A tip is a economical
replaceable part commonly known as an interchangeable device that is
tightened onto another component such as a tapped horn, heated probe or
heated tip block. Tips for ultrasonic horns are generally made from
titanium and typically designed to perform a specific function such as:
staking or spot welding. Knurled, flat and overweight tips are also
available. Tips for heat based applications are made from highly
conductive, yet durable materials and are also designed to perform
specific functions such as: staking, swaging, insertion, sealing,
date-coding and hot knife de-gating.
Thermal Tooling
Tooling for
Staking, Swaging, Insertion, Sealing, Date Coding and Hot knife
De-gating is commonly mounted to the upper portion of a press and heat
is provided by probe or platen assemblies. Coil wound or cartridge
heaters, with thermocouples, supply maintained heat to the tooling.
Tips are commonly mounted to a probe or platen and are precision
machined to produce the desired operation on your application. PAS
utilizes the latest in technologies and finest materials to produce the
highest quality products available. PAS manufactures tooling and
supplies replacement components for all makes and models of machines.
If you have a custom-built machine, call with your mounting dimensions.
Ultrasonic Horns
A horn is an acoustic tool, usually titanium, aluminum
or hardened steel, that transfers vibratory energy from the ultrasonic
welder directly to the parts being assembled. PAS manufactures quality
horns in 15 kHz, 20 kHz, 30 kHz and 40 kHz, all precision machined from
high-grade alloys. PAS provides a complete line of standard horns
including: Half & Full Wave, Exponential & Catenoidal, Bar,
Block, Rectangular, Round (High-Gain, Solid, Hollow and Slotted) as
well as custom horns: Knurled and Serrated Faced, Vacuum, Nodal
Plunger, Contoured and Composite. (Click to enlarge) (Click to enlarge)
Converters
A converter receives high-frequency electrical energy from
the power supply and converts it into mechanical vibratory energy at
ultrasonic frequencies. PAS provides new and pre-owned converters and
also repairs damaged converters of almost every make and model
available. Frequencies include 15 kHz, 20 kHz, 30 kHz and 40 kHz.
Boosters A booster can either increase or decrease the amount of
amplitude at the face of a horn. PAS provides booster horns in several
different magnification ratios and are available in aluminum or
titanium, new or pre-owned. Frequencies include 15 kHz, 20 kHz, 30 kHz
and 40 kHz. Fixtures A fixture supports and aligns the part to be
assembled. Generally, it is fabricated from aluminum or steel and
sometimes is lined with poured cast urethane/epoxy or other resilient
materials. PAS manufactures fixtures from simple machined shapes to
complex CNC contour milled shapes. Additional pneumatic or manual part
clamping/ejection and vacuum/expansion mechanisms can be integrated
into the lower tooling. (Click to enlarge) Vibration Welding Tooling
for vibration welding includes an upper ’Äútuned’Äù drive head and
lower fixture. Strong, lightweight tooling is key for this process. PAS
provides custom engineered rugged components to ensure quality welds.
Precision machining is critical to ensure your part is properly located
and supported. Call us for quotes on all makes and models.
Spin Welding
Tooling for spin welding typically includes upper tooling or a
’Äúchuck’Äù with keyed features to drive one half of the assembly
against a fixtured or secured mating part.PAS provides custom drive
heads and fixtures for simple designed parts, to complex parts
requiring vacuum and expandable features to lock and drive your part.
Call us for quotes on all makes and models.
Hotplate Welding
Tooling
for hotplate welding is commonly designed to lock in both parts to be
assembled. Applications where near contact heating is a must, demands
precision holding and support. PAS provides custom tooling for simple
designed parts, to complex parts requiring pneumatic clamping and
moveable supports to lock and locate your part. Call us for quotes on
all makes and models. Coatings and Plating Increase the life of your
tooling with the addition of platings or coatings. Several different
options are available including: chrome plating, Teflon hard coating,
anodizing, black oxide, carbide, chemical films, copper, nickel and
more.
Optional Accessories
Several accessories are available to
increase productivity and achieve higher part quality. PAS offers the
following available options: film feeders and film, slide tables,
hydraulic dampers, leveling bases, amplitude gauges, sound enclosures,
machine stands, converter vises, torque wrenches, horn studs, step
studs and Mylar washers.
