Currently, many products on the consumer market have different requirements for air tightness testing. According to the appearance and performance of different products, the selection of air tightness detectors also differs.

First, let’s talk about several steps that need to be evaluated before choosing a leak tester:

1、When the companyWhen quality engineers are responsible for determining specifications, production processes, and testing procedures for new parts,Product manufacturerThe costs and benefits of leak testing should first be considered to determine whether testing the component is necessary.

2、If it is determined that leak testing is necessary for a manufactured component, the next step is to identify potential leak paths.Common areas include welds, seals, microcracks and pinholes.Most leaks are small and invisible to the naked eye, which is why precise, data-rich test results are needed.

3、After identifying potential leak paths, engineers establish leak rate rejection limits for the application based on theoretical calculations, industry specifications, and comparisons to specifications for similar existing applications.One of the most common methods of establishing rejection levels is to measure the leakage rate of customer-returned products.

4、Next, manufacturing engineers can work with engineers from the manufacturer that produces the air tightness tester,Determine the most appropriate leak testing method for the application,Whether it ispressure drop attenuation,Positive pressure test or negative pressure test or flow test method.According to the company’s budget,Product specifications required,Defined test methods and production integration requirements,productManufacturers can choose the leak testing instrument that best suits their needs.

5、bigMany times,productmanufacturers wantThe air tightness tester can be integrated with the production line. If this is the case, onceLeak tester selected, air tightness tester engineers can work withWork closely with customers and machine manufacturers to design individual fixtures to meet customer testing requirements.
