Ultrasonic Welding

Spin Welder

Ultrasonic Welding is the most frequently used process for welding plastic. The welding process converts electrical energy to mechanical energy (ultrasonic vibrations), generating enough friction between two plastic parts to create heat. With the application of force, the heat causes the two thermoplastic parts to form robust molecular bonds. Ultrasonic welding is a fast, clean, and efficient method for welding plastic. It consumes very little energy and does not involve the use of solvents, adhesives, or fasteners. There are two types of ultrasonic welding that are commonly used:

Pneumatic-Controlled Ultrasonic Welding

Traditional welding method that is relatively inexpensive but does not allow for the high level of control that may be required by high standards of quality assurance.

Servo-Controlled Ultrasonic Welding

Welding method that enables a greater level of control and quality assurance than the pneumatic-control method.  Initially used in the medical device assembly arena, it is now being used throughout all industries due to its higher Cpk values and more reliable welding characteristics.

Laser Welding

Laser welding uses a laser beam to melt the plastic in the joint area by delivering a controlled amount of energy to a precise location. This process has been improved for manufacturing of medical devices, electronics, and some consumer goods when a "clear-to-clear" or a "clear-to-colored" assembly is required.

Vibration and spin Welding

Vibration and Spin Welding, much like ultrasonic welding, utilizes mechanical friction and force to generate adequate heat to fuse two materials together. This method is fast, clean and can be used to join two dissimilar materials.

Hot Plate Welding

Hot Plate Welding is the process of using a heated platen to melt the surface of two thermoplastic parts. Once an acceptable level of melting has occurred on the surface of each plastic piece, the platen is removed and the two pieces are pressed together to form a weld. Hot plate welding provides a high level of melt temperature control and superior weld strength. This method is ideal for joining large and intricate parts.


Precision Ultrasonic Cutting Technology

Ultrasonic Cutting

This process converts electrical energy in to mechanical energy with vibrations of 20, 30 or 40 kHz. Ultrasonic cutting is a preferred technology for cutting a variety of fibers, food products, and a number of other pressure sensitive products.
