Heat seal testers

The heat seal testers GHS-03, HST-H3, HSTH6, HTT-L1 and PSST-100 determine the optimal sealing parameters such as temperature, time and pressure for the different film materials.
The heat seal testers GHS-03 allows the simultaneous testing of 5 samples independently. The hot tack and seal property tester HTT-L1 can additionally measure the peel force, tension and shear force of tapes. The PSST-100 is a portable seal strength tester.

Shrink Tester
The models RSY-R2 and FST-02 are suitable for determining the heat shrinkage properties of films made of polyethylene, ethylenes and copolymers and mixtures thereof. The shrinkage, contraction force and the shrinkage ratio of shrink films under specified test conditions can be determined in this way. With RSY-R2 the films are tested in an oil bath without clamping in the apparatus. In the apparatus FST-02 up to 3 samples can be simultaneously and independently clamped and tested each other.

Leak Detectors
In the area of the leak tests, we offer three different leak testing devices: MFY-01, LSSD-01 and RGT-01.
Packaging materials with vulnerabilities as sealing seams or products are subjected to a pressure difference, are tested to their tightness qualities, failure and durability as well as creep characteristics and compression resistance. The devices can be used for a variety of packaging shapes. The model MFY-01 can test the tightness of seals of different packages through the differential pressure method in water and thus detect leakage and deformations in a vacuum.
The sealing quality of bottles, tubes, caps and other packaging is checked by the device LSSD-01. With the over pressure method, the creep and failure limit and the compression resistance can be measured quantitatively.

The device RGT-01 is the only product on the market, which can perform a quantitative analysis of the residual oxygen in vacuum packaging. The quantitative seal behavior of the packaging can be checked by the differential pressure method and the liquid analysis technique.

Adhesive and Tape Tester
The devices CZY-G and CZY-6S test the adhesion and adhesive properties of test samples as pressure-sensitive tape, plasters, adhesive labels and protective films. While the Model CZY-G works with the Rolling Ball method, six samples can be tested simultaneously under the influence weight with CZY-6S. This model is controlled by a microcomputer. Other testing equipment like peel adhesive tapes testers may to be found in the catalog of mechanical test instruments.

These and other test equipment will be shown at the FachPack 2015 in Nuremberg.

Tiedemann offers a huge portfolio of material testing instruments incl. systems for permeation test for a lot of different specimen like vapor, different gases incl. oxygen. All these products are manufactured by our partner Labthink, China. The products are wide spread in use with very good success and reliability.

Water Vapor Permeation
With our water vapor permeability testing equipment, the amount of water vapor can be measured which permeates through a layer of material. The specific ambient temperature and humidity can be set for each test. Depending on requirements, devices for flat packing materials or finished packages, as well as various sensors and measurement methods are available.

The premium device W3-330 and TSY-W3 are equipped with an electrolytic sensor. By a connection of W3-330 with nine satellite modules up to 30 different samples can be measured simultaneously. The TSY model is distinguished by its ease of use. Both devices have an integrated software and can both test finished packages as well as flat material samples.

In W3-130 the water vapor permeation is determined by a humidity sensor. From three samples both averages and individual measurement results are determined. The device W3-320 is equipped with infrared sensors in all the three chambers. In the models W3-030, W3-031, W3-060 and W3-0120 permeation is determined by weight measurement. The device W3-060 is equipped with six chambers and can test simultaneously by a network of satellites further modules up to 60 samples.
The model W3-0120 has 12 measuring chambers.

Gas Permeation
The equipment for measuring the gas permeability can be used for different materials and gases (air, O2, N2, CO2, CH4, H2, organic gases and mixtures). The specific ambient temperature and humidity is adjustable. Depending on requirements, devices for flat or finished, individually shaped packaging with different measurement methods are available.

