What Is Sand Blasting Service For Die Castings

Sand Blasting Service for die castings is an abrasive cleaning process that removes contaminants, roughens surfaces, and enhances the texture of die-cast parts. It prepares components for further processing, such as coating or painting, improving adhesion and final appearance.

Steps	Description
Surface Preparation	The process begins with preparing the die-cast parts by cleaning them thoroughly. Sand blasting removes dirt, oil, rust, and other contaminants, ensuring the part’s surface is ready for further processing, coating, or painting.
Abrasive Application	During sand blasting, abrasive particles, typically sand or other media, are propelled at high speed towards the part’s surface. The force of the abrasives helps clean, smooth, and texture the part’s exterior.
Surface Roughening	Sand blasting creates a roughened surface, increasing the surface area and promoting stronger adhesion for coatings like paint or anodizing. This improves the durability of the final finish, ensuring longer-lasting protection.
Final Inspection & Quality Control	After sand blasting, the parts are inspected to ensure the desired texture, cleanliness, and surface finish are achieved. This final check guarantees that the die-cast parts meet customer specifications and are ready for subsequent processes or assembly.

Properties of Sand Blasting

Sand blasting is a surface treatment process used for cleaning, texturing, or preparing parts for further coating. It works on metals, plastics, ceramics, and glass, providing matte to textured finishes with surface roughness (Ra 3.2 - 6.3 µm). It improves corrosion resistance when combined with coatings, offers moderate wear resistance, and is cost-effective and fast.

Property	Description
Material Compatibility	Metals, plastics, ceramics, glass

Thickness	Does not apply; surface treatment process

Color Options	Dependent on material (no color change unless coated afterwards)

Texture Options	Matte, rough, satin, or textured finish

Surface Finish	Ra 3.2 - 6.3 µm (depends on blasting media and material)

Hardness	No direct effect on hardness; can be used for cleaning or surface prep

Corrosion Resistance	Improves corrosion resistance when combined with coatings or sealants

Environmental Resistance	Moderate, dependent on coating or additional surface treatment

Electrical Insulation	Can help prep parts for coating that provides electrical insulation

Wear Resistance	Moderate (depends on material and coating applied after blasting)

Applications	Surface cleaning, deburring, etching, preparation for coatings

Cost	Low to moderate (depending on media used and part size)

Time	Fast (depending on part size and complexity)
