Can We Maintain Pressure Consistency Without High-Accuracy Gas Measurement?
No, it is not possible to maintain pressure consistency without high-accuracy gas measurement. When gas weight accuracy is combined with high speed, even the slightest deviation affects the product’s performance and reliability. Insufficient gas leads to the product not being fully dispensed or resulting in poor spray quality; conversely, excessive gas can cause high internal pressure in the can, jeopardizing safety standards. Therefore, absolute precision is essential for consistent pressure and a safe product.
How Are the “Acceptable Tolerance Limits” Determined in Industry Standards?
When determining the acceptable tolerance limit for gas filling, product performance and safety requirements are taken as the basis. For example, environmental and operational variables such as air temperature, machine speed, and operator factor are important factors that affect the tolerance limits of gas and liquid filling. These variables are the determining factors of the filling precision’s tolerance range.
What Are the Key Factors Determining the Precision of the Control Mechanism?
The overall precision of the safety control mechanism depends not only on sensor technology but also on many factors, including the general operational conditions of the factory. Factors such as process stability and machine calibration directly affect the repeatability of the filling process. In addition to these primary weight control systems, leak control mechanisms are also used for quality assurance. For example, a leak detection device or the traditional water bath test is critically important for verifying post-filling product safety and integrity.
What Procedure Is Followed When Cans Exceed the Acceptable Tolerance Limits?
When cans exceed the tolerance limits determined by the industrial weight controlstandard, a strict rejection procedure is initiated. The weighing station immediately flags the can that falls outside the acceptable limits (under-filled or over-filled), and the control system isolates the faulty can from the main production line using a high-speed rejection mechanism before it moves to the next stage.
