Decompression—aka suckback—is a very important setting on an injection molding machine. On today’s machines, molders typically get the option to set decompression before and after screw rotation/recovery. Are they using this feature to their advantage?
Focus on six key metrics to help you determine when a process is lined out and stable enough to start production.
Gravimetric blenders provide for the most consistent and accurate blends of plastic materials and additives, but even these seemingly simple machines need some TLC after a long production run.
Gravimetric blenders offer plastics processors considerable savings.
With intelligent and adaptive control technology combined with precision hardware, today’s best gravimetric blenders can deliver previously unachievable levels of accuracy. You’ll see the difference in more consistent injection molded or extruded product and reduced colorant and additive waste.
Despite their integral role in transforming pellets fed through the hopper into parts ejected from the mold, visibility into the performance, health and efficiency of screws is difficult to discern for many reasons, not the least of which being the fact they’re located inside a barrel.
Smaller parts, a wider range of resins and reinforcements,and retrofittable molding equipment were among the news indirect-compounded long-fiber thermoplastics presented at a recent Plastics Technology conference. Extrusion and thermoforming are also new extensions of this process.
In addition to introducing its new SmartPlus line of servo-hydraulic injection molding machines, Wittmann Battenfeld will feature multiple machines at its booth and stream video of other cells from its labs.
The best approach is to implement and standardize a three-step program to ensure you are purging in the best and most cost-effective manner possible.
