InDesignLabs service

Plastic Enclosures and Detailed Engineering

Develop enclosure systems and production CAD that preserve design intent while meeting tooling, assembly, sealing and tolerance requirements.

An enclosure is a mechanical system, not a decorative shell. It must locate components, manage forces, protect interfaces, assemble consistently and remain manufacturable without cosmetic defects. InDesignLabs develops plastic enclosures from external form through tooling-ready definition.

Resolve the invisible details that determine production quality

  • Integrate electronics, batteries, displays, controls and connectors within realistic space claims.
  • Create reliable joints, mounts, ribs, bosses, snaps, seals and fastener strategies.
  • Control wall thickness, draft, undercuts, sink, warp and parting-line implications.
  • Define tolerances and datums around the functional assembly.
  • Deliver revision-controlled CAD, drawings and BOMs that suppliers can manufacture.

What we do

  • Injection-moulded enclosure architecture
  • Handheld, desktop and medical-device housings
  • Internal component and PCB packaging
  • Part split, tooling direction and parting-line strategy
  • Wall, rib, gusset and boss development
  • Snap fits, clips, latches and living hinges
  • Threaded inserts, screws and fastening strategy
  • Gaskets, seals and ingress-protection features
  • Display, button, connector and battery integration
  • Ultrasonic welding, heat staking and adhesive joints
  • Drop-impact and local reinforcement design
  • Draft, undercut, sink and warp-risk reduction
  • Parametric part and assembly CAD
  • Tolerance stack-up and fit analysis
  • GD&T and manufacturing drawings
  • BOM, material and finish specifications
  • Tooling-ready data preparation

How the engagement works

  1. 01

    Package

    Establish space claims, interfaces, service access, environmental requirements and critical surfaces.

  2. 02

    Architect

    Define part splits, assembly direction, joints, fasteners, sealing and tooling strategy.

  3. 03

    Detail

    Develop production features, materials, tolerances, datums and drawings.

  4. 04

    Prototype

    Evaluate fit, access, assembly, stiffness, usability and visible quality.

  5. 05

    Support tooling

    Review supplier DFM, tooling proposals and trial parts, then resolve moulding and assembly issues.

Typical deliverables

  • Enclosure and internal packaging architecture
  • Tooling-oriented three-dimensional CAD
  • Detailed production drawings and GD&T
  • Tolerance and interface definition
  • Material, finish and joining specifications
  • Bill of materials
  • Prototype data and evaluation criteria
  • Supplier DFM responses and tooling corrections

When to engage InDesignLabs

For diagnostic devices, consumer electronics, controls, appliances and industrial products requiring injection-moulded housings or mixed-material assemblies.

Start a project

Share the industrial-design surfaces, PCB and component data, environmental requirements, production volume and target process. We can begin from a concept, legacy product or incomplete CAD assembly.
