A thermoplastic
polymer is one which melts or flows when heated. Thermoplastic polymers
are usually not highly crosslinked, and act much like molecular solids: low melting and boiling
points, high ductile strength.

Insert molding
is the process of molding plastic around preformed metal inserts.
Moldtronics is a pioneer in the field, having produced some of the first
parts using this process back in 1957.
This process is compatible with both thermoplastic and thermoset
materials. |
A thermoset polymer
is one that doesn't melt when heated. Thermoset polymers "set"
into a given shape when first made and afterwards do not flow or melt,
but rather decompose upon heating. They are often highly crosslinked
polymers, with properties similar to those of network covalent solids-
i.e., hard and strong.