By measuring the pressure difference, the models VAC-V1, VAC-V2, V3-VAC, VACVBS, G2-130, G2-131 and G2-132 can measure the transmission rate of gas, the solubility coefficient, the diffusion coefficient and the permeability rate for plastic sheets, laminated films, especially impermeable materials, tires, sheets, osmosis membranes and many other materials. The VAC devices are connected to a computer, while the G2 devices are equipped with an integrated software and only need input devices and a monitor.

For final packaging and containers such as bottles or packages, the device G2-130 is suitable. The model G2-110 is worldwide unique for checking the gas permeability of separation membranes.
If the material to be tested is a battery diaphragm, rubber sheet, laminated flat foil or polymer film we recommend the model BYTB2P.

With DM2-330 test are possible in addition to the differential pressure measurement, even with the constant pressure principle / the coulometric method, or a combination of both measuring methods. It is suitable for all of the above flat and non-flat materials.

For measuring the permeation of organic gases (eg, benzene, ethanol, aldehydes, ethers), we recommend the model OR2-410.
The MGT-01 is so far the only device in the world that can measure the gas permeation of mixed gases, while the TQD-G1 is designed specifically to measure the air permeability.

Oxygen Permeation
The oxygen Permeation tester OX2-230 and OX2-231 are equipped with a coulometric sensor and measure the oxygen barrier of the material sample after the constant pressure principle. Pastic foils, laminated, extruded, coated or high-barrier materials may also be tested as finished packages and containers made of plastic, rubber, paper or glass. The measurement can be carried out simultaneously in up to three independent chambers.

OX2-231 is our entry-level model and is characterized by a very high efficiency and cost-effectiveness. As the carrier gas, nitrogen is used. The high-performance device OX2-230 has a larger inspection range with higher accuracy. Here both nitrogen and nitrogen mixtures can be used as carrier gas.

This unit can be connected via a network with up to nine other satellite equipments. As a result, 30 different samples can be measured and controlled simultaneously.

Easy Made Surface Pressure Evaluation

The ability to measure surface pressures and pressure distributions with the unique Fuji pressure sensitive film has been available for more than 30 years. The measurement range covers surface pressures from 0.05 to 300 MPa.

The measurement method is quite simple: the films are placed between the components to be measured. After loading a red imprint of the image will appear on the film, where the colour intensity is a measure of the surface pressure.

Applications

The FujiFilm Prescale can be used almost in all sorts of measurements of surface pressure, or simply to show the pressure distribution. The films may be used both in air and in water. The tests usually have two different objectives: to check the uniformity of surface pressure or measure the pressure at dedicated points.

The following list provides only a preliminary overview of the versatility of the films and helps to identify similarities to specific measurements.

• Pressure distribution between pressed surfaces, valves, gears, pumps, hydraulic cylinders for the design of seals, gaskets or to verify the machine assembly
• Pressure distribution under heavy equipment and supports or the testy of tyre profiles
• Pressure contacts and pressure patterns on brakes, clutches, injection moulds, roll pressure or rollers in print machines
• Quality control of sealings like sterile packagings, blisters or bags and cartons in the food industry

Qualitative Evaluation

A qualitative overview of the pressure distribution is already given by inspection of the printed image. The areas with high intensity of red indicate a high surface pressure, while the areas that experienced little or no red colour indicate a lower pressure. For many applications, this qualitative statement is sufficient.

Quantitative Measurement

A quantification of the pressure from the printed images is possible at different levels of accuracy.

The user manual that accompanies each package of Fuji Prescale Film presents two different calibration curves for different types of load cycles – short load contact and continuous load. One is for a 5 seconds load cycle only, the other for constant pressure for 2 minutes. These are examples of applications for short-term and in long-term applications.

The different colours at continuous load and short-term exposure is due to the continuous rupture and to a small extent when the micro-capsules are at constant load, so that the same load at a longer period of action leads to a slightly darker result. Fuji guarantees an accuracy of about 10%.

