Summary: | A low constant pressure co-injection molding machine forms molded parts by injecting molten thermoplastic material into a mold cavity at low constant pressures of 6,000 psi and lower. 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. Co-injection of thin-walled parts having an L/T ratio ]100, with embedded sustainable materials, such as polylactic acid (PLA), starch, post-consumer recyclables (PCR), and post- industrial recyclables (PIR) isolated from surfaces by barrier layers of leach-resistant material having a thickness less than 0.5mm, is possible. The co-injection molding machine is provided with a screw comprising a material having an average thermal conductivity of more than 30 BTU/HR FT �F. |
