Manufacturing & OEM Engineering Support

Manufacturing support is about getting real-world production results: stable output, consistent quality, reduced downtime, and equipment that can be built, assembled, and maintained without drama. Barair Systems Limited provides practical engineering support to manufacturers and OEMs who need to design new equipment, improve existing machinery, resolve quality escapes, or accelerate delivery when internal resource is stretched. We work across design, verification, documentation, supplier coordination, and implementation support, always with a focus on what happens on the shop floor. If you need a senior Chartered Mechanical Engineer who can diagnose issues quickly, turn them into clear engineering actions, and support execution, this service is designed for you.

Typical problems we solve

  • You have production issues (downtime, scrap, rework) and need a structured engineering route to stabilise performance
  • Design-for-manufacture (DFM) gaps: parts are difficult to machine/fabricate, assembly is awkward, or tolerances are unrealistic
  • Drawings/specifications are inconsistent, incomplete, or not suitable for suppliers
  • A customer requires stronger documentation: calculations, evidence packs, sign-off notes, or traceability expectations
  • A design is overweight/overbuilt and needs rationalisation while maintaining safety margins
  • Quality escapes caused by poor datum strategy, adjustment drift, or tolerance stack-up
  • New product introduction: you need fixtures, jigs, gauges, or new tooling quickly
  • OEM equipment is being modified in the field and you need controlled engineering changes
  • Supplier management: technical queries are slowing progress and causing ambiguity

How we work

  • Define the target
    We agree what success looks like: throughput, quality, reliability, delivery, compliance evidence, or cost reduction.

  • Gather and review inputs
    Drawings/CAD, BOMs, test data, NCRs, field issues, supplier feedback, and production constraints.

  • Engineering assessment and prioritisation
    We identify the true constraints and rank actions by impact vs effort (and required downtime).

  • Design-for-manufacture / design-for-assembly
    We improve datum strategy, tolerances, access, fastener strategy, weld details, and assembly sequence to make production repeatable.

  • Verification where needed
    Targeted checks (hand calculations and/or FEA) are applied to confirm strength, stiffness, stability, and joint integrity.

  • Documentation and drawing pack
    We produce or refine drawings/specs so suppliers can manufacture consistently and you can maintain traceability.

  • Supplier and build support
    We answer technical queries, close out ambiguities, and maintain design intent through manufacture and assembly.

  • Implementation support and close-out
    We support commissioning/trials, confirm performance improvements, and document changes for future control.

Deliverables (what you receive)

Depending on scope, you may receive:

  • Engineering findings summary with prioritised actions (impact vs effort)

  • Improved drawings and manufacturing-ready detail packs

  • Tolerance and datum strategy recommendations (with practical assembly implications)

  • Verification checks and evidence packs (hand calcs and/or FEA summary as appropriate)

  • Supplier clarification support (technical queries closed quickly and clearly)

  • Installation/commissioning support notes and change-control records

  • Optional “as-built / as-modified” close-out summary

What we need from you (inputs)

To work efficiently, we typically ask for:

  • CAD models/drawings and current revision status

  • BOM and critical part specifications (materials, finishes, coatings, heat treatments)

  • Current performance issues (downtime, scrap, failures) and any supporting evidence (photos, NCRs, measured data)

  • Production constraints (shift patterns, planned downtime windows, critical delivery dates)

  • Supplier list and any current supplier feedback or problem areas

  • Acceptance criteria: what you need to achieve (quality, throughput, compliance, cost)

  • Any customer or insurer documentation requirements (where applicable)

Where this service is most valuable

  • When you need senior engineering capability without the overhead of recruiting

  • When production is unstable and you need rapid diagnosis plus practical implementation

  • When you are scaling manufacture and need DFM/assembly repeatability tightened up

  • When your customer requires stronger evidence and documentation for sign-off

  • When field modifications are happening and you need controlled, documented changes

Typical deliverables

  • Engineering findings summary with prioritised actions (impact vs effort)

  • DFM/DFA improvements: datum strategy, tolerances, assembly sequence, access and serviceability

  • Manufacturing-ready drawing pack and specification notes for suppliers

  • Verification checks where required (strength/stiffness, bolts/welds, stability; FEA summary if appropriate)

  • Supplier liaison and technical query resolution to maintain design intent

  • Close-out summary and change-control notes (as-built / as-modified where required)
