Quality characteristics of thin-walled plastic injection parts
The development of plastic injection product as consumer products, such as communication and electronic products have a tendency to be light, thin, short, and small. For example, a laptop computer product requires a smaller, variable and convenient style. Therefore, the shapes of laptop are changing...

The development of plastic injection product as consumer products, such as communication and electronic products have a tendency to be light, thin, short, and small. For example, a laptop computer product requires a smaller, variable and convenient style.
