INSTRUCTION MANUAL • MODELS 1099/1096

INTRODUCTION

The models 1096 and 1099 are 20 kHz precision pneumatic actuators used

for ultrasonic plastics assembly. The 1099 is a tabletop version, and the 1096

can be mounted on a bridge or rigid structural member for use with automated

systems. These presses can be supplied with the following power supplies:

■ FD . . . . . . . . . . . . .Timer

■ FDL . . . . . . . . . . . . .Timer/Linear Encoder

■ FM . . . . . . . . . . . . .Microsonic Processor™

■ FO/ML . . . . . . . . . . .Microsonic Processor™/Linear Encoder

OVERVIEW OF ULTRASONIC PLASTICS

ASSEMBLY

WHAT IS ULTRASONICS?

Ultrasonics refers to vibrational waves with a frequency above the human

audible range which is usually above 18,000 cycles per second (Hz).

PRINCIPLE OF ULTRASONIC ASSEMBLY

The basic principle of ultrasonic assembly involves conversion of high

frequency electrical energy to high frequency mechanical energy in the form

of reciprocating vertical motion which, when applied to a thermoplastic,

generates frictional heat at the plastic/plastic or plastic/metal interface. In

ultrasonic welding, this frictional heat melts the plastic, allowing the two

surfaces to fuse together; in ultrasonic staking or insertion, the controlled flow

of molten plastic is used to capture or lock another material in place (staking)

or encapsulate a metal insert (insertion).

ULTRASONIC ASSEMBLY SYSTEMS

“Sonics” ultrasonic assembly systems are generally composed of the

following major elements: a power supply, converter, booster, horn, pneumatic

press and holding fixture, as detailed in the diagram on the next page. A

review of this diagram will help you understand the basic elements involved in

the assembly process and their relation to each other.
