Glass Four-point Bending Tester
This tester is applicable to analysis and research of static
physical performance test on phone glass,tablet computer
glass,liquid crystal glass,touch sensor glass,toughened glass with
three-point,four-point bending and elongation test;can do
experiments according to International standard like GB,DIN,ISO,JIS
and ASTM as well as furnish information(like JC/T676-1997glass
material bending test methods,BS EN 1288-3-2000 architectural glass
and determination of glass bending strength);test data is in form
of dynamic curve display;it automatically obtain maximum
force,maximum deformation,bending strain,bending strength,bending
modulus,,compression strength,compression force,etc.
1. Host:Table type dual-space structure ;horizontal Lifting adopts
continuously variable transmission;replacement of upright post,
lead screw and outer cover can change test space;transmission
system consists of exclusive reducer controlled by server,arc
timing belt and ball screw,which has stable operation,high
efficiency,low noise and no pollution.
2. Accessory:a set of single point,three-point and four-point
compression attachment;exclusive accessory for lens,which is manual
operation with easy and reliable holding,no slipping and movement
1. Built-in controller achieve closed-loop control of crossbeam
2. Imported AC server motor with stable and reliable properties is
equipped with over current,over pressure,over speed and over load
protection devices.speed regulation ratio can be 1:100000
3. Electrical control line is in conformity with international and
national standards and has strong Anti-interference ability.
4. automatic shift:shift to appropriate measurement range according
to load,which achieve physical zero adjustment,gain setting and
of testing force measurement.
5. conditional saving.make control data and sample condition a
module,which is very convenient to batch test.
6. Multi control mode:single step program control and multi step’s.
7. PID control algorithm adjust loading process with constant-speed
control ≤5% and pressure maintaining control≤0.5%;provide
professional user with control program editor,in which way user can
flexibly customize control program based on actual situation.
8. Automatic speed change:During test,speed of moving crossbeam
automatically change as preset program,which also can be changed
9. Automatic calibration:automatically achieve calibration of
10. Automatic Saving:automatically save test datas and curves
11. Process:test process,measurement,display and analysis are
completed by microcomputer.
12. Batch test:for sample with same parameters,do it in order after
13. Test software:Chinese WINDOWS interface with menu prompt and
14. Display mode:data and curve are dynamically displayed during
15. Curve ergodic:re-analyze the curve and use mouse to find
corresponding test data at any point
16. Curve option:choose
curve to display and print.
17. Test report:compile a report and print it as customer’s
required format;it has a network interface for transmission and
saving of data,record printing and network transfer printing as
well as linking to Intranet and Internet
18. Limit Protection:programmable limit protection and mechanical
19. Automatic shutdown:when sample breaks,moving crossbeam will
20. Overload protection:If the load exceed 3-5% of each gear’s
maximum,it will automatically stop.
