+# Pressing Line: Equipment Plan
+
+The target press fleet is a **50/50 split between fully automated and
+semi-automatic presses**: automated presses for standard production volume,
+and semi-automatic presses for splatter and other color effects, special
+editions, and small runs, where an operator working the mold directly is an
+advantage rather than a cost. The semi-automatic side is covered by the
+Newbilt evaluation below; a fully automated press line is an open
+procurement item (see the [vendor landscape](../suppliers/vendor-landscape.md)
+for the Pheenix Alpha candidate).
+
+## Semi-automatic line: Newbilt
+
+The core semi-automatic machinery under evaluation comes from
+**Newbilt machinery GmbH** (Alsdorf, Germany):
+
+- **Newbilt Single 2.1 system**: one VEX 50 extruder feeding one HRP 12
+  hydraulic press (~150 t press force), pressing 12" records at 140 or 180 g
+  with a Newbilt book mold set. A Vario trimmer handles 12" cuttings, with
+  a 7"/10" upgrade path.
+- **Duplex upgrade path**: the hydraulic aggregate is already sized for a
+  second press, and an additional press and extruder are quoted options, so
+  the plant can scale from Single to Duplex without replacing infrastructure.
+- **Supporting equipment**: label dry oven, shrink wrapper, PVC grinder
+  (scrap feeds back as the ~20% recycled share of the feedstock), 7" center
+  label punch, buffer spindles and separator plates.
+
+The June 2024 Newbilt quotation totals **≈ €200,500** including freight from
+Alsdorf to Thailand and seaworthy packaging. Two major utility systems are
+deliberately excluded and will be **sourced and installed locally in
+Thailand**: a ~400 kg/h steam generator (with water treatment) and a ~250 kW
+cooling water system. The quotation has passed its validity date and will need
+re-confirmation before ordering.
+
+## Site requirements
+
+Site planning for the semi-automatic line works from Newbilt's Duplex
+requirements: roughly 200 m² of production floor, 32 kVA connected
+electrical load, saturated steam at 10 bar, and compressed air and cooling
+water circuits, plus side rooms for materials, compressor, chiller, and
+finished goods.
+
+Source documents live in [`newbilt/`](newbilt/): the budgetary offer, the
+Duplex site requirements, the process schematic, and the service rate card.
