Measuring Single-screw Extruders for Labo Plastomill | 655

Measuring Single-screw Extruders for Labo Plastomill | 655

In small size extruder test of Labo Plastomill, in addition to detecting torque, the pressure and temperature (maximum 4 points each) are also continuously detected during molding by installing resin temperature sensor and resin pressure sensor in the cylinder or die and the values are displayed on the monitor. Various kinds of molding dies and take-off devices are also available, allowing you to determine molding conditions by simulating and obtain various information such as pressure, temperature, torque, specific energy (MJ/m3) and extrusion amount at each rpm (each shear rate) in addition to detecting mold status such as extrusion mold product’s fish eye, dispersion, transparency and gloss by using a small quantity of sample.

Fully-Automated Melt Flow Index Tester / Melt Flow Rater | 520-D-M

Fully-Automated Melt Flow Index Tester / Melt Flow Rater | 520-D-M

The Melt Flow Rater model D-M is a compact/bench-top Melt Flow Index Tester for determination of MFR (melt mass-flow rate) and MVR (melt volume-flow rate) in fully automatic mode according to ISO 1133 and ASTM D1238. Once samples are loaded to magazine, the sequence from sample filling to cylinder, MFR/MVR measurement, residue purging, data collection, and cleaning (cylinder/die/piston) is performed without human intervention.

Measuring Mixers for Labo Plastomill | 655

Measuring Mixers for Labo Plastomill | 655

Mixer heating block, that is the sample kneading part of Labo Plastomill, contains 2 kneading blades rotating in same direction or two kneading blades rotating in different directions and resin temperature sensors. Mixing and kneading of sample filled in the mixer proceeds as it receives heat and shear from the blade and its state of melting, dispersion, distribution, steadiness, deterioration, curing reaction, cross-linking, heat generation, etc.

Gurley type Densometer | 158

Gurley type Densometer | 158

The Gurley type Densometer measures the air permeability of paper and other materials. Transmit time (air permeability resistance) of 100cc and ISO air permeability can be displayed by automatically detecting falling rate of pressure cylinder. Features & Benefits ● Automatic calculation enabled by high-precision detection with the optical fiber sensors This tester correctly detects and counts the scale of air permeability amount with the optical fiber sensors.

Burst / Tear / Stiffness
FPC copper foil/thin-film Stiffness Testing Machine / Loop Stiffness Tester™ | 581-DA

FPC copper foil/thin-film Stiffness Testing Machine / Loop Stiffness Tester™ | 581-DA

The Loop Stiffness Tester™ is a compact testing machine used to evaluate the flexibility or rigidity of very thin plastic film, copper foil etc. When a specimen is set, it is automatically deformed into a “loop” shape and the compression resistance of the loop is measured by the load cell. In the case of evaluating the “stiffness” of thin specimens such as magnetic tape and plastic film, many conventional measurement methods are affected by the self-weight of the specimen itself, making evaluation difficult.

Handheld Rubber Tack Tester | Tackiness Checker™ | 236-HTC-1

Handheld Rubber Tack Tester | Tackiness Checker™ | 236-HTC-1

The Tackiness Checker™ is a convenient, easy-to-use instrument that was developed to allow on-site testing of the tackiness of rubber components. This instrument may also be used to test the tackiness of adhesive tapes, depending on the application. In the molding process of tires and belts, where components including rubber and reinforcement materials are bonded in multiple layers and vulcanized, it is very important to check the component tackiness before the forming process is completed.

Low Temperature Retraction Tester | 226

Low Temperature Retraction Tester | 226

The Low Temperature Retraction Tester evaluates the temperature at which a specimen reaches a certain specified contraction ratio while the temmperature of the specimen, which has been stretched to a certain level and frozen at a low temperature, is raised at a certain constant rate. The TR test is mainly used to determine the elastic recovery characteristics at a low temperature of the materials of which sealing performance is required, such as rubber seal components, hose etc.
