 Plastic Injection Molding App Note.pdf |
| GOAL Monitoring the separation between two halves of a clamshell mold.Meeting critical shape tolerances for the mold dimensions.Minimizing the plastic used to avoid excess waste.Making measurements in a harsh and contaminated environment. SOLUTIONS Non-contact position sensors are mounted on the outside of the clam shell mold (see Figure 1) for real-time monitoring of the molding process. The sensors provide analog signals proportional to the separation. That means a set point can be triggered to warn when out-of-tolerance conditions are reached. Result: Improved part quality and reduced process costs.
THE KAMAN ADVANTAGE Enhanced process control. The system provides on-line control of the molding process through real-time monitoring. Minimized downtime. The system continually monitors the mold process conditions; process adjustments, shutdowns and maintenance can be conducted on an as-needed basis. Non-contact. Using eddy current technology, the sensor can measure position without ever touching the target. The result is an extremely reliable system with no moving parts.

Plastic Injection Molding Wall Thickness |
Plastic Injection Molding Wall Thickness App Notes.pdf |
| GOAL Measure the wall thickness of a plastic part as it is being molded.Keep the wall thickness (or part dimension) uniform.Minimize the plastic used to avoid excess waste.Make measurements in a harsh environment. SOLUTIONS The sensor is embedded and sealed into the outer mold (see Figure 1). To determine thickness, the sensor measures the gap between the mold and the core for comparison with the finished part specification. The KD-2306 and KDM-8206 digital signal conditioners capture thickness data on every part, providing 100% quality control. Result: Optimal wall thickness is attained and defective parts are identified.
THE KAMAN ADVANTAGE Easy-to-use. The KD-2306 and KDM-8206 are easy to configure and re-calibrate in the field with its Windows®-based software. Rugged. The sensor can withstand pressures up to 20,000 psi and temperatures to 400 °F. On-line. Kaman’s sensor measures the thickness of the plastic as the part is being molded, so defects are discovered before the product is ejected and packaged. Non-contact. Using eddy current technology, the sensor can measure the position of the inner core through the plastic without ever touching it. The result is an extremely reliable system with no moving parts. Accurate. The KD-2306 and KDM-8206 actively compensate for the temperature shifts of a molding environment resulting in accurate readiness between start-up and run conditions. Every application is unique. |
