Craig Machinery & Design, Inc.

United States

Our professional team can assist you from the initial stages of part design to the final production run to ensure your vibration welding projects are a complete success. Joint design, part wall thickness and material types are as critical as the fixturing to insure a good repeatable weld. Vibration weld tooling from simple pockets to tooling with multi-clamp systems, part defect sensors and vacuum part holding can be designed and produced at Craig Machinery. We have our own vibration welders to help in prototype welding and short production runs.

Since 1977, Craig Machinery & Design Inc. has designed and built automation machinery for the plastics industry. Craig Machinery & Design is an authorized Integrator for Fanuc America. We have experience with using robot cells for material handling, assembly and dispensing. Craig Machinery also has programmed ABB, Denso, IAI and Yamaha 6-axis and SCARA robots.

Craig Machinery can build your Manual or Semi-Manual assembly stations with part sensors, bin pick sensing, screw driver feedback and vision systems to assure all components of an assembly are present. Machine reset reject chutes, programmed touch screens with assembly maps and pick lights are used to assist the operator in making a perfect part every time.

If a hermetic seal from welding is a must, Craig Machinery can leak test your part either online or offline from the welding system. Whether 100% leak testing or lot sampling, Craig Machinery can accommodate your leak test requirements with pressure decay or mass flow leak test systems.

Craig Machinery & Design are experts when it comes to Ultrasonic welding of plastics. We can recommend joint designs then automate the process to meet your needs. Our professional team builds systems for staking, spot welding, swaging or conventional ultrasonic welding. Machine systems include: Custom Sound BoxesSequencing one power supply to multiple convertersMounting Ultrasonic Welding stacks to RobotsMulti-head systemsContinuous Sonics SystemsDial Indexer Welding machine with added processesCustom Ultrasonic ActuatorsCraig Machinery also has a variety of frequency lab machines for proto-typing or small product runs.

Clamshell blister packaging has become popular for high visibility of the product, but making the clamshell tamper-resistant is a must. Ultrasonic welding requires no adhesives, heatshrink bands or staples and the final package will have a nice appearance and high strength. Craig Machinery & Design, Inc. pioneered continuous welding for produce and baking industry packaging machines. This application includes high speed lettuce tub lid welders with speeds of up to 100 fpm. We can also build machines for plunge welding clamshell packages for a variety of sizes and cycle times. Craig Machinery can build machinery for almost any need, from simple load under the horn table systems with two palm buttons to multi-welder rotary indexing machines with an auto eject system and an operator interface touch screen.

We are not just plastic assembly. Craig Machinery can handle a variety of assembly automation projects from retrofitting existing equipment to new equipment.
