About XactMould
Hi, I'm Mike Krijnen. I'm the founder and engineer behind XactMould. For more than 25 years, I've been helping toolmakers and manufacturers develop practical, reliable, and manufacturable injection mold designs for projects of every size and complexity.
After graduating as a Mechanical Engineering engineer, I started my career as a mold designer at a toolmaking company specializing in multi-component injection molds. There, I gained a solid foundation in mold construction, manufacturing, and the practical aspects of turning complex concepts into reliable production tools.
Today, I have more than 25 years of experience as an independent mold designer, working with a diverse range of customers—from small toolmakers to internationally operating mold manufacturers. Regardless of the size of the company, my commitment remains the same: delivering practical, manufacturable, and cost-effective mold designs that meet the highest standards.
I particularly enjoy challenging projects. Complex mechanisms, demanding technical requirements, and designs that seem impossible at first are the kind of challenges that motivate me. Finding smart, practical solutions is what makes mold engineering so rewarding.
At XactMould, every project receives my personal attention. You work directly with the engineer responsible for your design, ensuring clear communication, fast response times, and a smooth development process from start to finish.
What I value
- Honest advice, even when it means saying no.
- Clean engineering — moulds that are easy to run and maintain.
- Long-term relationships over single transactions.
