Jet Dispensing System from Asymtek
Jet dispensing system.
Carlsbad, CA — Asymtek, a Nordson company, has released the DispenseJet DJ-100 family of piezo-electric jets. According to the company, the new, non-contact jet dispensing system combines high production speed with high accuracy and process control. The new system is suitable for a wide range of fluid types and viscosities.

There are three models available — each designed to dispense different types of fluid: the DJ-100 Standard, the DJ-100 NC for low viscosity materials, and the DJ-100 GH, designed for highly viscous fluids.

Jetting offers many benefits over traditional needle dispensing to deliver speed, quality, flexibility and low cost of ownership. With the patented "Jet on the Fly" technology, the jet flies over the part or substrate and shoots precise volumes of fluids in dots, lines, and patterns. By using piezo-electric technology to jet fluid onto the substrate, the DJ-100 eliminates the need for time-consuming Z-axis movement. High flow rates of up to 200 mg/second and high shot rates of up to 150 dots per second can be achieved. Fluid can be dispensed into areas that are difficult to access and onto uneven or other substrates where a dispense needle cannot contact the substrate.

Designed for ease of use, the jet system comes with a serialized hardware set that includes a matched ball and seat, which eliminates the need for hardware adjustment and replacements that are subject to operator error. The company's patented Calibrated Process Jetting (CpJ) feature ensures quality by utilizing weigh scale feedback to maintain consistent dispense volume. Dot diameters as small as 200µm (0.008-in.) can be achieved.

Because there are fewer consumable parts and the components are designed for long life, the system offers a low cost of ownership. Its slim design maximizes the dispensing envelope, further enhancing productivity. The company's patented "Dot on Dot" technology offers flexibility by jetting multiple dots in the same location to create larger dots.
