This repository is the source of truth for the +project: planning documents, cost data, and — as the factory takes shape — +the data and software used to run it. + +## Vision: Full-Service Production + +The goal is the complete vinyl production chain under one roof, from audio +file to finished record: + +1. **Mastering** — audio mastering for vinyl +2. **Lathe cutting** — cutting the master disc +3. **Silvering** — metallizing the cut master +4. **Stamper production** — electroforming nickel stampers in-house +5. **Pressing** — extrusion and pressing of the finished records +6. **Finishing** — trimming, labels, shrink wrapping + +In-house galvanics (steps 3–4) removes the dependency on overseas stamper +suppliers — a common bottleneck for pressing plants — and shortens turnaround +for clients. The current planning documents cover the pressing line (step 5–6) +in detail; equipment and budgets for mastering, cutting, and galvanics are +open planning items. + +## Project Status + +**Planning stage** (as of mid-2026). + +- Industry outreach has been ongoing for several years — equipment vendors, + material suppliers, and independent consultants. +- Alexander and Simona will soon travel to + [Making Vinyl](https://makingvinyl.com/) in Haarlem, Netherlands, to gather + further insights from the pressing industry. +- A collaboration with [Resurrec](https://www.resurrec.com/) is under + discussion. + +## Pressing Line: Equipment Plan + +The core pressing 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; 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 planning 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. + +## Sustainability + +Two commitments are fixed design requirements for this plant, not aspirations +to be traded away during engineering: run on as much renewable energy as +possible, and discharge no contaminated water. Both are decisions we can +actually make, because the two biggest utility systems — steam and cooling — +are explicitly excluded from the Newbilt scope and will be sourced and +installed locally in Thailand. That gives us a free hand to spec them green +from day one. + +### Renewable energy — large solar installation + +The pressing machinery itself is a modest electrical load: 32 kVA connected, +~21 kW average for a full Duplex line. The real energy demand sits in the +utilities around it — above all the steam generator (400 kg/h saturated steam +at 10 bar / 180 °C) and the 250 kW cooling system. + +- A large rooftop/ground PV installation is planned. Northern Thailand's solar + irradiance is favorable, and daytime-heavy production shifts align well with + PV output. +- The machine load and cooling system are straightforward PV targets. +- Steam is the open engineering question: options under evaluation include an + electric boiler (maximizes the solar share), a biomass boiler (locally + abundant fuel), and solar-thermal pre-heating of boiler feedwater. No + technology choice has been made yet; it will be driven by honest numbers on + load profiles, storage, and grid backup — not by what sounds greenest. +- System sizing (kWp, storage, grid-connection model) is open until the site + is chosen. + +### Zero contaminated water + +The reference process schematic shows a conventional open "dirty water" +cooling loop. We will not build it that way. + +- Cooling (up to 250 kW, 220 l/min peak — ~98% of it mold cooling) will run as + a closed loop with a cooling tower/chiller, so process water is recirculated + rather than discharged. +- Steam condensate will be recovered and returned to the treated feedwater + cycle instead of being dumped. +- The planned in-house galvanics line (silvering and stamper electroforming) + involves plating chemistry — silver solutions and nickel baths. This is the + hardest part of the zero-discharge commitment: rinse water will need + closed-loop treatment and metal recovery, designed in from the start rather + than retrofitted. +- Solvent handling (flagged in the site requirements) will be contained and + disposed of as controlled waste — never via wastewater. +- Target: no process-water discharge to the local environment. Detailed water + balance and treatment design are pending site selection. + +### Materials + +The plant design already includes a PVC recycling loop: an in-house grinder +returns trimmings and rejects to the extruder, with the standard feed mix at +80% virgin / 20% recycled compound. Record scrap becomes feedstock, not +landfill. + +For the virgin compound itself, the preference is **local (Thai/regional) +PVC sourcing if the quality meets vinyl-record specifications**. The current +supplier list (2021) is entirely European plus one US option; qualifying a +local compound would cut shipping distance, cost, and the carbon footprint of +the feedstock. European suppliers remain the fallback where quality demands +it. + +## Worker Safety + +Worker safety is a founding priority, on equal footing with the environmental +commitments: + +- **Safety training** — proper, structured training for all operators and + maintenance staff, starting with the vendor-led commissioning training and + extending into an ongoing in-house program. The pressing line combines + hydraulics (~180 bar), saturated steam (10 bar / 180 °C), and hot PVC — + every one of these demands trained, deliberate handling. +- **Clean rooms for galvanics** — silvering and stamper electroforming will + run in dedicated clean rooms with controlled access, proper ventilation and + exhaust, and decontamination procedures for people and equipment leaving + the area. Plating chemistry stays inside its containment. +- **Personal protective equipment** — appropriate PPE (overalls, gloves, + goggles, and process-specific protection) is mandatory per work area, in + line with the equipment vendor's site requirements (exhaust work benches, + fire protection) and local regulations. + +Safety infrastructure — training program, clean-room specification, +decontamination workflow — will be planned alongside the equipment, not after +it. + +## Repository Layout + +``` +docs/ +├── consulting/ Consultancy proposals and overviews +├── equipment/ +│ └── newbilt/ Offers, site requirements, process schematic, service rates +├── finance/ Project cost overviews +└── suppliers/ PVC compound supplier contacts +``` + +Documents are primary sources (vendor PDFs and spreadsheets) and reflect the +state of negotiations at their file dates — treat prices and lead times as +snapshots, not commitments. + +## Roadmap for This Repo + +- Accumulate planning and vendor documents as decisions firm up — including + the mastering, cutting, and galvanics chain +- Add structured data (inventory, orders, production batches) once operations + begin +- Host the software/tooling built to run the factory (tracking, ERP-style + workflows)
