The deburring process in casting involves of removing unwanted burrs, excess sharp edges and flash on the partline of die casting parts, and improve the appearance of cast parts, safety and functionality. The post-process is called as the deburring process, which is indispensable post process for die casting factories. The burr of the die casting parts in the duration of casting always produces, manufacturers should take some meatures to remove the excess burrs on the suface of cast parts and maintain its fine appearance, safety and proper functionalities. The deburring process is just suitable of treat as cast parts.
Common Deburring Methods In Casting
Die casting parts deburring process
Manual Deburring & Mechanical Deburring Remove the excess material on the surface of die casting parts and Maintain high quality cast parts.
Manual Deburring
This is traditional deburring methods, workers remove the burrs and sharp edges on the surface of die casting parts with handy tools such as grinder, sand media and file. The technique is traditional, flexible and high precision, and suitable for small batch, complex geometries.
Mechanical Deburring
Uses rotating abrasive wheels or belts to grind off burrs. It is suitable for larger, more visible burrs. Using power tools, files to remove burrs and smooth out edges by hand . With abrasive paper or machines, which sand down excess material on the part. Sticking the sandpaper on the rotate wheel, grindering some visible burrs on the part when the wheel rotate.
Thermal Deburring
Uses a combustible gas explosion to burn away fine burrs in hard-to-reach areas. Ideal for small, intricate parts. The burrs on the surface of die casting is so hard that is not easy to be removed. By high temperature, use fire to burn them away from the cast part. The kind of deburring method can offer precision dimensions and perfect appearance of the part.
High-Pressure Water Jet Deburring
Blasts water mixed with abrasives to remove burrs without damaging the part. Under high pressure water and abrasive particles, the burrs on the die cast part are removed and grind the excess area and the flash of casting part line off. maintain a perfect surface finish.
Cryogenic Deburring
.In this process, parts are frozen with liquid nitrogen, making burrs and flash brittle. The brittle burrs are blasted with small, abrasive media. It is suitable for small parts with many hidden burrs. The process is favor of high precision small size die casting parts, change the castable material metal chemical properties. The specific deburring method is suitable for miniature die casting parts, such as cloth accessories.
Laser Deburring
Using focused laser beams to remove burrs without mechanical contact. It can process parts that require a high level of precision and cleanliness. Like in aerospace or medical applications. Ensure that precision tolerance is high.
