Coax FactsContinuous improvement and statistical process control are useful,time-tested techniques—they have been used since the 1950s—buttheir use must be tailored to specific applications. For example, atypical manufacturing metric is parts per minute, but many rollformers should measure feet per minute. This and other tips can helproll formers accurately evaluate their productivity and measure theimpact of process improvements.

The ins and outs of extrusion bendingExtrusions can be tricky to bend and handle. Paying close attention tobender selection, die design, programming, and material handling can help to ensure efficient and productive bending.

Serpentine bending in productionBending serpentine profiles—successive 180-degree bends, which typically are used in refrigeration systems—can be a challenge. By their nature, they tend to cause interference among the various bend dies, and they can be difficult to handle. Good planning in selecting a bender, planning the process, and paying close attention to infeed and outfeed options, can help make a serpentine project successful.

From the CAD station to the production floorConventional tube bending data, regardless of format, is entered manually and therefore susceptible to errors. A modern approach involves using a CAD system to generate a STEP file, which the CAD program exports directly to the bending machine. This method is fast and eliminates errors. The drawback is that such a system requires additional database management efforts.
