Why Do Our Air Flow Sensors Print PBT-GF30

When you take our air flow sensor and see "PBT-GF30" logo on the housing, you may wonder what secret does this logo holding? In fact, this letters and numbers is our ultimate pursuit of product performance and quality, and the key to providing lasting stability for your vehicles or even customers.

"PBT-GF30" is a technical term in the field of materials science, where "PBT" refers to polyethylene terephthalate, a high-performance thermoplastic engineering plastic with excellent mechanical properties, electrical insulation and chemical corrosion resistance. "GF30" means that 30% glass fiber is added to the PBT material. The combination of these two materials gives the air flow sensor housing exceptional performance.

As core components of automotive engine management systems, the working environment is often challenging. The high temperature in the engine compartment can reach more than 120 ° C, which is accompanied by severe vibration and complex electromagnetic interference;In other environments, sensors may be exposed to corrosive substances such as oil, acid and alkali sometimes. Under such conditions, ordinary materials are prone to deformation, aging, insulation failure, etc., leading to deviation of measurement data, and even causing equipment failure. The housing of air mass sensor made of PBT-GF30 material can easily cope with these extreme conditions.The addition of fibreglass, so that the heat distortion temperature of the material to 200 °C above, effectively resist high temperature; Its stiffness and strength are increased 2-3 times, and its shock resistance is greatly enhanced, ensuring the stable operation of the precision components inside the sensor even in bumpy road conditions or high frequency vibration environments. At the same time, the combination of the chemical stability of PBT and the inert nature of the glass fiber makes the shell have excellent resistance to various chemical substances and prolong the service life of the product.

From the point of view of production process, PBT-GF30 material has good fluidity and high molding precision, which can meet the manufacturing requirements of the complex structure of the air flow sensor shell. Our housing design integrates sophisticated flow channels, sealing structures and electromagnetic shielding layers that not only contribute to the sensor's measurement accuracy, but also its sealability and resistance to interference. The excellent formability of PBT-GF30 ensures that every part of the design is accurately represented, enabling the sensor to achieve a high performance with a tolerance of size of micrometers.

In addition, the "PBT-GF30" logo is also our commitment to quality transparency. In the current market competition, some manufacturers use inferior materials or cut materials to reduce costs, resulting in uneven product quality. In choosing to clearly label materials information, we are not only confident in our technical strength, but also provide customers with a "visible" quality assurance. You can verify the ingredients of the material through a professional inspection department, and you can also feel the reliability and stability of the product in long-term use.

PBT-GF30 is not only a material logo, but also our relentless pursuit of excellent quality. GERTAY will continue to develop technological innovations to bring you superior air flow sensors with better materials and better processes, and work together towards a more efficient and reliable future for sustainable development.
