Hot Plate/
Welding

Hot Plate Welding Machines are parts of the EUROMODEL standard machinery. Thanks to decades of R&D, today we have a remarkable know-how related to this technology.

Hot-plate welding is the most suitable system for joining large components with even complex geometries. After cooling, the welding shows an excellent aesthetic quality and is characterized by a very resistant and watertight joint. This procedure allows to join elements that have a certain degree of dimensional tolerance. Virtually all thermoplastics can be welded together, despite different stiffness.

Machinery

EUROMODEL standard hot plate welding machines are:

  • Available in more than 5 standard sizes, with electrical motion controls and the chance to install a feeding turntable.
  • Rapid tool change with quick coupling (15 minutes between two suitable parts from different model)
  • Tool Models Recognition and Storage of Recipes Parameters.
  • There is a thermal protecting shield to screen the operator when loading/unloading.
  • All tailor-made extras are available: Force control, Pre-heating cabinets, UPS, Air filter system, Automatic plugs system, traceability integration, Robotized loading/unloading management, Cleaning blades Brushings and so on.
  • Mobile door for frontal protection, with double safety level for operator (Light curtains and contact sensors)
  • Linear interpolation of axes to optimize fusion/welding phases. Precision in movements is +/- 0.05 mm.
  • All Welding Data (times, temperatures, pressure, and penetration) can be stored and associated with the QR / bar code and interfaced with the factory traceability system.

Tools/equipment

Tools and hot plates are CNC milled according to CAD geometry. Light weight design as per EUROMODEL standard to reduce heating/cooling time. Separate temperature management for each critical area of the hot plates.

Heating with perimeter resistors to attain an excellent temperature distribution (+/- 5º in contact zone). Accessible resistors for easy change and intermediate connectors. Consumption control of resistor groups to identify burnt-out resistors. Alarm alert shown on screen.

Fixtures are polished and/or coated to avoid any aesthetic damage to the parts. Suction caps and pneumatic clamps. Component presence recognition and sensors for correct positioning of parts.

All tailor-made extras are available: Barcode Reader Installation, Camera Checks, Poka-Yoke Design, Automatic Plugs System, Robotized loading/unloading for parts and so on during the loading phase. Equipment encoded with binary code with associated welding parameters in machine.

Joined Parts

This type of welding ensures the correct assembly of parts with complex geometry, obtaining high precision and an excellent aesthetic result.

The parts are welded with a continuous bead that ensures good mechanical strength and leak proof sealing.
