The fastest finishing option. Parts are delivered with visible tool marks and may have sharp edges or burrs, which can be removed upon request. The surface typically corresponds to a 125 µin Ra finish.
A coating of liquid or powdered paint is applied to achieve a smooth, glossy, or clear finish. This method can enhance appearance and provide basic environmental protection.
A thin metal layer is applied to the part to improve durability, conductivity, and appearance. Creates a smooth and glossy finish while protecting against corrosion.
A mechanical finishing process that smooths and buffs the surface to achieve a reflective, glossy appearance. Reduces surface roughness and improves overall aesthetics.
Achieve tight tolerances from ±0.1 to 0.8mm. Excellent surface finishes. Expert mold-making ensures consistent quality.
Get parts delivered in 5-15 days. Cost-effective low-volume production. Flexible order sizes from 20-200+ parts.

Dimensional Testing
Dimensional testing uses CMM, digital calipers, height gauges, and micrometers to verify tolerances, geometric positioning, hole diameters, wall thickness, and fit dimensions.
Visual Inspection
Visual inspection employs magnifiers, roughness testers, and color charts to detect surface defects including bubbles, scratches, dents while ensuring color consistency and surface finish quality.
Paint Adhesion Testing
Paint adhesion testing validates coating bond strength, durability, and thickness uniformity for all finishing requirements.
4- and 5-axis machining is ideal for producing complex or highly detailed components that require tight tolerances, smooth transitions, and precise geometry. When your part involves intricate features, multi-sided machining, or demanding accuracy, 5-axis machining is the best choice.
The maximum workable size for 4- and 5-axis CNC machining is 1200 × H1000 mm, allowing large and complex parts to be produced with precision.
Choose 4- or 5-axis CNC machining when your parts involve complex geometries, intricate details, or require high precision. These technologies allow machining from multiple angles in a single setup, making them ideal for components that cannot be produced efficiently with standard 3-axis machines.
Industries such as aerospace, medical, and automotive often rely on 5-axis machining due to the tight tolerances and sophisticated shapes required. It’s also the preferred choice when you need shorter lead times, improved surface finishes, and maximum accuracy—without compromising on design.
CNC machining costs depend on several factors, including the chosen material, machining complexity, labor, tooling, and surface finishing requirements. For an accurate and fast estimate, feel free to request a quick quote.
