Injection Mold Surface Finishes
Discover surface finishing to eliminate cutting and welding marks, enhancing both functionality, aesthetics for superior-quality parts.
As Machined
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.
Painting
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.
Plating
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.
Polishing
A mechanical finishing process that smooths and buffs the surface to achieve a reflective, glossy appearance. Reduces surface roughness and improves overall aesthetics.

Injection Molding Quality Control
Mold and Pre-produdction Inspection
Proper mold design and pre-production checks are key to injection molding quality. Engineers consider part geometry, material flow, and cooling systems to guarantee smooth production. Trial molds are tested to confirm all functions work correctly, providing stable and consistent results.
In Process Quality Control
Continuous checks during production keep custom molded parts consistent. Injection machine parameters such as speed, pressure, and temperature are monitored within set limits. Regular inspections of part dimensions and appearance help detect and fix issues quickly.
Final Inspection
Completed parts undergo thorough final inspection to meet design and quality standards. Teams check dimensions, appearance, and physical properties. Precision instruments like coordinate measuring machines (CMM) and colorimeters verify that all components meet strict standards.
Injection Molding FAQs
When Should I Choose 4/5-Axis CNC Machining?
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.
What Is the Maximum Part Size for 4/5-Axis CNC Machining?
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.
When Should I Choose 4/5-Axis CNC Machining?
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.
How Much Does CNC Machining Cost?
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.
