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 OCTOBER Molding Challenge is now closed, see below what you missed and watch for details on the upcoming November Challenge!  

Scenario 

For the October Challenge (now closed), your task was to mold a Bracket with large ribs attached to the nominal wall out of Acrylic using a 150 ton molding machine. This part is difficult to mold. The Bracket is susceptible to voids and sinks and dimensional issues. This part must be molded with a tight tolerance on the length. The part is 10.000 inches long with a tolerance of =/- 0.002 in.

The initial setup for this challenge was done by a person who is not a molding expert. Your job is to correct any machine alarms, correct any part problems, and adjust the machine settings to get the best molding efficiency percentage. This is called process optimization. The quoted (standard) cycle time for this job is 42 seconds.

You will see under the Cycle Results, the “Mold Full at VPT” is 90.73%. This VPT setting is not optimized. You’ll have to correct this.  The VPT should occur when the mold is between 94% – 96% full. The part has some problems. The part has flash, voids, undersized. Notice that the part does not meet the nominal dimension of 10.000 in.

Flashing is a critical part problem and must be addressed first in the optimization process. This is done because this type of part problem creates a high probability of tool damage. Once the flashing is corrected then proceed to optimize the cycle time and part dimensions.

Our molding experts have achieved an efficiency of 119%. Can you eliminate all problems and mold better than a 42 second cycle…and beat the expert’s efficiency score?

Additional Conditions

  • The minimum Melt Temperature of 409°F is allowed for Acrylic.
  • The minimum Mold Temperature allowed is 140°F.
  • The standard (quoted) cycle time for this job is 42 seconds.

In this set-up, try to optimize the process following molding best practices. Those are:

  1. Mold Full at VPT must be 94% – 96%
  2. Cushion Size must be less than 5%-10% of the Screw Back Distance
  3. 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.

Get Started

  1. Log into your SimTech account at www.paulsonsimtech.com
  2. Click Login or Register (if 1st time in SimTech)
  3. Click on “Run Challenges”
  4. Choose “OCTOBER Challenge 2021” and click on “Run”
  5. 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 including eligibility to be crowned TOP INJECTION MOLDER! Plus, each participant can earn a spot on Paulson’s SimTech 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!
