A mold instrumented with RJG’s sensor technology helps to predict more accurate templates from simulation by improving upon standardized test methodology. This method offers a better comparison between test methodology and real-world molding applications. It is not meant as a replacement of standard testing, but is used in conjunction to improve simulation accuracy. This reduces the need for material characterization, allowing for significant time savings.

In-mold rheology should be considered if your project includes one or more of the following:

  • Tight tolerances or narrow validation windows
  • Material does not exist in the simulation database
  • Material characterization file is outdated
  • Material contains regrinds, colorant, or other fillers that are likely not characterized

TZERO Success Stories

“Design, quality, process, and tool launch improvements saved us time, money, and scrap. Training has provided us with better communication and decision making, a major benefit that has greatly improved the way we operate. RJG and the TZERO group have supported us with great solutions to difficult problems, allowing us to improve our relationships with our customers.”

Molding Manager
Tribar Manufacturing

“With RJG’s TZERO group we were able to identify inadequate part designs, predict molding defects, optimize mold design, and pinpoint potential assembly complications through numerous simulations. In the end, the work with TZERO provided significant improvements in all areas that will save the company an estimated $4 million per year in piece price.”

“As a result of this collaboration, we are now sequencing the injection based on sensors in the mold. Sequencing based on mold-based events, rather than time or screw position, allows a process to be responsive to actual conditions in real time.”
