The Importance of Understanding Melt Temperature
There are four key process variables to control when molding high-quality injection molded parts: melt temperature, fill speed, pack pressure and cooling rate. Melt temperature has always been difficult to measure accurately, especially in small shot sizes — until now. There is a revolutionary new way to measure melt temperature called the Melt Temperature Measurement System, or MTMS. By accurately duplicating melt temperature, you can reduce rejects and minimize normal process variation from lot to lot and press to press.
Melt Temperature Measurement System Kit
Accurately Measure Your Purge Temperature
The Melt Temperature Measurement System gives manufacturers the ability to accurately measure melt temperature when working with injection molded parts. Here’s what you can expect with this kit:
- Safe — no hands near the purge
- Measure all shot sizes — including ones smaller than one ounce
- Repeatable from operator to operator
- Accurate within +/- 1%
- Eliminates human error
- Minimizes material waste
- Low cost per purge
- Fast — under 1-minute cycle interruption
How It Works
MTMS is based on two major principles. The first is to keep the purge molten by using an insulator cup. And the second is to precisely position the thermocouple probe in the effective flow path for shot/purge-to-shot/purge repeatability. The new Melt Temperature Measurement System is patented and manufactured by Schmit Prototypes.

It will work on all presses with a 4.000-inch diameter locating ring. If your press is different, a special spacer or collar can be made.
It works on most materials except for mineral and high glass-filled materials.
If the purge solidifies and shrinks on the thermocouple probe, damage will occur to the probe.
The purge will solidify immediately and probe damage may occur.
From ½ ounce to 10 pounds.
½ ounce or smaller depending on the cushion size.
It may not be a problem. Some materials stick to the insulator cup and the ring may stay with the nozzle when retracted and the purge puck stays with the mold. If this happens the thermocouple probe may be bent or damaged.
Both ½- or ¾-inch radius
The thermocouple probe must be positioned all the way into the insulator and stopped at the collar on the outside of the purge puck.
+/-1% on most materials.
The purge stays molten due to the insulating properties of the cup. Also, the wiping action of the flowing material going over the probe eliminates skinning on the probe. With the elimination of the skin, which is an insulator, the maximum temperature is obtained and recorded.
It can be carefully straightened.
Yes. Type K with Mini plugs.
No. We are in the development stages of designing a locating system to work. Contact Schmit Prototypes for an update.
