Laminators responsible for laminating high performance composite components
Release air bubbles and smooth seams, using rollers. Select precut fiberglass mats, cloth, and wood-bracing materials as required by projects being assembled. Select production input materials. Spray chopped fiberglass, resins, and catalysts onto prepared molds or dies using pneumatic spray guns with chopper attachments. Place materials into molds. Pat or press layers of saturated mat or cloth into place on molds, using brushes or hands, and smooth out wrinkles and air bubbles with hands or squeegees.
Mix catalysts into resins, and saturate cloth and mats with mixtures, using brushes. Mix substances to create chemical solutions. Apply water or solutions to fabrics or apparel. Apply layers of plastic resin to mold surfaces prior to placement of fiberglass mats, repeating layers until products have the desired thicknesses and plastics have jelled. Apply parting agents or other solutions to molds. Bond wood reinforcing strips to decks and cabin structures of watercraft, using resin-saturated fiberglass.
Check completed products for conformance to specifications and for defects by measuring with rulers or micrometers, by checking them visually, or by tapping them to detect bubbles or dead spots. Measure dimensions of completed products or workpieces to verify conformance to specifications. Mask off mold areas not to be laminated, using cellophane, wax paper, masking tape, or special sprays containing mold-release substances. Apply lacquers and waxes to mold surfaces to facilitate assembly and removal of laminated parts. Apply parting agents or other solutions to molds.
Check all dies, templates, and cutout patterns to be used in the manufacturing process to ensure that they conform to dimensional data, photographs, blueprints, samples, or customer specifications. Inspect production equipment. Inspect, clean, and assemble molds before beginning work. Inspect production equipment. Clean production equipment. Build production molds. Trim excess materials from molds, using hand shears or trimming knives. Trim excess material from workpieces. Repair or modify damaged or defective glass-fiber parts, checking thicknesses, densities, and contours to ensure a close fit after repair. Repair parts or assemblies.
Cure materials by letting them set at room temperature, placing them under heat lamps, or baking them in ovens. Load items into ovens or furnaces. Trim cured materials by sawing them with diamond-impregnated cutoff wheels. Trim excess material from workpieces.
