3-Axis Servo Hot Plate Welder
Main Features
1. The upper and lower dies are precisely positioned via servo control with an accuracy of 0.01 mm. The servo-controlled feed depth for the hot die is also accurate to 0.01 mm, providing better control over welding depth and material overflow to achieve superior results.
2. Parameters such as welding temperature, heating time, cooling time, welding depth, pressure, and transition time are all adjustable.
3. Moving parts utilize linear guides and servo motors to ensure smooth and precise motion.

Product Advantages
High weld strength; meets airtightness and watertightness standards
Plastic molecules melt and fuse, resulting in weld strength exceeding 80% of the base material; consistently achieves IP67 water and air tightness, perfectly resolving leakage issues in automotive radiators, headlights, new energy battery casings, and bathroom plumbing fittings-far superior to adhesive bonding.
Intelligent multi-mode welding, compatible with various plastic parts
Supports four process modes: time mode, displacement/penetration mode, constant pressure mode, and energy monitoring mode; features built-in material allowance compensation, ensuring qualified products even with slight dimensional deviations in injection-molded parts, significantly reducing scrap rates.
Independent Zone-by-Zone PID Precision Temperature Control
Multi-zone independent temperature control of the heating plates with an accuracy of ±1–2°C ensures uniform heating of large-area and irregularly shaped workpieces; real-time temperature measurement via thermocouples triggers automatic alarms for overheating or heating element failures, eliminating localized over-welding, under-welding, and yellowing or burning of the material.
Compatible with Materials Unsuitable for Ultrasonic Welding
Specializes in PP, PE, thick-walled parts, large-sized irregularly shaped parts, soft TPE rubber, glass-fiber-reinforced nylon, and double-layer composite plastics; unrestricted by workpiece thickness or structure, enabling large housings, hollow water tanks, and bumpers to be fully welded in a single pass
Significantly Improved Production Cycle Time
Faster servo response and rapid hot plate retraction reduce heat dissipation losses, shortening the single cycle by 20%–50%; Can be integrated with assembly lines and robotic arms for fully automated production lines, supporting continuous three-shift operations with an overall equipment effectiveness (OEE) of ≥92%.
Energy Savings of 30%–40%
Servo motors operate intermittently, consuming power only during the welding action, with extremely low standby power consumption; no need for continuous air supply from an air compressor or prolonged operation of a hydraulic station, resulting in significant long-term savings on electricity costs; no costs associated with regular replacement of consumables such as air hoses or hydraulic oil.
