds, which must be pressed after each casting. This wastes a lot of energy and the used sand needs to be recycled or properly disposed of.
On the contrary, a dice can be used tens of thousands of times. Similarly, die casting uses many recyclable materials. Other environmental protection measures related to die-casting can include: reusing excess die lubricant instead of letting it flow into waterways; testing for oil, grease, metal or excessive suspended solids in water, and frequently testing pH.
What are die-cast recyclable materials?
