Measurement inspection is an important part of molded product quality assurance.
The Aska Company emphasizes the quantification and control of various forces in addition to the external appearance such as length and depth. We have refined our original measuring instruments and technology to make it possible to measure values such as push, pull, and bending.
We provide contract measurement services based on these instruments and technologies.
Currently, we are accepting the following measurements. (Click below to open the measurement details.)
+ Uniaxial Strength Test 【Z-Gauge】
Uniaxial Strength Test [Z-Gauge]
Changes in applied force, such as pushing and pulling, are quantified.
It quantifies the "change in force" the rise of "push" and "pull" applied to the object by the movement of one axis.
It can quantify the peak value and the changes in force from the beginning to the end of the evaluation.
Since we can set the moving position and speed freely, irregular repetitive measurement is also possible.
Enabling numerical control of "sensory evaluation" and "repetitive testing," which have been difficult to evaluate until now.
The Z-Gauge, produced by the Aska Company, can perform a variety of measurements,
including repetitive strength tests and process tests up to fracture, by elevating and lowering the device on a single vertical axis.
Example: Cap fitting strength, film peeling strength, material tensile strength, material breaking strength, endurance strength, and other strength measurements.
High-precision control allows fine control of mechanical cylinder position, speed, and measurement accuracy.
We also propose fixturing jigs as needed.
All forces from start to end of measurement can be output numerically.
For example, it is possible to measure the moment when the pen barrel and cap are mated over the undercut. It is also possible to measure the entire process of how the undercut is loaded and finally mated.
In this measurement, we found that the stress before the maximum value is related to the sensuality of closing the cap.
Quantification of Sensory Evaluation
Auto-Quantifying the force applied for sensory evaluation, which is difficult to evaluate.
Proposing Measurement Method and Fixture
We also offer a variety of measurement methods and fixtures necessary for evaluation by the customer's requirements.
Repeated evaluation by automatic operation eliminates operator error.
If you're having trouble with these things, this is for you!
・Measurements are taken using force gauges, but there are variations when measuring depending on the operator. ・It takes too many hours for inspectors to measure, including repetitive compression and tensile tests. ・I want to know if the numerical variation during research and development is correct.
①Designing a jig that fits the individual workpiece to be measured, and fixing the workpiece in place.
②Setting the speed, movement, number of repetitions, and other settings that suit the measurement.
③Obtaining the strength values of the digital force gauge in a time series, and submitting the CSV data as documentation.
PLC controls measurement speed, travel distance, and travel speed. We can set them freely and finely.
If you have any measurement requests, please let us know.
We will propose a strength measurement that meets your needs.
Examples of utilization to date
First time opening strength measurement of the paper pack.
Measurement of variation in peeling performance of the sealing area.
Measurement of the suppleness of the clip part of the pen's lid.
Measurement of strength variation when we open and close the lid.
We suggest measurement by Standard Machine (TYPEⅠ) or High Precision Machine (TYPEⅡ) according to the evaluation.

High Precision Machine
+ Biaxial Strength Test 【XZ-Gauge】
Biaxial Strength Test [XZ-Gauge]
Complex force changes are quantified by freely moving the two axes.
The biaxial strength test can reproduce various conditions by using two axes in the X-axis and Z-axis directions.
The test reproduces the movement of a human hand or a machine in two axes and measures the "change in force."
By simultaneously manipulating two axes in the X-axis and Z-axis directions, XG-Gauge mechanically reproduces the force, which is difficult to do with a single axis.
Complicated motion settings are possible, such as reproducing complex movements of a human arm or hand. We can also set the force of a complex machine.
Repeated measurements are also possible if you repeat the same motion mechanically.
The applied force is measured and can be output as a CSV file.
・Measurement of force applied to the hinge
・Repeated opening and closing of the cap
・Measuring the amount of powder discharged
The force can be measured and quantified in a variety of ways.
Reproduces human motion and enables measurement in a form close to actual use
It controls the X-axis (horizontal movement) and Z-axis (vertical movement) at the same time to reproduce complex human hand-like moves.
It can quantify the values applied during such moves from the start to the end of the measurement.
Various measurements such as repetitive motion by automatic operation and irregular motion such as high speed and low speed can be performed.
It is possible to manage sensory values such as "good" and "this feeling," which were previously impossible to quantify, as concrete values.
Please tell us the measurement points
Please tell us even if you do not know how to measure.
If you specify the measurement point, we can propose a measurement method, design the jig, and take care of everything else.
If you have a measurement method you have been using, we would be happy to make suggestions accordingly.
Aska Company's technological capabilities allow us to propose the most appropriate measurement method.
Wide measurement range
PLC (commonly known as a sequencer) controls the motion of the two axes. We can set any desired motion and speed (acceleration/deceleration.)
We can perform tensile strength test, compression strength test, fracture strength test, mating strength test, repeated endurance strength test, etc.
※It is possible to measure the specific movement "force" that we couldn't measure in the uniaxial direction.
Example of measurement contents
By operating in two axes and creating a jig for measurement, we can measure various objects.
Tensile strength test
Compressive strength test
Fracture strength test
Mating strength test
Repeated endurance strength test (automatic repeated operation under the same conditions is possible)
Due to the wide range of possible applications, we will be happy to suggest measurement methods.
Reproduces free movement with 2 axes
The equipment can reproduce human hand movements and other movements close to actual use, enabling evaluations closer to reality.
Proposed measurement method
We will make proposals starting from the measurement method. We also offer design services when using jigs.
※Only the measurement fee is charged for the second and subsequent measurements.
Wide range of applications
We offer a variety of measurement programs that utilize biaxial motion in addition to human motion.
This will solve what you're having trouble with now!
・The inspectors use force gauges for measurement, but the measurement values vary from person to person.
・The inspector's man-hours for measurement, such as repetitive pressure test, are too much.
・Are the current evaluation methods and measurements correct?
+ Impact Test Measurement【S-gauge】
Impact Test Measurement [S-Gauge]
Quantify Invisible Fracture Strength
Use fracture strength to compare ease of fracture.
What is 50% Impact Fracture Energy?
S-Gauge evaluates fracture strength using the value of 50% impact fracture energy (J: joule).
50% fracture energy is a method of determining the value that when we apply a specific value of fracture energy to a container, it will crack about 50%.
Under the same conditions, this value (J) can be used to compare the ease of fracture.
While there are physical property values for plastics at the raw material level, such as in Izod tests, this method is useful for product development and quality inspections because we can ecaluate the actual products.
Special jig for cup measurement
In this table, the falling energy of the weight is given to the object fixed by the jig. We raise the height when the judgment is "not destroyed" and lower when the result is "destroyed."
The table shows that the third and fourth times are the borderline between non-destructive and destructive, so the third and subsequent times are used in the calculation. The average of data from 10 or more times is usually the value of 50% impact fracture height.
How to find 50% impact fracture energy
◎The 50% impact fracture height is calculated by the following equation.
[Formula] 50% impact failure height (H50% cm) = height of reference point (cm) + travel width (5 cm) x (Σ(i.ni)/N± 1/2)
◎The 50% breakdown energy is obtained by the following equation.
[Formula] 50% fracture energy (J) = load (kg) x gravitational acceleration (9.8m/2s) x 50% impact fracture height H (cm)
Easy visualization of measurement data with analysis software
JIS uses the above calculations, too. However, since they are hard and complicated, you can use the Excel spreadsheet provided with S-gauge to obtain the 50% impact fracture height and 50% fracture energy by simply entering the load and ✓-X judgment.
