PURPOSE:To mold a high-precision plastic lens with a large diameter by charging the plasticized material through the gate into the cavity of injection mold heated up over the temperature of glass transition point of the material, sealing the gate mechanically, and hardening the material by ...
1. Temperature conditions:Injection molding needs to heat plastic particles to a melting state, and generally the injection molding machine will set the heater of the heating cylinder, the cylinder and the mold to provide heating conditions. Different plastic materials require different heating temperatu...
After the pressure maintaining is completed, the plunger or screw of the injection molding machine will retract, which will release the pressure of molten plastic in the plastic mold cavity. At this time, the pressure of molten material in the cavity will be higher than that in front of the ...
The primary advantage of injection molding, and the overall molding process is the ability to scale production to your specific needs. Once the initial costs have been paid the price per unit during injection molded manufacturing is extremely low. The price also tends to drop considerably as more...

As a result, injection molding machines are designed to each accommodate a small range of this larger spectrum of values. Sample specifications are shown below for three different models (Babyplast, Powerline, and Maxima) of injection molding machine that are manufactured by Cincinnati Milacron. ...
