SED-CI Series

Multi-Shot Direct-Drive All-Electrics

Sumitomo Plastics Machinery’s SED-CI Multi-Shot Series of direct-drive all-electric injection molding machines delivers high-profitability double-shot molding with speed, precision, energy efficiency and ease of use – plus exceptional versatility.

Available in 83, 143 and 220 US ton models, the double-shot SED-CI Series combines dual injection units with a high-speed, high-accuracy rotating plate. The rotary plate enables the use of existing single-shot molds or integrated double-shot mold for significant flexibility and cost savings.

The SED-CI Series features direct-drive, Sumitomo AC servo motors with full closed-loop control and digital sensors. These beltless motors provide superior mechanical efficiency, repeatability and durability, and avoid the problems associated with belt adjustment and dust. Unique to Sumitomo’s advanced motor technology is a lighter, compact, low inertia design with the best mechanical configuration for each motion. The result is a low inertia system that:

• Provides the speeds, pressures and torque for the most demanding applications
• Draws power only as it is needed
• Is easier and faster to stop and start
• Provides exceptional precision and repeatability

Other features of Sumitomo SED-CI all-electric injection molding machines include:

• Sumitomo’s unique SK-II Control option for the industry’s highest levels of injection fill precision and peak pressure stability
• High injection speeds and hold pressures to meet the requirements of diverse applications including thin-wall molding
• Fast clamp open/close speeds for cycle time improvement
• Easy-to-use N-8 controller with full SPC and QC capabilities
• Selectable injection units, screw diameters and screw types to handle a wide range of molding applications and resins
• Sumitomo’s Center Press Platen (CPP) design field proven on both the SED and SE-DU Series
• Easy-to-use N-8 controller with full SPC and QC capabilities

The SED-CI is backed by a comprehensive Customer Satisfaction Program with Sumitomo’s standard-setting warranty program, worry-free parts, responsive field service and financing availability – plus advantages such as 3 days free in-plant training and expert processing assistance.

High-Speed, Multi-Shot All-Electrics

Sumitomo Plastics Machinery’s new, double-shot SEHS-CI Series of all-electric injection molding machines sets a new standard for high-profitability multi-shot molding with high speeds and exceptional precision, energy efficiency, versatility and ease of use. It combines Sumitomo’s advanced all-electric motor technology found on the high-speed SE-HS Series with two injection units and a high-speed, high-accuracy rotating plate.

The SEHS-CI is offered in two model sizes: the SE230HS-CI (253 US tons) and the SE280HS-CI (308 US tons). Designed with flexibility for a wide range of double-shot applications, the SEHS-CI:

• Has a wide mold space that accommodates existing single-shot molds or integrated double-shot molds
• Is available with a choice of injection units, screw diameters and screw types for shot sizes ranging from 2.9 to 10.7 ounces
• Delivers high injection speeds (300mm/sec) and high pressures (up to 41,248 psi)

Other features of the high-speed SEHS-CI all-electric injection molding machines include:

• 180° mold plate rotation in 0.8 seconds (compared with a typical 2.0 seconds, this achieves a 1.2 second reduction in cycle time)
• Faster mold open and close speeds of 1300 mm/sec (51.2 in./sec)
• Easy-to-use, PC-based N-9 controller with full SPC and QC capabilities
• Sumitomo’s Double Center Press Platen (DCPP) design that ensures superior surface pressure balance throughout the central surface area of the double-shot mold(s)
• A patent-pending, closed-loop clamp-force correcting system that uses a tie-bar mounted clamp-force sensor

The SEHS-CI is backed by a comprehensive Customer Satisfaction Program with Sumitomo’s standard-setting warranty program, worry-free parts, responsive field service and financing availability – plus advantages such as 3 days free in-plant training and expert processing assistance.
