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.

Coiled Spring Pins: How To Improve Product Design and Manufacturability with the Coiled Pin [+] [--]

In any assembled component there are three ways to reduce the overall cost of the assembly: reduce the cost of the individual components, reduce component preparation cost, and reduce the cost to assemble the components.

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.

Shims: How to Control Shim Tooling Costs [+] [--]

SPIROL has several manufacturing methods that eliminate or greatly reduce your tooling expenditure.

Shim tooling costs are one of the quickest ways to drive a prototype or short-run production project over budget. SPIROL has several manufacturing methods that eliminate or greatly reduce your tooling expenditure. Whether your project is for prototype, short run or long term requirements, SPIROL has a solution to minimize your installed component costs by controlling tooling costs. Below, are some of SPIROL’s production technologies to help you determine which method is best for you.

It is often quicker and less expensive to use a shim, a thin piece of metal or composite, to level a machine tool or make components fit together, than grinding and machining to make the same mechanical adjustments. Shims act like those folded pieces of paper people place under table legs to prevent the table from wobbling. They are also used to quell vibrations and silence noisy equipment. But laminated shims are more versatile and economical than slivers of paper or machined wedges.

Laminated shims make life easier for designers and machine operators, as long as they're properly specified.

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?

Stainless Steel: Passivation: Is it Really Necessary? [+] [--]

It has been traditionally thought that passivation is the standard method of cleaning stainless steel; when in fact passivation is not a cleaning process at all. The passivation process removes any residual carbon from the surface of the part by the use of nitric or citric acid. The acid dissolves the surface imperfections, such as embedded tool steel or other free iron particles. However, the sole purpose of passivation is to remove embedded iron; not to clean the part. Passivation will not remove any oils or other non-ferrous contaminates.
