The injection molding technique has a number of distinctive advantages that make it a desirable option in many circumstances. Let's examine these advantages in further detail, as well as the situations in which they are most useful.
Dimensional Possibilities
Due to the way the technique works, almost any shape you can imagine can be formed using injection molds. The possibilities are now only limited by your technical prowess and creativity. Making a gear with spokes or teeth, for instance, may be a laborious and time-consuming task when using a technology like CNC machining.
When compared to injection molding, this You may have molds produced to make the shape you require and perhaps manufacture several of the same gears in a very short period of time rather than starting with a piece of material and molding each feature one at a time.
Even though different materials would be utilized in these two very different procedures, utilizing injection molding has the potential to save a significant amount of time and money. Another illustration is a gear.
Due to the same flexibility, awkward forms are also excellent candidates for injection molding. Any form may be molded as long as it can be carved into the mold to get the desired shape. To ensure that the desired shape has enough integrity to be molded and perform as intended, it is still critical to concentrate on design quality.
The use of traditional or RAM EDM in the mold-building process is one of the elements influencing this versatility in geometrical possibilities. Conventional EDM employs specialized electrodes with a regulated electrical current to remove material, as opposed to conventional machining using a mill or lathe. This enables the creation of distinctive forms since the electrodes must be adjusted for each task. Standard cutter sizes and many other restrictions common to conventional machining do not apply to the cut geometry.
A high rate of production
Injection molding is a rather quick procedure when compared to many other ways of providing manufacturing services. The cooling step takes about half of the average cycle time, although generally, the procedure is quick. Again, comparing this technique to machining, under certain conditions with the right geometry and fixtures, gang runs are feasible. With injection molding, the mold may simply be constructed with several cavities that have the same shape—the essential term here is "some circumstances." This will make it possible to produce several pieces in a single cycle.
Because of the very quick cycle durations of injection molding, the discrepancy is even more apparent when we consider the time it takes to produce a single item. You are already creating numerous components every cycle if the mold is built with multiple cavities. As a result, we now have a procedure that can quickly produce a number of pieces. Similar pieces would probably have to be created one at a time using standard machining. The time required to produce a single product would probably be several times longer than the quick injection molding cycle time.

Materials Options
A significant majority of the materials utilized in this process are thermoplastics. This is because of their special physical characteristics and how they work with injection molding.
The word "thermoplastics" is rather broad and covers a staggering array of distinct materials. Before moving on to the specific materials, you have to filter through a sizable number of subclasses in this class.
The sheer variety of materials that may be utilized in the injection molding technique allows for a great deal of freedom in both the products' types and designs.
Each item may be made from a variety of materials, if desired. Some injection molding machines can do this specific operation. This may be as easy as using two distinct shades of PVC for aesthetic reasons, or it could include adding a whole new material for practical reasons, like a grip pad.
