What Whk BioSystems does
WHK BioSystems, LLC is a US-based contract manufacturer founded in 2012 in Clearwater, Florida, and operating as a subsidiary of the TSE Industries family of companies. The company designs and produces single-use assemblies, custom tube kits, transfer bottle assemblies, sanitary connections, and proprietary TPE and polypropylene tubing lines (W-TPE™ and ProFLo™) for the biopharmaceutical, life science, medical device, and emerging cell and gene therapy industries. Manufacturing is conducted in two ISO 13485:2016-certified Class 7 cleanrooms and is supported by a 12,000 sq ft climate-controlled warehouse.
The company's technical core is a vertically integrated stack of capabilities: medical tubing extrusion, cleanroom injection molding, overmolding (including a proprietary overmolded-connection technique that eliminates cable ties and barbed connectors), platinum-cured silicone/TPE sanitary molding, RF welding, laser cutting/engraving, design services from concept through 3D-printed prototyping, and most recently in-house UHMW sheet manufacturing via custom hydraulic presses for implantable medical device components. Inputs are formulated to meet USP Class VI, ISO 10993-5/6/10/11, FDA 21 CFR 177.1520, REACH, and RoHS standards, allowing qualification into regulated customer processes.
WHK operates a sales-led, project-based business model: revenue is generated through quote-based contract manufacturing engagements sourced via direct phone, email, contact form, and an emerging content-and-social marketing presence. Pricing is not publicly disclosed and varies by project. The company is privately held under family ownership with Robert Klingel Jr. as President and is part of TSE Industries, the Klingel family's ~60-year-old diversified manufacturing group. No outside venture capital, institutional funding, or M&A activity is disclosed, indicating an organic-growth operating posture.
