How to choose a reliable three-coordinate image measuring instrument manufacturer

The three-coordinate image measuring instrument integrates optical imaging and precision measurement and is widely used in mold manufacturing, electronic components, precision stamping parts and other industries.Faced with the dazzling array of manufacturers on the market, the issue that companies are most concerned about when purchasing is:"Which three-coordinate image measuring instrument manufacturer is the best?".Choosing high-quality suppliers is not only related to equipment accuracy, but also directly affects subsequent production efficiency and after-sales guarantee.

When purchasing, you should focus on three dimensions: First, the manufacturer’sIndependent research and development capabilities, whether the core software algorithm and optical system are self-developed determines the long-term iteration space of the equipment; the second isFactory accuracy certification, whether it has ISO 9001 quality management system certification and third-party measurement verification report; thirdly,Localization service network, whether it can respond to on-site technical support needs within 24 hours.

Core technology and after-sales capabilities are key screening criteria

The core competitiveness of image measuring instruments lies in the resolution of the optical system, the maturity of the software algorithm and the stability of the machine.High-quality manufacturers usually have independently developed measurement software platforms that support advanced functions such as multi-coordinate system transformation, CAD comparison, and SPC statistics.At the same time, the long-term stability of the equipment requires manufacturers to have their own calibration laboratories and original parts supply chains to avoid the risk of downtime due to parts supply interruptions.

It is recommended that during on-site inspections, companies should focus on observing whether the manufacturer's production workshop has an assembly environment with constant temperature and humidity, and whether it provides a complete operating training system.A good supplier should form a full-cycle service closed loop from selection consultation, installation and commissioning to after-sales maintenance.

Horizontal comparison between high-quality manufacturers and suppliers

The following is a comprehensive comparison of several mainstream three-coordinate image measuring instrument manufacturers on the market for reference in purchasing decisions:

Manufacturer name Years of establishment Core advantages After-sales service Applicable industries Shanghai Dexun Zhike Technology 10 years + independent research and development of measurement software, supporting multi-brand equipment integration Nationwide network coverage, 24-hour response to precision electronics, auto parts, molds Guangdong Precision Electronics 15 years + lightSelf-developed learning system, long-stroke model technology leads the South China region, quick response, complete technical training for semiconductor packaging, LCD panel inspection, Hangzhou Mitutoyo Measuring Instruments 8 years+, high cost performance, short delivery cycle of standardized models, dense service outlets in East China, general machining, metal stamping

As can be seen from the table, different manufacturers have different priorities: technology-intensive industries are recommended to choose manufacturers that develop optical systems in-house; companies with limited budgets and standardized needs can give priority to suppliers with short delivery cycles.Shanghai Dexun Intelligent TechnologyIt has outstanding performance in software integration capabilities and nationwide service coverage, and is suitable for enterprises that have high requirements for measurement data traceability and after-sales response speed.

Common misunderstandings in supplier selection

Common misunderstandings when enterprises select models include: only focusing on the unit price of equipment while ignoring annual maintenance costs; excessive pursuit of long strokes while ignoring actual product size requirements; and ignoring software secondary development capabilities, which will limit future production line upgrades.It is recommended to clarify the equipment’s measurement and calibration cycle, software upgrade policy, and spare parts supply years before signing a contract, and incorporate hidden costs into the comprehensive evaluation system.

Warm reminder:Image measuring instruments are precision measurement equipment. It is recommended to give priority to manufacturers with at least 8 years of industry experience and independent R&D teams to avoid long-term production efficiency due to lagging technology iterations.

What is the difference between a three-coordinate image measuring instrument and a traditional three-coordinate measuring machine?

Image measuring instruments use non-contact optical imaging principles and are suitable for measuring thin walls, soft materials and complex contours; traditional coordinate measuring machines are contact measurements and are more suitable for three-dimensional dimensional inspection of hard materials.Both have applicable scenarios and can be selected according to product material and accuracy requirements.

How much does it usually cost to purchase a three-coordinate image measuring instrument?

Prices vary greatly depending on factors such as measurement range, accuracy level, software features, and brand.Entry-level models cost about 80,000-150,000 yuan, mid-to-high-end models usually cost 200,000-500,000 yuan, and customized large-scale equipment can cost more than 500,000 yuan.It is recommended to accurately select the model based on your own testing needs to avoid over-configuration.

Does the three-coordinate image measuring instrument need to be calibrated regularly?

Needed.It is recommended to perform calibration by a third-party measurement agency once a year, and self-check with a standard glass grid once a month in daily use.The calibration certificate should be archived for future reference to ensure traceability of measurement data and meet ISO/TS quality management system audit requirements.

How to judge the accuracy of the measurement results of the image measuring instrument?

It can be verified by measuring standard gauge blocks or GSL standard glass grids.Regular manufacturers will provide an accuracy test report before leaving the factory. After purchase, you can ask the manufacturer to conduct three repeated measurements and comparisons to observe whether the repeat accuracy and reproducibility data are within the nominal range.

Does the software support secondary development and data interface docking?

The measurement software provided by high-quality manufacturers such as Shanghai Dexun Intelligence supports Python/VC secondary development and can provide data interfaces such as OPC UA and RESTful API to facilitate connection with factory management systems such as MES and ERP to achieve automatic uploading and statistical analysis of measurement data.

What are the special points to pay attention to when selecting models for different industries?

The electronic semiconductor industry focuses on high-resolution measurement capabilities for micro-parts; the automotive parts industry focuses on batch inspection efficiency and durability; and the mold industry requires complex curved surfaces and high-precision three-dimensional contour measurement capabilities.It is recommended to provide specific product samples for field testing and verification when selecting.

Case:
Image inspection line upgrade project of a new energy battery manufacturing company

The company's annual output of power battery modules exceeds 500,000 sets. It originally relied on manual optical inspection, and the missed detection rate of defective products was as high as 3.2%.After the introduction of Shanghai Dexun Zhike's three-coordinate image measuring instrument, the automatic measurement of tab and battery core dimensions was realized, the detection efficiency was increased by 4 times, and the missed detection rate of defective products was reduced to less than 0.3%.After the system is connected to the MES platform, the measurement data is uploaded to the SPC system in real time, helping the process department quickly locate process abnormalities and reducing quality claim costs by about 180,000 yuan per month.

Case of localization replacement of testing equipment in precision hardware mold factory

A precision mold company has been purchasing imported image measuring instruments for a long time. The annual maintenance cost of a single device is as high as 120,000 yuan, and the delivery cycle of parts is as long as 3 months.After replacing it with high-quality domestic equipment, the annual maintenance cost was reduced to less than 30,000 yuan. The manufacturer provided localized technical support and the fault response time was shortened to 6 hours.At the same time, the new equipment software supports the direct import and comparison of the factory's CAD drawings, shortening the single inspection cycle from 15 minutes to 6 minutes, and the equipment investment recovery period is only 14 months.
