The Cavex VacuFormer is a no-nonsense all-around thermal vacuum former. This robust machine has an electric high-performance vacuum motor that is suitable for any conventional pressure forming process. The Cavex VacuFormer is easy to operate and protected against overheating. The Starter kit equips the dental professional with all the equipment and materials needed to create ready-to-use pressure-forming appliances.

Cavex VacuFormer Laminates

Combine Cavex VacuFormer thermal vacuum system and VacuFormer laminates to produce perfectly fitting individual bleaching trays. VacuFormer laminates are made of soft, clear material (EVA) which is easy to cut and finish. The wide range of deep drawing plates also offers products for making mouthguards and splints.

Cavex Instant Stone

Casting perfect gypsum molds in just 10 minutes!

Many dental clinics lack a separate area for pouring dental impressions and only a few clinics use a gypsum (vacuum) mixer. Cavex Instant Stone is a gypsum composite to cast perfect molds for bleaching trays, splints, and mouthguards in just 10 minutes. Treatments that usually require multiple dental visits can now be performed in just one session. Cavex Instant Stone increases clinic productivity and improves the patient experience worldwide.

  • Instructions For Use

  • Protocols

  • Servicepartners

  • Cavex VacuFormer

  • There is no power when the machine is switched on? Heating or vacuum do not light.

    Check the power supply, the mains lead and/or the fuse.

  • The heating element stays cool when the main switch is switched to heating?

    Make sure that the timer is switched on. Dial to the required time setting. Possibly the overheating protection is activated. Allow the element to cool and then try again.

  • The vacuum motor does not work when the switch is set to vacuum?

    Possibly the overheating protection is activated. Allow the element to cool and then try again.

  • There are two Allen keys in the accessories. When to use them?

    The Allen keys can be used to adjust the sliding of the tray holder. This can be necessary after long term use.

  • There are two red gaskets in the accessories. When to use them?

    The gaskets can be used to increase the vacuum power. The outer holes will be shut off, so the vacuum power is more concentrated to the center. This can be necessary in a situation that cast model does not have a flat bottom surface resulting in poor adaptation to the perforated plate.

  • Cavex VacuFormer Laminates

  • How do I avoid the laminates from tearing or stretching too much?

    This can happen when the laminates become too hot. The problem can be prevented by preheating sufficiently and swiveling the heating element to the rear in time. Decrease the heating time.

  • How do I avoid the laminates to become too thin at the incisal edges?

    This is often caused by a cast model being too high or by placing the cast too much centered on the vacuum plate. Trim the cast to a height of 2.5 cm maximum and/or place the anterior part closer to the center.

  • The vacuumed mould shows insufficient details. How to improve this?

    This is often the result of insufficient heating or too short a vacuum time. Preheat for sufficient time until the heating elements are ‘red’. Maintain sufficient vacuum time (┬▒ 30-60 seconds).

  • The laminates got stuck in the holes in the vacuum plate?

    Unscrew the plate, remove and empty the holes. Use a thin instrument, a probe for example, to remove the material out of the holes. Place vacuum plate back in its original position.

  • How to avoid the laminates to get stuck in the holes in the vacuum plate?

    Overheating softens the sheet so much that is sucked into the vacuum plate holes during the vacuum process. Prevent overheating.

  • How can I combine two laminates?

    Despite there are more options, the one below is most preferable.
    – Make a vacuum model with the first laminate and then repeat the process with the second laminate. Make sure that the laminate is clean in order to obtain proper adhesion(clean with alcohol 70%).

  • What are the dimensions of the different laminates?

  • Why is the mouthguard laminates labeled with Cavex on one side?

    This is to indicate the harder (outer) part of the tray material. This side must be up when the laminate is fixed in the tray holder.

  • Why is the splint laminate protected with blue foil?

    his is to protect the clear material from scratching. Remember to remove the blue foil from both sides of the laminate prior to use.

  • How can laminate rupture when vacuumed over the cast model?

    Check the cast model and remove sharp edges.

  • Do Cavex laminates contain latex, gluten or Bisphenol-A (BPA)?

    (Soft) EVA

    Ethylene vinyl acetate (also known as EVA) is the copolymer of ethylene and vinyl acetate. The weight percent vinyl acetate usually varies from 10 to 40%, with the remainder being ethylene. It is a polymer that approaches elastomeric materials in softness and flexibility, yet can be processed like other thermoplastics. The material has good clarity and gloss, barrier properties, low-temperature toughness, stress-crack resistance, hot-melt adhesive water proof properties, and resistance to UV radiation. EVA has little or no odor and is competitive with rubber and vinyl products in many electrical applications.

    EVA does not contain bisphenol-A (BPA), Latex or gluten.


    Poly(methyl methacrylate) (PMMA) is a transparent thermoplastic, often used as a light or shatter-resistant alternative to glass. It is sometimes called acrylic glass. Chemically, it is the synthetic polymer of methyl methacrylate. The material was developed in 1928 in various laboratories, and was first brought to market in 1933 by Rohm and Haas Company, under the trademark Plexiglas. It has since been sold under many different names including Lucite and Perspex. PMMA is an economical alternative to polycarbonate (PC) when extreme strength is not necessary. Additionally, PMMA does not contain the potentially harmful bisphenol-A (BPA) subunits found in polycarbonate. It is often preferred because of its moderate properties, easy handling and processing, and low cost, but behaves in a brittle manner when loaded, especially under an impact force, and is more prone to scratching compared to glass.

    Acrylic does not contain bisphenol-A (BPA), Latex or gluten.
