The core value and purchasing significance of image measuring instruments

Video Measuring Machine is a precision measuring equipment based on optical imaging and digital image processing technology. It is widely used in manufacturing fields such as electronics, automobiles, molds, and aerospace.For bulk purchasing companies, choosing reliable wholesale brands and manufacturers not only directly affects measurement accuracy and production efficiency, but also affects long-term equipment maintenance costs and supply chain stability.

The core advantage of the image measuring instrument is non-contact measurement, which can quickly obtain the two-dimensional size, angle, position and other geometric parameters of the part. The measurement efficiency far exceeds that of traditional contact instruments.In mass production scenarios, stable equipment supply and complete after-sales support are the keys for companies to ensure product quality consistency.

Comparative analysis of mainstream brands

At present, image measuring instrument brands on the market can be divided into two camps: international first-line brands and domestic high-quality brands, each with its own emphasis:

Brand Origin Positioning Price Range Applicable Scenarios Mitutoyo Japan's high-end precision molds, semiconductors Nikon Japan's high-end precision aerospace, precision electronics Zeiss Germany's ultra-high-end extremely high-precision scientific research, automotive core components Serein China's mid-range cost-effective general industrial manufacturing, batch testing Hexagon Sweden's high-end integrated high-large components, multi-axis linkage measurementTips:International brands have obvious advantages in accuracy, stability and software ecology, but the procurement cycle and price are relatively high. Domestic brands have made significant technological progress in recent years and have outstanding cost performance in conventional industrial inspection scenarios.

Key Considerations for Wholesale Purchasing

When companies purchase image measuring instruments in bulk, they should comprehensively evaluate the following dimensions:

Brand qualifications and industry reputation:Give priority to brands with ISO certification and years of industry experience, and avoid purchasing OEM products without after-sales guarantee.Technical specifications match:Select equipment with appropriate range and resolution according to the size range and accuracy requirements of the parts being measured (such as 0.001mm level or 0.005mm level).After-sales service system:Image measuring instruments are precision equipment. It is necessary to confirm whether the manufacturer provides complete services such as calibration, maintenance, and training, and whether the response time meets production needs.Bulk price and payment terms:For wholesale purchases, you can strive for tiered quotations. It is recommended to compare more than 3 suppliers and comprehensively evaluate the unit price, delivery time and warranty terms.

Shanghai Dexun Zhike Technology Development Co., Ltd. has long been committed to the supply and service of precision measurement equipment. It can provide brand selection suggestions and batch purchasing plans based on the actual needs of enterprises, helping customers optimize testing costs and efficiency.

FAQ

What is the general minimum order quantity for wholesale purchasing of image measuring instruments?

Different manufacturers have different minimum order quantity requirements. Some brands support trial purchase of a single unit. Bulk purchases of more than 5 units usually enjoy tiered discounts. It is recommended to contact the manufacturer's sales consultant directly to confirm the specific policy.

Is there a big gap between domestic image measuring instruments and imported brands?

In the field of conventional industrial inspection, the accuracy and stability of domestic image measuring instruments can meet most needs, and the price advantage is obvious; however, for ultra-high-precision scenarios such as semiconductors and aerospace, imported brands still have technological leadership.

How are the accuracy levels of image measuring instruments divided?

Common accuracy levels are divided into 0.001mm (high-precision level), 0.002mm (standard level) and 0.005mm (economic level). When selecting, the corresponding accuracy level needs to be matched according to the part tolerance requirements.

How to judge the manufacturer's after-sales service capabilities when purchasing wholesale?

You can check whether the manufacturer has a local service team, provides regular calibration services, repair response time commitments, and spare parts supply guarantees. If necessary, you can ask to visit the customer sites you have cooperated with.

How long is the calibration cycle for image measuring instruments?

It is recommended to perform professional calibration every 6 to 12 months. For high-frequency use or key testing positions, it is recommended to shorten the time to 6 months to ensure the continued reliability of measurement data.

Can wholesale purchases customize equipment configurations?

Most manufacturers support customizing lens configurations, workbench dimensions, software function modules, etc. according to customer needs. Customization services are more flexible when purchasing in bulk, and you can communicate with the manufacturer's technical department in detail.

Case

Bulk purchasing case of a precision electronics company

A consumer electronics parts manufacturer in Shenzhen has an annual output of over 5 million pieces, but its original testing capacity was insufficient, resulting in shipment delays.The company purchased 6 Sirui VM series image measuring instruments in bulk through Kuehne + Nagel. After the equipment was put into use, the inspection efficiency increased by 40% and the annual inspection cost was reduced by approximately 28%. At the same time, it received free operation training and one-year warranty service from the manufacturer.

Auto parts supplier inspection and upgrade case

An auto parts company in Zhejiang replaced its original domestic equipment with three Japanese Mitutoyo image measuring instruments due to customer review requirements to improve testing accuracy.Dexun Intelligent Technology assisted in completing equipment selection, on-site installation and accuracy verification. The new equipment controlled the measurement repeatability error within 0.002mm and successfully passed the customer's quality system audit. Two additional units of the same model were subsequently purchased.
