Abstract
Cellular product by injection and manufacturing method thereof, which method comprises: preparing a mixture of main material; preforming a piece of auxiliary material of different property than that of the main material mixture; forming an auxiliary cavity region in a mold cavity; place the main piece of material in the cavity; maintaining the mixture and auxiliary material mixture in the cavity at a predetermined temperature and pressure for a predetermined period and opening the mold to remove the product. Consequently, products with various properties such as color, density and hardness can be easily and efficiently achieved. (Machine-translation by Google Translate, not legally binding)
