Normally Expansion Tank is made by semi-transparent materials, such as plastic. The reason why use this kind material is that we can easily observed the liquid level directly through the box instead of opening the cap.
The operating principle of expansion tank is that, when people run cars, the temperature of the coolant circulating through the water jackets naturally increases which will increase pressure in the cooling system. When the pressure builds to a high enough point, the radiator cap allows that pressure to escape into the coolant reservoir through a small hose, called an overflow hose connected by the neck of the radiator to the expansion tank. Most of the coolant that is forced into the expansion tank returns to the radiator naturally after a few hours or when the engine is cold.
Without expansion tank, cooling systems would explode under pressure or the coolant would be forced from the overflow tube on the radiator and leak onto the road. It is advisable to check expansion tank regularly.
We can provide all kinds of expansion tank and Brake Fluid Tanks with high quality and reasonable price. As we all know, expansion tank is a vital component in our car`s cooling system.

After many years of development, China's sealing machines and other packaging machinery have become one of the ten industries in the machinery industry. Regardless of the output or output value, remarkable achievements have been made. However, there are still many problems in the packaging machinery manufacturing industry in China, such as sealing machines.
The first is the lack of macro-control. Because packaging machinery companies such as sealing machines have a low starting point, they are not "capable of talent." Cross-sector and cross-industry. There is the problem of overall planning and macro guidance. In the process of opening up new products for investment, every one of them rises up, blindly imitates, and there is a low level of repeated disorderly competition.
The second is the lack of capital investment. This is also a common feature of the machinery industry. It is difficult to attract large amounts of capital and it is difficult to hold a large number of skill reforms. Due to insufficient funds, the investment for research and development by enterprises accounts for an average of less than 1% of the amount of sales. Can not produce a generation. Develop a generation and study a generation. Because there is no skill reserve, the introduction of skills, digestion and recovery of ineffective things, so that enterprises lack high-tech products lack of market competitiveness.
The third is the lack of professional skills personnel. Because the current level of profitability of the packaging machinery industry, such as sealing machines, is widely low, it is difficult to attract good skilled personnel, resulting in a chaotic team of talents, the ability to independently develop products and innovative skills, and the ability to absorb and digest foreign products of the same kind.
In the face of various deficiencies, the sealing machine industry urgently needs to actively introduce talents and open up high-tech and new-skilled products that meet the market's needs. Create brand-name products such as sealing machines with Chinese characteristics such as packaging machines, so that China's sealing machines and other packaging machinery industry into the healthy growth track. The state shall also give appropriate support to the key projects of packaging machines and other packaging machinery in terms of policies and funds, so as to change the enthusiasm of the backbone enterprises of packaging machinery, such as sealing machines, in research and development of new products.
As engine coolant heats up, it expands. The Coolant Expansion Tank provides additional storage for the expanding coolant and is commonly the location where coolant is added to the engine.
Sealing machine industry problems escalated into intense issues
Judging from the growing trend of packaging machinery such as international sealing machines, China's packaging industry can only rely on growth funds to invest in people and expand the production scope of extensive planning has been unable to obtain the desired growth situation. China's packaging configuration and production has entered a new period of mediating product layout and improving the ability to open up. Skill upgrading, product replacement, and strengthening of handling are still the subject of intense industry growth.
