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.
