Product Evaluation

Evaluation of Endurance and Impact Characteristics of Plastic Products Using
Servopulser/Hydroshot Testing Machines
To ensure reliability and safety under actual usage conditions, it is essential to understand and control not only basic static Plastic Materials Evaluation of
strength, but also endurance (with respected to repeated stresses) and impact resistance characteristics. Servopulser fatigue
testing machines are able to efficiently apply precise repeated loads and reproduce various load waveforms experienced in actual
operation. Hydroshot high-speed impact testing machines can obtain failure characteristics data at speeds up to 20 m/sec.

Features of Servopulser
• Loading capacity and loading mode selectable based on a test object
The hydraulic configuration is able to repeatedly apply large loads (up to 300 kN for
standard models) at high speed, which allows fatigue testing of almost any material Raw Materials Evaluation of
or mechanical part.
• Stress and strain controls enable precision control
Closed loop servo control enables reproducing loading waveforms accurately
and faithfully. With fundamental cycle waveforms as well as random and actual
operating load waveforms, simulation testing can be supported as well.
• Select from two available controllers
Select either the compact 4830 controller or the 4890 controller, which allows
using various data analysis modes. Connected to a computer, these allow seamlessly Product Evaluation
performing all testing tasks via the computer, including configuring test parameter
settings, executing tests, and analyzing data.
• Extensive assortment of accessories
A wide assortment of accessories, such as test jigs (grips and so on), various external
sensors (to measure elongation and displacement), and environment control devices Tabletop Servopulser (Hydraulic)
(such as high/low temperature and high/low humidity), are available for configuring
an evaluation system that is optimized for given objectives.
• Electromagnetic and pneumatic systems are also available
For smaller loading capacity requirements, electromagnetic (Micro-Servo) and pneumatic Product Information
(Air-Servo) systems are also available as an alternative to hydraulic actuation. These models
offer lower environmental impact and are ideal for fields such as electronics.
• Also capable of multi-axis testing
Multiaxial systems (maximum 4 axes) can also be configured, which are ideal for
testing the endurance of actual parts, such as automobile components. Features
include an interaxial interference correction function based on transfer functions 4830 Controller and Operation Computer
and a resonant frequency tracking function.

Features of Hydroshot
• Hydraulic actuation enables accurate speed control
Hydroshot testing machines feature accurate flowrate control of pressurized hydraulic oil
and enable high capacities (maximum 10 kN) and high loading speeds (maximum 20 m/sec).
• Two types available – puncture or tension
The product line includes two types, the HITS-P10 model for puncture testing and
the HITS-T10 for tensile testing.
• Accurate measurements
A test force detector (load cell) designed to minimize reflection of vibration and stress
waveforms during high-speed loading and a crosshead displacement detector ensure
accurate data acquisition. A non-contact type chuck displacement gauge (for tensile testing)
is effective in measuring the amount of deformation in the area closest to the specimen.
• Extensive assortment of accessories
An extensive line of accessories are available to configure the optimal system, such as
various light-weight grips best-suited to the given specimen, approach jigs for tensile testing,
and thermostatic chambers to control the temperature of the testing atmosphere.
• Specialized operating software
All machines include software designed specifically for operating Hydroshot
machines. This ensures that all operations, from setting test parameters to organizing Hydroshot HITS-T10 High-Speed Impact
data can be performed as simply and safely as possible. (Tensile) Testing Machine
