Material Testing Equipment

Popwil material testing machine is used to performing metallic or nonmetallic materials mechanical property test.
It is generally consists of a mainframe and necessary attachments, a servo controller and the data processing software, and a power unit. It is widely used in static test such as tensile, compression, bending, impact and hardness or dynamic test such as Crack Growth Rate, Fracture Toughness and other fatigue properties in normal or abnormal temperature conditions according to the standards of material test such as ASTM, ISO etc., in order to obtain the mechanical properties of the material.
According to its different loading method or power unit, Popwil material testing machine can be divided into hydraulic universal testing machine, hydraulic pressure testing machine and electronic universal testing machine etc. According to its usage, it can also be divided into impact testing machine, hardness tester, cement pressure testing machine, tensile testing machine and so on.

Additional attachments for rebar, stranded wire, bolt clamping, or clamping jaws with steps can also be provide according to request.
2. High precision load measuring device: by use of a precise hydraulic pressure sensor as the load sensor, the load measuring device can reach a wide range load measurement with high accuracy and no lateral force effect.
High precision piston stroke measuring device: by use of a photoelectric encoder as the displacement sensor, the machine can get 0.01mm piston stroke resolution
3. Movable lower cross beam:  crossbeam position can be adjusted by a motor and a worm and gear system.
4. Contract hydraulic power station: Integrated the hydraulic oil tank, the high pressure low noise gear pump with motor, the electric control panel and circuit, the Moog servo valve together into the station box in order to get the contracted construction and good performance. By use of load-adapting principle, the hydraulic power station can get quick response control result with very low power resumption and noise.
5. Output interface: a standard network interface. It can be used for data transmission and storage both inside LAN and on the internet.
6. Controller: a kind of built-in controller. Data acquisition card and I/O card are plugged inside a PC, and the application software which worked under the Windows, make ensure that the machine can doing the close-loop control of specimen deformation, piston displacement and load at the module of constant loading speed, constant piston stroke speed, constant strain speed control etc.  It can also doing the cycle test of load, piston stroke and sample strain. During the test, the control model can alternated smoothly.

WAW-G Series

1. Height adjustable chock block crossbeam positioning.
2. Semi-opened upper and lower jaw-blocks have best stiffness.
3. Plating columns are anti-rust. The pair of rotatable screw rods are the remarkable difference between the WAW- C Series and the WAW-D Series. The position of the lower crossbeam is adjustable by a motor which rotate the pair of screw rods.
4. High precision load measuring device: by use of a precise hydraulic pressure sensor as the load sensor, the load measuring device can reach a wide range load measurement with high accuracy and no lateral force effect.
High precision piston stroke measuring device: by use of a photoelectric encoder as the displacement sensor, the machine can get 0.01mm piston stroke resolution.
5. Gap sealed cylinder has a durable life.

2. WEW-D Series Computer Screen Displayed Hydraulic Universal Testing Machine

WEW Series Computer Screen Displayed Hydraulic Universal Testing Machine is a relatively simple testing machine used mainly in the area of metallic material’s mechanical capability testing. By adopt a loading frame, a manual controlled hydraulic power station, and a data acquisition and display computer, this kind of testing machine can perform tension, compression, bending or shearing test through a pair of hand-wheel-valve manual control hydraulic loading system according to the Chinese GB standard or ASTM, BS, JIS or DIN standard.

WEW-D Series

1. Load frame with auto clamping Jaws.
2. Hand-wheel operated hydraulic control valves.
3. Hydraulic power station with electric operation circuit and oil tank.
4. Displaying screen of the data acquisition computer.
5. Data acquisition and processing computer.

3. Computer Controlled Screw-driven Universal Testing Machine

WDW—Series computer controlled screw driven universal testing machine adopts a door type load frame. Through the gearbox, the tooth belt and the two pairs of screw and nut, the controller controlled the crossbeam up and down at a very large speed ratio. The clamping jaws or compress panels are connected to the crossbeam and the lower table plate, the specimen is tested at the space between the crossbeam and the working table. The advantages of this kind of testing machine are that at a very large loading speed ratio with very low noise and no hydraulic oil pollution, the machine can perform tensile, compress, bending and shearing tests for metallic materials. As the screw testing machine usually has a larger stroke than the hydraulic testing machine, it is more suitable for nonmetallic material test such as tearing test for plastic and puncture test for rubber etc. With the help of special attachments such as large deformation extensometer, climate chamber or high temperature oven, the testing machine can do special test under certain environmental condition.

WDW Series

1. The load frame: adopting door type loading structure. The moving crossbeam cut the door space into upper loading space and lower loading space. The load cell mounted together with upper clamping tool on the upper plate of the crossbeam. Usually, the lower place is used as the testing place.
2. Column cover: sleek aluminum cover with decorating colored rubber bar.
3. From servo motor to crossbeam: the final force loaded by the crossbeam on the specimen through the clamp jaws or compress plate. It comes from the AC Servo Motor who is driven by the computer controller. The moving of the Motor leads the movement of the crossbeam through a gearbox, tooth belts and ball screw assembly. These lead to smooth operation, high efficiency, low noise, long life, and no pollution.
4. Screen display and mouse operation: All test data and carve are displayed on the computer screen and all test operations despite Emergency Stop can be done by simply click the mouse.
5. Computer controller: built in computer controller can perform constant loading speed, constant displacement and strain speed control. Also, it can do cycle control with parameter like load, deformation or the displacement of the crossbeam. All control modes can be smoothly alternated.
6. The pedestal: mounted on the floor horizontally. The Servo Motor who drove the machine is installed inside this pedestal together with gearbox, the tooth belts and the amplifier who driven the motor.

WDW-D Series

There is only one different between WDW series and WDW-D series screw droved testing machine. The WDW series have only one testing space, which means that any kind of test, no matter tensile, compression, or bending, is finished in the same space between the working plate and crossbeam. The WDW-D series have double testing spaces, the upper testing space and the lower testing space. Usually the upper space is used to doing tensile test and the lower space is used to doing compression and bending test.

4. Computer-electro-hydraulic Servo Controlled Long Column Large Space Testing System

The long column large space testing system adopted four adjustable screw loading structure, large welded-steel plate made and floor-mounted working table, and a computer-electro-hydraulic servo controller. The tensile and compression actuator mounted on the adjustable crossbeam, and can be used to doing specimen test for the concrete and construction test such as tensile, compression and bending, for the real or ratio contracted pillar, beam or frame. The large and adjustable space leads to easy and quick installation of the structure or specimen. A very important advantage of this machine is that the specimen and the gage and connections lines fixed on the specimen are not move due to the upper installed actuator. This also ensures the reliability of data collection.

This kind of testing machine can be recognized as both material testing machine and structural testing machine.
