Overview of domestic image profile measuring instrument industry

As the core equipment in the field of precision measurement, image profile measuring instruments are widely used in automobile manufacturing, aerospace, electronic semiconductors, mold processing and other industries. In recent years, with the rapid breakthroughs in domestic precision manufacturing technology, domestic image profile measuring instrument brands have made significant progress in terms of accuracy, stability and cost performance, gradually breaking the monopoly of imported brands and becoming an important supporting force for the transformation and upgrading of the manufacturing industry.

The image profile measuring instrument uses optical imaging and image processing technology to achieve non-contact, high-precision measurement of geometric parameters such as the two-dimensional contour, size, angle, etc. of the workpiece. Compared with traditional contact measurement methods, this technology has the advantages of high efficiency, no damage, and can measure complex contours. It is especially suitable for the inspection needs of thin-walled parts, soft materials, and precision micro parts.

Inventory of the top ten brands of domestic image profile measuring instruments

Based on a multi-dimensional comprehensive assessment of market share, technical strength, user reputation and industry influence, the following are representative brands in the field of domestic image profile measuring instruments:

Brand selection and purchasing advice

When enterprises purchase image profile measuring instruments, they should focus on the four core elements of measurement accuracy, repeatability, software functions and after-sales service. Domestic equipment has strong competitiveness in scenarios with conventional accuracy requirements (within ±2μm), and is significantly better than imported brands in terms of response speed, customized development, and price advantages.

It is recommended that users give priority to brand suppliers with industry application cases, complete technical training and after-sales support based on their own product characteristics, production capacity needs and budget range to ensure long-term stable operation of the equipment.

FAQ

What is the difference between an image profile measuring instrument and a two-dimensional measuring instrument?

The image profile measuring instrument has more comprehensive functions, supporting functions such as automatic recognition of complex contours, angle measurement, and CAD comparison, while traditional two-dimensional measuring instruments mainly focus on basic dimensional measurement.

Case

A new energy vehicle battery tray testing project

Shanghai Dexun Intelligent Technology provided an image contour measurement solution to a new energy vehicle company to conduct full-size contour inspection of the aluminum alloy shell of the battery tray. The equipment uses high-precision optical lenses and a self-developed AI recognition algorithm to shorten the inspection time of a single piece to less than 3 minutes. The measurement accuracy is stable at ±1.5μm, helping customers increase quality inspection efficiency by 40% and reducing the missed detection rate of defective products to less than 0.02%.

Aeroengine blade profile detection application

An aviation manufacturing company introduced a domestic image profile measuring instrument to inspect engine blade profiles, replacing the original imported equipment. The equipment is equipped with a high-precision telecentric optical system and professional measurement software to achieve comprehensive measurement of blade profile, angle and size. The measurement results are more than 98% consistent with the three-coordinate inspection results. The equipment purchase cost is reduced by approximately 35%, significantly improving inspection efficiency and reducing operating costs.
