Color Powder Coating

When you select an engine product or accessory from the Holley Custom Shop to be color powder coated, it comes straight- out-of-the-box brand new, never used. During the powder coating process, painstaking efforts are made to ensure that you receive only a top-quality job. In the end, colors are vibrant and parts are ready to enter a lifetime of service. Here's how important details are to the Custom Shop:

• No other single source can offer you more. If you have the imagination we can help make it reality: Metering blocks are masked off to protect passageways from becoming clogged with any foreign substance.
• Aluminum intake manifolds are bead-blasted with a high-pressure stream of minute glass particles to remove any surface, oxidation, leaving a smooth, bright shine.
• Carbs destined to receive a candy color are first stripped of their original dichromate finish and then placed in a vibratory machine for further cleaning. After inspection, microscopic color particles are statically charged to the metal, producing a clean, uniform finish.
• After being color powder-coated each part is placed in an oven and heated to 350-400 degrees Fahrenheit for 10 minutes. Once the parts have been removed and allowed to cool, they then possess the ability to withstand temps of up to 900 degrees F. This makes them ideal for service in active engines.

Powder coating is not just all show. There really is a practical side to it, which is strength. This high gloss finish helps protect against scuffs and scrapes. It's also virtually impervious to petroleum products such as brake fluid, battery acid, oil and gas, which comes right off with a quick wipe of a shop towel.

Continued exposure to sunlight, too, won't even cause the colors to fade or lose their luster. And above all, these products are completely functional. That leaves you with just one remaining task; Which colors should you choose?

Plating

Sometimes considered the crowning touch in design, plating offers you the chance to complement or draw special attention to one particular area on the product or the whole product itself. Before products are plated, they undergo several buffing and polishing stages to ensure optimum surface smoothness. Extreme care is given with respect to quality, which is maintained by first disassembling the product, such as a carburetor, and then plating the individual pieces. Plating also renders a surface impenetrable to many of the substances in and around an engine. So just what can be plated? Almost anything under the hood, and then some.

Like color powder coating, plating does not interfere with the original design of a part. In fact, it helps by providing extra protection against damage, thus extending the lifetime of the part. Whichever plating you choose, it's sure to be a hit.

Mix 'N Match
Some of the best customized designs on engines are those which use a combination of color powder coating and plating. Plating is a natural complement to color powder coating. In many instances, plating helps highlight or define two colors that would otherwise be right up along side each other. Color powder coating, plating or both. Either way, the choice is yours!
