Our culture

“Fun” and “cool” aren’t words typically used when describing a plastic injection molding company, but that’s exactly what we hear from our visitors, customers, and employees. We challenge each other, we hold each other accountable for doing the right thing, and if something isn't right, we work together to fix it. We have a passion for what we do and for finding new ways to do things better. Our management has built a strong trust that empowers every employee to learn, better themselves, and bring new ideas to the table - in turn, improving the products we make. Our dedication increases your competitive advantage.
