New Zeiger Z3 Screw-Tip Valve is Injection Molding Breakthrough 

Zeiger Industries introduces the new Zeiger Z3TM three-piece screw-tip valve.

Known for its Zeiger Z4TM four-piece screw-tip, Zeiger now offers the first advanced three-piece screw-tip valve for more affordable, best-in-class performance for general injection molding applications.

Compared to typical three-piece screw-tip valves, the new Zeiger Z3 offers longer injection molding valve life, fewer breakdowns and better value. The competitively priced Z3 outperforms all three-piece injection molding valves in achieving repeatable shot control.

Proprietary, advanced design features of the Zeiger Z3 injection molding valve include:

• Precision-crafted from D2 tool steel, hardened to 60RC (Rockwell), for good corrosion- and abrasion-resistance that far outlasts the "veneer approach" of competitors' nitrided steel

• A full-flow channel design that is self-cleaning, resulting in less downtime than free-flow valves which require cleaning between runs

• Fast-installing hex wrenching flats that simplify maintenance with no specialized tools needed

Hot Runner Balancing Now with Cavity
Pressure Sensors 

Priamus System Technologies has announced a patent-pending hot runner balancing system where the melt front in real time is not only detected quickly and reliably by temperature sensors but also by cavity pressure sensors.  

Cavity pressure sensors can now also be used for a reliable, fast and automatic switchover to holdling pressure as soon as the melt reaches the sensor. Equally molding valve gates can be opened automatically, in sequence, when the melt arrives, or venting cores can be closed automatically. 

More importantly, the new system is located on the automatic hotrunner balancing where not only temperature sensors, but alternatively also pressure sensors can be used. While the balancing of multi cavities with cavity temperature sensors is a particularly favorable and robust process, the method with cavity pressure sensors offers the possibility to monitor the melt compression. The monitoring of incompletely filled parts is with both procedures possible.

Mastercam X4: Spotlight on Lathe  

Mastercam X4 Lathe has been released with a new suite of CAD/CAM tools. From roughing and finishing to easy grooving and threading, Mastercam Lathe has been designed to reduce programmer interaction and increase machining flexibility. 

Mastercam X4 Lathe delivers a streamlined set of programming tools, including:

• “Quick Toolpaths” for programming parts with just a few clicks.

• Optimized facing including roughing and finishing.

• Complete threading with multiple starts, diameter calculation, and user customizable thread tables.

• In addition to turning, full 3- to 5-axis milling, including machines with B-axis tooling arms.

• Grooving with multiple depth cuts and pecking and more.

Mastercam’s streamlined CAD engine makes design work easier than ever before. Each piece of geometry created is “live,” letting the user quickly modify it until it’s exactly what is desired.

Diamond Textured Finger Sprue Gripper 

The Diamond Textured Finger Sprue Gripper (PB-0140) from EMI Plastics Equipment features diamond textured fingers for gripping sprues. The diamond textured fingers help to provide better "stripping" grip when sprues need to be pulled or stripped from a mold cavity. The PB-0140 has the same body and mounting options as the popular small PB14 (PB0014) model sprue gripper; the difference being that the PB14 (PB0014) has grooved fingers.
