Laser plastic welding is undoubtedly an best bonding option for most healthcare gadget programs. It really is quickly, clear, and precise, but limitations in weldable plastic coloration mixtures can frequently build head aches and challenging compromises among clinical unit marketing and advertising, engineering, and production teams. This informative article will examine new choices in laser and material systems that allow for a broader range of coloration combinations, including hugely sought after but difficult-to-weld white and clear plastics.
Transmissive and absorptive qualities in laser welding
prior to moving into the specific worries and ways of welding these colour mixtures, it truly is beneficial to know how laser plastic welding works. There are two primary varieties of laser plastic welding this article will talk about:
1 μm or through-transmission laser welding
2 μm or clear laser plastic welding
The one μm vs. two μm terminology refers to the wavelength of the laser getting used and the way the various wavelengths connect with and heat up the plastics to get bonded. Figure one demonstrates how both of these kinds of welding work .
1 μm welding principle
In 1 μm or through-transmission Laser Welding, an upper transmissive layer in addition to a decrease absorbing layer are expected. The laser penetrates the upper (transmissive) layer and is particularly then absorbed into your decreased (absorbing) layer. The warmth absorbed via the reduced layer is then transferred into the upper layer by using conduction due to the fact the layers are in tight mechanical get hold of.
With the higher transmissive layer, most thermoplastics inside their normal state are entirely or fairly transmissive in the 800-1064 nm laser wavelengths, and with the decrease absorbing layer, absorptive qualities are most often achieved by including carbon black into your compounded plastic. Carbon can be an natural and organic compound and readily absorbs the laser energy-however, carbon will make the plastic visually black, which is typically not preferred by medical corporations.
