Baking. The
prolonged application of heat intended to achieve
either a specific temperature or a specific result.
Bonding. The
reaction within an adhesive, generally created by
heating, resulting in the desired adhesion.
Burn-Off. The
process of heating typically fixtures coated with
paint or powder to oxidize and remove the coating.
Crosslinking. The
forming of networks if connected molecules between
molecular chains, typically generated by the application
of heat.
Curing. A
term commonly used to describe a reaction within a
coating or polymer, generally caused by heating, resulting
in the desired finish. In powder coating, curing refers
to the crosslinking or polymerization of the coating.
In latex, curing refers to the vulcanization of the
polymer.
Dip
molding. Typically the process of preheating,
dipping, and curing plastisol to form plastic caps,
plugs, grips, and handles. Also applies to dipping
of latex for the manufacture of gloves and condoms.
Drying. The
removal of moisture typically in the form of water
or solvent.
Embossing. The
process of impregnating an image into a material,
typically after the application of heat to soften
the material.
Flash-Off. The
time after the application of a solvent based coating
but before the application of heat when the light
solvents evaporate from the coating.
Fusing. The
gelling or melting of a powder coating into a liquid
film.
Gelling. The
fusing or melting of a powder coating into a liquid
film.
Glazing. The
process of drying the moisture and melting a ceramic
first into a porcelain, or glass-like surface.
Homogenizing. The
heating of cast aluminum to a temperature necessary
to change the chemical bonds, but not hot enough to
remelt the aluminum.
Laminating. The
process of clear coating a product or material with
a sheet of material.
Polymerization. The
chemical reaction combining small molecules into large
molecules.
Preheating. The
application of heat to a part in advance of an additional
process step. For example, the preheating of a mold
before dipping it into plastisol in the dip molding
process.l
Rotational
Molding. The process of dispensing material
into a mold, closing the mold, rotating the mold while
applying heat, rotating while cooling, then opening
the mold to remove the molded part.
Thermoforming. The
process of molding plastic typically through the application
of heat, pressure or vacuum, and cooling.
Vulcanizing. The
crosslinking or polymerization of a latex or rubber
polymer with heat and pressure.
