{"product_id":"maquina-de-soldadura-de-extrusion","title":"Extrusion welding machine","description":"\u003cp\u003eSealing critical points in HDPE geomembranes—pipe outlets, angled corners, repair patches, and perimeter reinforcements—with filler welding rod that restores full structural integrity, without the limitations of hot air without added material, requires a handheld extrusion welding gun with a powerful motor and integrated air preheating. This extrusion welding machine—also called a \u003cstrong\u003ehandheld extruder\u003c\/strong\u003e, extrusion welder, or extrusion welding gun—is manufactured by MOLTEXO with 3400 W of power, designed for professional geosynthetic installers, chemical tank manufacturers, structural plastic ducts, and critical repairs in civil engineering.\u003c\/p\u003e\n\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndependent dual heating system:\u003c\/strong\u003e hot air prepares the surface of the base material while the filler rod simultaneously melts, ensuring molecular fusion in both areas and eliminating thermal stresses that compromise joint watertightness.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e360° swivel head with adjustable shoe:\u003c\/strong\u003e allows welding at any angle and orientation, a critical condition for tank corners, pipe outlets in plants, and restricted access areas where the operator cannot maneuver freely.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e3400 W motor for constant flow:\u003c\/strong\u003e the sized power allows continuous extrusion of filler rod without flow drop during long sessions, a condition for heavy industrial work with multi-meter seams without stopping.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSafe cold start system:\u003c\/strong\u003e the motor does not activate until the melting chamber reaches temperature, preventing internal damage to the polymer and the motor itself, a condition that ruins generic extruders in a few months of careless use.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterchangeable Teflon shoes:\u003c\/strong\u003e different geometries (angle, overlap, fillet) according to the type of joint for the project, expanding versatility without investing in multiple tools.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTypical Applications and Uses\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSealing critical details in geomembrane installation: pipe outlets, corners, perimeter reinforcements, structural interfaces.\u003c\/li\u003e\n  \u003cli\u003eManufacturing and repair of chemical tanks, water reservoirs, and structural plastic ducts with HDPE or PP.\u003c\/li\u003e\n  \u003cli\u003eRepair of cracks and damage in installed geomembranes with filler rod that restores full structural integrity.\u003c\/li\u003e\n  \u003cli\u003eConstruction of special elements on site: containment ponds, sumps, sub-grade tanks, and custom non-standard elements.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eQuality and Durability\u003c\/h3\u003e\n\u003cp\u003eAn inexpensive extruder fails in two ways: the motor cannot withstand continuous extrusion of multi-meter rods (it burns out or loses torque within a few weeks) and the cold start system is absent or deficient (which leads to activations with unmelted material that break the motor). MOLTEXO works with a sized 3400 W motor and a safe cold start, which distinguishes a serious industrial-grade extrusion gun from a generic tool that fails in critical work.\u003c\/p\u003e\n\n\u003cdiv style=\"background-color: #F3F6F3; padding: clamp(14px, 4vw, 18px); margin-top: 20px; font-size: 0.9em; color: #555555; border-radius: 8px;\"\u003e\n  \u003cstrong style=\"color: #006902;\"\u003eAlso known as:\u003c\/strong\u003e\n  \u003cstrong\u003eTechnical:\u003c\/strong\u003e extrusion welder, handheld plastic extruder, extrusion welding gun, extruder welding gun, HDPE filler welder.\n  \u003cstrong\u003eIn DR and Caribbean:\u003c\/strong\u003e handheld extruder, extrusion gun, geomembrane extruder, extrusion welder.\n  \u003cstrong\u003eIn other countries:\u003c\/strong\u003e extrusion welder (USA), plastic extrusion gun (USA), extrudeuse manuelle (FR), portátil extruder (LATAM), extrusora gun (LATAM, ES), manual plastic extruder (MX).\n\u003c\/div\u003e","brand":"KORWINS","offers":[{"title":"3400 W","offer_id":52387126575432,"sku":"123765","price":510000.0,"currency_code":"DOP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0916\/9751\/2776\/files\/pistola-extrusion-manual-soldadora-geomembrana-equipo-portatil-santo-domingo.png?v=1780242265","url":"https:\/\/dodom.com\/en\/products\/extrusion-welding-machine","provider":"Dodom","version":"1.0","type":"link"}
