The Importance of Compressed Air for Injection Molding Industry
Compressed air is the second largest energy source after electricity, which has the advantages of storage, fluidity and dynamic change.It is widely used in petroleum, chemical industry, metallurgy, electric power, machinery, light industry, textile industry, automobile industry, Electronics, food, medicine, biochemistry, national defense, scientific research and other industries and sectors.
As the compressed air contain water, oil and dust which has greatly harm to it’s equipment and production , thus greatly reducing the benefits from using air compressor.
Industry Overview
Compressed air has been widely used in various departments of the national economy as a kind of high quality power source because of its storage, mobility and adaptability of dynamic change. While there is greatly harmful to equipment and production due to water, oil and dust in compressed air, thus greatly reducing the benefits to use compressed air. For example, As for pneumatic systems, the moisture in the compressed air can cause corrosion of the components, oil can cause aging of the rubber seals, dust can cause wear and blockage of the components. Above mentioned and analysis that 80% break down of pneumatic system may caused by them.On the process of application of compressed air in various industries such as chemical, pharmaceutical, food, rubber, textile, painting, communications and other hazards of gas pollution, which can not be underestimated. Modern communication cables must be filled with dry compressed air, otherwise the high frequency insulation can not guarantee the signal transmission. The quality will be declined of paint and spray for water and oil of compressed air.Compressed air water and oil will paint, spray the quality of decline, which will make a lot of chemical processes can not be implemented. As for the pharmaceutical and food industry,It’s necessary to purify compressed air.
Obviously, the purification of compressed air refers to the removal of moisture, oil and dust to achieve a certain quality level. Therefore,it is an indispensable part on the compressed air industry,although the purification equipment of air compression only an auxiliary equipment.generally, purification equipment is mainly divided into refrigeration purification equipment and adsorption purification equipment via the needs of compressed air purification,the main function of which adopts different ways to remove moisture of compressed air , while there is another separation purification equipment, it is to remove oil and dust of compressed air.
How to use compressed air in the plastic industry?
Air occupies a certain space, but it does not have a fixed shape and volume. When a pressure is applied to the air in the closed container, the volume of the air is compressed to increase the internal pressure. When the external force is removed,the air will return to the original volume under the action of the internal pressure. If there is an active object in the container, which will be pushed out by the pressure of the air inside the container when the air returns to its original volume. This principle is widely used in production and life.
What is injection molding？
It means that the material is injected into the cavity from a high pressure through melted-heat,obtaining a molded product after cool and solidify .The method is suitable for batch production of complicated parts, and is one of important processing methods.
Injection molding can be divided into the following six stages
1.Clamping
2.Injection
3.Holding pressure
4.Cool down
5.Break the mould
6.Products removed
(The process can be repeated doing to produce an injection molding.)
In the injection molding, there is also a very important role in compresses air,that is gas-assisted injection molding technology. Basically apply for all of the thermoplastics, which used for injection molding and general engineering materials (such as PS, HIPS, PP, ABS ...)
Technical principle
Gas-assisted injection molding
Clean compressed air to ensure the quality of finished products, what is the technology advantages for gas-assisted injection molding?
1, To save plastic raw materials up to 40%;
2, To save and eliminating contraction marks of product surface ;
3, To shorten the production cycle;
4, To simplify the design of complex products;
5, To reduce internal stress of product , avoid products’ deformation;
6, To reduce the pressure within the die cavity so that molding can be reduced loss and working life can be improved;
7, To lower clamping pressure of injection molding machine up to 50%;
8, To improve the working life of injection molding machines and reduce power consumption.
Biteman unit modular desiccant dryer and high precision filter---which is not only completely solve the water, oil, dust in the compressed air and other issues to provide technical support, and also greatly reduce energy consumption much than traditional purification equipment . Heat-free models need to 5% renewable gas consumption, micro-heat models only 2% the re-gas consumption, greatly reducing the energy consumption and production costs.
