Explanation of the advantages and disadvantages of several common drop testers

1. Arm drop tester

Introduction: The dual-arm drop tester is mainly used to assess the degree of impact of the package during the actual transportation, loading and unloading process, and to assess the rationality of the impact strength and package design of the package during handling.

 

Advantages: This machine can perform free drop test on the surface, corners, and edges of the package, equipped with a digital display height display and a decoder for height tracking, which can accurately give the product drop height, and the error of the preset drop height Not more than 2% or 10mm . This machine adopts single-arm double-column structure, with electric reset, electronically controlled drop and electric lifting device, easy to use ; unique hydraulic buffer device greatly improves the service life, stability and safety of the machine. The single arm setting can easily place the product, and the angle error between the falling impact surface and the bottom plane is less than or equal to 5 degrees.

 

Disadvantages: Each time the test is completed, the drop arm must be dropped ; after the new machine is installed in the factory, it is necessary to add a suitable low concentration oil at the sliding round rod. If the oil has a long time and there is too much dust, please lower the machine to a low level. Ministry, wipe the oil before the test, and then heavy machine oil ; drop the impact of mechanical equipment, the new machine is used more than 500 times, the screws must be tightened in order to avoid failure ; test machine lift Shafts and chains need to be regularly lubricated. The gear box is changed once every six months ; all power should be cut off during non-operation to ensure the lifting shaft is clean.

 

2. Single arm drop tester

Introduction: This tester is designed to simulate and test various products in the process of handling or transportation, and it will be evaluated when the products are damaged during the process of transportation or transportation, so as to obtain the best solution so that they can try their best Reduce the loss ; This tester can test the packaging container of the diamond, angle, surface.

 

Advantages: The single-wing drop tester places the product to be tested ; a certain placement method is selected: surface, edge, and corner to make it fixed ; digital display height can be freely set according to user's security. Any height ; after a good height is determined, the solenoid valve is lost and the test piece leaves the arm freely and falls freely. Press the "stop button" to automatically reset the drop board.

 

Disadvantages: Single-wing drop tester drops electronic product packaging ; plastic product packaging falls ; toy product packaging falls ; Other finished product packaging drop, etc.

 

3. Zero drop testing machine

Introduction: The zero drop tester is mainly used to assess the degree of impact of the package during the actual transportation, loading and unloading process, and to assess the rationality of the impact strength and package design of the package during handling. The zero drop tester is mainly used for drop test on larger packages.

 

Advantages: The zero drop tester consists of an “ E ” type fork that can be quickly moved downwards as a specimen holder. The tested goods are placed in balance according to the test requirements ( face, edge, angle test ) . During the test, the pallets moved downwards at a high speed, and they were separated from the test pieces. The “ E ”-shaped fork was embedded in the bottom plate under the action of a high-efficiency shock absorber before the tested packaged goods fell to the bottom plate. Theoretically, the E -shaped fork was theoretically dropped. The tester can make a drop test from zero height to the maximum drop height range. The drop height is digitally set by the test request and the drop test is performed automatically at the set height

 

Disadvantages: For large-scale packaged goods, the general quality is relatively large, and the vertical drop height during transportation and transportation is relatively low. Therefore, the drop height of the drop test rig is also required to be lower. The zero drop tester is mainly used for larger packages. Drop test. The zero drop tester consists of an “ E ” type fork that can be moved down quickly as the specimen holder. The tested goods are placed in balance according to the test requirements ( face, edge, and angle tests ) . During the test, the pallets moved downwards at a high speed, and they were separated from the test pieces. The “ E ”-shaped fork was embedded in the bottom plate under the action of a high-efficiency shock absorber before the tested packaged goods fell to the bottom plate. Theoretically, the E -shaped fork was theoretically dropped. The tester can make a drop test from zero height to the maximum drop height range.
