165 and 220 ton ArburgsElite Plastics continues its stride towards improvement.  At our Oregon facility we have recently added 4 new Arburg injection molding presses over the last year.  The 2 pictured are the latest.  These additions support our heavy medical validation process for repeatability and reliability that we have established.165 and 220 ton Arburgs

Image previewThis entry is primarily based on the IQ (installation qualification) portion of any process validation. 

One area that we have found to be most important on any process is the validation of the installation of any given process.  All equipment used to manufacture a product needs to be validated and most importantly should have its own procedure and documentation identifying how the equipment should be set-up every time the product is run.  A quick example of this is the hose length of a simple mold heater.  This hose length is an example of how a process can change simply by adding 1 extra foot of hose length to a heater.  All peripheral equipment should always be accounted for when creating a repeatable process.

Laser etched touch panel Laser etching is a great approach to marking a variety of materials that would otherwise be difficult, if not impossible, to mark mechanically. Laser etching is ideal for near finished products needing identification, barcode, serializing, text or image backlighting or intricate decorative work.

The picture provides a perfect example of the use of laser etching.  The symbols were laser etched onto the buttons after the rest of the component was completed.

For those that are not in the industry, hot stamping seems like a strange process.  Why not use a wet ink?  The answer is that the hot stamping is clean, dry, fast and free from the manufacturing limitations commonly associated with wet ink printing.

Hot stamping is a unique process that transfers color pigment or metallic material from a continuous film carrier sheet to a component. The heat and pressure of hot stamping permanently transfers the image to the plastic or metal surface. A silicone rubber die conforms to fit the slightly uneven surfaces often found in molded parts, and allows for excellent resolution and repeatability. 

In the photo, the silver on the NEC is transferred using hot stamping, demonstrating how well the process works on raised surfaces.
