Zipper Reciprocating Tester FY-II
Zipper Reciprocating Tester is used to determine the product life of metal or plastic zipper under condition of specified load of specified times of stretching cycle. This machine is used for zipper in a strength process of lateral and longitudinal, it could be test its bearing ability in reciprocating motion for a regulation time.
Zipper Reciprocating Tester FY-I Description
Zipper Reciprocating Tester is used for zipper in a strength process of lateral and longitudinal, it could be test its bearing ability in reciprocating motion for a regulation time. When test, this tester lead the puller of zipper in an equal-speed to do the reciprocating motion for certain number of times of per min & least until regulated times up.
Follows are Zipper Reciprocating Tester specification :
- Counter of stretching cycle settable freely, and record the test cycles automatically;
- Automatically stop with buzzing to remind;
- High definition digital display;
Application of Zipper Reciprocating Tester
Zipper Reciprocating Tester is is used for zipper in a strength process of lateral and longitudinal,
Test items is as belows :
(1) tensile strength test in parallel.
The tensile strength is the most basic strength, which is very similar to the actual state of using and testing the ability of the zipper teeth to resist the transverse forces in the interlock state.
(2) upper strength testing.
Zipper teeth interlock and will head to the upper seam allowance, holding her head and can be measured on the upper strength of zipper, This is to simulate the zipper to resist external force ability during
(3) down strength testing .
Pull the head to the lower end of the zipper, and the teeth are divided into the left and right sides. The chain teeth on the left and right sides
Which can be measured the force strength to stop the damage, of course can measure the resistance of the internal components of the pull head.
