High-Precision Measuring Tools in Plastic Mold Processing
High-precision measuring tools are crucial in plastic mold processing to ensure dimensional accuracy, shape tolerances, and assembly precision.
1. Coordinate Measuring Machine (CMM)
Features:
Performs precise three-dimensional measurements using a probe that can contact the workpiece or operate non-contact (laser or optical).
Highly automated, suitable for complex structures and high-precision measurement requirements.
Applications:
Measures geometric dimensions, shape tolerances (e.g., flatness, roundness, straightness), and positional tolerances (e.g., coaxiality, perpendicularity).
Ideal for inspecting complex curved molds, such as those used for automotive and household plastic parts.
2. Laser Interferometer
Features:
Measures length and displacement based on laser wave interference principles.
Offers extremely high resolution and precision, commonly used for equipment calibration or reference measurements.
Applications:
Evaluates the linear motion precision of mold processing equipment.
Calibrates machine tools or measures critical mold dimensions.
3. Video Measuring Machine (VMM)
Features:
Utilizes optical systems and image processing technology for non-contact measurements.
Capable of magnifying and capturing minute features of workpieces, enabling high-precision 2D and 3D dimension detection.
Applications:
Measures the shape and positional tolerances of small and complex mold components.
Ideal for non-contact measurement of thin-walled parts and micro features.
4. Profile Measuring Instrument
Features:
Accurately measures the contour curves of mold surfaces.
High resolution allows for detailed surface analysis.
Applications:
Inspects the shapes of curved mold surfaces (e.g., cavities and cores).
Used for shape error analysis of complex parts in mold processing.
5. Surface Roughness Tester
Features:
Measures surface roughness parameters of molds (e.g., Ra, Rz).
Available in handheld and tabletop models, easy to operate.
Applications:
Evaluates mold surface finish, especially for molds where high-quality surface requirements are critical for injection-molded products.
