Profession pultrusion machine operator

Pultrusion Machine Operators tend, control, and maintain machines which enable the production of composite materials with consistent cross-sections by adding reinforcement fibres such as fibreglass to the existing material and coating the resulting material with resin; this then is pulled through a heated dye where it becomes cured.

  • Types of fibre for polymer reinforcement

    Fibres used to reinforce composite materials, such as glass fibre, carbon fibre and plastic fibre. Their usage cases, costs, advantages and disadvantages, and production techniques associated with their use.

  • Pultrusion process

    The process where a cluster of fibre is coated in resin and forced through a mold, then cured with heat to produce a fibre-reinforced polymer.

  • 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.


  • 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 glass fibre into pultrusion machine

    Make sure the glass fibre material is taken in by the pultrusion machine without jams or defects.

  • Control temperature

    Measure and adjust temperature of a given space or object.

  • Optimise production processes parameters

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

  • Use personal protection equipment

    Make use of protection equipment according to training, instruction and manuals. Inspect the equipment and use it consistently.
