JUNE CHALLENGE INSTRUCTIONS 

SCENARIO: June Molding Challenge – Hard Parts Per 120 Job Scoring

For our JUNE challenge we are changing the scoring method. In our first two challenges we used the Efficiency Scoring Method which is based on finding the most efficient cycle time. In this challenge, you will be scored on the number of good parts made.
(Open from 6-12-2019 to 6-20-2019This challenge will really test the best molders!

SCORING
The job is scheduled for 120 hours.  This includes set-up time and production time. Your score will be the number of good parts made.

More precisely, the score calculation is the number of parts made so far (by clicking the Cycle button), plus the projected number of parts to be made in the remaining time.  The projected number is based on the most recent cycle time, as long as there is currently a “good part” and you have met “optimal machine settings” noted below.

Each click of the Cycle button consumes some time, equal to the current Cycle Time, out of your 120 hour budget.  If you adjust your barrel temperatures, this consumes extra time proportional to the amount of change.  Additionally, there are time penalties for taking hints.  All of these effects eat into your time budget and therefore reduce your potential score.

As in the previous challenges, you must not have any alarms or problems to have a “good part”.  New for this scoring method, we require “optimum machine settings”. Your Machine Control Settings and Cycle Results must meet the following requirements.

  1. Cushion Size must be less than 10% of the Screw Back Distance.
  2. Mold Full at VPT must be between 94% and 96%.
  3. Melt Temperature must be within ± 2°F of the Front Zone Temperature.

Any parts molded that are not “defect free” or do not meet the “optimum machine settings” above, DO NOT count as good parts made, and furthermore will cause projected number of parts to drop to zero.  Your score will show a very low number (equal to the number of good parts made so far, if any) while these conditions persist, but will rebound as soon as you clear the bad conditions.

SCENARIO
The set-up in this challenge is already making parts without any defects but the machine settings will cause a variety of erratic part problems down the road. Your job is to improve the machine control settings and reduce cycle time.

It is your choice whether to make cycle time reductions first or complete the machine setting requirements first.  Watch the production count (score) in the upper right-hand corner of the screen to monitor the production count. Remember, any parts made outside of optimal machine settings – conditions 1, 2 and, 3 above – are not counted and your score will be very low or 0.00 during this time.

If you have achieved “good part” and “optimum machine settings” and are accumulating parts (score), you can continue to adjust machine control settings to reduce the Cycle Time and therefore improve your score.  This may cause you to return to bad conditions (low score) occasionally.  Always remember to return to good settings before leaving your session so you do not accidentally drop off the leaderboard!  You can return to your session at any time to try new settings, but be mindful of the challenge cutoff.  At that instant, your existing score will be captured for the final leaderboard.

Part dimensions– The normal length for this part is 6.5 inches ± 0.005”

Cycle time –The quoted cycle time for this job is 15 seconds.

Expected Production: 57,600 parts

NOTE: if you get a Fill Time of 000 it means the mold is full but not packed. Make the necessary machine control adjustment.

GET STARTED

  1. Log into your Simtech account by clicking this link.
  2. Click Login or Register (if 1st time in Simtech)
  3. Click on “Run Challenges”
  4. Choose “JUNE Challenge 2019” and click on “Run”
  5. Click the “Cycle” button to begin. Start to make controls changes, one at a time, and then click “Cycle”.

NOTE: You can make more than one machine control at a time. But to avoid confusion, it’s best to change only one machine control at a time. The exceptions are barrel temperatures and fill rates.

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 have the ability to earn points. At the end of six months, the person with the most points earned will be eligible to win the Grand Prize of $3,000 worth of online training from Paulson.

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!

How do I enter?

In order to participate in the monthly challenges, you MUST register by filling out the form. You will then receive email alerts when each challenge is released. Act now and be ready to take the challenge.

May the Best Molder Win!
