Is the machine action the result of pressure or flow? What is the relationship between them?

The main materials used in 3D printing include liquid resin (SLA), nylon powder (SLS), metal powder (SLM), and filament (FDM). Liquid resin, nylon powder, and metal powder occupy the vast majority of the industrial 3D printing market.

Cold shuts/cold joints are also common defects in die castings, particularly magnesium alloys, which are particularly susceptible due to their material properties.

Sheet metal processing is a technical endeavor. To produce high-quality pieces you need not only excellent technique but also high-precision equipment. Among the many sheet metal processes, brushing (creating a brushed finish) is one of the most common and widely used.

Injection pressure refers to the pressure exerted by the plunger or screw tip on the plastic melt. Its function is to overcome the flow resistance of the plastic melt from the barrel into the mold cavity, allowing the melt to fill at a certain rate and compacting the melt to compensate for shrinkage.

Flash can also be called: flying material, seam, burr, flying wing, escaping material, and bulging mold.

1.The problem of striped pigment bands on products under sunlight needs to be considered from two aspects:

Porosity, a common internal defect in die-castings, is a regularly shaped, smooth hole formed by trapped gas. Porosity, or pinholes, are currently one of the most significant defects in die-castings. Controlling porosity is particularly critical in areas that require sealing.

In the precision world of mold manufacturing, every step is crucial. Once the mold is designed, high-quality steel forms the skeleton, while sophisticated machining technology is the key to giving the mold its soul. 

Mold sticking phenomenon (mold sticking, adhesion, friction ablation): During the die casting process the alloy adheres to the core, the cavity partially or even the entire cavity.
