Product Design for Manufacturing — From Prototype to Production
Guenzo helps product companies turn ideas, sketches and prototypes into manufacturable mechanical designs. We focus on designs that suppliers can quote and produce — not just good-looking CAD models — with the right tolerances, materials and assembly methods for your target manufacturing process.
Who this service is for
- Startups developing physical products
- Industrial designers needing a mechanical engineering partner
- Companies preparing a new product for first production batch
Problems we solve
- Prototypes that work, but cannot be quoted by real suppliers
- Unclear tolerances, materials and finishes
- Cost surprises when moving from prototype to first batch
- Too many parts, fasteners or assembly steps
Deliverables
- Production-ready 3D CAD models and assemblies
- DFM review with manufacturing recommendations
- Material and process selection
- Manufacturing drawings, BOM and assembly instructions
- Supplier-ready file packages (STEP, DXF, PDF)
- Prototype iterations between design rounds
Software we use
- SolidWorks (parts, assemblies, drawings, sheet metal, weldments)
- SolidWorks Simulation (FEA) for stress and deflection checks
- DraftSight / AutoCAD for 2D drawings and DXF
- KeyShot for product renders when required
- PDM / shared cloud folders for revision control
Supported manufacturing methods
- Injection moulding (with mould-aware geometry)
- Sheet metal: laser, bending, welding, powder coating
- CNC milling and turning
- 3D printing for prototypes and low-volume end-use parts
- Hand and jig-based assembly
Example projects
- Consumer electronics enclosure prepared for injection molding
- Sheet metal industrial product prepared for laser + bending suppliers
- Mechanical assembly for a startup's first production run
- Redesign of an existing product to reduce part count and cost
Process
- Discovery: Requirements, target cost, volumes, manufacturing method.
- Concept CAD: Layout, key dimensions, fit and clearances.
- DFM iteration: Refine for the chosen process (CNC, sheet metal, molding).
- Production package: Drawings, BOM, STEP/DXF, supplier handover.
Frequently Asked Questions
Can you help turn a product idea into manufacturable CAD files?
Yes. We work with sketches, mood boards, industrial design surfaces, and 3D-printed prototypes and turn them into manufacturable CAD with drawings and a BOM.
Can you support our transition from prototype to first production batch?
Yes. We prepare DFM-ready CAD, drawings and supplier documentation, and stay involved during quoting and first article inspection.
Do you work with companies outside Latvia?
Yes. We work remotely with companies across Europe and internationally. Most projects are run by email, video calls, and shared cloud folders.
What CAD file formats can you deliver?
Native SolidWorks (SLDPRT, SLDASM, SLDDRW), STEP, IGES, Parasolid, STL for 3D printing, DXF for laser/waterjet/sheet metal, and PDF manufacturing drawings.
Can you sign an NDA before we share project details?
Yes. We routinely sign NDAs before reviewing concepts, sketches, or existing CAD data.
