Engineering is producing small-diameter
microtubes and profiles made ofKetaSpire
polyetheretherketone (PEEK) resin from Solvay Advanced Polymers LLC for the medical industry. Microtubes
made of KetaSpire PEEK offer greater strength and rigidity than PTFE microtubes
and are easier to work with than those made of stainless steel. They are used
in a range of medical applications including catheters, endoscopic working
channels and laparoscopic instruments. IPE
has produced microtubes made of unfilled KetaSpire KT-820 NT PEEK in sizes of
0.029 OD by 0.016 inch ID (0.74 OD by 0.41mm ID) and 0.077 OD by 0.057 inch ID
(1.96 OD by 1.45 mm ID). The company can make PEEK tubes with up to a 0.25 inch
(6.35 mm) diameter. IPE manufactures
the microtubes on a 1 inch extruder specially designed for high-temperature
materials like PEEK, which process at very high melt temperatures in the range
of 370C (700F). IPE also has the capacity to manufacture PEEK profiles, both
open and hollow, for a wide range of applications.
KetaSpire PEEK is a chemically
resistant plastic and offers strength, fatigue resistance and a continuous-use
temperature of 240C (464F). It can withstand more than 1,000 cycles of steam
sterilization without any significant loss of properties and is also compatible
with other sterilization methods, including ethylene oxide, vaporized hydrogen
peroxide and gamma radiation. Based on biocompatibility testing as defined by
ISO 10993-1, KetaSpire PEEK demonstrates no evidence of cytotoxicity,
sensitization, intracutaneous reactivity or systemic toxicity.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
