The <strong>Automatic Laboratory Hot Press<\/strong> is the standard solution for converting raw polymer pellets into uniform, stress-free sheets and films. Unlike manual presses, this automatic system controls every variable of the molding process\u2014pressure, temperature, and time\u2014ensuring that every sheet produced has the exact same crystallinity and physical properties.<\/p>\n<h3>Advanced Thermal and Pressure Control<\/h3>\n<p>To meet strict research standards, this machine offers:<\/p>\n<ul>\n<li><strong>Programmable Cycles:<\/strong> The <strong>4.3-inch Color Touch Screen<\/strong> allows users to set multi-stage programs (e.g., pre-heat, press, hold, cool) to match the specific melt flow of the polymer.<\/li>\n<li><strong>PID Temperature Control:<\/strong> Maintains plate temperature up to <strong>300\u00b0C<\/strong> with a precision of 0.1\u00b0C, ensuring uniform melting without degradation.<\/li>\n<li><strong>Integrated Cooling System:<\/strong> Features adjustable solenoid valves for water cooling. Controlled cooling is vital for thermoplastics to &#8220;freeze&#8221; the molecular structure correctly and prevent warping.<\/li>\n<\/ul>\n<h3>Designed for Efficiency<\/h3>\n<ul>\n<li><strong>Automatic Hydraulics:<\/strong> The pressure is applied and maintained automatically, eliminating operator fatigue and variation.<\/li>\n<li><strong>Non-Stick Molds:<\/strong> Supplied with Teflon-coated metal molds to ensure sheets release easily and have a smooth surface finish.<\/li>\n<\/ul>\n<h3>Complete Sample Preparation Workflow<\/h3>\n<p>Once you have molded a perfect polymer sheet, the next step is to cut it into standard test shapes. We recommend pairing this press with our <strong><a href=\"https:\/\/polymertest.com\/en\/product_en\/manual-hydraulic-dumbbell-punch-specimen-cutter\">Manual Hydraulic Dumbbell Punch<\/a><\/strong> to create precise dog-bone specimens for tensile testing.<\/p>\n<h3>International Standards Compliance<\/h3>\n<p>This equipment is designed to mold specimens according to:<\/p>\n<ul>\n<li><strong><a href=\"https:\/\/www.iso.org\/standard\/83779.html\" target=\"_blank\" rel=\"nofollow noopener\">ISO 293<\/a><\/strong>: Plastics \u2014 Compression moulding of test specimens of thermoplastic materials.<\/li>\n<li><strong><a href=\"https:\/\/www.astm.org\/d4703-16.html\" target=\"_blank\" rel=\"nofollow noopener\">ASTM D4703<\/a><\/strong>: Standard Practice for Compression Molding Thermoplastic Materials into Test Specimens.<\/li>\n<\/ul>\n<h3>Consultation and Purchase<\/h3>\n<p>To equip your lab with this essential molding tool, please click the <strong>&#8220;Contact for Purchase&#8221;<\/strong> button to reach our sales team via WhatsApp. You can also visit our <strong><a href=\"https:\/\/polymertest.com\/en\/contact-us\/\">Contact Us<\/a><\/strong> page for further specifications.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Automatic Laboratory Hot Press is a high-precision compression molding machine designed to transform polymer granules into uniform sheets and films.
