Servo Machines Features
1. High energy savings
Under normal operating conditions, compared with conventional
hydraulic injection molding machines, energy savings of 20-80%
can be achieved.
2. Molding stability
Compared with conventional injection molding machines repeatability is greatly improved due to servo motor closed-loop control.
3. Quick response
Featuring a dynamic servo motor with a response time of only 0.05sec
4. Quiet operation
The machine runs at much lower noise levels, particularly in low speed applications.
5. Reliable holding pressure
Compared with traditional hydraulic machine the holding pressure is more stable and does not have limitation.
6. Better oil temperature stabitily
The servo system only delivers hydraulic oil as it is needed for the various functions. This prevents unnecessary generation of heat and substantially reduces oil cooling requirements.
Servo energy-saving system
Using the servo motor oil esectriciyt composite sturcture, high response, low noile and excellent
electricity -saving performance.

Beryllium-Copper alloy: Typically used in areas of the mold that need fast heat removal or where shear heat is concentrated.
Just as with overall product design, mold design is another opportunity to prevent defects during the injection molding process. We have previously written blogs on the Top 10 Injection Molding Defects and Avoiding Mistakes in Injection Molding, but here are some examples of how poor mold design can be a costly mistake:
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.
