HQC started manufacturing in 1987 with precision injection molding.

We have since then grown into a full-service custom molder and manufacturer of stock and custom closures serving the food, dairy, personal care, household and medical device industries.

Building on our early success, we have expanded our capabilities well beyond injection molding.

Our operations now include high-speed automated assembly, capping, lining, welding, decorating, prototyping and laser-marking. HQC customers also benefit from our state-of-the-art in-line vision inspection and automated packaging systems including a cobot station.

Our focus on design for manufacturing and scale allows us to move projects forward with consistent speed and discipline as we serve and solve for each customer.

HQC’s clean, modern manufacturing site is located outside of Chicago in Oswego, IL.

Where many companies remained focused on niche specialization, we saw how we could diversify beyond our core capability.

In doing so, we have been able to gain the knowledge, insight and equipment that can support different links in your chain of production. Our understanding of other suppliers’ roles and requirements allows us to help you save money, time and trouble.

Everything we do and develop is inspired and guided by what we have learned from listening to those we serve. That dedication creates enduring, trusting relationships across the manufacturing spectrum. Through the years, more than 90% of HQC sales have come from referrals from nationwide companies that have reached their goals with us.

To this day, when visitors tour HQC, the things they still say the most are how clean our facility is and how surprised they are at the different operations we can perform.  They also mention how engaging and interactive our employees are in greeting them and showing them what they are working on.

We uphold a commitment to safety and quality through third-party inspections and audits as well. HQC maintains Safe Quality Food Institute (SQF) certification for food safety, Interstate Milk Shippers (IMS) certification for dairy packaging and ISO 13485 certification for manufacturing medical devices.

Seeing you succeed fuels our desire to improve and innovate further. We will continue to grow and adapt according to what we discover and learn from different markets and from what you share with us about what you want to achieve for yours.
