Recently, the national special research project Research on Pressure Measurement and Control in Polymer Extrusion Process Based on AI Intelligent Melt Pressure Sensors, led by Dr. Wu Hao, Global President of GRAEFF and a senior expert in the melt pressure sensor industry, has officially passed the review by the Professional Committee for the Transformation of Scientific and Educational Achievements of the China Commercial Joint-Stock Enterprise Economic Federation and successfully concluded. This marks a milestone breakthrough in GRAEFF’s application of AI technology in the melt pressure sensing field, injecting core momentum into the intelligent upgrading of the industry.

Confront industry pain points, break through technical barriers

In the field of polymer extrusion, accurate measurement and stable control of melt pressure serve as core links to guarantee product quality and production efficiency. For a long time, conventional sensors suffer from rapid accuracy attenuation, severe zero drift and insufficient stability in environments above 300℃, failing to meet the stringent requirements of high-end manufacturing and becoming a key bottleneck restricting the intelligent development of the industry.

Led by Dr. Wu Hao, the R&D team of GRAEFF has targeted industry pain points and carried out systematic technological research with AI algorithms and advanced material technologies as dual core drivers. Through long-term research, development and verification, the team has successfully launched the world’s first AI intelligent melt pressure sensor, achieving a number of key technological breakthroughs:

Extreme Environment Stability

Equipped with GAIM series AI zero temperature drift technology, it maintains long-term stable operation at 350℃, thoroughly solving the problem of zero drift under thermal working conditions.

High-precision Intelligent Regulation

The measurement error is controlled within ±0.25%. Millisecond-level real-time data collection, combined with the built-in AI model, dynamically compensates for accuracy loss caused by temperature changes and realizes precise pressure control.

Predictive Risk Prevention & ControlThe 

AI algorithm automatically analyzes pressure fluctuation trends and predicts process abnormality risks in advance. It upgrades the production mode from "passive monitoring" to "active regulation", empowering extrusion equipment with a "smart brain".

Achieve Practical Results, Empower Industrial Upgrading

At present, the research findings of this project have been widely applied on a large scale in multiple industries including plastics, chemical fiber and rubber. Practical data shows that production equipment equipped with the AI intelligent melt pressure sensor has increased production efficiency by over 30%, reduced energy consumption by 20%, and greatly lowered product defect rates, bringing remarkable economic benefits and competitive advantages to enterprises.

Dr. Wu Hao stated: "This is not a simple product iteration, but a leap of GRAEFF’s intelligent manufacturing in China from follower to leader in the high-end sensor industry. We always believe that breakthroughs in core technologies are the fundamental driving force for industrial progress."

Innovation as the Foundation, Forging a New Chapter in Intelligent Manufacturing

From project initiation to final conclusion, and from laboratory technology to production line application, the successful completion of this national research project serves as a powerful testament to GRAEFF’s strong R&D capabilities, as well as a vivid reflection of the brand’s in-depth industry cultivation and persistent innovation.

Going forward, guided by market demands, GRAEFF will continue to focus on key technical challenges across the industry, steadily advancing the research, development and transformation of core technologies. With more advanced and reliable sensing solutions, we will contribute to the high-quality development of the global intelligent manufacturing industry.
