The most expensive engineering change is often the one discovered after the tooling is built.

That's why the best product development teams bring manufacturing expertise into the process early. By involving manufacturing engineers from the start, companies can reduce risk, control costs, improve product performance, and get to market faster.

At Redline Plastics, we help customers identify opportunities and challenges before they become costly problems.

The camera comes out and the Ninjas react accordingly: some run, some hide, and some have fully accepted their fate & pose. 📾😉We call that growth in Marketing.

Huge thank you to Pizza Garden for delivering the freshest pizzas for the BEST team today!

Redline Plastics will be closed Monday in observance of Memorial Day as we pause to remember and honor those who served and sacrificed for our country.

Have a safe, relaxing, and meaningful long weekend, Ninjas!

GROW with Redline.

Don’t settle for the same old job, the same old paycheck, the same old problems, and the same old “maybe next year” speech.

At Redline, hard work doesn’t go unnoticed. Our ninjas move up in their careers here — because we believe in giving people opportunities to learn, grow, and take that next step.

No getting stuck doing the same thing forever. No dead-end energy.
Just real work, real growth, and a team that knows how to get amped.

Yesterday, we celebrated the man, the myth, the legend - Tedd Mentink’s retirement from Redline Plastics! 🎉

After 6 years of solving problems, supporting customers, sharing his legendary sales engineering brainpower, and dropping perfectly timed one-liners, Tedd has earned a little more time for golf, cliff jumping, and breakfast carrots. We can’t wait to see what questionable adventure he decides is a great idea next.

Tedd, thank you for the impact you’ve made on our customers, our team, and the Redline culture. We’ll miss having you around full-time, but we’re grateful for every laugh, every solution, and every “classic Tedd” moment along the way.

Once a Ninja, always a Ninja. đŸ„·đŸ”„

When multiple manufacturers said no, we said let’s figure it out.

Aqua Boxing Glove needed a working prototype fast, with a national TV appearance on Shark Tank on the line. Tight timeline. Early-stage concept. No guaranteed production run.
Redline stepped in anyway.

Because at Redline Plastics, relationships come before purchase orders.
We invest before revenue.
We back entrepreneurs when it counts.
