JULY 2022 SimTech™ Challenge Wrap Up
Two months in a row now Draexlmaier Automotive of America has clinched the First Place spots in both the company category and individual category. They are swiftly becoming the team to beat. However, Team PlastiKon is close behind. Will they outpace Draexlmaier?
Challenge Specifics & Notes from our Experts
This month’s challenge had a bit of a twist. We designed and configured a general purpose screw for the 150-ton molding machine in SimTech. Some of you may have noticed this machine and screw configuration has been used in prior challenges. The material used for the July Challenge is High Density Polyethylene (HDPE), a semi-crystalline material.
Molding a Cell phone Cover was this month’s part to produce. This type of part is considered an average nominal wall type part. The quoted (standard) cycle time for this job is 8.0 seconds. Which is quite a bit faster than the quoted cycle for the previous challenge part (14.0 cycle). So, for this month we had to mold a faster cycle with a semi-crystalline material.
In our expansive course offerings, we teach the specifics of a general purpose screw design (“GP” screw), a screw designed for shear sensitive materials (like PVC, polycarbonate, most “ring-structured” polymers) and a semi-crystalline screw design. We also teach the specifics for the semi-crystalline screw which is designed with a higher compression ratio and longer feed section on the screw.
The winning setup uses a good temperature profile on the heating barrel. With the amorphous screw, the winning setup uses a “reverse profile” temperature setting. This means the material temperature is set with the rear zone higher than the front zone and nozzle temperatures on the barrel of the machine. This will provide the extra energy needed to melt the semi-crystalline material using a GP screw and will aid in providing uniform mixing and melting of the polymer.
This month, we chose to feature the set-up from our second place finisher, Austin Haycraft from Plastikon. Austin focused on using the lower processing temperature range for the HDPE. He utilized a unique injection fill rate profile that utilized a slower fill rate into a faster fill rate and then slow the fill rate down for the last 20% of the fill to prevent any fill related defects. By optimizing the melt temperature, fill rate profile and mold temperature he was able to run a cycle faster than the quoted cycle and ultimately ran a cycle faster than our experts!
If you don’t have a full understanding of this configuration, Paulson Training Programs can help you with this. We offer a thorough explanation in our Basic and Advanced courses and seminars. Hope to see you there!

Having Fun with our Competitions?
Imagine the team of skilled molders you could create if SimTech was in your plant 24-7? Your employees could be improving their molding expertise in a safe, low-cost environment, building critical thinking and troubleshooting skills. And you can stage your own friendly in-house competitions. It’s proven, molding simulation is the best and most cost-effective way to become a better molder. You don’t want your employees making their mistakes or trying new techniques on the production floor at an actual machine—now that’s a costly way to learn. The simulation of complex processes is quickly becoming the gold standard of skill development. SimTech is the answer for injection molding.
Here’s just a few of the applications you can employ with SimTech:
Hiring Qualified Employees – Before hiring a potential employee, test their knowledge and skills with problem solving exercises in Simtech.
Technician Promotion – Give your candidates for promotion a test before you make that decision.
In-plant Competitions to promote learning and discussion – Have your own competitions amongst your team. Have a discussion on what process settings work and why.
