Lasers in Medical Manufacturing
Device manufacturers intent on cutting production costs not only want options, they want the process to be fast as well. Technifor’s TC 500 35-W CO2
laser is fast enough to keep
up with production of plastic-molded parts, said Boffi . Just out this year, the TC 500 is galvonometric-steered vs. gantry-based, easy to integrate, cost-competitive and extremely powerful. As a result, it offers a low cycle time and increases throughput.
The trick is to get a nice, thick oxide
layer that can stand up to passivation (a cleaning process) and autoclaving.
“We anticipate it’s going to be popular in the food and beverage industry, automotive, and for medical devices,” said key account manager Boffi .
Also innovating to increase speed is Miyachi Unitek. “To make the commonly required dark, or so-called an-
nealed mark, on stainless steel faster is a challenge, as it’s very easy to overheat the part,” said Shannon. “However, using the correct laser technology, this is possible, resulting in signifi cant throughput gains.” Shannon said his fi rm’s new LMF 3500-HP laser marker cuts this type of marking time by up to half, compared with its previous technology.
Cutting Into the Business Faster marking is not the only innovation Miyachi Unitek
has to offer. The company’s as-yet unnamed tooling option for its Sigma Tube Cutter can cut features in small-diameter nitinol tubing for neurovascular applications. Not only will the new technology cut tubing as small as 254 μm in diameter, it will immerse the part in an ultrasound bath that eliminates the need for electro-polish fi nishing.
“If you can provide a cutting process that produces minimal need for postprocessing you can shave time off the
Word on the street is our new ProfitMilling cycle drives toolpath that reduces cycle time by 75% and increases tool life by an average of 500%.
