What Smooth-Bor Plastics does
Smooth-Bor Plastics (legal entity Steward Plastics, Inc.) is a Southern California-based manufacturer of plastic corrugated hose and tubing founded in 1971, with operational headquarters at 23322 Del Lago Drive, Laguna Hills, CA and a second production facility in Johor Bahru, Malaysia. The company specializes in medical-grade tubing systems — particularly heated tubes for continuous positive airway pressure (CPAP) devices, breathing circuits, and ventilator/respiratory care applications — built on over 40 years of plastic extrusion and injection molding capability. Its product portfolio comprises seven distinct medical tubing lines (Style 103/105 through Style 903/905) plus proprietary FlexFilm™ material technology that underpins its next-generation consumer offerings. Smooth-Bor holds ISO 13485:2016 (expiry 9/17/2027) and CE Mark certifications, maintains a portfolio of US and international patents and trademarks, and operates the Smooth-Bor®, AltaFlex®, and AltaResp™ brands. Effective March 4, 2025, Smooth-Bor joined Plastiflex Group N.V., which is intended to extend its product portfolio, add capabilities, and widen global presence; existing leadership (CEO Eric Carlson, President/CFO Steve Caiozzo, EVP Jennifer Carlson) and both production sites remain in place.
The company operates a hybrid commercial model. The dominant motion is B2B enterprise field sales to medical device OEMs and medical distributors on quote-based net 30 wholesale terms, with the company explicitly stating it sells to OEMs and Distributors only. A secondary direct-to-consumer motion was launched in 2021 (AltaResp) and expanded in 2022 (AltaFlex) to sell FlexFilm™-enabled CPAP tubing through the AltaFlex.us e-commerce storefront and Amazon, targeting end-user CPAP consumers. Revenue mechanics are entirely hardware sales with quote-based pricing and no public list pricing. Marketing and lead generation are concentrated on a content-rich website, regulatory documentation, and LinkedIn presence; the GTM approach relies on direct engagement with OEM procurement and engineering teams rather than mass advertising.
