Die Casting Machine PLC Brand,Siemens vs Mitsubishi,It is recommended that customers choose a comprehensive selection.
Die Casting Machine PLC Brand–Siemens PLC
Mainstream series: S7-200 (discontinued), S7-300 (mid-to-high-end), S7-400 (high-end), S7-1200 (small and medium-sized), S7-1500 (flagship).
Die Casting Machine Application Case
The S7-300 series is widely used for die casting machine hydraulic system control, supporting complex logic and motion control.
The S7-1500 series excels in anti-interference capabilities and diagnostics, and supports channel-level fault identification.
Haichen HCD series die-casting machines use Siemens PLC to optimize the injection system and human-machine interface.
Die Casting Machine PLC Brand–Mitsubishi PLC
FX series (small), Q series (high performance), iQ-F (compact), MELSEC-Q (integrated control).
Die Casting Machine Application Case
The FX5U series has 150 times the response speed of the FX3U in packaging machinery, which is suitable for high-speed and high-precision scenarios.
The Q series supports multitasking and integrated motion control for fully automated processes in die casting islands.
The Mitsubishi FX2N series is common in low-cost projects, supporting cycle operation and single-step commissioning.
Software tools and programming environment
Siemens TIA Portal
Support multi-language programming (LAD, FBD, STL), high integration, but steep learning curve.
The Portal platform supports network configuration and remote diagnostics for complex systems.
Mitsubishi GX Works
The interface is simple and the ladder programming is intuitive, which is suitable for rapid development.
Provide a rich command library, but cross-brand integration requires adaptation protocols
Reliability and anti-interference capabilities
Siemens
The S7-300/400 series adopts a centralized installation design with integrated filtering in hardware.
But signal line shielding and grounding measures still need to be optimized in strong electromagnetic interference environments.
Yizumi’s case shows that analog signals are susceptible to DC 5V interference in long-term transmission, and additional anti-interference design is required.
Mitsubishi
The case combined with the touch screen shows that the Q series PLC has outstanding stability in high-temperature.
And dusty environments through software filtering and frequency conversion speed regulation technology, and the malfunction rate is close to 0.
Failure rate data
Siemens PLCs have a failure rate of less than 0.5% in heavy industries such as steel and chemicals, thanks to their modular design and self-diagnostic function.
Mitsubishi PLC has a failure rate of about 1.2% in injection molding machines and small and medium-sized die casting equipment, but its servo control system performs better in complex motion control.
Comparison of cost structures
Siemens
High-end models, such as the S7-1500, have a higher cost per unit, but their analogue modules are less expensive, making them suitable for die casting systems that require multi-sensor integration.
Mitsubishi
The price of the FX series entry-level PLC is 30%-50% lower than that of Siemens, and the Q series medium-sized PLC is cost-effective, suitable for small and medium-sized projects with limited budgets.
Maintenance and long-term costs
Siemens’ modular design reduces maintenance complexity, but the cost of spare parts is higher (e.g. S7-400 hot-swappable module).
Mitsubishi’s localized supply chain, such as the Dalian plant, shortens the lead time for spare parts and reduces long-term maintenance costs by 15%-20% compared to Siemens.
After-sales service system
Siemens
The global technical support network covers 100 countries, providing 24×7 hours of remote diagnosis (such as Yizumi’s PLC remote service model), but the on-site service response time is an average of 48 hours.
The training system is perfect, and STEP 7 and TIA Portal programming courses are regularly offered, which is suitable for enterprises that need in-depth customization.
Mitsubishi
The Asia-Pacific service center has a response time of < 24 hours and provides “replacement repair” service (refurbished products are as low as 3% off).
Which is suitable for small and medium-sized enterprises that urgently need to resume production.
The programming software (GX Works) has a low learning barrier and rich community resources.
But advanced functions (such as motion control) require additional training.
