Thermal Processor Model TPX 201

GENERAL DESCRIPTION: Branson
Thermal Processing Systems are
designed for heat staking, thermal
insertion, swaging, degating, and
date stamping.
THERMAL STAKING: In thermal
staking, also referred to as "heading or
riveting," the controlled flow of molten
plastic is used to capture or retain
another component, joining plastic to
plastic, metal, or any other type of
material (e.g., printed circuit boards).
BENEFITS OF THERMAL STAKING/
SWAGING: t
• Excellent cosmetics.
• Does not cause damage to
fragile electronic or other sensitive
components.
• Minimal tool wear.
• No flash or particulate are created.
• Extremely tight stakes created.
• Most thermoplastic materials easily
staked/swaged.
• Stake one or multiple stakes on
multiple planes simultaneously.

• No cracking, splitting, breaking, or
stresses applied to bosses.
THERMAL INSERTION: In thermal
insertion a metal insert is placed in a
boss or hole which is slightly smaller
than the insert. This hole provides a
certain degree of interference and also
serves to guide the insert into place.
The heat from the thermal tip travels
through the insert to the interface of the
metal and plastic. Heat generated by the
thermal tip causes the plastic to melt,
and as the thermal tip advances, the
insert is imbedded into the plastic component. The molten plastic flows into
the serrations, flutes, or undercuts of the
insert, and when the heat source
retracts, the plastic resolidifies and the
insert is securely encapsulated in place.
BENEFITS OF THERMAL INSERTION:
• Multiple inserts at different levels can
be seated or driven simultaneously.
Practically no limit on quantity, size,
or plane of the inserts.
• Different sized inserts can be driven
simultaneously.
