【Si-IV Series Large Injection Molding Machines】
Highly rigid, wide platen specifications meet the requirements of the large molding machine market
- ・Although the die clamping force is 850 tons, the tie-bar spacing has been designed for a 1,000-ton class machine to accommodate one-size larger dies and permit greater freedom in die designing.
- ・Highly rigid and yet slim die plates with optimum profile distribute uniform die clamping force over the die parting surface resulting in energy conservation and high quality moldings.
New toggle clamping mechanism dedicated to large molding machines
- ・A dedicated toggle clamping mechanism with optimized link length and distribution ratio of the toggle mechanism was designed using a “toggle optimization program” developed in collaboration with Kyoto University. This mechanism reduces shock at the start of die opening and closing to ensure smooth die opening and closing operations.
TOYO's Built‐in Servo System BD100 / GD620
Built‐in Servo System
The BD and GD series injection units employ TOYO's BUILT-IN SERVO SYSTEM that directly connects the injection ball screw and servomotor, minimizes transmission energy loss by simplifying the mechanism structure, and achieves high torque from a compact motor by eliminating wasted inertia.
Designed with an emphasis on high acceleration and deceleration performance, on top of increased injection speed, this BUILT-IN SERVO SYSTEM demonstrates its effect in molding, for example, super-small capacity, small, precision parts, such as those represented by the fine pitch connector, and light guides for the LCD displays for monitors and mobile PCs when using medium and large injection molding machines.
Twice The Acceleration Performance
The adoption of a BUILT-IN SERVO SYSTEM enabled 10G acceleration* to be achieved, about twice that of a conventional high-speed unit, as well as improving maximum injection pressure by 17% (*) compared with the same conventional model. In addition, a high 800 mm/s* maximum injection speed was also realized.
*: With the BD100 model
New High-Speed, High-Precision Control System
These injection units incorporate a high response control system that enables high acceleration and deceleration motion control. Compared with conventional control system, communication speed is increased tenfold while scan time is cut in half, allowing the status of the servomotor to be monitored closer to real time.
The volume of communication information that can be transmitted has been increased dramatically, making it now possible to change parameters even while the machine is in operation.
TOYO's Super High-speed Injection Units
Super high-speed injection units are available for small, medium and large injection molding machines to meet the needs of the market. These units can mold ever-thinwall products, eliminate weld lines, minimize war page of moldings, and show great replication capability.
