In modern manufacturing, dimensional accuracy is not only a quality standard but also a core indicator of a company’s competitiveness. How to efficiently perform non-contact measurement of complex workpieces has become a key challenge in precision machining, mold manufacturing, and hardware component industries. With its excellent optical quality, precise coordinate system, and flexible human-machine interaction design, the precision profile projector is increasingly becoming an important quality inspection tool for many enterprises.

1. High-Quality Optical System Ensures Imaging and Accuracy
This series adopts a high-quality optical projection system. The core objective lens features multi-layer coating, offering excellent image clarity and chromatic aberration control. Whether it is edge contours, curves, small round holes, or chamfered bevels, the magnified image is clearly displayed on the projection screen, enabling operators to accurately read data.

The magnification options include 10×, 20×, 50×, and 100×, with errors controlled within an extremely small range and stable magnification accuracy. This means that even micro-structures—such as terminal hooks or subtle depressions on plastic housings—can be observed and measured without distortion caused by magnification deviation, greatly improving measurement reliability.

2. High-Precision Contour and Coordinate Measurement Capabilities
In industrial production, not only length and diameter but also the contour shape of workpieces require precise control. When measuring contours under transmitted illumination mode, this projector achieves an error of less than 0.08%, far outperforming conventional mechanical measurement methods. It is especially suitable for rapid inspection of stamped parts’ contours and complex tool shapes.

For coordinate measurement, the device uses a high-precision grating scale and fine adjustment mechanism, with indication error as low as (3 + L/200) μm, where L is the measured length in millimeters. For example, measuring a 50mm-long part yields an error of approximately 3.25μm, which is extremely valuable for high-end plastic parts and hardware clearance control.

3. User-Friendly Design for Convenient and Efficient Operation
To adapt to various onsite needs, the equipment is equipped with an optional dedicated micro printer and a footswitch. The printer outputs measurement data in real time, facilitating data traceability and report archiving during production; the footswitch frees the operator’s hands and improves efficiency, especially beneficial in repetitive multi-part measurements.

Additionally, the instrument supports free switching between erect and inverted images, allowing users to adjust the projection direction according to workpiece structure or reading habits. Combined with a high-contrast projection screen and fine-tuning knobs, even novice operators can quickly master its use.

4. Robust Structure with Strong Load Capacity
This series features a projector barrel lifting structure, unlike conventional small projectors that rely on stage vertical movement. The lifting mechanism is more stable and can support large or heavy workpieces (such as high-hardness mold parts or steel nuts) without compromising measurement accuracy. This is an irreplaceable advantage in many heavy-duty inspection scenarios.

For example, an auto parts company used this projector to inspect a thick-walled differential housing weighing 7 kg. Conventional projectors often suffer from stage sinking and image drifting under such weight, whereas this device maintained high-precision measurement performance, earning high praise from the client.

5. Wide Applications, Meeting Diverse Industry Inspection Needs
This equipment is widely used in hardware, stamping, plastic molds, terminals, screws, tools, electronic connectors, and other fields. Its advantage lies in high adaptability to complex-shaped, tiny-structured workpieces with strict tolerance requirements.

📌 Application Examples:

Stamped Parts Inspection: Checking metal sheet bending angles and punch positions, suitable for viewing edge lines with transmitted light;

Precision Plastic Molds: Measuring grooves, draft angles, and slots with high accuracy under magnification;

Tool Contours: Rapidly comparing complex shapes against CAD templates, focusing on symmetry and angle requirements;

Micro Terminals: Inspecting contact head bite widths and positional shifts, assisting electronic product quality control;

Screws/Nuts: Measuring head angles, pitch, and slot depth, crucial for automated assembly processes.

6. Conclusion: The Preferred Tool for Efficient Non-Contact Measurement
With ever-growing demands for high-precision and fast-paced measurement, traditional calipers, microscopes, and micrometers are increasingly unable to meet the complex requirements of modern workpieces. The precision profile projector, with its superior optical performance, high-precision measurement ability, and user-friendly operation experience, has become a powerful assistant for manufacturing enterprises aiming to elevate product quality control.

For companies pursuing reliability, efficiency, and precision, the profile projector is not just an inspection instrument but a robust guarantee of manufacturing process stability.
