Surface Treatments for Automotive Casting Parts

KEMING’s expertise in diverse casting methods and surface treatments allows automotive manufacturers to select finishes tailored to the performance, aesthetic, and durability needs of their cast components. Sandblasting and electro-galvanizing offer robust, protective finishes for functional parts, while precision and shell mold casting paired with polishing or chemical treatments deliver high-quality surfaces for consumer-facing components. This flexibility ensures that KEMING can meet the stringent requirements of automotive applications across the board.

Sandblasting and Shot Blasting for Surface Preparation and Uniform Texture

KEMING provides sandblast and shot blast surface treatments, which are excellent for removing surface scales and preparing castings for further finishing. These methods create a uniform matte texture that improves paint or coating adhesion and enhances corrosion resistance.

Electro-Galvanizing and Anti-Rust Oil Paint for Corrosion Protection

KEMING offers electro-galvanized coatings and anti-rust oil paint finishes, which are crucial for automotive castings exposed to harsh environments. These finishes extend the lifespan of components by preventing rust and corrosion.

Building High-Quality Consumer Grade Parts with Post-Casting Finishing

KEMING’s precision casting combined with machining and polishing can achieve smooth, burr-free surfaces suitable for decorative or visible automotive components. This approach supports consumer-grade finishes where appearance and tight tolerances are critical.

FAQs About Automotive Castings

What are automotive castings?

Automotive castings are metal components used in vehicles, produced by pouring molten metal into molds to form parts with specific shapes and dimensions. This process allows for the creation of complex, precise parts with minimal material waste, essential for various automotive components such as engine blocks, transmission housings, and suspension parts.

Typical cast parts include engine blocks, transmission housings, suspension components, steering knuckles, brake calipers, intake and exhaust manifolds, turbocharger parts, and structural elements. These parts benefit from casting’s strength, durability, and precision.

Materials are chosen based on strength, weight, durability, and performance needs. Typical materials used for automotive castings include aluminum alloys, cast iron, steel, zinc alloys, and magnesium alloys. Aluminum is favored for its lightweight, corrosion resistance, and good thermal conductivity, making it ideal for engine blocks, wheels, and transmission cases. Cast iron, especially gray and ductile iron, is used for engine blocks and brake components due to its wear resistance and vibration damping. Steel castings provide high strength and toughness for structural parts.

KEMING quality control in automotive castings involves multiple techniques: visual inspection to detect surface defects; dimensional inspection using tools like CMMs and laser scanning to ensure precise measurements; and non-destructive testing (NDT) methods such as X-ray, ultrasonic, and magnetic particle testing to find internal flaws. Additionally, mechanical property tests (hardness, tensile strength) and process controls monitor casting parameters to prevent defects. Statistical process control (SPC) is also used to maintain consistent quality throughout production.

Automotive casting finishing operations by KEMING include removing excess material such as runners and risers using band saws or chop saws, deburring to eliminate sharp edges and flash, and fettling for cleaning parting lines. Surface treatments like shot blasting, grinding, sanding, and polishing improve appearance and dimensional accuracy. Additional finishes include powder coating, painting, anodizing, plating, and conversion coatings to enhance corrosion resistance, wear resistance, and aesthetics.

The typical production lead time for Keming Automotive Casting, specifically for investment casting, is around 35 days after sample approval for mass production. This includes multiple stages such as mold making, casting, and post-processing to ensure quality and precision. Peak season lead time for casting parts can be within 15 workdays, depending on order volume and complexity.
