Intelligent weight V/P control function, YIZUMI's core R&D achievement for all models, achieves product weight repeatability of 2%. In the production process, the controller monitors the pressure variations of plasticizing and uses algorithms to automatically adjust the holding pressure switchover point or the holding pressure, ensuring precise repeatability of product weight.
Intelligent mold-opening function is a standard feature, which can be activated and adjusted based on production requirements.
A6 series is equipped with preventive monitoring and maintenance function for key components, which provides timely reminders for machine maintenance and preicts potential issues, thus extending the machine's service life.
It offers intelligent real-time monitoring and detection for key components and indicators such as screw drive shaft bearings temperature, injection end position, clamping force, and the hydraulic system. With advanced algorithms, it identifies and alerts for potential risks, while also providing troubleshooting guidance.
A6 series is equipped with intelligent energy management system,enabling energy consumption data to be digitized and visualized.
The system automatically monitors the clamping force for each mold clamping. When the clamping force exceeds the setting deviation limits, automatic alarm is triggered, effectively preventing defective products due to abnormal clamping force.
If clamping force exceeds setting deviation, the system will smartly adjust the mold thickness during the next mold opening to ensure the clamping force returns to the set range.
Once injection is finished, the full clamping force is pre-released to prevent on increase in mold opening pressure or difficulties. This helps to shorten production cycle, lower energy consumption during mold opening, and reduce wear on the mold and machine, ultimately extending their service life.
Based on customer's actual product needs, more optional features of intelligent clamping force management system are available;
Intelligent clamping force sustaining Pro: Compared to the standard version, this offers more precise monitoring and better mold adjustment.
Intelligent clamping force optimization: Real-time monitor on clamping force changes during injection, intelligently analysis on product's actual molding requirements, and adjustment to optimal clamping force.
Clamping force balance monitoring: Real-time monitor on the stress on each tie bar and automatically alarms if the stress exceeds setting limits.
The A6 series has introduced a new upgrade with dual pressure-center platens, both fixed and movable platens utilizing YIZUMI's patented pressure-center structure. This design, optimized through simulation, provides excellent rigidity, reduces deformation, and supports better product molding.
A6 series features integral dual-layer support for injection unit as a standard configuration, with dual linear guides for both carriage and injection.
The A6 series features electric plasticizing as a standard configuration, ensuring reduced noise and energy consumption. Compared to hydraulic systems, eelctric plasticizing reduces energy consumption by 30% to 50%.
Green pasticizing function, as a standard feature for A6 series, will intelligently select screw speed based on cooling time to reduce plasticizing energy consumption.
At series is equipped with new energy-efficient hydraulic system, achieving average energy saving of over 12%.
The new drive system is designed to recover brake energy, making it more energy-efficient and eco-friendly.
Innovative "dual-drive" system that allows for parallel electric plasticizing, allowing for immediate plasticizing and significantly reducing cycle time.
The latest power system improves injection speed by an average of 9%, screw speed by an average of 30%, and plasticizing efficiency by an average of 20%.
The A6 upgraded design ensures shorter dry cycle, with a reduction of 14% to 25% across the entire series, resulting in enhanced efficiency.
