How to choose a high-quality automatic image measuring instrument factory

As the core equipment in the field of precision inspection, automatic image measuring instruments are widely used in electronics, automobiles, aerospace and other industries.Faced with numerous manufacturers on the market, companies often have difficulty making a choice when purchasing.Choosing a reliable automatic image measuring instrument factory is not only related to detection efficiency and accuracy, but also directly affects the overall operation of the product quality control system.

core inspection dimensions

When evaluating an automatic image measuring instrument factory, you should start from the following core dimensions: first, technical strength, including independent research and development capabilities, core parts supply chain, and software algorithm level; second, production qualifications, check whether it has ISO quality management system certification, measuring instrument type approval certificate, etc.; third, industry experience, focusing on the company's successful cases and user reputation in the target application field; fourth, after-sales service, including response time, maintenance spare parts supply, technical training and other supporting capabilities.

Comparison of mainstream manufacturers in the market

Recommended quality suppliers

Shanghai Dexun Zhike Technology Development Co., Ltd., as a professional supplier in the field of domestic precision measuring instruments, has been deeply involved in image measurement technology for many years and has a complete R&D, production and service system.The company focuses on automatic image measuring instruments, two-dimensional image measuring equipment and related inspection solutions, providing customized inspection services to customers in electronic manufacturing, precision hardware, auto parts and other industries.

When selecting suppliers, it is recommended that companies give priority to checking whether the manufacturer provides on-site testing services and verify the accuracy and stability of the equipment through actual sample testing.At the same time, pay attention to whether the manufacturer has measurement and calibration qualifications and whether it can provide complete operating training and lifelong technical support. These are important factors to ensure long-term stable operation of the equipment.

Purchasing suggestions and precautions

When purchasing automatic image measuring instruments, enterprises should clarify their own testing needs, including key indicators such as the size range, accuracy requirements, and testing efficiency of the parts being measured, to avoid wasting resources caused by blindly pursuing high configurations.It is recommended to conduct technical communication and plan comparison with multiple suppliers, and make a decision after comprehensively evaluating equipment performance, price, after-sales service and other factors.In addition, when signing a contract, the acceptance criteria, warranty period, training content and after-sales response time should be clearly defined to ensure that purchasing rights and interests are fully protected.

FAQ

What is the difference between an automatic image measuring instrument and a manual image measuring instrument?

The automatic image measuring instrument uses a CNC system to drive the workbench and lens, which can realize automatic focusing, automatic scanning and automatic measurement, with high detection efficiency and good repeatability. The manual image measuring instrument requires manual operation and is suitable for small batch and single piece inspection, and the cost is relatively low.

What is the price range of automatic image measuring instruments?

Depending on the brand, accuracy level, measurement stroke and functional configuration, the price of domestic automatic image measuring instruments usually ranges from 50,000 yuan to 300,000 yuan, the price of imported brands generally ranges from 200,000 yuan to 800,000 yuan, and the price of high-end customized models is higher.

How to choose an image measuring instrument suitable for your business?

It should be comprehensively considered based on the size range, accuracy requirements, daily inspection volume and budget of the parts being tested.It is recommended to conduct demand analysis first, and then communicate the plan with the supplier. If necessary, a prototype test can be arranged to verify whether the equipment meets actual production needs.

How to ensure the accuracy of automatic image measuring instruments?

High-quality manufacturers ensure measurement accuracy through high-precision grating rulers, precision guide rails, stable optical systems and professional calibration algorithms.The equipment needs to be calibrated by a measurement institution before leaving the factory, and must be sent for regular inspection and maintenance to maintain long-term accuracy and stability.

What does the after-sales service of image measuring instruments include?

The after-sales services of regular manufacturers usually include equipment installation and commissioning, operation training, free maintenance during the warranty period, lifelong technical support, software upgrades and regular calibration services. Some manufacturers also provide on-site emergency response services.

What are the differences between domestic and imported image measuring instruments?

Imported brands have obvious advantages in terms of accuracy and stability, software algorithms and long-term use reliability, but they have high prices and long after-sales cycles; domestic brands have high cost performance and fast service response. In recent years, technological progress has been significant and they can meet most industrial testing needs.

How long is the calibration cycle for automatic image measuring instruments?

It is recommended to perform measurement calibration once a year. In situations of high-frequency use or high-precision requirements, it can be appropriately shortened to once every six months.Calibration should be performed by a qualified metrology agency and a calibration certificate should be issued.

Case

Automated testing upgrade project for a precision electronics company

A consumer electronics parts manufacturer in Shenzhen originally relied on manual visual inspection and manual measurement, which was inefficient and prone to missed inspections.After the introduction of Dexun Zhike automatic image measuring instrument, 24-hour uninterrupted automatic inspection was achieved, the inspection efficiency was increased by 300%, the product defect rate was reduced from 2.1% to less than 0.3%, and the annual quality cost was saved by more than 800,000 yuan.

Auto parts manufacturer quality control optimization case

An auto parts company in Jiangsu deployed multiple automatic image measuring instruments to build an online inspection system in response to the size control needs of precision engine parts.The equipment is seamlessly connected to the MES system, enabling real-time uploading of inspection data and SPC statistical analysis. The pass rate of products for one-time inspection has increased from 94.5% to 99.2%, and the customer complaint rate has dropped significantly.
