How does hot plate welding work? Click here for an overview of the hot plate welding process.
Hot plate welding is beneficial to manufacturers seeking to join
thermoplastic parts where both high-strength and hermetic seals are
required, or where parts have complex geometries, such as irregular
shape, or curved or internal walls. Several models of hot plate welders
are available to accommodate parts up to 72" x 24" in size. Models are
available with horizontal or vertical plates. This process is often
employed to assemble batteries, fluid reservoirs, lighters, or other
challenging plastics joining applications where cost-effective methods
and strong seals are crucial.
HH-15 Hot Plate Welder
Branson's Model HH-15 hot plate welder (at right) combines versatility
in a small footprint. The distinctive feature of this welder is its
horizontal platen, which enables it to process parts that are not
adaptable to standard vertical hot plate welders.
Features of the HH-15 hot plate welder include an interlocked door with
full guarding, which provides operator safety; an automatic cycle start
for increased production rates; a single zone temperature controller
for precise temperature control, and an optional auto part pickup
system to facilitate part loading.
Models HH24S, HH24A, HH42A, and HH72A Branson's HH-Series horizontal hot plate welders are complete assembly
systems designed to weld parts up to 24" by 72" (610 by 1829 mm), or
multiple smaller parts. (Note: the HH24S platen size is 24" by 19"/610
x 483 mm.)
Standard Features:
Touch panel human-machine interface - for quick setup and user friendly operation
Interlocked safety doors with full guarding provide maximum operator safety
Heavy duty construction for consistent alignment of tools/platen
Allen-Bradley SLC-500 - provides precise machine control with easy cycle parameter modification
Automatic cycle start for increased production rates
Independent zone temperature controllers (number based on
individual model) -- allows for uniform temperature control over entire
platen
Digital temperature controllers for precise temperature control over entire platen
Linear displacement transducer for platen and carriage position --
eliminates limit switches, improves position and speed control
Hydraulic proportional valves provide smooth, precise motion resulting in consistent parts.
Model HV-15S Hot Plate Welder Uses Servo for Greater Control
Branson's HV-15S Hot Plate Welder is a complete plastics assembly
system using a vertical heat platen, coupled with servo-driven holding
fixtures, giving the user greater control over weld results than is
possible with conventional mechanical stops.
Hot plate welding is ideal for the assembly of two or more
thermoplastic parts (up to 12" x 15," or 300 mm x 375 mm) that require
high strength and/or hermetic seals. The parts are melted with a heated
platen and pressed together to form the final assembly. The resulting
joint is clean, aesthetically pleasing, cost-effective, and free of
glue, tape, or other consumables.
