RJG, Inc. products

Cavity pressure sensors allow you to build a process around what is actually happening inside the mold. Pressure data can also help identify common molding problems, such as shorts, dimensions, sinks, flash, warp, and more.

Temperature is critical to the manufacturing of many parts, especially those made with semi-crystalline materials or with tight dimensional tolerances. Changes or breaks in cycle time, clogged cooling lines, or improper cooling settings can dramatically impact thermal stability. In-cavity temperature sensors can help you diagnose problems and prevent shipping bad parts.

3 mm Press Fit Cavity Temperature Sensor. The Press Fit Cavity Temperature Sensor is a tool used to analyze temperature variation inside the actual mold cavity. These sensors work in conjunction with RJG’s process control systems to assist molders in diagnosing processing problems relating to temperature issues. The temperature of both the melt and mold make up two of the four plastic variables that determine how a part is formed. The Press Fit Cavity Temperature Sensor is simple to install. Simply drill a small hole for the wire and a flat bottomed pocket with the tolerance necessary to press fit the device in from the cavity face.

1 mm Flush Mount Temperature Sensor. The 1 mm Flush Mount Temperature Sensor is a tool used to analyze temperature variation inside the mold cavity. It is small enough to be installed in both small, simple molds and large, complex molds. This sensor also has a machinable tip, allowing for contouring to a mold’s surface geometry.

Mold Deflection Sensors measure how much the mold parting line opens on each cycle, helping to detect problems like properly set clamp tonnage, flash, or even gas traps if vents are collapsed from over-clamping. They can also be used in applications where cavity pressure sensors won`t fit.
