From the 3D printing of the original shape to the plastic mold ready

Everyone loves the whole East Rail Line Extension process of creating inventions and developing designs, seeing the definitions combined together, working on optimization according to the original shape, and finally getting a design solution just right, reaching all the technical and aesthetic provisions. But you know what is stronger? Seeing your design in full production manufacturing.

But a design that looks good property management software and works well is only half the battle to achieve success. For most plastic parts, you have to design it for the injection molding process, which is the most cost effective technicality seen in the manufacture of many plastic parts. (For very unique three-dimensional geometries, parts are rarely cut with CNC, but typically cost 50-100 times more per part than CNC.) This has its own set of special rules, and with the following design options manual, you can maintain low mold costs and still have your molding look as good as it did before.

But before we get into the key prototype plastic parts point of how to adjust injection molding before 3D printing out the design, let's first look at the full manufacturing process, how does injection molding work?
Injection molding process basic
In terms of its key, injection molding is simple: 2 large metal material half-modules together, plastic or plastic material into the concave mold they produce, all the cooling, followed by the parts popping out, with the same time the two cut-off mold again separate out. Repeat this 10,000 times and you also have your first parts ready for sale. (The terminology quickly indicates that the angle at which the die moves is called the "die tension" and the line immediately around the intersection of the two cuts is called the "clinical diagnostic line.")
In fact, it will become more complicated. In general, even if the injected plastic materials are melted, they are not really heated: the raw material is pressed into the injection port (called the inlet) according to a large auger. As the raw material is reduced, it is heated up and gradually injected into the mold.
The mold itself must be the "film" of the part being molded, and the geometry becomes more and more complex. If you look at a very simple red mug, the kind we play beer-spilling ping-pong with in college, you can see how the inside of the mug is created by the geometric shape of half of the mold, and the outside is created by the other half of the mold. It's very simple, you've got a big cylinder sticking out of one side and into the other.
