Plastic Welding Equipment & Intelligent Assembly Solutions
Designs, manufactures and supplies advanced technology plastic welding solutions used in manufacturing operations throughout the major industrial regions of the world. In addition they develop and apply their high power ultrasonic technology to other industrial applications such as cutting tacky and abrasive materials, welding of metal components, sieving, and fluid processing.
Ultrasonic Plastic Welders
This process works through the translation of AC current into mechanical vibrations using piezo-electric ceramics. The vibrations are then passed through the part to the joint at which point they cause stress and strain in the contact area between the two parts which leads to localized heating and melting of the polymer. Ultrasonic welding typically has weld times from one-tenth to two seconds and Dukane's ultrasonic welding equipment can handle parts from approximately one-eighth inch diameter at high frequencies up to twelve inches square at low frequencies.
This process works through either linear or orbital motion of one part relative to the other. This results in surface friction that leads to heat generation and the formation of a melt layer at the joint. Vibration welding typically has weld times from one to five seconds and Dukane's vibration welders can handle parts from approximately two inch diameter up to five feet long.
This process works through rotational motion of one part relative to the other. This results in surface friction that leads to heat generation and the formation of a melt layer at the joint. Spin welding typically has weld times from one-half to five seconds and Dukane's spin welding equipment can handle parts from approximately one-half inch diameter using high speed motors up to nine inches diameter using high torque motors.
Hot Plate Welders
In this process, the facing surfaces of the two parts are heated through conduction, convection and/or radiation from an actual heated platen. The two parts are either pressed against the hot plate, or held next to it for some period of time, then the hot plate is removed and the parts are pressed together to form the weld. Hot welding typically has weld times from ten to twenty seconds and Dukane's hot plate welding equipment can handle parts from approximately one inch diameter up to five feet long.
Heat Staking Thermal Press Welders
Thermal staking provides an alternative to ultrasonic welding when there are limitations or requirements that ultrasonic technology cannot produce.Thermal Staking also provides an alternative to ultrasonic welding when the two parts to be bonded are of dissimilar materials which will not bond together or if a simple mechanical retention of a part relative to a second part is adequate.Common type of heat staking applications involves the attachment of plastic to metal, plastic to plastic or multiple staking bosses to be simultaneously staked at various heights or sizes.
From simple to complex, Dukane can design and build an assembly system for your application(s). Many of the systems we build feature servomotors, optical part sensors, indexing tables and sound enclosures.
