I. Hardware Procurement Costs
Core Communication Interface Hardware: Industrial communication gateway: approximately 1500-3000 RMB per unit; Industrial-grade PTP synchronous switch: approximately 2000-5000 RMB per unit; Industrial network card: approximately 800-1500 RMB per unit.
Field Signal Acquisition Hardware: High-precision RC parameter acquisition module: approximately 498-590 RMB per unit; Temperature fluctuation monitoring sensor: approximately 100-200 RMB per point; Electromagnetic environment monitoring module: approximately 800-1200 RMB per unit.
Auxiliary Supporting Hardware: Industrial-grade wireless Wi-Fi module: approximately 200-500 RMB per unit; Signal isolator: approximately 150-300 RMB per unit; Industrial-grade handheld PAD: approximately 2000-4000 RMB per unit.
Total Hardware Cost per Production Line: Approximately 25,000-40,000 RMB. Using high-performance, cost-effective domestic components can further reduce the cost to below 20,000 RMB.
II. Software Configuration and Integration Costs
MES System Secondary Development Costs: Custom development costs for adding an automatic RC calibration task trigger module are approximately RMB 10,000 to 20,000. Reusing the open interfaces of the existing MES system can reduce this cost to below RMB 5,000.
Debugging and Integration Costs: On-site engineer service for communication link debugging and rule configuration costs approximately RMB 8,000 to 15,000. Internal technical team debugging can completely eliminate this cost.
Total Software Integration Cost per Production Line: Approximately RMB 18,000 to 35,000. Self-developed debugging can be controlled to below RMB 10,000.
III. Long-Term Operation and Maintenance Costs
Annual Hardware Maintenance Costs: Approximately 5% to 8% of the total hardware investment. Annual maintenance costs per production line are approximately RMB 1,200 to 3,200.
System Iteration and Optimization Costs: Annual costs for adjusting calibration trigger rules based on process updates are approximately RMB 2,000 to 5,000.
Annual total maintenance cost per production line: Approximately 3200~8200 RMB, which can be further reduced through in-house maintenance by the internal maintenance team.
IV. Overall Investment and Return Comparison
The total investment for the entire lifecycle of a single production line is approximately 43,000~75,000 RMB, which can reduce annual losses from defective products caused by RC parameter drift by approximately 100,000~200,000 RMB, resulting in an investment-to-return ratio exceeding 1:2.
When adding injection molding machine locations later, the marginal incremental cost per machine is only approximately 2000~3000 RMB, making expansion costs extremely low.
