File Compressor Conversion

Return to Solutions

The Challenge

For many applications, plastic offers several of the advantages of steel with none of the disadvantages. One company asked us to look at the viability of converting their file compressor, which helps to minimize the space files take up in a file drawer, from steel to plastic.

Our Solution

Royal Technologies designed a prototype, injection-molded ABS plastic file compressor. In addition to meeting every performance requirement, our proposed compressor weighs less than 30% of its steel counterpart at roughly 70% of the cost.
