NPE2018 New Technology Focus: Healthy Interest in Medical
Medical molding is a big presence at NPE.
Medical devices and disposables remain an especially attractive market for plastics—and plastics machinery. Several injection press makers will address this market with molding demos.
Engel, for example, will repeat an impressive feat from K 2016 by molding eight interdental brushes, each with up to 500 tiny bristles, and a total shot weight of only 1.93 g. (Booth W3303)
KraussMaffei will mold LSR medical parts. (Booth W403)
Netstal will run pipette tips in 128 cavities at a cycle time of 5.6 sec. (Booth S16088)
Sumitomo (SHI) Demag will mold eight thin-wall medical dosing cups in 3 sec. (Booth W3045)
Wittmann Battenfeld will mold PP pipettes in eight cavities on an EcoPower all-electric “cleanroom machine.” (Booth W3742)
Absolute Haitian will run an in-dwelling needle body of cellulose acetate propionate in eight cavities. (Booth W143)
Arburg (W1325) is micromolding a dual-durometer LSR/LSR membrane for valves used in medical and automotive applications.
First find out if they are the result of trapped gas or a vacuum void. Then follow these steps to get rid of them.
One of the more prominent trends in processing is the need for higher plastic pressures to mold parts.
Most molders work with two parameters for establishing second-stage pressure. But within Scientific Molding there are actually four.
