Assistive technology : Plastic anti-theft caps sealing

 Plastic anti-theft caps sealing and opening torque force test method described

Pressure on the HC drinks in plastic caps to protect against theft mainly polyolefins , the main raw material, through injection molding, Yahuo hot process other casting. Can according to different uses can be divided into soft drink bottle caps and non-carbonated beverages. Anti-theft plastic sheeting key role leaked to the content, but also the needs of consumers to easily open session of the lid. Therefore, anti-theft cap sealing performance and torque of energy are two of the most important points of quality control.

At present, the maximum local anti-theft Plastic appropriate standard GB/T17876-2010 (plastic packaging container theft caps), which contains a gas cap, gas cap sealing performance and torque strength, etc. clearly defined. Which states that the opening performance of torque: the smaller size of 38mm maximum torque strength must be 2.2Nm 0.6Nm, specifications less than 38mm and a height of no more than 12MM bottle torque 0.4Nm 2.2Nm power, 38MM maximum torque must be a force specifications 2.9Nm 0.6Nm. Application three feathers in stone, of Nellie -20 cap torque test to test, test before the numerical strength of the input tool settings specified torque, clamping the body is flat, and in turn hats, ie when the alarm when the value of the instrument power up a predetermined torque. Operating torque use the power of choice 1.2nm

In addition to sealing performance standards are clear:

First, the cover is flat (except for cover gas) with a limit of machine stressed the power of torque selected, with the test device sealing, pressure to 200kPa, pressure underwater medium 1min, and monitor whether the leakage, then increase the pressure on 350kPa, packaging medium 1min, take cover popup loose.

Second, the maximum carbonate (CAP gas) with a limit of machine tightens the torque of a specific energy, and reduce theft ring sealed pressure test meters to 690 KPA, the pressure underwater medium 1min, or pressure leakage to increase the pressure 1207kPa medium 1min, take cover popup loose. Three springs in the stone company that specializes in testing anti-theft cap sealing design and manufacture of MFY-06 intelligent device sealing, and the instrument off with a lid, and hats to protect against theft, test crawl, test snake, creep rupture seven types of pilot projects and meet chains worn 28MM, 30MM, 38MM anti-theft cap seal performance test equipment of plastic for the selection and installation of cover anti-theft on bottle and a bottle of torque Wenli test 20 of the setup torque in the test, and then install the appropriate size of the cap seal plastic stealing performance testing, and sealed in the tank transparent, through the tool of standard automatically injection pressure at the time of automatic packaging, which have been observed in this process OIC hat thick with or without bubbles set with or without a cover phenomenon.

 Is a standard feature not a qualifying product.
 
This method is suitable for mineral water bottles, liquor bottles, regular soda.
