APPARATUS AND METHOD FOR INJECTION MOLDING AT LOW CONSTANT PRESSURE

A low constant pressure injection molding machine forms molded parts by injecting molten thermoplastic material into a mold cavity at low substantially constant pressures of 6,000 psi and less. As a result, the low constant pressure injection molding machine includes a mold formed of easily machinea...

More Information
Summary:A low constant pressure injection molding machine forms molded parts by injecting molten thermoplastic material into a mold cavity at low substantially constant pressures of 6,000 psi and less. As a result, the low constant pressure injection molding machine includes a mold formed of easily machineable material that is less costly and faster to manufacture than typical injection molds. L'invention concerne une machine à mouler par injection, à basse pression constante, qui forme des pièces moulées en injectant une matière thermoplastique fondue dans une cavité de moule à des pressions basses et sensiblement constantes, de 6 000 psi et moins. De cette façon, la machine à mouler par injection, à basse pression constante, comprend un moule formé d'un matériau facilement usinable qui est moins coûteux et plus rapide à travailler que les moules d'injection typiques.
