We use a custom designed and built laser welding system to permanently join materials using the radiation from a focused, energy-dense, beam of infrared light. This non-contact welding process minimizes thermal and mechanical stresses, and provides an extremely small heat affected zone, ensuring components are exposed to the least hostile welding environment possible. Our laser welding process allows us to help customers eliminate the need for gaskets, o-rings, Loctite and other hardware items while providing a higher quality product at higher production rates and lower costs. 

Ultrasonic Welding

We offer programmable ultrasonic welding for welding a variety of plastics together. Our ultrasonic welding process allows us to help customers eliminate the need for gaskets, o-rings, loctite and other hardware items while providing a higher quality product and lower costs. 

Mechanical Assembly

Manual assembly is performed by highly trained and skilled operators and can include simple assemblies with minimum hardware items or more complex assemblies requiring a greater amount of hardware items, adhesives, seals, o-rings, etc.

Quality Control

All plastic domes manufactured by Criterion Technology Inc. undergo 100% cosmetic  inspection prior to shipment to the customer. Cosmetic inspection is performed by highly skilled and trained operators.

In 2005, Criterion Technology, Inc. successfully completed
the certification audit for ISO 9001:2000. Our continued
certification and recent upgrade to ISO 9001:2008
demonstrates our commitment to superior quality standards.

On-site customer audits are welcome and encouraged.
