This dataset realizes adaptive optimization of process parameters through real-time sensor data collection and fusion with reinforcement learning (Proximal Policy Optimization, PPO algorithm). Its core applications include: dynamically compensating injection temperature and holding time under environmental fluctuations (such as changes in temperature and humidity) to eliminate surface defects caused by material moisture absorption; intelligently matching the optimal process window based on the physical properties of multiple materials (PC/ABS/recycled plastics) to support green manufacturing needs; predicting mold wear or equipment faults through time-series data analysis and triggering early warning mechanisms to reduce unplanned downtime; combining digital twin technology to provide virtual process verification for customized products (such as special-shaped structural parts), shortening the mold trial cycle; meanwhile, linking the time-of-use electricity price strategy of the power grid through energy consumption optimization algorithms to reduce the electricity cost per batch. The model further enables rapid iterative R&D: inputting PLM design parameters can automatically generate adaptive process packages, shortening the new product launch cycle.

1. Data Collection and Cleaning
Collect environmental temperature, environmental humidity, injection temperature, injection pressure, material flow rate, holding time, mold number, production batch number, and equipment ID in real time via sensors.
Cleaning rules: Eliminate out-of-range injection temperature values, fill missing material flow rate values, and standardize data formats.

2. Reinforcement Learning Model Construction
State space inputs:
Static parameters: mold structure parameters, material type;
Dynamic parameters: injection temperature, injection pressure, ambient temperature and humidity, equipment health score.
Action space outputs: adjust injection temperature, injection pressure, holding time.
Reward function: calculated based on real-time qualified product rate, energy consumption optimization ratio, and parameter fluctuation penalty:
R=0.6⋅ΔQualified Product Rate + 0.3⋅(−ΔEnergy Consumption) −0.1⋅Parameter Fluctuation

3. Model Training and Optimization
Training data: Historical batch data with high real-time qualified product rates, verified for filling rate before pre-training.
Online update: Update the policy network based on real-time qualified product rate after each production batch, and record model tuning suggestions.
Migration adaptation: Reuse model parameters to adapt to new material types (such as recycled plastics).

4. System Verification and Anomaly Management
Digital twin verification: Input mold structure parameters and model tuning suggestions to calculate the filling rate, and put into production after reaching the standard.
Deviation monitoring: Compare the actual-simulation deviation rate, roll back parameters if it exceeds 2%.
Anomaly interception: Detect abnormal markings on pressure curves (standard deviation > 3 MPa) and freeze adjustments.

5. Deployment and Iteration
Edge deployment: Run the model on the factory edge server, record the model version number.
Dynamic iteration: Select high-qualified-rate versions through A/B test results (e.g., version B with a 1.2% increase in qualified rate).
