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.

China's manufacturing industry is undergoing transformation and upgrading, with the digitalization process accelerating to improve production efficiency, reduce production costs and enhance product quality. 

CNC stands for "Computer Numerical Control," commonly known as "numerical control." It is an automated machine tool equipped with a program-controlled system. This control system logically processes programs specified by control codes or other symbolic instructions, decodes them, and transmits them as coded digital representations via an information carrier to the numerical control device. After processing, the numerical control device issues various control signals, controlling the machine tool's movements and automatically producing parts according to the shapes and dimensions specified in the drawings.

Simply, internal stress is the mutually balanced stress that exists between molecules within a product when no external forces are acting on it. You can imagine it as a piece of plastic being pulled or squeezed from all directions by invisible hands.

One of the common defects of die castings.The die casting alloy liquid shrinks in volume during the cooling and solidification process.

Sandblasting is a surface treatment method that uses high-speed abrasive jets to impact and rub the workpiece surface to clean, remove rust, increase surface roughness, and improve coating adhesion.

In the injection molding process, melt degradation is the key factor that causes various defects such as burn marks, black spots, silver streaks, strength loss, uneven color, abnormal odor, etc. Controlling degradation is one of the core goals of process parameter setting.

PP, commonly known as polypropylene, is also known as "pleated plastic" for its excellent fracture resistance.

As the company continues to develop, the customer base will become more and more diverse, and customer demand for products will become more diversified. We will be exposed to more new surface treatment methods.
