Engineering services with disclosed markup
Polynexus is built around four practice lines — a capital project, a parts program, a material qualification, an audit. Each is delivered by engineers, scoped on paper, and priced without surprise.
§ 01.01
Specification alignment, vendor down-selection, factory acceptance test (FAT) supervision, and commissioning support for blown film, cast film, extrusion, recycling, and converting lines.
— Project-based engineering services
§ 01.02
Qualified-vendor matrices for screws, barrels, screen packs, gearboxes, and other wear parts — multi-vendor bake-offs and ongoing PO management at a fraction of Western OEM pricing.
— Recurring program with disclosed markup
§ 01.03
Lab-validated, lot-traceable supply of screen mesh, additives, masterbatch, and specialty resins — qualified by spec, not by catalog.
— Per-lot QA + COA documentation
§ 01.04
Independent on-site supplier qualification, environmental and financial due diligence, and pre-shipment inspection — delivered by engineers, not agents.
— Fixed-scope engagement

Opaque commissions
Every line item disclosed. Our clients model our economics. We earn the next engagement on results.
A one-hour scoping call is the right first step. We'll listen to where the line is bottlenecked, where Western OEM pricing is biting, and what a credible Asian alternative would have to look like to be worth your engineering time.
