Personality Type

  • Realistic / Conventional
  • Realistic / Investigative


  • Coating substances

    Have knowledge of various types of coating, providing a workpiece with one or more finishing layers of resins, sugars, powders, inactive and insoluable fillers, waxes, gums, plasticisers, colouring materials, lacquer, and others.

  • Fibreglass laminating

    Process of applying multiple layers of fiberglass, a strong lightweight plastic reinforced with glass fibre woven into mats, using various techniques such as applying pressure or adhesives, welding or heating in order to provide strength and stability to the composite material. The fibreglass can also be sprayed in liquid form onto products.


  • Control glass fibres flow

    Control and adjust the parameters to maintain the appropriate pressure, temperature and flow rate of the molten fibreglass through the spray jets.

  • Optimise production processes parameters

    Optimise and maintain the parameters of the production process such as flow, temperature or pressure.

  • Monitor processing environment conditions

    Verify that the overall conditions of the room where the process will take place, such as temperature or air humidity, meet the requirements, and adjust if necessary.

  • Feed hoppers

    Feed hoppers with the required materials using various tools such as lifting equipment or shovels.

  • Tend fibreglass machine

    Tend the machine used to create fibreglass products such as lawn furniture or boat hulls by spraying molten glassfibre.

  • Extract products from moulds

    Remove finished products from moulds and examine them in detail for anomalies.

  • Trim excess material

    Trim surplus material of fabric such as fiberglass mats, cloth, plastics or rubber.

  • Remove air bubbles from fibreglass

    Use brushes and rollers to eliminate air bubbles that could weaken the fibreglass, to ensure perfect adherence of the resin to the product shell or to previous layers, and to avoid any structural defects.

  • Feed fibreglass machine

    Feed the machine with raw fibreglass according to specifications of the end-products to be developed.
