Abstract: A mold-tool system (10), comprising: a first component (12) defining a first passageway (13) configured to convey, in use, a flowable molding material; a second component (14) defining a second passageway (15) configured to: (i) be in fluid communication with the first passageway (13), and (ii) convey, in use, the flowable molding material. A wear-resistant assembly (16) contacts, at least in part, the first component (12) and the second component (14).

Abstract: A mold-tool system (100), comprising: a nozzle tip assembly (200) having a tip-body assembly (206), the tip-body assembly (206) being configured for reduced axial tilting, at least in part.

Abstract: A mold-tool assembly, comprising: a heater being configured to heat (in use), at least a portion of a component, the heater having a resistive element being encased, at least in part, in aluminum nitride.

Abstract: Disclosed is a safety connector (100; 200; 300) for a hot runner (600) having a valve stem (104) and an actuation assembly (102), the safety connector (100) including: a shear member (106) releasably interlocking the valve stem (104) with the actuation assembly (102), once the shear member (106) has interlocked the valve stem (104) with the actuation assembly (102), the valve stem (104) becomes movable in response to movement of the actuation assembly (102), and the shear member (106) being configured to shear destructively, and responsive to a predetermined undesired force acting on the shear member (106), the shear member (106) shears and the valve stem (104) becomes released from the actuation assembly (102).

Abstract: A cam and cam follower apparatus translates linear cam bar movement to perpendicular valve stem actuation in an injection molding system. The cam bars reciprocate up and down on linear bearing rails such that an actuation plate, fitted with a plurality of valve stems, is cycled normal to the direction of the cam bar movement via cam followers traveling within cam slots in the cam bars. The cam slots in the cam bars are profiled such that the cam followers affect the speed and force at which the valve stems travel while at the same time reducing frictional effects and their associated power requirement. The cam followers of the valve stem actuation plate travel in cam slots in the cam bars from a valve stem forward position, to a valve stem retracted position and ultimately, the entire actuation plate may be removed from the cam bars for maintenance via open ended slots in the cam bars.

Abstract: Disclosed is a safety connector for a hot runner having a valve stem and an actuation plate, the safety connector including: (i) a latch releasably interlocking the valve stem with the actuation plate so that in response to movement of the actuation plate, the valve stem becomes movable; and (ii) a latch mover being cooperative with the latch, and the latch mover being configured to move the latch responsive to a predetermined force acting on the valve stem so that so that the valve stem is released from the actuation plate.

Abstract: Disclosed is a nozzle tip, having a tip insert attached to a nozzle tip outlet end of a nozzle tip body, the tip insert being made of a material, or having a thermal barrier coating, having a thermal conductivity value of K<10 W/m ° K, and having a lower thermal conductivity than that of the nozzle tip body, to preclude the conduction of excessive heat to the nozzle tip outlet end, and promoting a more decisive fracture of the solidified resin at a gate orifice upon ejection of a molded product, thereby eliminating a string of molten resin and a vestige of excessive height, both of which are undesirable, on the molded product.
