II. Common Causes of Crack Defects
1. Material issues
An improper ratio of Fe, Cu, and Si in the alloy composition leads to unstable material properties and a tendency to crack.

During the injection molding melt flow process, some flow patterns have been proven to be close to the actual flow state. These flow patterns form a fixed flow state within the mold, and the quality state formed under this flow state can be predicted. Therefore, 

Upgrading sheet metal equipment to improve sheet metal processes is a common practice among domestic enterprises. However, within just a few years, sheet metal equipment has stagnated, and it's a bold prediction that there may be little change in sheet metal equipment over the next few years or even a decade. Simultaneously,

CNC engraving machines excel at precision machining with small tools and are capable of milling, grinding, drilling, and high-speed tapping. They are widely used in various fields such as the 3C industry, mold industry and medical industry.

The cracks in the casting are visible to the naked eye due to external mechanical forces. Analysis of the casting's structural shape and defect appearance determines that the cracks are not caused by casting stress.

Anodizing is a widely applicable process for aluminum, zinc, magnesium, titanium, and other non-ferrous metals and alloys.

First, let's understand some definitions:Newtonian fluid: A fluid whose viscosity is unaffected by the shear rate applied to it. The viscosity remains constant as the shear rate changes.

Die-cast parts have become "metal twisters"?This isn't some special effect, but rather a common deformation defect in die-cast parts.

Numerical control machining is the manufacturing and processing of parts and products under computer control.

Laser cutting technology primarily uses a focusing lens to focus a CO2 laser beam on the surface of a material, melting it. At the same time, compressed gas coaxial with the laser beam is applied to blow away the melted material, allowing the laser beam and the material to move relative to each other along a specific trajectory, thus forming a slit. With the advancement of science and technology, laser technology has developed rapidly.
