What Rotomachinery Group does

Rotomachinery Group designs, builds, and installs rotational molding machines and accessories for processing thermoplastic materials into hollow bodies of varied size and shape. The group's core platform consists of multiple machine architectures — Independent Arms (PRM Series), Fixed Arms Carousel, Shuttle SRM, Rock & Roll HRM (for very large items exceeding 40,000 liters), the PRM 900 Box Line for high-volume small articles, the LRM Laboratory Series, and the space-efficient SLIMLINE line — complemented by a modular accessory layer (dosing systems, powder transport, turbomixers, platforms, Tecnoplate, C-arms, square arms) and an integrated Complete Production Line System. Underpinning the hardware is the RMG ZONE technology platform, which bundles proprietary energy-efficiency systems (REGEN mechanical-friction energy regeneration, ECOMODE burner shutoff, Three Ways Box heat recovery, optimized oven ventilation), AI-processed infrared thermal-camera monitoring, and predictive-maintenance and production-planning tooling, along with a patented hybrid gas/electric regulation method.

The group operates two wholly-owned manufacturing sites — Polivinil Rotomachinery S.p.a. in Cerano, Italy (European headquarters) and STP Rotomachinery INC in Sherbrooke, Canada (North American operations) — and has installed more than 1,600 rotational molding plants across 100 countries over a 50+-year history. Revenue is generated through hardware sales (new and certified used machines plus optional equipment) and professional services, including custom design and implementation, customer-witnessed machine testing, operator training, and after-sales support and consulting. In October 2025, the group layered a machine-rental channel on top of direct capital sales through partnerships with financial institutions, expanding access for budget-constrained molders. Customer segments span industrial manufacturers (large containers and tanks), agricultural and gardening, sanitary and water treatment, furnishings and nautical, and — newly — clean-energy infrastructure via hydrogen storage tank-capable equipment.

The company sells primarily through direct enterprise field sales, with custom consultation-based pricing on multi-year contracts, supported by participation in industry conferences such as ROTOPLAS 2026 and ARMO 2027, plus a content-marketing website and presence across LinkedIn, YouTube, Facebook, and Instagram. Rotomachinery is privately held with no disclosed external funding, parent entity, or revenue figures.