Computerized Analysis of the Results

The Fuji-FDP-8010E software delivers a wide range of evaluation opportunities in conjunction with the scanner from EPSON.

For intensity measurement, the FUJI-print images have to be scanned. The setting of the flatbed scanner is made via a supplied calibration card to adjust the greyscale. In order to measure the scanned footprint with the different red intensities, the program relies on the given calibration curves per film, equal to the manual.

The measured values allow a digital, one-off or planar imaging computation. The program offers various possibilities, such as false colour or 3D representation of the surface pressure.

Using this Windows-based image-processing program, the applications for the FujiFilm Prescale have been significantly expanded.

Sigma-Nip, Digi-Nip and Auto-Nis for rollers alignment

The readjustment of rollers and their exact setting is of great importance in many industries. Whether in paper manufacture or processing, during lamination or printing processes high quality products are always ensured. In addition, minimizing the downtime is a strong target to save costs. To achieve high accuracy in a short time, we offer two different solutions. One is based on real time measurement of the nip width even during adjustment, the second is an approximation using Prescale pressure indication films and a scanner to measure nip and pressure distribution along the roller.

Nip-Width Analysis with Sigma-Nip in Real Time

The electronic nip analysis system measures and calculates the nip width at different points along the rolls in real-time. The system Sigma-Nip consists of a series of sensors that are placed between the rollers together with an analysis program. The sensors can be positioned quickly and easily. They survive high pressures and are able to measure simultaneously with high accuracy and reproducibility. It is the ideal solution for setting all kinds of rolls.

The nip width measurement system consists of various sensors, based on thin film resistance technology, which are positioned at specific points between the rollers. Once the sensors are placed, the rolls can be closed. The Windows based software shows simultaneously the nip widths in an easily interpretable way on the screen. The user thus immediately detects if the rollers are adjusted.

Since the analysis system operates in real time, the rollers can be adjusted directly in the closed state. Changes in the alignment can be directly monitored on screen. After proper adjustment the print out documents the final status. Sigma-Nip comes complete with all necessary system components for quick and accurate nip width determination. The system consists of 3 to 15 sensors depending on customer requirements, the sensor hub with USB cable, intuitive software and a standard notebook.

Sigma-Nip Sensors

The sensors are available in two different lengths to fit various diameters and roller covers. The standard sensor has a measuring length of 213 mm, while the mini-sensor covers a length of 84 mm. All sensors are calibrated individually.

Nip-Width Analysis with Digi-Nip for Smaller Rollers

Digi-Nip is the ideal instrument for shorter and smaller rollers. With minimal investment and without experience a user can quickly and accurately record the nip width – the contact length between rollers. With Digi-Nip nip readings can be determined instantaneously between 0.6 to 25 mm with an accuracy of 0.1 mm. Adjustments are made while the two sensors are between your rolls. Digi-Nip is designed to provide thousands of readings before sensor replacement is necessary. The weight of the portable system is 0.9 kg.

Strip Scan of Prescale with Auto-Nis - Evaluation of Nip-Width

Auto-Nis is a Windows based scanner and analysis software system that enables accurate interpretation and analysis of nip-impression by Fuji Prescale film stripes. The sensor film instantaneously and permanently changes colors proportional to the surface pressure when placed between the two nipped rolls.

Economical bands of only a few centimeters in width are sufficient to detect the nip impression. Place the stripe on the nip area of the opened roller . After closing and under the roller pressure of production the pressure sensitive film changes the color permanent. The color change is shows the nip-width and the intensity of the color is proportional to the pressure. Prescale films stripes can be obtained by Tiedemann as a service.

Auto-Nis scans can interpret the sensor film stripe up to a length of 12 m. It assimilates the data into a variety of easy to read graphical formats and displays of data.

Often nip-widths and pressure are not uniform along the length of the rolls. So readjustment is necessary and can be easily controlled by using Auto-Nis.

A final scan and print out of nip- impression documents the successful adjustment.
