Engineering Plastic Tester

Product Details:

• Two kinds of display ways have been provided: digital and mechanical dial display. Digital display type has a function of automatical calibration of energy losses.
• High precision,perfect stability and easy operation enable the tester to gain CE certificate and be sold all around the world.

• The Impact tester is an instrument used to conduct impact tests on thermoplastic materials, in order to determine their impact fragility characteristics under specified stress conditions. There are three methods often used: Charpy, Izod and Tensile impact. These methods used differ in the way the specimen clamped and the impact energy & speed required.

• ISO 179, ISO 180, ISO 8256, ASTM D 256 and the equivalent.

Product Details:

FNCT determines the stress cracking resistance of polythene materials, when subjected to static tensile load in controlled environments like air, water and surfactant solution.

• FNCT is used to determine the stress cracking resistance of polyethylene materials in any environment. A test specimen in the form of a square-section bar with coplanar notches in each face at the center, is subjected to a static tensile load in a temperature-controlled environment, for example air, water, surfactant solution. The geometry of the specimen is such that plane strain conditions are obtained and brittle failure occurs under appropriate tensile load and temperature conditions. The time for this brittle failure to occur after loading is recorded.

• Features: 1.6 individual controllers, one for each station.
• Individual test bath for each station, temperature and force can be set individually.
• High accuracy of the regulation of force and elongation.
• Automatic diagnosis and with protective function.

Product Details:

• Six individual controllers, one for each station;
• Automatic smoke exhaust system provides a good test environment.
• Temperature protective system runs independently of the controlling system, is designed to prevent the test temperature not exceed the limit point.
• Programmed test operation can realize the functions of automatic timing to release the brake rigging and automatic recording the test time.
• Tensile stress-time double logarithm curve can be plotted automatically, internal linear regression method can calculate the tensile stress F(150/10) automatically.
• Software is capable of plotting displace-time, temperature-time and temperature-time curves, analyzing the tensile course, as well as saving and classifying test datum.

• It is designed to determine the elongational stress of ultra high molecular weight Polyethylene (PE-UHMW) molding and extrusion material. The elongational stress is a characterization of the melt viscosity of PE-UHMW moulding powder, whose melt flow rate cannot be determined by the method specified in ISO1133 because of its extremely high molecular weight.

• Heating medium: Methyl silicone oil
• Automatic lifting system for specimen supporter and smoke exhaust system

Product Details:

This device measures the resistance to external blows in thermoplastic pipes when subjected to blows from a falling striker of specific mass and shape dropped from specific height.

Features:

• Catching rate of anti-rebound device is 100%.
• Imported AC servo system guarantes the high locating precision and fast rising speed.
• Impact height may be set between 50 and 2000mm, also impact height may be calibrated automatically.
• Automatic security devices are provided in this instrument (specimen door,anti-rebound and striker window safeguard etc).

Application:

• The tester is mainly used to determine the resistance to external blows of the thermoplastics pipes of circular cross-section.Test pieces are subject to blow from a falling striker, of specified mass and shape, dropped from a known height onto specified positions around the circumference of the test piece. The true impact rate of the batch, or production run from an extruder, is estimated. The maximum value acceptable for the TIR is taken to be 10%. There are two test methods: round-the-clock method and staircase method.
