The precision of Plastic CNC Milling often surpasses that of injection molding. CNC Milling typically offers exceptional precision, often with tolerances in the range of 0.001 inches, making it suitable for producing highly accurate and intricate plastic parts. In contrast, while injection molding is efficient for high-volume production, its tolerances may be slightly lower due to factors such as tool wear. Therefore, if precision is a top priority for your plastic parts, CNC Milling is a preferred choice over injection molding.
