What is Solid-Bed-Break-Up?
Whether we are interested in a single screw extruder, or an injection molding machine, solid-bed-break-up is a phenomenon that is important for resin processors to understand. With all conventional screws, solid-bed-break-up is present and likely a major source of melt quality concerns.
Are You Overpacking Your Parts?
Rarely are molded parts routinely measured for weight variation from part-to-part. After all, the purpose is to fill and pack the mold. If the final molded part passes basic quality stipulations, then why dwell on the finer details? This molding philosophy is a complete disaster in countless ways, and may very well be an even larger problem than we are fully aware. Let’s explore.
Is Your Screw Tip Leaking?
The screw and valve is the heart of any injection molding operation and more than any other component can determine the overall part quality, and have a major influence on profitability. Many, if not most, injection molding firms do not fully understand non-return valve design.
