Speed, Efficiency, and Quality

PTI is a pioneer in the world of medical plastic injection molding with enhanced capabilities that can take their customers from concept through production.  Their 155,000 sq. ft. facility in Macomb, Michigan is home to some of the most advanced tooling and manufacturing systems in the industry.  PTI has a long, respected relationship within the medical community.  Working side-by-side with their medical partners, PTI continues to raise the bar with innovative technology and expertise that produces faster and more cost efficient solutions in the area of design, tooling, and plastic injection molding.

Design and Engineering

It starts with design; whether it’s new design or design assistance. Available to PTI customers’ is the full resources of PTI Design.  On site are designers and engineers that will ensure your concept is designed for manufacturability. From product development, material     recommendations, as well as, moldflow services, their team will help you get your concept from mind to manufacturing.

Tooling

Their highly skilled journeymen mold makers build both prototype and production tooling for extremely complex geometries requiring very tight tolerances.  PTI utilizes various materials to construct tooling including aluminum, all grades of steel and hybrids of both.  They have 16 high speed CNC machining centers, 2 high-speed graphite CNC machines and 3 CNC EDM machines.  The machining centers are tied in to the fully integrated tooling network and achieve spindle up to 54,000 RPM, requiring heat shrink collet tooling.  PTI is known in the medical industry for its highly detailed tools, multi-surface large parts, and scientific molding capability.  Their P3 proprietary process provides the quick turnaround and the competitive edge necessary in this market by producing a superior tool that will meet the requirements for prototype through production.

Molding

In PTI’s production facility their press sizes range from 12−500 tons of some of the most sophisticated equipment in the plastic molding industry. This range enables low and high volume production and the ability to produce complex and custom rapid injection molded products.  PTI also offers micromolding with low cost and short lead times. Micromolding uses a closed-loop manufacturing process where the raw material is conveyed to the molding machines by a mini material handling system.  Micromolding molds, similar to conventional hot-runner, runner-less molds, are built using the latest technology integrated CAD/CAM/CNC equipment, allowing PTI to reduce mold lead times by more than 50% compared to traditional mold making processes.

Cleanroom

Adhering to the strict protocol and methods, PTI meets the demands of industries requiring ISO Class 8, Class 100K Cleanroom specifications, including bioburden and electrostatic discharge (ESD). PTI is home to over 3,000 sq. ft. of Cleanroom manufacturing.
