The Challenges

There were two particular challenges that arose while making this e-cigarette case.

The first challenge concerned the profile of the case, which is generally oval in cross-section but which also reduces in diameter along its length. This makes a complex curvature that another manufacturer had tried, and failed, to make correctly. We were able to produce this shape using our HAAS 5-axis CNC mill. Our machinist carefully tailored the cutting program and selected the correct choice of cutting tool to extract the maximum performance from our advanced CNC machine, resulting in a beautifully finished profile.

The second challenge was that both halves of the case needed to come together and meet with a seamless, smooth fit. To do this, we added two magnetic, chromed steel alignment pins. These hold the two halves together firmly and in the right orientation, and help to make a leak-proof seal for the internal smoke cartridge.
