The 2021 SIMTECH™ INJECTION MOLDING CHALLENGES ARE IN FULL SWING!
Will YOU be the next SimTech ProMolder Champion? Can You unseat our reigning champ, of two years in a row, Mr. Johnny Ash?
Welcome to Paulson Training Programs’ SimTech™ Injection Molding Challenge, part of a series of monthly challenges testing your injection molding abilities using the world’s most advanced injection molding simulator – SimTech™.
Each month you will be tasked with molding a defect-free part, within specifications, with the fastest cycle time using Paulson’s online virtual injection molding machine, SimTech™. It’s FREE! Plus, each time you participate you accumulate points and if you score you earn a spot on the Paulson SimTech Challenge leaderboard; for bragging rights of course. At the end of the year, only ONE PERSON will have earned enough points to take the championship title of SimTech ProMolder and win the coveted Paulson ProMolder T-Shirt! But wait! There’s More! Each time you participate you become eligible for the end of the year drawing for a chance to win TWO FREE seats for one month’s subscription to a Paulson University online course. That’s two months of FREE training!
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 ProMolder Champ?
THE APRIL 2021 Challenge is OPEN.
Closes: 4/22/21 at 5pm (EST)
Difficulty: HIGH Difficulty
Scoring: “Efficiency Scoring”
APRIL Molding Challenge Details
In this month’s challenge you will be molding a Bezel out of Polypropylene using a 300 ton molding machine with a Semi-crystalline screw configuration. We will be using the “Efficiency Scoring Model” method.
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 22 seconds.
You will see under the Cycle Results, the “Mold Full at VPT” is creating an machine alarm issue. This VPT setting is not optimized. You’ll have to optimize the VPT setting. The VPT should occur when the mold is between 94% – 96% full. The part has some problems. The part is oversized, warped, has burn marks and Flash. Notice the part is not within the part specification of 8.000” ± 0.002”. The part has a standard dimensional specification of +/- 0.002 in.
Our molding experts have achieved an efficiency of 106%. Can you eliminate all problems and mold better than a 22 second cycle…and beat the expert’s efficiency score?
- The minimum Melt Temperature of 389°F is allowed for
- The minimum Mold Temperature allowed is 70°F.
- The standard (quoted) cycle time for this job is 22 seconds.
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 standard tolerance on the length. (+/- 0.002 in.)
“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 Nozzle and Front Zone Temperature
Good to Know: Clicking on the “History” button will give you valuable information on how you are doing.
- Log into your SimTech account at www.paulsonsimtech.com
- Click Login or Register (if 1st time in SimTech)
- Click on “Run Challenges”
- Choose “APRIL Challenge 2021” 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.

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 prize including eligibility to win $500 worth of training credits to put toward an online Paulson course or seminar. But wait! There’s More! At the end of the year, only ONE PERSON and their company will be chosen among all the previous monthly FIRST PLACE winners for the GRAND PRIZE of $6,000 worth of training from Paulson. Plus, each participant can earn a spot on Paulson’s Challenge leaderboard. 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!
