About desktop injection mold

mold design
The location of the gate is designed to ensure that it fills the thick walls first to avoid stagnation and premature hardening of the polymer melt.

Increase the number of gates and reduce the process ratio.

Increase the size of the flow channel and reduce the flow resistance

Properly set the position of the exhaust port to avoid poor exhaust (see if the lower punch part is burnt)

Increase the number and size of exhaust ports

Cooling slug well designed to discharge cold slug

The distribution of cooling water channels should be reasonable to avoid local low temperature of the mold

injection molding machine
Check the check valve and the inner wall of the barrel for severe wear. The above-mentioned wear can cause serious loss of injection pressure and injection volume.

Differences Between Injection Molding and 3D Printing
Before looking into how they differ from one another, let’s take a look at their similarities first. Both processes involve creating physical objects by combining different materials together to make them stronger, lighter, or harder than before.

The only difference between them is that injection molding involves injecting molten material through channels, while 3D printing uses ink-like material to build up layers.

Using either method requires some kind of machine, but there are several differences between the machines used in both methods. For example, 3D printers are typically made for many smaller-scale jobs, while injection molding can be used for much larger projects.
