Q&A: How to do hermeticity test and burst test for cylindrical lithium batteries? A clear article

This article introduces the two core tests of cylindrical lithium battery: air tightness test and burst test. The airtightness test accurately detects whether the battery seal is leaking through minimally invasive drilling, professional fixture system, pressure application and monitoring, etc. The burst test monitors the pressure resistance limit and rupture mode of the shell by slowly and uniformly increasing the pressure. With the advantages of integrated airtightness + bursting, one machine with multiple molds, high pressure capability, and accurate and stable results, Precision Tech's solution is suitable for the R&D and mass production of automotive-grade and power storage batteries.

How much kPa is measured by IP protection level and how to set the parameters of the air tightness tester?

This paper introduces the method of setting airtightness test parameters for IP66 to IP69 protection classes, including test pressure, instrument recommendation, test duration, etc. It also describes the method of defining test parameters and the four phases of establishing enterprise IP airtightness test standards, emphasizing that parameter settings need to be based on data-based decision-making and continuous optimization.

Quick Q&A: How does airtightness testing really work? How to define airtightness testing standards

This article introduces the principle of airtightness testing, steps, standard definitions and methods to ensure stable and reliable results. Airtightness testing is through the application of positive or negative pressure to monitor the pressure change to determine the sealing performance, divided into positive pressure method, negative pressure method and other ways, the process includes product positioning, inflation, pressure stabilization, testing and judgment. The development of standards requires comprehensive consideration of various factors. Precision Engineering can provide standardized and customized services for different enterprises, from experimental verification, jig design to mass production line data system integration.

Airtightness is the basis for products to realize waterproof and dustproof performance, while IP protection level and ATM waterproof level are important standards to measure sealing performance.

Sealability Testing: Concepts, Methods and Equipment Selection Guide

This article provides a comprehensive analysis of seal testing, covering related concepts, common methods and equipment selection. Sealability testing is crucial for many products to prevent gas or liquid leakage and to ensure normal operation and service life of the products. The paper introduces the concepts of sealing and leakage, describes the testing methods such as water immersion method and pressure decay method, and recommends equipment such as airtightness tester and true water tester.

Quick question and answer: What are the two types of equipment that are resistant to vandalism and whether or not the product leaks the working medium, respectively?

The article introduces two methods for testing the safety and reliability of industrial equipment: strength test and hermeticity test. The strength test uses a bursting tester to assess the equipment's resistance to damage and pressure-bearing performance; the hermeticity test uses a differential pressure hermeticity tester, which is highly accurate and fast, and can effectively assess the equipment's hermeticity performance. The article also mentions the customized solutions and successful cases of Precision Engineering's airtightness team, demonstrating its technical advantages and application achievements in the industry.

Popularization: product sealing leakage test rating standards and methods for details

This paper describes the rating criteria and methods for product leakage tests for sealing. Leakage is the migration process of gas molecules driven by differential pressure, and the leakage rate is the measurement index. Test rating needs to consider the leakage medium, leakage rate, test pressure and time and other factors. Commonly used methods include immersion method, pressure decay method, differential pressure comparison method and tracer gas method.
