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. Please discuss your application with us and we can help guide you to potential solutions for your particular application.

How long will it take to process my order?
It depends on how much effort it takes to process your order, volume of parts, and how complicated the involved tasks are. Generally, we will take 3 to 5 business days to process your order requests. 

Can I have my order in 24 to 48 hours?
Yes, we can give way into our production schedule and put in extra hours to get a rush order for you. We pride ourselves in helping you with meeting critical deadlines. However, it does depend upon the complexity of the part and we do have to recover our additional costs for breaking our production plan and incurring overtime costs.

How much will it cost to process my parts?
We cannot give you a price without a drawing or seeing the actual part. Please give us a call, or use our quote form on the right to submit the required information. 

Why does two parts of approximately the same size have different prices?
The size of the part is only one of 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, masking or bead blasting will result in additional charges.

How do you determine the thickness of a coating?
Coating thickness are usually indicated in the design or it may be stated on a purchase order for a particular part or application. In the absence of a drawing, we will use standard MIL specifications to determine thicknesses for industrial applications.

Will coatings cover scratches, dents and pits on my parts?
Unfortunately not. Many people mistakenly believe that pits, scratches, or other surface defects will be filled in by the anodizing or plating. In fact, any surface defect is likely to become more pronounced after coating.

Can I 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. Used parts generally require additional cleaning and preparation prior to coating. Some defects such as scratches and dents may be removed with additional effort but would need to be discussed so the part is not affected dimensionally relative to your tolerances.

Why are there minimum charges for an order?
There is a minimum cost associated with the processing of your order. These 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, scheduling delivery of your order, and invoicing. Without a minimum charge, we are simply not able to recover these standard costs.

How is anodizing different than plating?
Anodizing changes the surface of aluminum by creating an oxide coating. While building the coating it is also structurally changing the surface of the material. In plating, we are adding additional metal onto an existing metal surface and not changing the surface of the base metal.
