The machine use the high-performance servo dynamic control system, the oil pump as the power source, having the characteristics as follow: high response,saving energy, low noise, high-control precision, and have the breakthrough in the prefect connection of the electrical servo and hydraulic drive system.
High Energy saving
Under the ideal working state, Power consumption is 40% less than that of variable displacement pump and 70% less than that of fixed displacement pump, save the cost effectively.
High precision
Precise control of low pressure & low flow, repeating precision is less than 0.5%. Weight error of the products is 0.4%~0.7%, with semi-close loop system nearly.
Low noise
Different from ordinary fixed pump injection molding machine, servo power-saving injection molding machine is working only when necessary. And working noise is less than 70dB, will be much quieter for your working area.

Not designing the proper draft: This refers to the angle at which the finished product is ejected from the mold. An insufficient draft can lead to ejection problems, costing significant time and money.
Improperly placed or sized gates: Gates are the openings in a mold through which thermoset or thermoplastic material is injected. Each will leave a vestige (scar), which can create aesthetic or functional problems if not properly placed.
The number of parts (cycles) required, as well as the material they will be made of will help drive decision-making as to how and with what materials to create the mold.
When a product has been properly designed, approved, and die cast, it’s time to start the actual manufacturing! Here are the basics of the injection molding process…
Thermoset or thermoplastic material in granular form is fed through a hopper into a heating barrel. (Learn more about the differences between plastics in our PLASTICS course.) The plastic is heated to a predetermined temperature and driven by a large screw through the gate(s) and into the mold. Once the mold is filled, the screw will remain in place to apply appropriate pressure for the duration of a predetermined cooling time. Upon reaching this point, the screw is withdrawn, the mold opened, and the part ejected. Gates will either shear off automatically or be manually removed. This cycle will repeat over and over, and can be used to create hundreds of thousands of parts in a relatively short amount of time.
