Prototyping & New Product Design

Why work with us

BACH INDUSTRY AG is your single partner for concept-to-production hardware. We unite industrial design, mechanical engineering, DFM/DFA, rapid prototyping, and bridge manufacturing under one roof—so your team moves from POC → EVT → DVT → PVT without friction.

• Speed without surprises: clear lead times, manufacturability feedback up front, and rapid change cycles (ECR/ECO).

• Precision & quality: tight tolerances, full metrology, and documented traceability (FAIR, PPAP on request).

• IP & security: NDA/NNN ready, controlled data access, revision control for CAD and drawings.

• EU-centric logistics: Switzerland/DACH operations, customs documentation, Incoterms EXW/FCA/DAP/DDP.

What we build

• Functional prototypes (mechanical, mechatronic, and electronic enclosures)

• Pre-series & pilot builds (bridge production, low-volume assemblies)

• Jigs, fixtures & gauges for validation and production ramp-up

• Reverse-engineered parts from drawings or 3D scans

• Design-to-spec / build-to-print components and subassemblies

Services across the product lifecycle

Design & Engineering

• Simulation: FEA, CFD, Moldflow, topology optimization, thermal & vibration analysis

• BOM and drawing package preparation, revision control, PDM/PLM integration

Rapid Prototyping & Fabrication

• CNC machining: 3-axis, 5-axis, turning, Swiss turning; EDM (wire & sinker), grinding

• Sheet metal: laser/waterjet cutting, bending, stamping, deep drawing, welding (TIG/MIG), brazing

• Polymers & elastomers: vacuum/urethane casting, injection molding (soft/bridge tooling), overmolding, insert molding, thermoforming

• 3D printing: FDM/FFF, SLA/DLP, SLS, MJF, DMLS/SLM (metal), binder jetting; large-format and end-use parts

• Heat treatment, case hardening, nitriding

• Laser engraving, pad/silk screen printing, PEM and heat-set inserts

Precision, tolerances & standards

We work to GD&T (ASME Y14.5) and ISO 2768/8015 practices, including flatness, perpendicularity, concentricity, parallelism, true position, and surface finish (Ra). Typical prototype tolerances meet tight-tolerance machining requirements; we’ll flag risk areas and propose tolerance relaxations or datum changes where appropriate.

Inspection & documentation

• CMM inspection, 3D/blue-light/laser scanning, CT scanning for internal features

• Complete inspection reports (FAI/FAIR), SPC/Cpk where required

• Material certs to EN 10204 3.1, RoHS/REACH declarations, lot traceability

Electronics & mechatronics (optional scope)

• PCB/PCBA prototypes (SMT/THT), firmware flashing & functional test jigs

• EMC/EMI considerations, shielding strategies, enclosure IP67 sealing

• Cable/wire harnesses, custom connectors, system-level fit-checks

Compliance & quality systems

Manufactured under ISO 9001 workflows; sector add-ons available on request (ISO 13485, AS9100, IATF 16949 partners). Support for CE, UL, FCC, UKCA, UL94 flammability, environmental testing (HALT/HAss, thermal cycling, vibration, drop, salt spray per ASTM B117), and biocompatibility (ISO 10993) via qualified labs.

Data, files & security

• Native and neutral formats: STEP/IGES/Parasolid, DWG/DXF, STL/OBJ, Gerber/ODB++/IPC-2581

• Secure transfer, NDA/NNN, controlled access, revision tracking, redline support

• Clear ECO/ECR paths and documented changes between T0/T1 and subsequent iterations

Industries we serve

Medical devices, aerospace & defense, automotive, industrial equipment, robotics & automation, consumer electronics, lab instruments, marine, energy, oil & gas, chemical processing, food & beverage equipment.

Logistics & geography

Switzerland-based with DACH/EU coverage. We manage customs, HS codes, EORI, and ship under Incoterms EXW/FCA/DAP/DDP. Consolidated packaging and serialized lot labeling available for pilot builds and field trials.

Typical use cases

• 5-axis CNC aluminum 6061 prototype housings with Type III hard anodize

• DMLS titanium brackets for topology-optimized lightweighting

• SLS nylon PA12 functional components for EVT fit/functional tests

• Soft tooling for small-batch injection-molded enclosures with overmolded seals

• Sheet-metal IP67 enclosures with powder coat and laser engraving

• CMM + FAIR for PPAP Level 3 build-to-print parts

• Reverse engineering from 3D scan; tolerance stack-up and DFM redesign

How to engage

1. Share your package: STEP + drawings (with GD&T), BOM, target quantities, material/finish, and critical features.

2. DFM review: we return risks, suggestions, and lead-time/cost options (standard vs. expedite).

3. Prototype build: T0/T1 samples, inspection reports, and test feedback loop.

4. Pilot run / bridge production: ramp-up plan, control plan, and supply schedule.
