What is a glass bottle internal pressure resistance tester?

Glass bottles are important packaging materials widely used in many industries, including food, cosmetics, and chemical products. Due to their excellent sealing performance and protective properties, glass bottles are extensively applied for packaging various products. However, if glass bottles burst due to excessive internal pressure during filling, sterilization, transportation, or storage, it may not only result in product loss but also cause potential safety accidents.Therefore, to ensure the quality and safety of glass bottles, internal pressure resistance testing is of great importance. By evaluating the pressure-bearing capacity and safety margin of glass bottles, manufacturers can effectively identify potential risks, optimize production processes, and ensure reliable performance throughout the product lifecycle.

Structure and Working Principle of Glass Bottle Internal Pressure Resistance Testing Machine

The Glass Bottle Internal Pressure Resistance Testing Machine mainly consists of the following components: pressure pump, pressure sensor, control unit, and safety protection device. The pressure pump is used to generate high-pressure liquid; the pressure sensor is responsible for measuring pressure changes inside the glass bottle; the control unit controls the entire testing process and processes test data; while the safety protection device ensures operational safety during testing.

The working principle is mainly based on placing the glass bottle to be tested inside the testing machine and then injecting high-pressure liquid into the bottle through the pressure pump. Meanwhile, the pressure sensor continuously monitors the internal pressure changes of the bottle in real time. The control unit evaluates whether the glass bottle meets the required standards by comparing the preset pressure value with the actual measured pressure value.

If the glass bottle does not rupture or show any abnormal phenomena within the specified test duration, it indicates that the bottle has good internal pressure resistance performance and can safely withstand pressure variations during filling, sterilization, transportation, and storage processes.

Application Scenarios: Covering Full-Life-Cycle Quality Control

1. Quality Control During Production

During the manufacturing process of ampoules, internal pressure resistance testing can quickly identify defective products with uneven wall thickness, excessive internal stress, or annealing process defects. For example, after introducing the testing machine, a company discovered that a batch of ampoules ruptured at only 0.45 MPa. Further investigation traced the issue back to temperature control deviations in the annealing furnace. After process adjustments were implemented, the product qualification rate increased from 92% to 99.5%.

2. Sterilization Process Verification

High-pressure steam sterilization is a commonly used process for ampoule packaging, requiring the container to maintain structural integrity under conditions of 121°C and 0.2 MPa. The testing machine can simulate sterilization pressure conditions to verify the compatibility between ampoules and sterilization equipment. A vaccine manufacturer discovered through testing that the pressure resistance value of a certain ampoule model decreased by 15% after sterilization, leading to optimization of the glass formulation and successfully resolving packaging failure issues.

3. Transportation Environment Simulation

During transportation, ampoules may experience vibration, stacking pressure, and atmospheric pressure variations. The testing machine can be combined with constant-pressure holding tests to evaluate the impact resistance of packaging materials. A logistics company demonstrated through testing that after adopting cushioning materials, the breakage rate of ampoules was reduced from 3.2% to 0.5%, significantly improving transportation safety and packaging reliability.
