The MAY SimTech Injection Molding CHALLENGE is CLOSED! Watch for details for the JUNE Challenge coming soon!
Be sure to check out the new SimTech Champions Leaderboard introduced last year. It’s a new ranking system where consistent monthly First Place winners are listed as elite molders and new participants have a chance to achieve a top spot on the main leaderboard. If you place FIRST in any of the monthly challenges you automatically get moved to the Champions Leaderboard on your next challenge.
Open: June xx, 2023
Closes: June xx, 2023
Difficulty: High-Difficulty
Scoring: “Efficiency Scoring”
Scenario
In this month’s challenge you will be molding a Bezel out of Acrylic (PMMA) using a 300-ton molding machine equipped with a general-purpose screw. We will again be using the “Efficiency” scoring method. The part is considered to have a “above average” nominal wall section and PMMA is an amorphous material. You can find the part wall thickness within the challenge on the “Setup” tab. Wall thickness will have a great effect on the overall cycle time.
Your job is to correct any machine alarms, correct any part problems, and adjust the machine settings to get the best molding efficiency percentage. The quoted (standard) cycle time for this job is 20.0 seconds.
You will see under the Cycle Results, the “Mold Full at VPT” is 82.04%. This VPT setting is not optimized. You do have to optimize the VPT setting. The VPT should occur when the mold is between 94% – 96% full. The part has numerous quality problems. The part has Burn Marks, Size, and Voids. Notice the part is not within the part specification of 8.000” (203.2 mm) in length. The part has a “precision” dimensional specification of +/- 0.002 in (0.051 mm). Should Burn Marks or Flash occur during the process optimization exercise then those conditions should be corrected first. Burn Marks and Flash have a high probability of creating tool damage and must be addressed as a priority.
The process was quoted to run a 20.0 second cycle.
Our molding experts have achieved a cycle time below the quoted cycle of 20.0 seconds. Can you eliminate all problems, machine alarms, and mold at or better than a 20.0 second cycle? Can you beat the Paulson experts? The lowest overall cycle producing the highest efficiency score wins!
Additional Conditions
- The minimum Melt Temperature of 409°F (209.4°C) is allowed for PMMA.
- The minimum Mold Temperature allowed is 140°F (60.0°C).
- The standard (quoted) cycle time for this job is 20.0 seconds.
NOTE: In order to receive a score, all of the following conditions must be met:
- No part problems or alarms
- Part must be molded with a precision tolerance on the length. (+/- 0.002 in.)
The following “Best Practices” must be met:
- Mold Full at VPT must be 94% – 96%
- Cushion Size must be less than 10% of the Screw Back Distance
- Melt Temperature must be within ± 2°F of the Front Zone Temperature
NOTE: Clicking on the “History” button will give you valuable information on how well you are doing.
Get Started
- Log into your SimTech account at www.paulsonsimtech.com
- Click Login or Register (if 1st time in SimTech)
- Click on “Run Challenges”
- Choose “MAY Challenge 2023” and click on “Run”
- Click the “Cycle” button to begin to see the results of the present setup. Start to make controls changes, one at a time, and then click “Cycle”.
NOTE: Only make one control change at a time and then click the “Cycle” button to see the effects of that particular control change. This is the best practice to follow when making any control changes whether it be in SimTech or on an actual molding machine.
Throughout the challenges, participants will be added to the Challenge Leaderboard posted here. Plus! See if you can make it on the NEW SimTech Champions Leaderboard where consistent First Place winners compete against each other.

How does the Challenge work?
Each month, Paulson’s molding experts will devise a new molding problem for you to solve. For example, you will be challenged to mold a specific part without any defects and with the fastest cycle time. Once you’re in SimTech™, you will see the virtual control panel where you will be able to view the part, the plastic, and the machine specs in order to “mold” your part effectively. Bonus points are given, BUT if you need to access “hints,” points will be lost. Besides winning, the actual goal here is to learn.
Will I win anything?
Yes! Each month you’ll have a chance at winning a 1st, 2nd, or 3rd-place including eligibility to be crowned TOP INJECTION MOLDER! Plus, each participant can earn a spot on Paulson’s SimTech Challenge leaderboard and if you consistently place first you will be added to the Champions Leaderboard designating you an elite molder. Paulson’s SimTech Challenges are ideal for in-plant competitions too. Gather your team together for a friendly internal competition all while gaining critical thinking and key troubleshooting skills. Get Ready! Who will be this year’s SimTech Injection Molding Champion?
What is SimTech?
SimTech™ is Paulson’s most advanced, proprietary, injection molding simulation tool. It’s a powerful online engine built on decades of complex mathematical equations of plastic and process analyses that combine both molding theories and practices. All together, SimTech™ has the outstanding capability to process some 20 million calculations per simulated cycle, and check all possible simulations against possible errors. No other injection molding simulation tool is more powerful!
