In this test, a striker (tup) with specific geometry falls from a set height onto the specimen.<\/p>\n<p>The model manufactured by <strong>Polymer Test<\/strong> maximizes safety and accuracy by eliminating operator intervention in height adjustment and weight release.<\/p>\n<h3>Critical Feature: Anti-Rebound System<\/h3>\n<p>In drop weight testing, if the striker bounces after the first impact and hits the sample again (secondary impact), the polymer&#8217;s molecular structure changes, invalidating the test results. This machine is equipped with intelligent sensors and a fast-acting gearbox that catches the weight immediately after the first rebound in mid-air, preventing any secondary strikes.<\/p>\n<h3>Test Methods and Smart Control<\/h3>\n<p>Via a 4.3-inch touchscreen, this device enables the execution of two main impact test methods:<\/p>\n<ul>\n<li><strong>Staircase Method:<\/strong> Automatically adjusts the drop height or weight in steps to calculate the Mean Failure Energy (MFE).<\/li>\n<li><strong>Round-Clock Method:<\/strong> Applies impacts to different points around the pipe&#8217;s circumference (at different &#8220;hours&#8221;) to check production uniformity.<\/li>\n<\/ul>\n<h3>Technical Specifications<\/h3>\n<ul>\n<li><strong>Drop Height:<\/strong> Adjustable up to 2000 mm (2 meters) with 1 mm accuracy driven by a servo motor.<\/li>\n<li><strong>Sample Capacity:<\/strong> Features a robust V-Block support and clamping system to hold large pipes up to <strong>630 mm diameter<\/strong>.<\/li>\n<li><strong>Striker Variety:<\/strong> Supplied with various standard strikers (D90, D25, D20) and calibrated weights.<\/li>\n<\/ul>\n<h3>Complete Pipe Laboratory Setup<\/h3>\n<p>To set up a standard pipe quality control laboratory, in addition to impact testing, you also need internal pressure testing.
