As consumers, we not only pay attention to the price of such products but also hope to buy products with better quality, so as to ensure that the later use will not be affected and the service life can be prolonged. In addition, a large number of ECCA wires are required for general construction, so we must make sure how to judge the quality of such products.
Direct understanding of ECCA wire quality. Although it is also very convenient to wholesale ECCA wires through the network now, and many manufacturers will also provide us with basic types of products, the quotation is not particularly high. But if we can directly see the real things, of course we can also know how the quality of the products is. Many brand manufacturers also have their own physical... less

The use of traditional freezers needs to consume a large amount of conventional energy, causing more and more serious pollution to the environment indirectly. Judging from China's current energy supply and environmental protection needs, the development of freezers using clean energy will be the general trend. In addition, many remote areas and nomads in China have not yet been included in the power supply network and are not yet in a position to use freezers to preserve food. These also provide a potential market for the development of solar DC freezers.
However, there are also various factors restricting the wide application of solar DC freezer refrigeration technology at this stage. On the one hand, due to the low efficiency,... less
The stainless steel hose is made of stainless steel SUS304 or SUS301. It is used as a protective tube for wires, cables, optical fibers, and signal lines of automated instruments.

The force is the pressure when closing the mould, the pressure of the melt in the mould cavity and the pulling force when opening the mould, etc. The pressure of melt is the main factor. The dustbin mould generally works at a certain temperature and the temperature fluctuates.
In addition, the dustbin mould will be rubbed by plastic and possibly corroded by corrosive gas when working. The working conditions of the dustbin mould are relatively harsh. To ensure the mould has a certain service life, the dustbin mould material, especially the moulding part material, must meet certain requirements.
First, the mechanical processing performance is excellent: the steel grade which is easy to cut and can obtain high precision after processing is selected, medium carbon steel... less
