From design to delivery, SG PROTO offers a fully controlled prototyping workflow. Our process includes material sourcing, engineering review, precision machining (CNC, 3D printing, vacuum casting), surface finishing, and final inspection—ensuring every part meets exact specifications in both function and appearance.

High-precision CNC machining of aluminum parts ensures lightweight strength, tight tolerances, and superior surface finishes. From rapid prototypes to complex geometries, our advanced machining capabilities deliver reliable, high-performance aluminum components for aerospace, automotive, and industrial applications.

EPP foam prototypes offer an ideal solution for early-stage product development where lightweight design, durability, and impact resistance are essential. Widely used in automotive, packaging, and industrial applications, EPP materials closely simulate mass-production performance. With flexible density options and small-batch production, EPP prototyping helps accelerate design validation and reduce development risks.

Discover how brushed finishing effectively conceals scratches on metal prototypes. Learn why this cost-effective surface treatment is ideal for aluminum, stainless steel, and brass parts in appearance prototypes and display samples.

Titanium alloy prototypes offer exceptional strength, lightweight performance, corrosion resistance, and heat stability, making them ideal for high-demand product development and real-world functional testing across aerospace, medical, robotics, and advanced engineering industries.

SG PROTO specializes in low-volume CNC metal turning, providing global customers with a fast and economical bridge from prototyping to production. By leveraging advanced CNC lathes and expert engineering, we deliver high-precision components with strict tolerances and superior surface finishes across a variety of metals, including aluminum, titanium, and brass.

Rubber paint, also known as soft-touch coating, is widely used in prototyping for appearance models and display prototypes. Applied on plastic and metal parts, it improves surface texture, grip, and visual quality for consumer electronics, automotive interiors, medical devices, and industrial prototypes.

PVD (Physical Vapor Deposition) is a high-end surface finishing process widely used in prototyping to achieve mass-production-like appearance and improved wear resistance. This article explains what PVD is, why it suits appearance and functional prototypes, its limitations, and common applications in consumer electronics, automotive interiors, and medical devices.
