Welcome to Paulson’s SimTech™ Injection Molding Challenges

the plastics industry’s Exclusive Place to test your molding skill — FREE!

See if you can build an optimized process, reduce cycle time, beat our experts, all without setting off alarms. Then see how your injection molding skill ranks among your peers. Enter Paulson’s SimTech™ Monthly Challenges and find out!



Every month, three or more competitors step up to the challenge, each representing their company to battle for a spot on the Paulson SimTech™Challenge Leader Board and the chance to win the prized Paulson T-shirt at year’s end! An emblem of triumph and team bragging rights!

To play, competitors are 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!

This year, we’re shaking things up: rather than crowning an individual winner, we’re proudly declaring the championship title of “TOP MOLDING COMPANY OF THE YEAR” to the company that has earned the most points. Will you and your team mates bring the win to your company?!

PLUS! With each Challenge, be sure to see how you rank among your fellow molders, in real time, on the coveted Paulson SimTech™Challenge Leader Board.

Create a Team! Get Your Company Spotlighted

As we described above, we’ll be spotlighting winning company teams each month and then announce the TOP MOLDING COMPANY of the YEAR at the end of the year. How does this work? Start by bringing the fun to your plant. You’ll need three or more players from the same company to compete in order to win and earn a score. Be sure to have everyone register with the correct spelling of your company name to see the ranking on the leaderboard.

Get on the list now to receive each monthly challenge as they’re released and never miss a chance to win. Challenges last only one week.

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 will have a chance to earn a spot on the Paulson SimTech Leaderboard – for bragging rights of course. Additionally, each time you participate and earn a score you will accumulate points. The company team with the most points will be crowned the new SIMTECH TOP MOLDER Champion! You will need three or more players from one company to be considered a team. BIG PRIZE: the winning company will receive the coveted Paulson T-shirt for each player.
