Japan Steel Works

Japan Steel Works (JSW) is a Japanese industrial machinery manufacturer founded in 1907 and one of the world's largest producers of full-electric injection molding machines. Alongside horizontal and vertical injection molding machines, JSW also builds magnesium injection molding machines, extrusion lines and blow molding machines.

What Japan Steel Works manufactures

• Full-electric injection molding machines from 30 to 3000 tons of clamping force
• Vertical injection molding machines for insert molding and assembly operations
• Magnesium injection molding (thixomolding) machines for lightweight metal parts
• Multilayer blow molding machines and extrusion lines

Why a JSW machine in your production

Every system on a JSW electric machine is driven by an individual servo motor, and every servo motor has an absolute encoder. The result is system accuracy down to 0.01 mm — CNC-level precision — that does not drift as the machine warms up during a shift, because there is no hydraulic oil whose viscosity changes with temperature.

• Precision and repeatability that hold dimensional tolerance on thin-wall and technical parts alike
• Shorter cycle times thanks to the parallel movements that independent servo drives allow
• Less scrap, because the first part after a stoppage is already in tolerance with no warm-up
• Up to 60% energy savings and significantly lower cooling medium consumption
• No hydraulic oil — no replacement, no cooling, no disposal of used oil
• Lower maintenance costs and fewer unplanned stoppages
• Quieter, cleaner operation, suitable for cleanrooms and for working close to operators

Together these improvements affect overall production quality and profitability directly — most of all on high-cycle-count runs, where the difference in energy consumption and scrap multiplies across the year.

Japan Steel Works in Serbia and the region

Perotec Systems is the authorized representative for Japan Steel Works in Serbia, Croatia, Bosnia and Herzegovina, North Macedonia and Montenegro.

That means you do not negotiate a JSW machine with a factory in Japan: from us you get the quotation and a configuration sized for your part and cycle, delivery and customs clearance, on-site installation and commissioning, training for operators and process engineers, original spare parts and service for the life of the machine. We size the auxiliary equipment alongside the machine — temperature control unit, chiller, dryer and dosing unit and robot — so the whole line runs as a coordinated system.
