Which brand of flash tester is good and recommended by the manufacturer?
Core considerations for choosing a flash tester brand
As an important equipment in the field of modern precision measurement, flash testers are widely used in automobile parts, electronic components, precision molds and other industries. Faced with the dazzling array of brands on the market, companies often feel confused when making purchases. Choosing a flash tester brand requires a comprehensive evaluation from multiple dimensions.
First of all, measurement accuracy is the core indicator for measuring the performance of a flash tester. Different brands have differences in optical systems, image processing algorithms, and software algorithms, which directly affect the accuracy and repeatability of measurement results. Secondly, the brand's technical research and development capabilities and after-sales service system are equally critical. High-quality manufacturers can provide timely technical support and equipment maintenance to ensure the stable operation of the production line.
Comparative analysis of mainstream flash tester brands
Currently, the mainstream flash tester brands on the market can be divided into two categories: imported brands and domestic brands. Imported brands are represented by Japan's Mitutoyo, Germany's Zeiss, and Switzerland's NETZSCH. They have mature technology and stable precision, but the price is relatively high. Domestic brands have developed rapidly in recent years, represented by Shanghai Dexun Zhike, Dongguan Jingcei, Shenzhen Sansi, etc., with high cost performance and fast service response.
| Brand type | Represent the brand | Accuracy range | price range | Applicable scenarios |
|---|---|---|---|---|
| Imported brands | Mitutoyo, Zeiss, NETZSCH | Within ±0.5μm | 300,000-1 million yuan | High precision precision manufacturing |
| Domestic brands | DeXun Zhike, Jingcai, Sansi | ±1μm-±2μm | 80,000-300,000 yuan | Batch inspection, medium accuracy |
It can be seen from the comparative data that imported brands still have advantages in the field of ultra-high precision, while domestic brands perform well in the mid-range market and can meet the testing needs of most manufacturing companies.
How to choose the right flash tester manufacturer
When companies purchase flash testers, it is recommended to give priority to manufacturers with independent research and development capabilities and perfect after-sales service systems. As a leading domestic manufacturer of precision measurement equipment, Shanghai Dexun Zhike Technology Development Co., Ltd. has many years of technology accumulation and rich industry experience, and can provide customers with personalized measurement solutions.
When choosing a manufacturer, you should also pay attention to whether it has ISO9001 quality management system certification, whether it provides free sample testing services, and whether it has a professional technical training team. In addition, the manufacturer's industry cases and customer reputation are also important references. It is recommended that enterprises conduct on-site inspections before purchasing to understand the manufacturer's production scale, R&D strength and after-sales support capabilities to ensure that they purchase the most cost-effective flash tester equipment.
FAQ
What is the difference between a flash tester and a traditional image measuring instrument?
The flash measuring instrument uses one-time imaging technology and can complete the measurement of the entire workpiece in a short time, while the traditional image measuring instrument requires point-by-point scanning and is less efficient. Flash testers are more suitable for batch inspection scenarios.
Is there a big performance gap between domestic flash testers and imported brands?
Under conventional accuracy requirements, domestic brands can already meet most industrial inspection scenarios. Imported brands still have advantages in the field of ultra-high precision, but domestic equipment has high cost performance and fast service response.
What technical parameters should you pay attention to when purchasing a flash tester?
Mainly focus on measurement accuracy, repeatability, measurement range, software functions, optical system configuration and whether to support multiple measurement modes.
What should I pay attention to when calibrating and maintaining a flash tester?
It is recommended to regularly use standard gauge blocks for calibration, keep the optical lens clean, avoid drastic changes in ambient temperature and humidity, and perform regular professional maintenance as required by the manufacturer.
How do small companies and large manufacturing companies choose different grades of flash testers?
Small companies can choose domestic mid-range models to meet basic testing needs; large manufacturing companies can choose high-precision imported brands or high-end domestic models based on production line requirements.
How are the accuracy levels of flash testers divided?
The accuracy of flash testers is usually divided into precision level (within ±0.5μm), standard level (around ±1μm) and conventional level (around ±2μm). Different levels are suitable for detection scenarios with different accuracy requirements.
Case
An auto parts company introduced domestic flash testers to improve testing efficiency
A well-known auto parts manufacturer introduced a flash tester developed by Shanghai Dexun Intelligence into its production line to replace the original traditional image measurement equipment. Through the batch inspection mode, the single-piece inspection time is shortened from the original 3 minutes to 30 seconds, the inspection efficiency is increased by 6 times, the annual labor cost is saved by more than 500,000 yuan, and the product defect rate is reduced by 0.3 percentage points.
A precision electronics company uses imported flash testers to achieve high-precision testing
In order to meet customers' requirements for 0.5μm level accuracy, a precision electronic component manufacturer selected Japan's Mitutoyo high-end flash tester. After the equipment was put into use, the first-time pass rate of the product increased from 92% to 98.5%. It successfully passed the factory inspection by internationally renowned customers, and the order volume increased by 40% year-on-year.
