Ultrasonic Welding

Used to bond two pieces of plastic together; produces welds that are relatively free of flash; easy to automate; particularly suitable for high volume production.

Bright Zinc Plating

Used to bond two pieces of plastic together; produces welds that are relatively free of flash; easy to automate; particularly suitable for high volume production.


The stainless steel passivation process removes "free iron" contamination left behind on the surface of the stainless steel which result in premature corrosion In addition, the passivation process facilitates the formation of a thin, transparent oxide film that protects the stainless steel from selective oxidation (corrosion).
