Die Casting Surface Finishing

shot blasting and surface finishing equipment for die casting parts

Die casting surface finishing prepares aluminum and zinc alloy parts for appearance inspection, painting, coating, assembly or shipment. The process can include trimming, deburring, polishing, shot blasting, cleaning and surface preparation depending on part structure and customer requirements.

Surface finishing should be confirmed before quotation because it affects cost, lead time, inspection standards and packing. Buyers should define visible surfaces, burr limits, coating requirements, color standard and whether any area must be protected during finishing.
