When a product leaves the prototyping workshop for the production line, the language of information changes: what lived in the design engineer's head must become writing that means the same thing on the night shift, in the tool room and at incoming inspection. PBDP's technical documentation and manufacturing preparation service exists for exactly this — dimensioned production drawings, bills of materials, assembly instructions and the package that genuinely makes a product manufacturable. Our handover is orderly enough that if you outsource production tomorrow, nothing has to restart from zero.

What manufacturing documentation is and why mass production needs it

A production document set typically covers 2D drawings and 3D models for every part, a multi-level bill of materials (BOM), process sheets and station work instructions, inspection plans and test methods. Without them a factory stays dependent on one person, changes leave no trace and rework scales with volume. This package usually continues programmes that reached maturity through prototyping and functional testing.

What you receive in a documentation package

• Production drawings: dimensions, tolerances and geometric tolerancing to ISO convention — citable on the shop floor and in inspection reports.
• Bill of materials and specs: multi-level BOM with surface finishes and qualified alternate suppliers.
• Fabrication and assembly instructions: step-by-step station documentation with images and the correct part sequence.
• Tooling and mould documentation: the inputs mould design and manufacturing and special fixtures require.
• Quality control plan: inspection chart, test method and sampling level for every characteristic.
• Product-facing documents: technical catalogue, labels and packaging artwork kept in sync with production data.

Manufacturing preparation, step by step

1. As-is audit: collecting files, samples and the team's tacit knowledge; where nothing survives, we reconstruct through reverse engineering.
2. Standards and templates: unifying title blocks, numbering and revision levels across every document.
3. Drawing and modelling: re-drawing from real measurement, aligned with the product's industrial design intent.
4. Manufacturability review: documents corrected against machining cost and capacity, with an independent technical audit.
5. Line-side validation: a pilot run, documentation training for supervisors and recorded feedback.
6. Handover and version control: a searchable archive and an engineering change (ECN) procedure so the next revision creates no chaos.

Documents stop defects from repeating

Most production failures are not technical impossibilities; they come from ambiguity or scattered information — an obsolete drawing on a station bench, or a characteristic only a retired technician knew. That is why revision history and a single source of truth are mandatory in our packages: one central archive holding the only valid version of every document, with traceable distribution to the floor. Critical parts — anything touching safety, certification or warranty — get complete records: material certificates, heat-treatment parameters, coating specs and test methods. Deliveries arrive in native CAD formats, and where the client's network requires it we connect document access to the enterprise portal so line supervisors always see the latest revision on the internal network.

Frequently asked questions

What is the minimum documentation needed to start production?

Toleranced drawings for every manufactured part, a complete BOM with materials and finishes, and assembly instructions for the work stations. Inspection plans and process descriptions follow; with those three in hand, a first production batch is executable.

We have an old product with no surviving documents at all.

We rebuild it through reverse engineering: measuring and scanning existing parts, extracting the BOM, re-drawing to the manufacturing process that actually runs today, and validating with a pilot batch. The final delivery is the standard production document package.

How are product changes handled after handover?

Through engineering change control (ECN): every change is logged with a request form, impact assessment, approval and a new revision number; the old version is archived and the new one reaches every point of use automatically, so the line always works from one agreed version.
