Which low voltage machine is better, air compressor is high pressure and low pressure good?

I really know one, just Quanwei Machinery, save electricity, hope.

At present, there are not many brands of low-pressure injection molding machines in China, as far as I know, there are Jintong injection molding machines and Tiansai, and our company has not used them.

Last year, our company expanded its scale and added two new production lines that are data lines, and the boss purchased 4 low-pressure injection molding machines in Jintong.

The ** of the low-voltage machine is not high, it seems to be about 20,000 units at that time, the machine is not big, because the production of data lines needs low-voltage machines to package, and two automatic soldering machines have been purchased, the work efficiency is quite high, and the supporting use is really good, reducing labor costs, and the operation is simple. At present, there is no problem, so I personally feel that Jintong's low-pressure injection molding machine is still very good.

The hot runner is heated to ensure that the plastic of the runner and gate remains molten. Because there is a heating rod and a heating ring near or in the center of the runner, the entire runner from the nozzle outlet of the injection molding machine to the gate is in a high temperature state, so that the plastic in the runner remains melted, and the runner generally does not need to be opened to take out the condensate after the shutdown, and only the runner needs to be heated to the required temperature when the machine is turned on again. For this reason, the hot runner process is sometimes referred to as a hot manifold system, or as runnerless molding.

Advantages and disadvantages of hot runner technology Compared with conventional cold runners, hot runner technology has the following advantages: 1. Save raw materials and reduce costs. 2. Shorten the molding cycle and improve the efficiency of the machine 3. Improve the surface quality and mechanical properties of products.

4. You don't need to use a three-plate mold to use a point gate. 5. It can economically form a single product with a side gate. 6. Improve the degree of automation.

7. The gate can be controlled by the needle valve gate.

The perfect solution is presented immediately.

<> air compressors are usually divided into two types: low-pressure air compressors and high-pressure air compressors, which have different application scenarios and advantages and disadvantages.

Low-pressure air compressor: The output air pressure of this air compressor is relatively low, usually between. It is suitable for some openings with large gas coverage area and low air pressure requirements, such as automobile painting, furniture spraying and other industries.

The cost of low-pressure air compressors is relatively low, and maintenance is relatively easy.

High-pressure air compressor: The output air pressure of this air compressor is relatively high, usually between 3-40MPa. It is suitable for some occasions with high air pressure requirements, such as bottled water, aerospace and other industries. The working efficiency of the high-pressure air compressor is higher, and higher air pressure and flow can be achieved.

In general, low-pressure air compressors and high-pressure air compressors have their own application scenarios and advantages and disadvantages, and it is necessary to select the appropriate air compressor model according to the specific needs and working environment.

1. Which brand of air compressor is the best to use?

The mid-to-high-end air compressor is basically monopolized by foreign brands, mainly:

Taiwan Jaguar. Atlas.

Sullair Ingersoll Rand.

These are all international brands, and the whole machine is relatively expensive.

Domestic ones such as: Taiwan Jaguar, Liuzhou Fidelity, Bolaite are not bad, the whole machine is relatively cheap.

2. The question of cost performance.

Mainly from the brand, purchase costs, maintenance costs, use costs to synthesize.

In terms of brand, I think you should buy Midea, Midea's brand is better.

Personally, I think Gree's air compressor is a little easier to use, the quality is also very good, and it is not very expensive.

Compair DeMag (compair) Compair is a British company known primarily for the production of sliding vane compressors (50 hp). At present, there is no information showing its profit**.

The public said that the public was reasonable, and the mother said that the mother was reasonable, and they were all buying flowers and praising the fragrance of flowers. Liufuda Bolaite's domestic brands are subsidiaries of Atlas, the cost performance is quite good, the price is relatively high, Kaishan is a domestic brand with independent intellectual property rights, ** cheaper, relatively high reputation, others include a lot of self-assembled OEM more, not one by one. Know.

I sell Ouhua's, which is not well-known, domestic, and cost-effective.

I think the domestic air compressor Haier brand is very cost-effective, intelligent and cost-effective, intelligent and high.

There are 3 screw air compressors of China's own brand, the earliest domestic production of screw host enterprises, is also a listed company, several domestic companies just started to develop screw host when it was not very mature, in recent years it is getting better and better, the research and development of two-stage compression host is more energy-saving, replacing imported brands, the quality is becoming more and more stable, it is recommended to use domestic brands, of course, there are innovative research and development capabilities in the domestic enterprises. At present, there are 3 best screw air compressor brands in China, Bowes, Hanbell (Taiwan), Kaishan, all three are listed companies, Hanbell started early in 1998, followed by Kaishan was established in 2002, and finally Bowes was established in 2005, the annual operating income of the three companies is about 1.5 billion yuan, Hanzhong's main business is refrigeration compressors, Kaishan's main business is construction and mining machinery compressors, Kaishan has a lot of low air compressor quality, Bowes's main business is screw compressors, and vacuum pumps, Bowes has the momentum of catching up and surpassing the other two, especially in recent years, Bowes has taken the lead in launching the two-stage compression screw host, which is more energy-saving, stable in quality, and has won unanimous praise in the market.

Foreign low-voltage electrical brands: Schneider, ABB, Siemens.

Local low-voltage electrical brands: People's Electric, Delixi, Zhengtai, Tianzheng (these electrical brands are well-known low-voltage electrical brands that have participated in international large-scale projects.) The quality of the products is leveraged, especially the people's electrical appliances, which mainly provided high-quality electrical products for major engineering projects, and began to enter the homes of ordinary people in recent years.

The product strength is strong).

Whether you want to join or want to buy low-voltage electrical appliances, I recommend that you choose domestic products, first of all, some foreign brands have withdrawn from China, resulting in the quality of the products produced is not as good as before, although the brand's reputation is there, but the quality does not match the first. But local brands are different, in recent years, local brands have been catching up and learning, in terms of function, quality, safety performance have narrowed the gap between foreign brands, and some product performance is even better than foreign ones. The current domestic low-voltage electrical products can be regarded as cost-effective electrical products.
