Operation

There are three basic functions to operate the Biostar including:

Preparation of Models

Prepare models for the thermal forming process by removing bubbles or filling voids whether

using the platform or pellets. The platform is used when forming soft or thin plastics. Pellets

are used when forming thick, less flexible materials. The pellets prevent the plastic from

forming to unwanted areas of the dental cast. In either case, the model should be placed with

the incisors facing towards the locking handle.

Use of the Platform

The platform is used to expose the entire dental mold to the formation of the thermal-plastic.

It eliminates having to use pellets. Pellets are difficult to remove from softer material (i.e.

soft mouthguard material) and can create a higher occurrence of air leaks during the pressure

forming process when using thinner thermal-plastics (i.e. < 1mm thick).

• Model preparation

• Heating cycle

• Pressure molding process

Place the pellet cup flush onto the four metal

blocks on the Biostar table. Empty cup or reduce

the pellet line to the half-way level. Make sure the

inner lip of the cup is clean. Place the outer ring of

the platform on the inner lip of the pellet cup with

the flat platform surface on top.
