Overview
MFY-01A automatic sealing tester is a product of CHENCHI brand, which is suitable for sealing test of Encasement bags, bottles, tubes, cans, boxes, etc. in food, medical apparatus, daily chemical, automobile, electronic components, stationery and other industries.
Features
1. Microcomputer control, test parameters can be set, and the test process is automated.
2. The LCD screen displays the test process, and parameters such as setting pressure, setting pressure holding time and real-time pressure are displayed simultaneously.
3. PVC operation panel, new button layout, simple and convenient operation.
4. The sealing barrel material is made of good organic Glass pipe, and the wall thickness reaches the highest 15mm Film thickness in the industry.
5. The pressure holding time, test pressure, and supplementary pressure ratio can be set in advance to achieve one-click operation of the test process.
6. Precision pneumatic components, superior sealing performance, more reliable mass.
7. Automatic constant pressure air replenishment according to the supplementary pressure ratio during the test, without manual operation.
8. At the end of the test, the pressure will be automatically blown back to unload, saving more operating time.
9. Comes with compressed air filtrating and pressure regulating device, the external device is convenient to drain water and clean impurities, effectively ensuring the safe operation of the internal components of the machine.
10. In order to ensure the normal and interference-free operation of the instrument, the instrument adopts the three-power independent power supply mode. The host controller has an independent power supply, the pressure receiving module has an independent power supply, and the pressure control module has an independent power supply.
11. Good pressure sensor, with precision fast relay to make the supplementary pressure response faster, and the pressure does not overshoot, always maintained at the set pressure. Built-in pressure calibrating module and support multi-point pressure calibrating, convenient three-way calibrating inspection.
Principle
By vacuuming the vacuum chamber, the sample immersed in water to produce internal and external pressure difference, the test sample internal gas escape outside the case, in order to determine the sealing performance of the sample; by vacuuming the vacuum chamber, the sample to produce internal and external pressure difference, the test sample expansion and release of vacuum after the sample shape recovery, in order to determine the sealing performance of the sample.
Applications
Food Industry: Soft Bag Encasement, Semi-hard Encasement, Hard Encasement; Medical Apparatus Industry: Closed Container, Blister Encasement, Small Headspace Encasement; Miscellaneous Industry: Tyvek, All kinds of Aluminum Foil Bags, Wet Tissue, Cosmetics Encasement, etc
Standards
GB/T 15171、ASTM D3078
Steps
1. Set parameters such as pressure holding time, test pressure, and supplementary pressure ratio.
2. Put the sample into the sealing bucket.
3. Start the instrument and automate the vacuuming and testing process.
4. Observe the gas escape or shape change of the sample.
5. At the end of the test, the automatic back-blowing unloading pressure.
Notice
• Make sure the air source pressure is 0.7Mpa before use, and the air source needs to be provided by the user.
• Regularly clean the compressed air filtrate and pressure regulating device to prevent impurities from affecting the operation.
• The instrument is powered independently by three power sources to ensure that the power supply is connected correctly.
• There is no need to manually operate the air replenishment during the test process, and the instrument automatically replenishes the air at constant pressure.
• Automatically unload the pressure after the test to avoid manual intervention.
