What Piper Plastics Corp. does

Piper Plastics Corp. is a privately held, family-owned custom plastics manufacturer founded in 1963 by Larry Weiss and now led by his son Andrew Weiss (Owner/Chief Engineer, MIT-trained) alongside President Ernesto Cabello (MIT-trained). The company operates a single 16,000+ square-foot manufacturing facility in Copiague, New York, running 19+ automatic computer-controlled dip molding and dip coating centers on a 24/7 schedule. Its core offering is plastisol (PVC) dip molding and dip coating for customer-supplied parts and proprietary mandrel-molded components, supplemented by fluidized bed powder coating (PVC and nylon), rotational molding, and plastisol casting. The technology base is built on in-house proprietary equipment — forced air convection ovens with ±1°F PID temperature control, z-axis motion controllers with .005-inch resolution, and custom-designed dipping tanks — all engineered internally by the MIT-trained team.

Piper serves enterprise B2B customers across medical devices (nasal cannulas, wound drain Y-connectors, spring-reinforced perfusion tubing, anesthesia masks, stethoscope tubing, endotracheal tubes), military/defense (A-A-59464 / MIL-P-20689 spec coatings for naval and army systems), electrical equipment (insulated connectors, water-tight fittings, battery covers), plumbing (ADA-compliant antimicrobial fittings), automotive (seat belt components), food service, and consumer products (tool grips, fishing lures, coated glassware). The business model is direct, quote-based custom manufacturing: prototype runs start as low as 100 pieces, production runs at 500-1,000+, with tooling lead times of 2-6 weeks and production lead times of 1-3 weeks. No software product, no API, no e-commerce — revenue is generated through direct sales engagement against custom RFQs. The company holds ISO 9001:2015, UL Registered Firm, REACH, RoHS, FDA food-contact, and USP Class VI certifications, and is the originator of the US military plastisol coating specification developed by founder Larry Weiss in the 1960s.
