Turn validated designs into repeatable production with engineering support, process control, and flexible manufacturing capabilities.
ISO 9001:2015 | ISO 13485:2016 | IATF 16949:2016
Production starts when a design is ready to move beyond validation. The focus shifts from making samples to controlling repeatability, process stability, inspection, and delivery.
Mastars supports production manufacturing for metal and plastic parts through CNC machining, injection molding, sheet metal fabrication, casting, and coordinated secondary processes. The right manufacturing route is selected based on geometry, material, tolerance, quantity, and production goals.
Low-volume production bridges the gap between prototypes and higher-volume manufacturing. It supports pilot builds, market launch quantities, engineering changes, and products with uncertain demand.
Mastars supports flexible low-volume builds from pilot quantities to 2,000+ parts before scaling into higher-volume production.
| Manufacturing Process | Production Volume | Typical Lead Time | Typical Capability | Best For | Tooling |
| CNC Machining | Low to Medium | Days to weeks | Tolerances down to ±0.005 mm; metals & engineering plastics | Tight-tolerance functional parts, housings, and structural components | No dedicated tooling |
| Injection Molding | Medium to High | Weeks after tooling | Injection precision up to ±0.01 mm; multi-cavity & overmolding options | Repeatable plastic parts and molded assemblies | Required |
| Sheet Metal Fabrication | Low to High | Days to weeks | Cutting, bending, welding, and integrated finishing | Enclosures, brackets, chassis, panels, and structural parts | Usually no dedicated tooling |
| Metal Casting | Medium to High | Project dependent | Near-net-shape metal parts with CNC finishing for critical features | Complex metal housings and production components | Process dependent |
| Plastic Tooling | Medium to High | Project dependent | Mold accuracy down to 0.002 mm; single & multi-cavity tooling | Injection mold development for repeat production | Required |
| 3D Printing | Low / Specialized | Days | Plastic and metal additive manufacturing for complex geometries | Customized parts, complex structures, and tooling-free production | No tooling |
A validated prototype is not automatically production-ready. Before production release, the project should have an approved CAD revision, confirmed materials and finishes, defined critical tolerances, an agreed manufacturing route, and clear inspection requirements. We review these factors for risks that could affect repeatability, assembly, tooling, or batch quality.
Yes. Mastars supports repeat low-volume builds as well as sustained higher-volume production. The most suitable process depends on part geometry, material, tolerance, tooling investment, and expected demand. CNC machining may be practical for lower recurring quantities, while molding or casting may offer better unit economics as volume increases.
Consistency starts with controlled requirements. Approved drawings, revisions, materials, finishes, inspection plans, and process requirements remain linked to each production run. First article, in-process, and final inspections help identify variation before it affects the rest of the batch or subsequent production runs.
Production inspection can include first article, in-process, dimensional, visual, and final inspection depending on project requirements. Dimensional verification can include CMM, optical measuring equipment, height gauges, and other inspection tools as required by the part and inspection plan. Inspection scope should focus on critical dimensions and customer requirements rather than applying the same inspection plan to every part.
Yes, depending on project requirements. Available documentation can include FAI, dimensional inspection, CMM inspection, and production quality records. If you require material certificates, CoC, PPAP, or other specific documentation, include it during quoting so the scope and availability can be confirmed before production.
Changes are possible, but they should be reviewed before the next production release. A revision may affect tooling, CNC programs, fixtures, material requirements, inspection criteria, cost, or lead time. Send the updated CAD model and drawing clearly marked with the new revision so the manufacturing impact can be assessed before production continues.
Yes. Production projects can combine CNC machining, injection molding, sheet metal fabrication, casting, finishing, and assembly where appropriate. Coordinating these operations within one project helps reduce supplier handoffs and keeps drawings, revisions, quality requirements, and delivery schedules aligned.
Start with your current CAD files, drawings, quantity, material, and finish requirements. For production projects, also include critical dimensions or GD&T, expected repeat demand, inspection requirements, and any assembly or delivery needs. Rough information is fine to start, but the latest approved drawings and revision details should be confirmed before production release.
