Company operations on one Southwest Indiana campus
The campus includes primary manufacturing and a dedicated medical facility. Engineering, tooling support, production, quality, and program management work across these operations.
Program teams coordinate part requirements, production planning, and quality records.
See how Infinity evolvedStart with function
Geometry, material, tolerance, environment, and downstream use shape the manufacturing approach.
Build repeatability
Equipment, automation, tooling, and process windows are aligned around stable production.
Measure at the source
On-site inspection and certified systems connect evidence to the people making the product.
Stay accountable
Program knowledge remains accessible from early review through launch and ongoing improvement.
Manufacturing approachFour areas of program work
How a molding program moves from requirements to ongoing production
Program review covers application requirements, design for manufacturability, process control, and support after launch.
Select a commitment
Review application and manufacturing requirements
Application conditions, geometry, resin, tolerance, volume, validation, and downstream operations are considered together so the manufacturing brief reflects the real program.
- Application-led review
- Material and tolerance context
- Clear technical ownership
One Mount Vernon campusSpecialized where it matters
Two manufacturing facilities with shared technical resources
The primary manufacturing operation and dedicated medical facility have distinct production environments. Engineering, quality leadership, environmental management, and customer communication are shared across the campus.

Manufacturing teams and their technical responsibilities
Engineers, production technicians, tooling staff, and quality teams review part requirements and production results. Their work includes molding process setup, automation, tool maintenance, and dimensional inspection.
Cross-functional review / One shared program context
Engineering and quality decisions stay grounded in the way the part is actually made.
Focused teams and accessible leadership help technical questions reach the right owner quickly.
Tool history, process evidence, and improvement work build useful knowledge across the life of a program.
Partnership beyond launchProgram memory matters
Support after launch for tools, processes, and program changes
Ongoing work includes preventive maintenance, engineering review of revisions, secondary operations, and quality response as program requirements change.
