  • RTS  

    RTS “Reconfigurable Tooling Systems” are a paradigm shift in tooling for prototype or short-run manufacturing. RTS creates a tool from a part or pattern at room temperature that can be subsequently hardened for high-temperature use. RTS tools can be used once, many times, or stored indefinitely. When no longer needed they can be returned to a “slurry” state and reformed into new tools.

      RTS features:
    • Immediate pattern duplication
    • Tool creation for prototypes or production
    • Re-formable again and again

    Immediate pattern duplication

    Tool creation for prototypes or production

    Re-formable again and again

    Patterns can be copied in minutes and use immediately for low pressure forming processes such as wet-layup of composites. The formed bed surface can be heated to harden it for vacuum-bag, autoclave processing or even casting of metals such as zinc and aluminum alloys.

    RTS is ideal for making transfers splashes, rapid prototype tooling and multiple mold shapes for similar part geometries

      Typical applications include:
    • Fabricating parts, molds or transfer splashes at temperatures to 350oF.
    • Composite material hand-layup, vacuum bag or autoclave cure of dry fabric or pre-preg; for production or repair.
    • Resin transfer molding (RTM, VARTM, LRTM, etc.)
    • Vacuum forming molds.
    • Bonding and assembly fixtures, vacuum holding fixtures.
    • Part holding fixtures for inspection.

  • PhaseLok™

    PhaseLokTM is family of rigid casting materials to create soluble “wash-out” mandrels, especially suited for high-temperature fabrication of composite structures with trapped features.

    PhaseLok is provided ready to use as a water-based damp mix. It is odorless, non-toxic and environmentally friendly.

    Consolidated mandrels are structurally stable yet can be rapidly washed away using tap water even after exposure to processing temperatures in excess of 750oF

      PhaseLokTM key characteristics:
    • Lightweight
    • Single component
    • Machinable, repairable
    • Accurate reproductions
    • Zero shrink upon consolidation.

    Contact us for specific product data sheets: info@fovean.com

      Applications include:
    • Internal mandrels for fabricating ducts, pressure vessels and tubular struts.
    • Zero-shrink splashes for drape forming and vacuum forming
    • Hardened stamping dies when densified with resin and cured after original consolidation.
  • Tooling &s; Manufacturing Expertise  

    Fovean fabricates tooling and structures of a variety of non-metallics:

    • Advanced composites (vacuum bag / wet-layup, oven cure / prepreg, closed-mold, RTM, etc.)
    • Unreinforced plastics (epoxy, silicone, urethane)
    • Syntactic materials (custom and off-the-shelf)
    • Core materials (foam, honeycomb, non-wovens, elastomerics)
    • Wash-out and melt-out cores &s; mandrels (water soluble to eutectic alloys).
  • Wide Range of Markets  

  • Summary

    In one aspect, systems and methods are disclosed for performing health diagnostics by inducing vibrations in a first body object using a vibratory transducer; picking up at a receiver vibrations transmitted by the vibratory transducers;capturing vibrations from a second body object and comparing the captured vibrations against a database of known tissue characteristics; and generating a health diagnostic.

    In another aspect, systems and methods are disclosed for performing diagnostics by inducing vibrations in a first dental object using a vibratory transducer; picking up at a receiver vibrations transmitted by the vibratory transducers;capturing vibrations from an second dental object and comparing the captured vibrations against a database of known dental characteristics; and generating a dental diagnostic.

    In another aspect, a method of acquiring internal and external structures of tissues and restorations includes emitting vibrations and analyzing the response of those vibrations utilizing a database of known responses of different types of tissues, restorations and disease states.

    In yet another aspect, a diagnostic system includes a solenoid or transducer for emitting vibrations into the surrounding tissues; a means by which the solenoid is attached to the tissue; a power source for activating the movement of the solenoid; an amplification means for changing the frequency of solenoid; a transducer for picking up vibrations from the tissue or dental components; a computer data base of known restorative, disease and healthy states; a software means of comparing vibrations to data base, a computer means for converting data into interpretable displays.

    Advantages of the preferred embodiments may include one or more of the following. By using the disclosed data analysis method, a doctor office or a dental office can add a new method of collecting and analyzing patient information. Patients can be assured that there is quantitative, objective information. For most tissue or dental conditions, a vibration pattern can be obtained and compared against known dental conditions. The system supplies adjunctive information by which the practitioner may make a better decision regarding treatment alternatives. The system helps practitioners in determining if tissue, teeth or tooth structure is cracked, from disease or overloading; locating perforations through a tooth during root canal therapy, or during restorative procedures; determining key locations to place pins so as to select areas that will minimize the chance of cracking the tooth, or to minimize the possibility of causing nerve damage; determining, once a pilot hole has been made whether an opening into the nerve has inadvertently been made; testing sealants for leakage or decay; and identifying hidden pit caries. The system can establish objective readings or findings which can be used as a baseline recorded in a patient's chart for future comparisons. The system can be used to help differentiate between enamel, dentin, sclerotic dentin, reparative dentin, thin or weak dentin, carious pulp exposures, iatrogenic pulp exposures, perforations, major canals, accessory canals, cracks, fissures, craze lines (and their length, direction and potential for problematic cause). The system also can determine if a filling material, base or cement had been adequately cured or sealed, prior to conclusion of a treatment. The system can work with or obviate the need for x-rays while providing superior diagnosis of tissue conditions. Appropriate measurement yields tremendous information to the dentist. This information improves diagnosis, aids in better treatment, and allows for earlier detection of problems.
