HES160H43C

Based on the mission statement, "To provide innovative, clean and energy-efficient solutions for a better tomorrow", Delta is committed to developing advanced variable frequency control technology for enhanced efficiency and greater energy-savings. Plastic products are widely used in our living environment for daily commodities, electronic devices and automotive components. Injection molding machines play a key role in plastic products production. There are four major energy consuming units in a traditional injection molding machine including the hydraulic pump, the heating unit, the cooling system, and the control system components. The hydraulic pump system consumes the most energy and accounts for more than 75% of the total power consumption in an injection molding manufacturing process. An injection molding cycle consists of several stages from mold closing, injection, pressure holding, plasticization, mold opening to ejection. Each stage requires a different pressure and flow. The oil pump motor is under variable loading. Traditionally, the overflow valve and the ratio valve adjust the excess pressure and flow that occurs at each stage. This process is known as "high-pressure throttle". It accounts for 40%~75% of the energy lost. The Delta Hybrid Energy Saving System HES-C Series provides precise pressure and flow control, eliminating energy loss in the high pressure throttle process. It helps injection molding machines save energy while enhancing productivity and precision. The Delta HES Series provides the best solution for injection molding machines.

System Features

(1)Significant Energy Reduction

A field test with an 850-ton injection molding machine adopted the Delta HES250M43 double-pump confluence hydraulic system.

The Delta HES-C Series saved up to 109,500 kWh in energy consumption and reduced 69,861 kg CO2e emissions in a year compared with competing products operating 24 hours per day.

(2)Excellent Overload Capability

■ All HES-C models feature overload capability of max. pressure 175bar for 60 seconds which is especially suitable for thick products production. Please refer to the Pressure-Flow Characteristic Chart on the following pages for more details.

(3) Cost-Effective System

■ Delta Hybrid Energy Saving System HES-C adopts Hybrid Servo Drive VFD-VJ Series and Fan Cooling Servo Motor MSJ Series, and features high torque and low inertia. Allowing users to select Hybrid Servo Drive VFD-VJ Series and Servo motor MSJ Series with lower power rating to save system cost.

(4)PID Pressure Control

■ Using Delta's special PID control technique, the

system is able to perform pressure overshoot

under 3 bar with optimized response time and

stable product weight.

(5)Field-Weakening Control of a Motor

■ Delta's servo drive uses motor field-weakening

control to effectively extend the motor operation

scope, increase system flow and ensure productivity

of the injection molding machine.

(6)Easy Commissioning

■ Users can directly use the Delta preset motor and hydraulic system parameters without the need for additional

tuning, simply install the drive to easily begin the operation.

(7)Excellent Performance

■ Short response time enhances response speed

of the system

■ Great V/P transfer capability elevates product

yield rate

■ Lower noise compared with traditional dosing

pump

■ Stable oil temperature rise

(8)S-Curve Control

■ Smooth operation reduces machine vibration

(9)Multiple Protections

■ Multiple protection functions, including over current, over/low voltage, over heating, brake protection,

insufficient pump oil protection. Complete protection prevents the equipment from anomalies and

serious malfunction, and enhances system lifetime.

■ Real-time monitoring of the motor temperature via KTY84-130 temperature sensor embedded in the

motor winding.

(10)Multiple Pumps Control

■ Capable of controlling up to 12 pumps and multiple master/slave pumps system architecture. Users can integrate systems with a different HES-C flow rate depending upon the system requirements of the machines. 

(11)User-Friendly Software

■ User-friendly software for machine commissioning.

The software presents real-time system parameters

such as pressure, flow, motor current and motor

speed.

(12) System Monitoring and Controller Integration

■ Built-in PG and communication card, and USB port

to connect industrial 3G routers for system monitoring

and software upgrade.

■ Supports CANopen communication protol, enhancing

integration with the controllers
