The mudguard is a plate structure installed behind the outer frame of the wheel. It is usually made of high-quality rubber material, but also engineering plastics. The mudguard is usually installed on a metal baffle behind the wheel of a bicycle or motor vehicle, a cowhide baffle, a plastic baffle, and a rubber baffle. The effect after installation is that the mudguard is about 5cm protruding from the body. This 5cm effectively prevents flying stones and gravel from damaging the paint surface of the body.

Processing technology:
The specific processing technology of the fixed core is: material preparation (the material is P20, pre-hardened) → rough milling six sides → grinding benchmarks → punching and tapping → CNC rough machining → CNC finishing (precision is used at the peripheral corners of the fixed core Engraving) →Fine milling benchmark diagonal →Deburring →Rough polishing →Fine polishing. Absorb the lessons of the past, before the fixed mold core is subjected to CNC finishing, the workpiece should be subjected to stress relief treatment to prevent deformation and cracking of the workpiece.

The specific processing technology of the movable core is: material preparation (the material is P20, pre-hardened) → rough milling six sides → grinding benchmarks → drilling and tapping → CNC rough machining → CNC finishing → EDM → wire cutting → Finish milling reference diagonal → deburring → rough polishing → fine polishing.

The specific process of the core is: material preparation (the material is P20, pre-hardened) → rough turning → grinding reference and finishing turning → fine milling → (with mold). The processing technology of other parts can be carried out according to the conventional technology.
