The beneficial effects of the invention are as follows：
1. smooth surface plastic cement product can be made：During injection and pressurize are carried out, die surface keeps high temperature, can
To form smooth surface, the plastic cement products of light-emitting area can be more done；
2. due to the high temperature of die surface in injection process, glass fibre, carbon fibre and miberal powder enhancing can stablize molten
The inside of glue, keep the apparent property of moulding；
3. during high-temperature molding, the surface crystallization ratio increase of product, the physical property of product improves；
4. surface can realize high-precision embossing work.
