Extrusion-Line Supply Boundary Matrix

Assign a proposed owner to each work package. Every choice remains provisional until it appears in the written quotation and acceptance documents.

Work package	Boundary question	Proposed owner
Raw-material preparation	Grinding, sieving, batching and ingredient release
Dosing and preconditioning	Feed accuracy, liquid addition and upstream controls
Extrusion core	Feeding interface, barrel/screw package, die interface and local controls
Die and cutting	Product geometry, cutter interface and change parts
Drying and cooling	Moisture removal, cooling target and capacity match
Conveying and packaging	Transfers, buffers, metal detection, weighing and packing
Site utilities	Power, water, steam, air, drains, ventilation and supports
Plant controls and data	Signals, protocols, historian/MES, remote access and cybersecurity
Installation and commissioning	Rigging, alignment, connections, dry checks and wet trials
FAT, SAT and acceptance	Test recipe, sampling, limits, witnesses and deviation closure
Cleaning and hazardous energy	Cleaning method, allergen changeover, isolation points and site LOTO
Training, spares and service	Operator training, spare-parts list, remote support and escalation

Choose proposed owners, then build the summary.

The matrix is a scoping aid, not a contract. Ownership changes only when both sides confirm it in writing.
