Polymer (Mylar) Washers for Stack Joints (35 pack)

$26.50

These washers made of heat-resistant Mylar(TM) can be used instead of high pressure silicone grease in ultrasonic stack joints.

IMPORTANT: Use a new washer each time the tooling is reassembled. Do not use both grease and a washer in the same joint.

Washers come 35 to a pack. Order the number of packs you want, not the number of washers.

Description

These washers made of heat-resistant Mylar(TM) can be used instead of high pressure silicone grease in ultrasonic stack joints.

High pressure silicone grease probably does the best job of “wetting” the surfaces for good coupling and low acoustic losses, but it is much harder to train somebody to apply the grease correctly than it is to use a fresh washer each time the tooling is assembled. Also, silicone can interfere with decorating operations such as printing or painting, and is therefore banned from some plants.

To select the correct washer, measure the stud diameter and use the next larger ID, then measure the diameter (or diagonal) of the faces in contact, and use the next larger OD. If your OD is larger than the 46 mm, use 46 mm OD.

Sizes:

ID 8 mm, OD 25 mm (40kHz, 1 in OD)

ID 9.7 mm, OD 38 mm (3/8 in ID, 1.5 in OD)

ID 13 mm, OD 38 mm (1/2 in ID, 1.5 in OD)

ID 13 mm, OD 46 mm (1/2 in ID, 2.0 in OD)

IMPORTANT: Use a new washer each time the tooling is reassembled. Do not use both grease and a washer in the same joint.

Washers come 35 to a pack. Order the number of packs you want, not the number of washers.

20TV900
20KHz Stack Vise for Ultrasonic Tooling
This stainless steel stack vise is designed specifically to clamp 20KHz converter front slugs and booster spanner "collars" during assembly or disassembly to reduce damage to expensive ultrasonic stack components. The vise features two clamping chambers, one for tooling 1.5" (25.4 mm) dia. and one for tooling 1.8" (45.7 mm) dia. The two-pin hinge design allows the upper jaw to "float" and seek the best clamp position on the tool for maximum contact. The securing bolt has a long lever handle that can be re-positioned out of the way once secured. The securing bolt can be completely removed so the upper vise jaw can be fully opened. The steel spanner-hole pins are set in stepped holes such that they can be driven out from the bottom of the vise should they ever need replacement.

High Pressure Silicone Ultrasonic Stack Grease
The function of grease in the joint is to: 1. Fill the microscopic valleys in the surface of the tooling to improve acoustic transfer from one component to the next. 2. Remain in the joint so the metal of the two pieces of tooling do not become "clad" together by the action of the ultrasound and thus impossible to disassemble. Never use grease and a polymer washer in the same joint.
