The capacity of the machine is not too large because the mixture just put into the mold and not forced to go off the length of the mold.Small pressure because of high pressure gas distribution of forces throughout the mold.Improved product quality due to be filled out and fix the defects, improving the quality of the surface.The possibility of production methods are diverse products.Reduce the time of the cycle (compared to other methods when squeezing the product cócùng magnitude) and compared with special details are the same size as the special details on cooling time longer.High mechanical durability compared with special details because the weight was reduced, only the distribution of lênthành products.Reduce, eliminate the defects and warping due to keep the air pressure in the làmlạnh process.Residual stresses are small to ensure the stability of product size.-Disadvantages:The issue of copyright ownership. Relatively high production costs The method to have important implications for both the process, if the plastic nozzle and gas injection are the same then the construction very difficult.
