Injection Molding Machines
Next advancement in molding
Sumitomo Heavy Industries launched the injection molding machine industry in 1965. Since then, we have been developing technologies that have been leading the industry, such as all-electric machines equipped with the industry's first direct drive system and the revolutionary integration application “Zero-molding.” Our strength includes our robust lineup and precision/high-cycle molding, which contribute to the production of a wide variety of plastic products.

Getting as close to zero defects, losses, and faults as possible
Zero-molding is an integration application that achieves as close to zero defects, losses, and faults as possible.
This application consists of three elements, including MCM (mold clamping-related technology), FFC (filling-related technology), and the system SPS that easily operate these technologies.
MCM(Minimum Clamping Molding)
Reduce the maintenance work to utilize the vent effect and extend the mold life
Vent is clogged by excessive mold clamping force.
It can result in short shots and gas burns.
Gas is properly discharged from the PL sides.
It resolves short shots and controls mold deposits.
FFC(Flow Front Control)
Low pressure and smooth filling promote venting, improving the cavity balance
SPS(Simple Process Setting)
Error-free simple settings reduce preparation/operation time
Direct Drive System
High precision and highly responsive screw control
The latest control system ISCII (Intelligent Servo Controller II) controls the internally-developed low inertia servomotors.
It enables high precision and highly responsive screw control, realizing more precise and stable plasticization, filling, and pressure holding processes.
Toward the third generation of development
SE-S, which was released in 1997 and was the industry's first machine equipped with the direct drive, instantly and solidly established Sumitomo's all-electric technology.
The direct drive system symbolically represents the developmental philosophy of the all-electric technology and the wide range of the technical capabilities.
The direct drive directly communicates the required movements without going through unnecessary speed reducing devices between the servo motor and actuator. The drive has continued to evolve through enhanced low inertia moment and speed acceleration, and it is now in its third generation.
The performance has been significantly improving.
