A Kansas City Success Story: Solving the Impossible
A medical device innovator near the University of Kansas Medical Center was facing a major crisis. They had a complex design for a surgical tool housing that required extreme precision. Their previous vendor struggled with “sink marks” and inconsistent dimensions that made the parts unusable in a sterile environment. They were weeks behind schedule and their funding was at risk. They needed a specialist in precision injection molding for medical parts.
Serving this Kansas City, KS client from our Michigan facility, we immediately performed a professional mold flow analysis. We discovered the original gate placement was causing air traps. Our team redesigned the tool at our Michigan headquarters and implemented a decoupled molding process. Within three weeks, we delivered a batch of flawless, high-aesthetic housings. The client successfully launched their pilot program on time, proving that our Michigan-based operations provide the reliability KCK businesses need to win.

Frequently Asked Questions
How does shipping work for my Kansas City KS project
Logistics is a core part of our service. We use high-speed freight corridors to ship parts directly from our Michigan facility to your location in Kansas City. Most clients find that our production efficiency actually results in a faster total delivery time than local shops struggling with backlogs or equipment downtime.
Can you match my specific brand colors.
Yes. We offer professional coloration services. We can match any Pantone color or physical sample to ensure your brand looks consistent across every part. We handle this at our Michigan facility with the same precision we apply to the molding itself.
What happens if my part design has a flaw
That is where our expertise shines. We perform a technical review of every design before we cut steel. If we see a potential issue like poor draft angles or uneven wall thickness, we tell you immediately. This proactive approach saves KCK businesses thousands of dollars in rework.
Do you handle small production runs
Absolutely. We understand that not every project starts with a million units. We offer flexible production options to help you scale at a pace that fits your budget. Whether you need a few hundred parts for a test market or thousands for a full launch, we can help.
What is the risk of using a low-end molder
The biggest risk is mechanical failure. Low-end shops often skip the scientific data needed to ensure part strength. This leads to parts that break in the field, causing expensive recalls and damaging your reputation in the Kansas City business community.
