🔹 Technologies & Capabilities
CNC Machining
CNC machining ensures high-precision prototypes with tolerances up to ±0.01mm, suitable for both simple and complex geometries. It supports a wide range of metals and plastics, including aluminum, steel, brass, ABS, and POM, enabling prototypes that are durable and production-ready.
With smooth finishes and strong mechanical properties, CNC machining is ideal for functional testing, engineering validation, and end-use parts that require stability, accuracy, and reliability before mass production.
3D Printing
3D printing provides rapid prototyping without tooling, producing complex geometries with a fast turnaround. It is widely used for concept models, design validation, and functional prototypes where intricate structures are required.
Common materials include resin, nylon, ABS, and TPU, offering flexibility in transparency, strength, and elasticity. With quick delivery and design freedom, 3D printing shortens development cycles and enables testing of innovative designs before committing to traditional manufacturing methods.
Vacuum Casting
Vacuum casting enables small-batch production with surface quality close to injection molding. It is highly cost-effective for testing prototypes, marketing samples, or bridge production before large-scale manufacturing. Materials often include PU, ABS-like resin, and transparent resin, replicating the look and performance of molded parts.
With flexibility in color and texture, vacuum casting helps evaluate product appearance and functionality at a lower cost while keeping lead times short, making it ideal for pre-launch validation.
Injection Molding
Injection molding with prototype tooling allows parts to be made from real production materials such as ABS, PC, PP, POM, and nylon. This process ensures prototypes reflect the exact properties of mass-produced components. It is well-suited for functional testing, pilot runs, and small-scale validation before scaling up.
With consistent quality, repeatability, and material performance, injection molding provides an accurate preview of end-use results, supporting smoother transitions from prototyping to full production.

🔹 From Prototype to Low Volume Production
RALLY bridges the gap between prototypes and mass manufacturing. After prototypes are validated, low-volume production can be arranged with the same materials and processes used in final manufacturing. This approach minimizes redesign risks, ensures consistency in quality, and allows faster market entry. Ideal for pilot runs, product testing, and early market release.
🔹 Prototype to Production Path
Prototype → Fast prototypes in 3–7 days for design validation
⬇
Pilot Run → Small batches for testing assembly, function, and appearance
⬇
Low Volume Production → 100–5,000 pcs with consistent quality and real production materials
⬇
Mass Production → Seamless scale-up with stable processes and cost efficiency
Result: Faster time-to-market, lower risk, and cost-effective transition from idea to final product.
