OMM | Vision Measuring Machine: Total Solution for Precision Mold Measurement

Why Precision Mold Making Needs an Advanced Measurement Solution?

As the "mother machine" of industrial production, the dimensional accuracy of precision mechanical molds directly determines the quality of end products. In the era of micron-level manufacturing, traditional contact measuring tools (such as calipers and micrometers) struggle to meet the inspection requirements of complex mold cavities, micro-electrodes, and high-gloss surfaces.

Sinowon (SIG) has developed a high-precision Vision Measuring Machine specifically for the precision mechanical mold industry. Integrating advanced optical imaging and digital image processing technology, this Video Measuring System provides a non-contact solution for mold design, machining, and quality acceptance.

What Can One OMM Measure? – Full-Coverage Mold Inspection Capabilities

The Sinowon OMM meets the measurement requirements of the following mold elements:

1. Core Mold Components

• Mold Cavities & Cores: Precisely captures cavity depth, core contours, and minor deviations to ensure mold clamping accuracy.
• Micro-Electrodes & Thin-Walled Parts: Specialized optical solutions handle high-reflection scenarios, avoiding contact deformation of thin-walled parts.
• Mold Cutting Edges & Complex Surfaces: Motorized zoom lens with intelligent scanning algorithm enables high-precision contour acquisition.

2. Key Geometric & Dimensional Tolerance Measurement

• Flatness & Warpage: With an optional laser sensor, quickly scans multiple points on mold plates and outputs 3D color deviation maps to assist in identifying deformation risks.
• Perpendicularity & Position Tolerance: Ensures precise positioning of ejector pins, cooling channels, and guide holes for smooth slider movement.
• Straightness & Parallelism: Verifies the accuracy of linear sliders or guide rails on elongated molds.

3. Micro-Structures & Hole Measurement

• Micro-Holes & Slot Widths: Measures features from millimeter down to micron level, solving the problem of "can't see, can't measure" with traditional tools.
• Thread Parameters (Major Dia., Minor Dia., Pitch): Built-in algorithms automatically evaluate thread dimensions to improve inspection efficiency.

Key Problems Solved by the Vision Measuring System

Problem 1: Surface Scratching & Deformation of Molds

Solution: Non-Contact Measurement
No physical contact with the mold surface effectively reduces the impact of contact stress, properly protects high-gloss mirrors, unhardened soft molds, and thin-wall electrodes, avoiding secondary damage.

Problem 2: Low Efficiency on Complex Workpieces

Solution: Automated Batch Inspection
Replaces inefficient manual point-to-point methods. Equipped with a motorized zoom lens and CNC control, once programmed, the Video Measuring System can be recalled repeatedly. Single-part inspection time is significantly reduced, greatly improving first-article and in-process inspection efficiency.

Problem 3: Human Error & Non-Traceable Data

Solution: Digital SPC Reporting
Minimizes manual reading errors. The software automatically generates illustrated inspection reports. Data can be exported to MES systems for traceable quality data, providing solid support for process optimization.

Problem 4: Difficulty Imaging High-Reflection or Transparent Materials

Solution: Programmable 8-Zone Ring Light
Multi-angle programmable illumination enhances mold edge contrast, addressing edge-detection challenges on high-gloss metals and transparent plastic mold components.

How to Select the Right Model for Your Mold Shop?

Sinowon offers multiple OMM and Vision Measuring Machine models for different applications:

• Fully Automatic OMM: Ideal for batch inspection of precision molds. Auto-focus, auto-zoom, and auto-edge detection efficiently complete major dimensional measurements of mold cavities.
• Compound Flash Comparator: Suitable for high-volume inspection of fasteners and micro mold inserts. One flash captures multiple parameters within the field of view, ideal for screws, ejector pins, and micro inserts.
• Manual/Automatic Optical Comparator: For fast contour comparison of molds. Simple operation and high stability, suitable for quick shop-floor screening.
