Deburring on die castings is essential for the rough cast parts. The burrs on die castings means excess sharp edges on the cast parts, flash on the partline of die casting parts and hidden residues on the cast parts. As the rough die casting parts, burrs are exisited on the cast parts is normal, so the post-processing for cast parts is indispensable. To want t remove these excess material on the cast parts and make the surface of die castings more smooth and being convenient to treated for further surface finishing process, deburring on die castings are necessary.
What Are Deburring On Die Castings ?
Deburring on die castings means removing excess sharp edges on the cast parts and flash on the partline of die casting parts, and effectively improve the appearance of cast parts, safety and functionality. The post-process is 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. Various Deburring methods on die castings plays their unique role in Deburring process.
Common Deburring On Die Castings Methods
Die Casting Parts Deburring Methods
Manual Deburring & Mechanical Deburring Remove the excess material on the surface of die casting parts and Maintain high quality cast parts.
Mechanical Deburring
Uses vibrative machine to remove the gate gap on the die casting part. It is suitable for any die casting part. Using high frequency shakes actions makes the large gate gap is separated from the as cast part completely. It needs custom clamping tools and jigs and fixed the die casting part on the clamp tool. It is high efficiency and cost-effective. operator run the vibrative machine high frequency start the machine.
Manual Deburring
This is one of traditional deburrings on die castings, 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 and flexible processing action.
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 at supper low temperature, become burrs and flash brittle. then put the frozen metal parts into shot-blasering oven and hit these hidden and excess material on the cast parts. 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 in accuracy, make the cast parts more smooth surface. The process is cleanness, without any dust, like some high precision metal parts in aerospace or medical applications. The focused laser beam can accurately cut the burrs and clear residues on the surface of die casting part and maintain a clean and tidy appearance.
