If the sample edges are rough or nicked, the material will tear prematurely during testing, leading to false data. The <strong>Manual Hydraulic Dumbbell Punch<\/strong> is the ideal solution for laboratories that need to cut standard &#8220;dog-bone&#8221; shapes without the high cost of a pneumatic press.<\/p>\n<h3>Hydraulic Power for Clean Cuts<\/h3>\n<p>While mechanical lever presses struggle with thicker or harder rubbers (Shore A > 70), this machine uses a <strong>Manual Hydraulic System<\/strong> to generate significant cutting force with minimal operator effort. Key benefits include:<\/p>\n<ul>\n<li><strong>High Cutting Force:<\/strong> Easily cuts through multi-layered rubber, leather, and semi-rigid plastics.<\/li>\n<li><strong>Interchangeable Dies:<\/strong> The system accepts various cutting dies (knives) to produce different shapes, such as Dumbbells, Rectangles, or Crescents.<\/li>\n<li><strong>Durability:<\/strong> Rugged construction suitable for harsh industrial environments, from small workshops to mass production quality control.<\/li>\n<\/ul>\n<h3>Versatility in Material Testing<\/h3>\n<p>This punch is essential for preparing samples for:<\/p>\n<ul>\n<li><strong>Tensile Testing:<\/strong> Cutting ASTM D638 or ISO 37 Type 1\/2\/3 dumbbells.<\/li>\n<li><strong>Tear Testing:<\/strong> Preparing &#8220;Trouser&#8221; or &#8220;Angle&#8221; tear specimens.<\/li>\n<li><strong>Compression Set:<\/strong> Punching out standard discs.<\/li>\n<\/ul>\n<h3>The Next Step: Testing<\/h3>\n<p>Once your high-quality samples are cut, they are ready for mechanical characterization. This machine is the perfect companion to our <strong><a href=\"https:\/\/polymertest.com\/en\/product_en\/electromechanical-universal-testing-machine-tensile-compression\">Universal Testing Machine (UTM)<\/a><\/strong>, ensuring your test results are based on perfectly dimensioned specimens.<\/p>\n<h3>International Standards Compliance<\/h3>\n<p>Depending on the cutting die installed, this machine prepares samples compliant with:<\/p>\n<ul>\n<li><strong><a href=\"https:\/\/www.iso.org\/standard\/86892.html\" target=\"_blank\" rel=\"nofollow noopener\">ISO 37<\/a><\/strong>: Rubber, vulcanized or thermoplastic \u2014 Determination of tensile stress-strain properties.<\/li>\n<li><strong><a href=\"https:\/\/www.astm.org\/d0638-14.html\" target=\"_blank\" rel=\"nofollow noopener\">ASTM D638<\/a><\/strong>: Standard Test Method for Tensile Properties of Plastics.<\/li>\n<li><strong><a href=\"https:\/\/www.iso.org\/standard\/527-1\" target=\"_blank\" rel=\"nofollow noopener\">ISO 527<\/strong> and <strong>ASTM D412<\/strong>.<\/li>\n<\/ul>\n<h3>Consultation and Purchase<\/h3>\n<p>To order specific cutting dies or the machine itself, please click the <strong>&#8220;Contact for Purchase&#8221;<\/strong> button to chat with our team via WhatsApp. You can also visit our <strong><a href=\"https:\/\/polymertest.com\/en\/contact-us\/\">Contact Us<\/a><\/strong> page for more information.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Manual Hydraulic Dumbbell Punch is a robust sample preparation device designed to cut precise &#8220;dog-bone&#8221; or dumbbell-shaped specimens from sheets of rubber, soft plastics, and elastomers.
