Lower Prices Expected
Some of softness is the result of pressure from sagging virgin prices. The economic outlook is a factor too.
Energy Miser: Reducing Compressed-Air Usage
Many manufacturing sites operate on the assumption that compressed air is free. Usage is totally uncontrolled, and open air lines cost real money.
Look Before You Leap: When Direct Extrusion Makes Sense
The process offers great opportunities to extrude a better product at less cost, but it’s not for everyone. The formulation, product mix, and anticipated volumes must be carefully assessed to determine whether DE is the preferred manufacturing methodology.
Mold Filling Simulation: What, When, Why, How
Mold-filling analysis is the right direction to go, but if you want to arrive at your destination—good parts and an efficient process—you’ll need to pay attention to all the details and select an experienced professional to do the analysis.
