New valve gates for prototype and production volumes.


New valve gates for single-cavity or prototype molds and for production molding of commodity or engineering materials have arrived from Mold-Masters Ltd., Georgetown, Ont. Its Accu-Line pneumatic valve gates for single-cavity and prototype molds supports the firm's Centi, Deci, and Hecto nozzles. Features include up to 60-mm lower clamp-plate height, simplified valve-pin maintenance, and valve-pin anti-rotation option.

Mold-Masters also rolled out its Accu-Valve CX valve gates for production of commodity products and Accu-Valve EX designs for engineering resins. Both series can be actuated ac·tu·ate

 with hydraulics hydraulics, branch of engineering concerned mainly with moving liquids. The term is applied commonly to the study of the mechanical properties of water, other liquids, and even gases when the effects of compressibility are small.  or pneumatics pneu·mat·ics  
n. (used with a sing. verb)
The study of the mechanical properties of air and other gases.

 and come with small-profile nozzles for smaller parts or hard-to-reach gating surfaces. The CX series uses open flow channels that provide fast melt flow and dispersion with virtually no dead spots Dead spots are abnormally fast decays of the fundamental tone on stringed instruments and are caused by a damping of the string's vibrations at a given note, due to energy transfer from the string to the instrument body. .

 valve gates. The EX series reportedly ensures no pin resistance to closing, and maintains exact alignment between the pin and cavity insert. This ensures that sensitive resins are processed at proper temperatures with minimal shear. Tel: (905) 877-0185 * www.moldmasters.com
