Metal Finishes
KenWalt Die Casting offers a full range of metal finishes to improve aluminum and zinc casting’s look, strength, and performance. Whether your part needs to stand up to heat, moisture, or wear—or simply look spectacular—our finishing options help it do the job. From polished consumer goods to rugged industrial parts, we match each finish to your application’s demands.
Our in-house and trusted partner processes support everything from ice cream scoops with a polished shine to automotive and aerospace parts built to last.
We apply the right finish based on how your part will be used. Some finishes help protect against rust or wear. Others are chosen to give parts a clean or high-end look. In many cases, a good finish can do both.
Powder Coating
- Powder coating adds a tough, even surface to your part. It protects against scratches, corrosion, and fading. Powder-coated parts also come in many colors and textures. We often use this finish on parts for vehicles, electronics, and industrial tools. It holds up well in outdoor or high-use settings.
Chrome Plating
- Chrome plating gives parts a smooth, shiny look—similar to polished steel or mirror-finished aluminum. It also adds a layer of protection against wear and corrosion. This is a popular option for visible consumer parts and decorative hardware.
Sandblasting
- Sandblasting uses fine grit to smooth or clean a part’s surface. It removes debris or sharp edges and creates a consistent, matte finish. This is often done before coating or plating to help those finishes stick better. It also works as a standalone finish when a textured surface is preferred.
Anodizing
- Anodizing is used for aluminum parts. It changes the surface of the metal so it resists corrosion and wear. It can also be colored for visual appeal. Anodizing is common in aerospace, electronics, and medical parts where appearance and durability matter.
Chem Film
- Also known as chromate conversion coating, chem film protects aluminum parts without changing their size or shape. It improves corrosion resistance and helps paint or powder coat stick. It’s often used in aerospace, defense, and marine applications where lightweight metals need reliable protection.
Ball Burnishing
- Ball burnishing polishes the surface of a part using small steel balls. This process gives the casting a clean, shiny finish—similar to chrome or polished aluminum. It’s often used on parts like fishing lures or kitchen tools, where the surface must be smooth and eye-catching.
Why Finishing Matters
A good finish does more than improve a part’s appearance. It also protects it from damage. Metal parts often face moisture, friction, or chemicals during use, so a strong finish helps them last longer.
KenWalt finishes:
- Prevent rust and corrosion
- Protect against scratches and impact
- Improve part appearance
- Create smoother edges and surfaces
- Make coatings or adhesives stick better.
We work with parts of all sizes, from small consumer items to large-scale housings for electric vehicles, defense systems, and heavy-duty equipment.
