Tire Pressure Monitoring Systems (TPMS) are critical for driving safety, monitoring tire pressure (0.1-3.5bar) and temperature (-40°C to 80°C) to prevent tire blowouts. TPMS sensors are installed inside wheels, exposed to extreme conditions—high vibration (10-2000Hz), temperature fluctuations, rain, snow, and road debris. These sensors require stable, sealed structures to ensure reliable performance in these harsh environments. Traditional welding methods may not provide sufficient sealing or structural strength, leading to sensor failure and inaccurate pressure readings. DaokeDao plastic laser welding provides IP67-level hermetic sealing, effectively blocking moisture, dust, and road debris from entering the sensor housing. The welds are strong and resistant to vibration and impact (impact strength ≥12kJ/m²), ensuring that the sensor remains intact even under extreme wheel conditions. The non-contact process avoids damage to internal sensor components, maintaining accurate pressure and temperature measurement (measurement error ≤±0.05bar). Our laser systems feature precise positioning accuracy (±0.01mm), ensuring that the weld joint does not interfere with sensor performance. They support small, compact sensor designs (size ≤30mm×25mm×15mm), adapting to the limited space inside wheels. With fast cycle times (6-8 seconds per unit) and consistent quality, our systems support mass production of TPMS components, helping manufacturers improve driving safety and reduce售后故障率 by up to 28%.
