A depressible protrusion is associated with the first runner component, and a receiver is associated with the second runner component. The depressible protrusion and the receiver are positioned such that when the first runner component and the second runner component are coupled together along the first and second runner component sliding surfaces the depressible protrusion is received in the receiver, and the first and second channel apertures are misaligned. | 03-10-2016 |
20160096299 | INJECTION NOZZLE WITH MULTI-PIECE TIP PORTION - A hot runner nozzle assembly includes a nozzle heater, a hot runner nozzle, a nozzle tip, a nozzle tip seal surrounding the nozzle tip and a connecting element positioned to removably couple the tip seal to the nozzle tip and to create a first contact seal between the nozzle tip and the tip seal and a second annular contact seal between the tip seal and a mold component. The nozzle tip is made or shaped via a sintering process from a metal matrix composite (MMC) material having a first coefficient of thermal expansion. The tip seal is made or shaped from a ceramic based powder material, having a second coefficient of thermal expansion that is different from the first coefficient of thermal expansion. In operation this hot runner nozzle assembly provides an improved heat profile and a reduced leakage at the tip area under a wider operating processing window. | 04-07-2016 |
20160101550 | SINGLE NOZZLE VALVE GATE - An in-line single nozzle valve gate apparatus for injection molding comprises upper and lower rnatable annular cylinder bodies that house an annular dual sided piston having opposed pressure bearing upper and lower surfaces. The piston has a cross beam to which a valve gate pin is attached for movement therewith. The valve gate pin passes through a sprue bushing flow path to selectively open and close a part cavity gate. An interface is provided to receive molten plastic from the injection machine nozzle and pass it into the sprue bushing flow path. The cylinder bodies reside largely outside of the mold plate architecture to lessen thermal damage too piston seals. | 04-14-2016 |
