Vacuum Forming Retainer Machine
This Vacuum Former is an economical unit excellent for fabricating thermoplastic appliances. It has all-aluminum construction, a single post design, and a pellet-loaded frame. It can be used with most square and round thermoplastic vacuum former sheet materials.
Advantages:
- Suitable for round and square sheets of different materials.
-
The special ceramic heating element provides more uniform heating.
-
The unique rotating frame allows for heating on both sides of the sheets.
-
Cast rack with beads advantageous when making splints.
-
When the vacuum forming retainer machine is not in use for 10 min or more, the CUT OFF switch will turn off the unit.
Conventional Vacuum Forming Process
1. To start the vacuum forming process, raise the sheet support up to the upper limit and turn the vacuum activation handle to the right in the clockwise direction to fasten the unit. Then turn the heating unit 180º in the clockwise direction, leaving it completely facing the posterior part of the equipment.
2. Put the cast in the double-sided cast rack and then place the set in the vacuum chamber.
3. To position the sheet, turn the shorter ring in the anticlockwise direction and remove it, position the sheet and invert the process to fasten it.
4. Return the heating unit to the initial position (aligned to the sheet support) and activate the main switch to start the healing process (the red light of the main switch will go on).
5. Plasticizing Point: Due to the existence of several types of sheets, the plasticizing point is identified by changes in the sheet, runoff, or heating time. Generally, the ideal point is observed by changes or sheet runoff (10 to 12 mm).
6. Upon reaching the plasticizing point, turn the vacuum activation handle (right) in the anticlockwise direction only enough to release sheet support and then lower the entire set completely through the two handles until it is inserted in the vacuum chamber and the vacuum will start automatically.
7. Turn the heating unit again in the clockwise direction to the back part of the equipment and leave the vacuum motor on until the confirmation process is complete, which may take 10 to 20 seconds.
Warning: Do not leave the motor on for more than 1 minute to avoid overheating.
8. Turn off the main switch and allow the model to cool down.
9. Turn the shorter ring anticlockwise to release the model and remove it.
Rotary Vacuum Forming Process
1. The vacuum forming retainer machine leaves the factory with the sheet support locked to avoid accidental rotation in the conventional process. It is necessary to loosen the screw with the 4 mm Allen wrench (item 10) provided with the equipment only enough to release the set.
Attention: In this process, just place the double-sided cast rack into the vacuum chamber after the heating process is complete.
2. After releasing the movement of the rotary system, follow the steps described in the conventional system up to step 4 to heat one side of the sheet.
3. To heat the other side, turn the heating unit clockwise to the back part of the equipment and then rotate the larger ring 180º in the anticlockwise direction until you hear a “click”, and with the other side of the sheet exposed upwards return the heating unit to the initial position and wait for the heating of this side of the sheet. Attention: Never lower the sheet support when it is rotating.
4. Return the heating unit to the back part of the equipment and rotate the larger ring clockwise to the initial process position. Leave the first heated side of the sheet to heat a bit more.
5. After healing is complete, follow step 6 of the conventional process to conclude. Our Model of vacuum forming retainer machine enables two plasticizing processes, conventional and Rotary, monitored by a digital timer.
Maintenance and Cleaning
Always keep the equipment clean and free from moisture, especially the heating element located in the heating unit. The heating element must not be touched by metallic tools or objects. In case the heating element has to be replaced, it must be performed preferably by an authorized technical service. In case the power cable is damaged, it must be replaced by another with the same characteristics and certifications.
The vacuum forming retainer machine column does not require lubrication; only keep it clean and free from dust and residues.
Fuse Replacement: Disconnect the power cable from the outlet before replacing the fuse. It is highly recommended to purchase a similar fuse for replacement: Delayed actuation 5x20mm
