Precision Casting, Maximum Flexibility
Z4 Universal Rapid Cast Investment is engineered for dental labs that demand precision, speed, and complete control over their casting schedule. Suitable for use with all alloys and pressable ceramic systems, Z4 delivers reliable results whether you're using a high-speed or traditional overnight burnout technique.
The fine grain, phosphate bonded formula offers a smooth, creamy consistency with ample working time for multiple, bubble free pours. With Z4, rings can be placed into a hot furnace immediately after bench set - or hours or even days later - without compromising integrity. No rewetting, no cracking, no scheduling stress.
Z4 gives technicians the flexibility they need without sacrificing the consistency and accuracy modern restorations demand.
