Prototype to production
Our Manufacturing Facilities
CNC machining, composite forming and supporting metal processes are coordinated around each part. Tooling, secondary operations and inspection are planned from the drawing.
About GrancenOur process
From Drawing to Delivery
Four stages of project coordination, from drawing review to manufacturing, inspection and delivery.
Drawing Review
Share the drawing or 3D model, material, quantity, finish and inspection requirements.
Process Planning
Review geometry, interfaces, process selection, tooling or mold requirements and open technical questions.
Manufacturing
Produce parts using the agreed process, with checks focused on critical features and process risks.
Inspection & Delivery
Check agreed dimensions, tolerances and finish, then arrange protective packaging and delivery.
Composite process selection
Carbon Fiber Manufacturing Processes
Fiber form, resin introduction, tooling, compaction, geometry and production quantity guide the choice of carbon fiber process.

Prepreg Compression Molding
Directional continuous prepreg in matched heated tooling under a controlled press route.
Vacuum-Bag & Autoclave Curing
Continuous lay-up sealed under vacuum; an autoclave route adds controlled external pressure.
CF-SMC Compression Molding
Non-continuous sheet molding compound flows to form ribs, bosses and 3D geometry.
Quality management
Inspection to Your Specifications
Inspection is planned around the drawing, critical dimensions, tolerances and surface requirements. Suitable methods may include calipers, micrometers, gauges and coordinate measurement.
- Material: grade, batch and condition, where required.
- Process: agreed manufacturing or cure records.
- Finished part: dimensional, surface and appearance checks.

Custom Manufacturing FAQs
Clear inputs at the quotation stage help engineering teams review the process route, inspection scope and open technical points.
What files are useful for a custom manufacturing quotation?
Share the available 3D model and controlled 2D drawing together with the material, quantity, finish and inspection requirements. Common review formats include STEP, IGES, SolidWorks, DXF, DWG and PDF.
Which manufacturing processes can Grancen coordinate?
Current capabilities include CNC machining, composite forming, cold heading and fasteners, sheet metal fabrication, precision casting and related secondary operations. The route is selected around the part requirements.
Can a project move from prototype to production?
The manufacturing and inspection route can be planned around prototype, small-batch or production requirements. The exact tooling, process controls and delivery plan are confirmed after drawing review.
How is the inspection scope determined?
Critical dimensions, tolerances, surface requirements and reporting needs are reviewed with the drawing and manufacturing plan. Measurement methods are selected according to the agreed features and project scope.
