1Manufacturing precision
If numerous trial runs are conducted to determine optimal process settings, then product quality is improved, but time consumption and cost increase
Solution Approach 1:
The patent applies preliminary action by using a computer simulation model to predict optimal injection molding process settings before actual production trials. The simulation model, which incorporates mold geometry, material properties, and process parameters, allows the system to determine suitable process settings in advance, thereby reducing the number of physical trial runs needed to achieve desired product quality.
2Manufacturing precision
If numerous trial runs are conducted to determine optimal process settings, then product quality is improved, but cost increases
Solution Approach 1:
The system performs preliminary simulation calculations to determine optimal process settings before actual production. By using the simulation model to predict the outcomes of different process parameter combinations, the system avoids costly physical trial runs, thereby reducing material waste, energy consumption, and overall production costs while still achieving high product quality.
3Manufacturing precision
If process settings are determined through trial runs at one location, then local product quality is optimized, but transferability to different locations deteriorates
Solution Approach 1:
The patent implements universality by creating a simulation model that can be applied across different injection molding locations and conditions. The model incorporates fundamental physical principles and material properties that remain consistent regardless of location, allowing process settings determined through simulation at one site to be transferred and adapted to other locations, thereby improving the system's versatility and reducing the need for location-specific trial runs.
