Accu-Valve™ CX and Accu-Valve™ EX precision valve gate products from Mold-Masters Limited (Georgetown, ON) were designed to address the challenge of valve gating of commodity and engineered resins together with a wide range of valve actuation options. Hydraulic, pneumatic and syncro designs of valve actuation units minimize cavity spacing and overall mold size. Small profile nozzles are utilized to access smaller parts or difficult to reach gating surfaces. The Accu-Valve CX (for commodity resins) utilizes open flow channels in its patent pending design, providing accelerated melt flow and dispersion with virtually no dead or blind spots in the constant guiding mechanism. This dramatically accelerates color change versus conventional cylindrical valve gate systems, critical in high cavity packaging and personal care applications. The precise alignment of the liner and continuous engagement with the pin assures pristine and durable gate performance. The Accu-Valve EX (for engineered resins) provides precise gate area thermal conditions to ensure no pin resistance to closing while still maintaining exact alignment between pin and cavity insert. This design ensures that thermally sensitive resins maintain their properties by being processed at temperatures recommended by the material supplier, with minimal resin shear.
