In recent years, with the increase in the demand for sealing testing market, it is difficult for traditional sealing testing equipment to meet the production capacity requirements. Sealing testing equipment manufacturers have begun to launch sealing testing solutions that can meet various types. Single-channel, multi-channel, and multi-station sealing testing have become the development direction of the sealing testing market. When put into use in production lines, they have been welcomed by many customers.

Let’s first analyze the current mainstream marketSealing testerDetection principle:

1. The most advanced detection method currently on the market is pressure drop detection. This method can fill the sealed workpiece with a certain pressure of gas, maintain the pressure for a period of time (2 to 5 seconds), detect whether the pressure drops, and observe and calculate the pressure change to determine whether the product is leaking (the whole process is 5 to 25 seconds).

2. The sealing tester of this method has strong adaptability to supporting tooling and molds, and can be applied to semi-sealed products and fully sealed products.You can also pump air into a negative pressure inside a semi-sealed workpiece to detect leaks in the product (products that require external sealing can completely simulate the direction of water entering the product).The pressure drop method has high efficiency, strong versatility, high detection rate and non-destructive testing.Among them, the multi-channel sealing tester can detect multiple products at the same time, which is the current mainstream sealing tester testing method.

Multi-channel tightness detector trend analysis:

1. The domestic market for sealing testing in the past few years is not yet mature. Many companies do not have a special understanding of sealing testing methods. When purchasing sealing testing equipment, they are still testing the waters, so they prefer single-station sealing testing equipment. After a period of trial, it not only improves production efficiency, but also increases profits for the company, which also plays a role in promoting the sealing testing industry.

2. In a highly competitive market, innovating gradually and not being surpassed is a rule that most companies follow.Multi-channel sealing testing, one sealing tester testing two products at the same time or one sealing tester testing multiple products at the same time, has become an inevitable trend.

3. For manufacturers engaged in the sealing testing industry, after several years of experience in the sealing testing industry and the promotion of market demand for sealing testing, the sealing testing industry has overcome testing difficulties one by one. The emergence of multi-channel sealing testing instruments is also an inevitable trend.

Advantages of using a multi-channel tightness tester

1. Save time and cost; this detector can provide multiple detection channels during detection, and can detect three camera lenses at the same time. The test speed is three times faster than usual, which is more conducive to saving time and cost.

2. The equipment cost is lower; the multi-channel sealing tester controls the multi-channel sealing test by three testing equipment, and only needs one person to operate it, which streamlines the manpower for the enterprise and optimizes the manufacturer's capital chain.

3. Strong operability and high efficiency; the tester is also equipped with“Positive, negative”Two pressure forms and 8 basic test modes, which can be selected individually or combined.It uses 24-bit A/D conversion, 32-bit CPU operation, and a completely independently developed industrial control operating system, combined with a full-touch human-computer interaction interface.Built-in RS232 serial port, RJ45 network port, USB communication interface, LTP external I/O control port, supports multiple communication protocols, diversified self-service operations, and combines artificial intelligence with intelligence to enhance the operability of the device.
