Automation
Vibratory Feeder Noise Reduction [+]

The effects of noise can have damaging consequences and efforts should be made to minimize noise exposure.  Reduction of noise produced by vibratory feeders is one area that can significantly reduce noise exposure in the workplace.

The SPIROL Series 2000 Vibratory Feeder is quieter than conventional vibratory feeders.  Empirical data to support this claim was gathered by conducting comparison testing between a conventional square drive and a SPIROL Series 2000 drive.  Measurements and analyses were performed by Noise Control Engineering (NCE) of Billerica, Massachusetts.  The same bowl was used for testing on each drive. Noise readings were taken with an empty bowl, plastic bottle caps and metal coiled pins.  Consistent feed rates were maintained between the Series 2000 and the square drive for both the caps and the pins.

Four measurements around each vibratory feeder were taken and averaged in order to compare the square drive to the Series 2000.

Fasteners and Automation
Choosing the Proper Fastener when Automating [+]

The fastener is as important when automating as the automation equipment itself.  Choosing the right fastener may prevent exorbitant machine and fixture costs, decrease set-up and cycle times, as well as reduce the manufacturing cost of the components.

One of the biggest motivators for companies who choose automatic fastening over manual fastening is increasing productivity and reducing costs. Unfortunately, many don’t realize the impact the fastener has on achieving these goals. Not all fasteners are easy to orient, feed, or install.

Sourcing a Fastener
Lowest Installed Cost [+]

What is the real cost of a component?  When sourcing a fastener this is often taken as the one that costs less.  However, it is not that simple and it has been a question that SPIROL has answered for over 60 years and the answer is the one with the lowest installed cost.

So how do we evaluate the lowest installed cost?
