I. What is the product pressure resistance test?
Simply put, the product pressure test is a key part of examining how much "pressure" a product can withstand without succumbing. It is more than just evaluating a product's "pressure resistance", its deeper significance lies in the fact thatEnsure that the product can operate safely and stably within the pressure range it is designed to commit to.. The core objectives of this test arePreventing ruptures, leaks or other forms of damage that may result from pressure overrunsThis builds a solid safety defense for the user and guarantees the long-term reliability and service life of the product.
Second, the application of voltage withstand test: throughout the key areas, guarding the lifeblood of operation
Because of its decisive role in safety and reliability, the application scenario of pressure resistance testing is very wide, covering almost all products and systems that need to carry or resist pressure:
- Pressure vessel field:For example, industrial gas storage tanks, civilian liquefied petroleum gas tanks, etc., the pressure resistance test is the "gatekeeper" to ensure storage safety and prevent catastrophic accidents.
- Piping system engineering:Whether it's the energy arteries that carry oil and gas or the water supply networks that safeguard everyday life, pressure testing ensures that pipelines are stable under constant pressure.
- Critical valve components:From industrial process control valves to precision valves in automotive engines and pipelines, pressure testing ensures that they open and close accurately under pressure to control fluids.
- Automotive core components:Engine block, brake system piping, fuel system, etc., each of which needs to pass a rigorous pressure resistance test to provide basic protection for driving safety.
- New energy batteries:In the booming field of new energy vehicles and energy storage, the structural strength and pressure resistance of the battery casing are directly related to the safety and efficiency of the entire battery system.
- Common Electronics:Even the housings of devices such as cell phones and tablets that we come into contact with on a daily basis need to have a certain level of pressure resistance to cope with unforeseen situations in use.
Third, industry standards: standardize the testing process to ensure that the results are authoritative
Pressure withstand testing is far from discretionary; it requires strict adherence to recognized industry standards, such asInternationally recognized ISO series standards, American ASTM standards and Chinese GB national standards, etc.. These standards thenTest conditions, specific methods, pressure parameters and qualification criteriaAll of them have made detailed provisions. Compliance with these standards is a prerequisite to ensure that the testing process is scientifically rigorous, the test results are accurate and reliable, and provide an authoritative basis for product quality assessment.
Fourth, Precision Engineering pull burst tester how to test the battery shell?
With the rapid development of new energy vehicles and energy storage technology, the market demand for battery safety has reached an unprecedented level.The strength and pressure resistance of the battery casing (also known as the aluminum casing of the battery cells), as the key structural component that holds and protects the cells, is the lifeline that determines the safety of the battery pack. Once the battery case fails under pressure, the consequences can be unimaginable.

In this context.JCGK is an independent research and development, design and production of thePulling and bursting test machine(also known asBursting Pressure Tester,Pressure loading test machine)(math.) genusSpecialized tools designed to meet the demands of such demanding testsTheIt works by accurately controlling and gradually applying pressure to the product under test, such as the battery case in this example, until the product ruptures, or reaches a pre-set maximum pressure/deformation limit.

Through this process, the ultimate pressure capacity and safety margin of the product can be accurately assessed.
In the case of battery case pressure testing, Precision Engineering's testing machines are able to simulate the various pressure challenges that batteries may endure in actual working conditions:
- Internal Pressure Simulation: e.g. gas pressure inside the battery due to chemical reactions, thermal runaway or drastic temperature changes.
- External Pressure Simulation:: External forces such as crushing, collision, etc. to which the battery may be subjected during transportation, installation or use.
Typical battery case voltage test procedure:
- Sample Preparation: Select clean and dry battery case samples that meet the test requirements.
- Precision Clamping: Securely mounted on the tester using specialized fixtures designed for specific battery cases.
- parameterization: On the intelligent control system of the testing machine, set the target pressure, pressurization rate, holding time and other key parameters required for the test.
- startup test: After confirming that there is no error, start the tester and the equipment will apply pressure automatically and smoothly according to the preset program.
- Real-time data logging: During the testing process, the tester's high-precision sensors will monitor and record key data such as the pressure change curve and the amount of shell deformation in real time.
- Analysis and determination of results: At the end of the test, based on the detailed data recorded, judge whether the battery case samples meet the pressure resistance performance index against the relevant standards or technical requirements.

The core advantage of the Precision Engineering Bursting Pressure Tester:
- High Precision Control and MeasurementThe accuracy of the applied pressure and the reliability of the measurement results are guaranteed, providing high-confidence data for R&D and quality control.
- Efficient Testing Process: Optimized pressurization logic and fast data acquisition system to significantly reduce single test cycle time.
- All-round safety and security: Built-in over-voltage protection, safety door lock interlocking, emergency shutdown and other multiple safety mechanisms to ensure the safety of operators and equipment.
- User-friendly operation interface: Intuitive and friendly user interface and easy operation process, lowering the threshold of use.
- Flexible customization capabilitiesCustomized test procedures, pressure ranges and fixtures are available to meet the specific testing needs of different customers.
