Advantages of Plastics
Easy to process and manufacture (easy to shape)
Even if the geometry of the product is rather complex, it is easy to make as long as it can be demoulded from the die. Therefore, its efficiency is far superior to metal processing, especially injection moulding products, through a single process, can produce very complex finished products.
It can be colored at will or made into transparent products as required.
Plastics can be used to make multicolored, transparent and beautiful products. It can also be colored arbitrarily. It can improve the value of its products and give people a lively feeling.
It can be made into light weight and high strength products.
Compared with metal and ceramic products, they are light in weight, good in mechanical properties and high in strength (ratio of strength to density), so they can be made into light and high strength products. Especially when glass fiber is filled, its strength can be improved.
In addition, because of its light weight and energy saving, its products are becoming lighter and lighter.
Non-rusting and non-corrosive
Plastics are generally resistant to the corrosion of various chemicals and will not rust or be corroded as easily as metals. There is no need to worry about the erosion of acids, alkalis, salts, oils, medicines, dampness and moulds.
Not easy to heat transfer, good heat preservation performance
Because of its high specific heat, low thermal conductivity and difficulty in heat transfer, plastics have good heat preservation and insulation effect.
It can make both conductive parts and insulating products.
Plastic itself is a good insulating material. At present, it can be said that no electrical products do not use plastic. But if the plastic is filled with metal powder or debris to form, it can also be made into a product with good conductivity.
Excellent shock absorption and silencing performance, good light transmittance
Plastics have excellent performance of shock absorption and noise reduction. Transparent plastics (such as PMMA, PS, PC, etc.) can be used to make transparent plastic products (such as lenses, labels, cover panels, etc.).
Low manufacturing cost
Plastic raw materials themselves are not so cheap, because plastics are easy to process and equipment costs are relatively low, so product costs can be reduced.
