The Matrix Plastic Products Management Team
ANDY ZIEGENHORN, President & Chief Executive Officer
As President and CEO, Andy focuses on leadership, strategic planning, and the continued growth of Matrix Plastics Products. He knows our business operations from the ground up and continues to serve as the Program Manager for a couple of our key accounts. Utilizing key performance measures to make continuous improvements and exceed customers' expectations is Andy's primary focus.
Andy started working at Matrix as a part-time summer employee when he was 17. Following his tooling and CNC machining apprenticeship training, he migrated into a number of different roles over the years, (including IT, Sales & Marketing, and Internal Auditing) before assuming a key role in the Molding department in 2009.
As our molding business rapidly grew, Andy developed the Project Manager role as a liaison between customers, suppliers, and our technical team. He also helped design and implement our custom ERP system. In 2017 Andy stepped into the COO role, where he used his broad experience and understanding of the company to implement policies and actively lead the team in solving day-to-day challenges. By July of 2018, Andy was well prepared to assume the President & CEO role following the retirement of our co-founder, Paul Ziegenhorn.
What motivates Andy? “I like the big-picture strategy element of working at Matrix. It's kind of like a chess game to me. For a business our size, I am proud of how sophisticated we are in so many areas.”
Andy holds a B.A. degree in Marketing and Spanish from Marquette University.

As Chief Financial Officer at Matrix Plastic Products, Mark is directly or indirectly responsible for accounting, tax, HR and legal matters affecting the company, its shareholders and its employees.
Mark has been continuously involved with Matrix, either part-time or full-time, since 1979 when he was an undergraduate student at the University of Illinois – Chicago. After earning his B.S. degree in Accounting and his CPA certificate, Mark worked in public accounting for a Big 8 CPA firm while completing his Master's degree at DePaul University and maintaining his involvement at Matrix. Mark went on to work for 15 years as a corporate tax manager for a mid-size multinational company while also doing tax and financial consulting for other businesses and continuing to work part-time at Matrix.
As Matrix continued to grow rapidly, Mark left his corporate tax manager position and returned to Matrix full-time in 1999 to serve as our CFO, a role he has held ever since.
Mark’s breadth of experience is a tremendous asset to Matrix. As he says, "I've been very fortunate throughout my career to have job positions that exposed me to a wide variety of challenging responsibilities at larger companies.

Our employees have excellent opportunities to gain valuable experience through hands-on involvement in the business, and that translates into very rewarding job experiences.

HANS NOACK, Design Engineer
Hans is the mastermind who can take the most challenging print, part or model and design a mold to create that part and satisfy the customer. He routinely pushes the envelope and tests the limits of what can be achieved with plastic injection molding, having worked with an abundance of parts and processes throughout his career.
Hans brings well over 50 years of moldmaking and design expertise to our mold design and engineering team. When Hans began his career as an apprentice moldmaker in 1963, his previous school and work experience in architecture and drafting served him well.
In the years that followed, Hans perfected his craft and became a master moldmaker. He gained broad experience working with thermoset, compression, transfer and injection tools. After 14 years on the bench and as shop foreman at Abcor Molds and Woodland Molded Plastics, his extensive moldmaking skills prepared him to become a highly sought-after mold designer. In 1977, Hans became sole proprietor of his own mold design business, and Matrix soon became one of his biggest clients. In 1990, he brought his wealth of knowledge and expertise to Matrix as a full-time mold design engineer.
What does Hans like best about his job? “The general public has no idea where their products come from, but the world would not function without toolmakers. The pride I get from seeing the final product is my motivation going into the next project.”
