Why Choose WHK?

There are thousands of “Medical Molders” out there to choose from, but many of these same companies are primarily focused on industrial products and the more relaxed quality and regulatory standards those applications require.

WHK Biosystems specializes in medical-grade applications and our regulatory experience, quality, and attention to detail set us apart from the rest.

Capable. Compliant. Quality.

With two, well-equipped Class 7 cleanroom manufacturing facilities, we have space and capacity to take your project from development to large-scale production. Whether your job is a small batch prototype or involves an ongoing mass production contract, we can meet your needs.
