Ejection molder

Analysis of the flow through an ejection molder (see Figure 1.16). In... 

Injection molding involves two distinct processes. The first is melt generation, mixing, and pressurization and flow, which is carried out in the injection unit of the molding machine. The second is product shaping, which takes place in the mold cavity. Injection molders, therefore, have two distinct parts the injection unit and the mold/clamping unit. The function of the injection unit is to melt the polymer and inject it into the mold the function of the clamping unit is to hold the mold, open and close the mold, and eject the finished product. 

If the information is shallow, 0.05 mm (0.001 in.), it may be produced using etching, EDM, or sand blasting, and even can be put on side walls with little draft. The product can then be ejected without problems. Such applications should be discussed with a molder or mold designer experienced in this field.
