What is the best coating for my parts?
There is no one best coating. The best coating is determined by your application, the functionality of the parts, and the base metal you are trying to coat. BTR-Plating Resources applies a variety of industrial electroplating finishes such as bright nickel-chrome, cadmium, copper, electroless nickel, hard chrome, matte and bright nickel, silver, matte and bright tin, zinc and zinc-nickel alloy to give a corrosion protective outer later to metals, improve electrical conductivity, provide improved wear resistance, reduce friction, improve solder ability, increase part lubricity, to build up the surface area to allow for close tolerance finish grinding and cosmetic appearance. Please discuss your application with us and we can help guide you to potential solutions for your particular application.<back to PLATING>

Why plate parts?
Plating can be used as a base for painting and to improve corrosion or wear resistance. It is also used as a decorative finish on many products including automotive parts, hand tools, plumbing fixtures and a variety of other applications. <back to PLATING>

What is the difference between Electroless and Electrolytic Nickel?
While both processes are depositing a nickel composite on the substrate, electroless nickel uses a chemical catalyst to facilitate the plating reaction as opposed to electrical current.  Part configuration, design application and function are considerations when deciding on which process is recommended. <back to PLATING>

How do you test your plating solutions?
We test our plating solutions daily in our laboratory using titration equipment, hull cells, lab scales, black light and a salt spray cabinet. <back to PLATING>

How do you determine the plating thickness of a specific part?
Plating thicknesses are typically called out in the design or print or a thickness may be stated on a purchase order for a particular part or application. In the absence of a drawing, we will use standard specifications to determine thicknesses for industrial applications or cosmetics in a decorative application. Thickness of plating can be measured in a variety of ways but in the majority of cases we use x-ray fluorescence as this gives us a very precise measurement of plating thickness. <back to PLATING>

How do you test for plating thickness?
Thickness of plating can be measured in a variety of ways but in the majority of cases we use our lab x-ray fluorescence as this gives us a very precise measurement of plating thickness, in the plant we employ magnetic plating measurement devices. <back to PLATING>

Can you plate into a blind bore hole or deep into the I.D. of a part?
Small diameter bores with a depth three (3) times the diameter are partially shielded from the current. Consequently, they will not build up a uniform coating unless internal anodes or cathodes are used. This application is expensive and should be avoided when possible. <back to PLATING>

What about the buildup allowance for threads that require plating?
Threaded areas are tricky in plating and hard coat anodizing. The increase in pitch diameter is at a ratio of 4 to 1. This must be taken into account when designing the threaded parts. When extremely tight thread specifications are involved, it is often necessary to mask the threads. Samples should be processed if your outcome is in doubt.<back to PLATING>

Will plating or coatings cover scratches and pits on my parts?
No. Many people mistakenly believe that pits, scratches, or other surface defects will be filled in by the plating or coating. In fact, any surface defect is likely to become more pronounced after coating.<back to PLATING>

Can I plate or coat my old parts or do the parts need to be new?
Either old parts or newly fabricated parts can be coated. Generally, new parts are easier to coat than old parts. Older or used parts generally require additional cleaning and preparation prior to coating. Also, old parts will have defects such as scratches, dents, pits, etc. that will show up in the finished coating. Some defects may be removed with additional effort but would need to be discussed so the part is not affected dimensionally relative to your tolerances. <back to PLATING>

Are you willing to work with your customers and help develop prototypes?
Absolutely! One of our best attributes is that we work closely with our customers and help them out in all aspects of finishing their parts whether it’s the engineering design phase or suggesting alternative coatings that would be more cost effective.<back to PLATING>

What is powder coat paint?
Powder coat paint is tough, attractive, cost-effective and easy on the environment. It’s a safer, cleaner coating choice that supplies a superior finish. Powder coating is resistant to corrosion, heat, impact, abrasion, fading from sunlight and extreme weather and is available in your choice of colors and textures. <back to PAINT COATINGS>

What is e-coating?
E-Coating is one of the most durable and cost-effective methods of corrosion protection. The E-Coat process involves the use of electrical current to deposit black epoxy paint on material that is then baked in an oven allowing the paint particles to flow into a continuous organic film. This provides total protection by covering recesses, minute holes and other areas inaccessible to conventional spray applications. Not only does e-coat offer protective and cosmetic advantages over other coating methods--it also does so at a reduced cost. <back to PAINT COATINGS>

How do you test for paint adhesion?
Painted parts are tested using the industry’s standard cross-hatch adhesion, pencil hardness test and tape test. For more extensive paint testing we send our parts to PPG industries’ testing laboratory for direct impact, reverse impact, humidity, water immersion, gravelometer, rust spot and throwpower testing. <back to PAINT COATINGS>

Two parts of approximately the same size have different prices, why?
The size of the part is only one the variables that helps determine price. Two parts could be roughly the same size but have very different levels of effort to achieve quality coatings. For example, more intricate parts require special effort to achieve success. Also, any additional steps such as polishing or bead blasting will result in additional charges.

How much will it cost to process my part(s)?
The cost is determined by how much effort it takes to achieve a quality finish that meets functional specifications. We cannot give you a price without a drawing/print or seeing the actual part. The condition of the part is also important along with how intricate the design. Rust, blind holes, small holes, seams, welds, and multiple processes on the same part complicate achieving a quality finish.  Also, where masking or special surface treatment (bead blasted or matte finishes for example) are required, or if additional polishing is requested it takes additional effort. <back to PRICING>

Why are there minimum charges for an order?
There is a minimum cost associated with the processing of your order. Those costs include our incoming inspection, documentation of your requirements and creating the resulting work order, staging your order in our production process, processing your part, quality inspection including thickness measurements as required, scheduling pick-up of your order, and invoicing. Without a minimum charge, we are simply not able to recover these standard costs. <back to PRICING>

What are your payment terms?
Our standard payment terms are net 30 days once your credit is established. New customers may require a check when the order is picked up until credit references are verified. <back to PRICING>
