2. Non-technical personnel are not allowed to disassemble and repair this machine. If disassembly and repair are required, the operation shall be carried out under the condition of ensuring power off and accompanied by personnel for supervision to avoid accidents.

3. When opening or closing the door or taking or putting the test object out of the test chamber, do not let the test object contact with the rubber edge of the door or the edge of the box to prevent the rubber edge from being worn.

4, the surrounding ground should be kept clean at any time, so as not to suck a lot of dust into the unit to deteriorate working conditions and reduce performance.

5. Attention should be paid to protection during use, and it should not be collided with sharp or blunt objects. The test products placed in the laboratory should be kept at a certain distance from the suction and exhaust air outlets of the air conditioning channel to avoid hindering the air circulation.

6. Prolonged inactivity can reduce the system's effective lifespan, so it should be powered on and operated at least once every 10 days. Avoid frequent short-term use of the system. After each operation, the system should not be restarted more than 5 times per hour, with each start-stop interval being at least 3 minutes. Do not open the door when it is cold to prevent damage to the door seal.

7. After each test, set the temperature near the ambient temperature, work for about 30 minutes, then cut off the power supply, and wipe clean the inner wall of the working room.

8. Regular cleaning of the evaporator (dehumidifier): Due to the different cleanliness levels of the samples, a lot of dust and other small particles will be condensed on the evaporator (dehumidifier) under the action of forced air circulation, so it should be cleaned regularly.

9. The condenser should be maintained regularly and kept clean. Dust sticking to the condenser will make the compressor dissipate heat poorly, resulting in high pressure switch jumping and generating false alarm. The condenser should be maintained regularly.

10. Regularly clean the humidifier to prevent scale buildup, which can reduce its efficiency and lifespan and cause blockages in the water supply lines. To clean it, remove the evaporator panel from the working chamber, use a soft brush to scrub the humidifier, rinse with clean water, and drain promptly. 11. Regularly check the test cloth of the wet bulb. If the surface becomes dirty or hard, replace it to ensure the accuracy of the humidity sensor's readings. The test cloth should be replaced every three months. When replacing it, first clean the water collection head, wipe the temperature sensor clean with a clean cloth, and then replace the test cloth. Ensure your hands are clean when replacing the new test cloth.

Introduction

Reliability testing is a critical process in the development and production of equipment, ensuring that devices meet specified performance standards under expected operating conditions. Depending on the test environment, reliability testing can be classified into laboratory testing and field testing. Laboratory reliability tests are conducted under controlled conditions, which may or may not simulate real-world scenarios, whereas field reliability tests are performed in actual operational environments.

 

Based on the objectives and stages of product development, reliability testing can be further divided into:

• Reliability Engineering Tests (including Environmental Stress Screening (ESS) and Reliability Growth Testing) – aimed at identifying and eliminating faults, typically conducted during the development phase.
• Reliability Statistical Tests (including Reliability Verification Tests and Reliability Measurement Tests) – used to validate whether a product meets reliability requirements or to estimate its reliability metrics, usually performed during development and production.

 

This article focuses on Reliability Statistical Testing, covering test procedures, methodologies, performance monitoring, fault handling, and reliability metric calculations.

Historically, switching bag specifications required hours of recalibration. Modern modular machines use standardized components (adjustable folding systems, intelligent alignment devices) for rapid changeovers. Operators select preset parameters via touchscreen interfaces, enabling automatic adjustments for dimensions and single-side bottom sealing. This flexibility supports small-batch custom orders, helping manufacturers capture high-value markets.

 

3. Digital Production Management: From "Human Expertise" to "Data-Driven"

Legacy machines depend on skilled technicians for setup, leading to downtime and inefficiencies. Digital systems enable lean production through:

Cloud-Based Process Libraries: Store heat-seal parameters (temperature, pressure, speed) for different bag types (e.g., valve bags, open-mouth bags), reducing changeover time from 2 hours to 20 minutes.

Real-Time OEE Monitoring: Track Overall Equipment Effectiveness (e.g., downtime causes: roll changes, seal bar maintenance) to optimize production cycles.

 

4. Green Technology: From Energy Guzzler to Low-Carbon Leader

Valve bag production has long been energy-intensive, but next-gen solutions deliver sustainability:

Servo Motors: Replace traditional drives, cutting energy use and noise.

 

Eco-Conscious Design: Helps manufacturers reduce carbon footprints while maintaining output.

 

Conclusion:

The evolution of valve bag-making machines reflects broader trends in packaging: smarter, more adaptable, and sustainable production. For heavy-duty industries, these advancements mean lower costs and stronger competitiveness. Investing in next-gen equipment isn’t just about efficiency—it’s a strategic move to future-proof operations. Have you embraced these changes? Share your insights below!
