No, you can only process material with a diameter of 125 mm in SCHEU-DENTAL pressure moulding machines. Make sure to use the correct material size to avoid any problems during pressure build-up. The rim of a too small blank gets pulled out from the clamping of balancing and locking ring. Thus, a precise and correct thermoforming result is not ensured.

Maybe there is a pellet on the edge of the model cup between material and clamping ring. Interrupt the thermoforming process, taking care the model cup rim is absolutely clean before closing the pressure chamber.

Leaking of air usually does not affect the thermoforming result, because the compressor is constantly supplying air. Nevertheless, you should check the following:

When working on the model platform,

ensure the model is placed flush with the surface of the model platform. If it's not, trim the model flat or embed it into the pellets.

sharp edges may have damaged or torn the material. If this is the case, remove the sharp edges on the model.

the material may have moved when being clamped. In this case, clamp a new blank and restart the thermoforming process.

the balancing ring may have got stuck. In this case, remove the balancing ring, clean, grease and reinsert it. Ensure it is freely movable!

When embedding the model into the pellets, sharp model edges may cause perforation mainly of thin material.

No, this is not possible. However, depending on the series of your pressure moulding device, you can set an individual heating time using the “clock” symbol on the keyboard of your device or by using the “+” and “-” buttons. Please refer to the manual of your device to find out which option applies to your device. The operation manual of the current series of our pressure moulding machines can be found on this site under "Further Information" for download. Operation manuals of previous device series are available under SERVICE on top of this web site.
