Since 1963, KOK has invested in advanced manufacturing equipment and process development to support production efficiency, repeatability, and long-term supply stability.
The molding department is completely in-house and operational 24 hours a day, 7 days a week.
Our molds are always produced with quality and longevity in mind. This is why we are trusted by manufacturers around the globe who require high quality, long-term availability for parts made to their specific requirements. An in-house molding department also means that we are able to turnaround prototypes in very short time-frames.

The machines we use in each production line allow us to produce and package products in the most efficient and cost-effective way. A number of our machines have been designed and made by our own designers in-house to support these efficiency requirements.

Specific products require specialized manufacturing environments to ensure durability, consistency, and long-term performance. KOK operates dedicated clean room facilities supporting healthcare, medical, and other applications requiring tightly controlled production environments.
KOK specialized capabilities include:
These capabilities set us apart from other manufacturers who can only produce products and have to source molds or send products out for treating and packaging.
Our process is complete from optimizing design to packaging your products.

For time-sensitive programs, feasibility is assessed based on tooling status, raw material leadtimes, and production load. When conditions allow, priority scheduling can be evaluated inalignment with customer requirements.
