Frequently Asked Questions
What Lead Times Should I Expect for Anodizing?
There are many factors that influence the time it takes to receive your order, including the specifications and the factory’s capacity. The most influential factor will often be the shipping method you choose, which in most cases takes longer than the actual production schedule. When you choose air service, delivery will usually take place within about a week of order completion. If you choose sea transportation, your items may take up to six weeks to arrive. You’ll be able to view all of this information clearly on the proposals you receive.
What Standards Do Aluminum Anodizing Suppliers Work To?
Verified factories on our platform primarily operate under ISO 9001 standards, with many also holding additional certifications such as IATF 16949 or AS 9100. It’s also common for anodizing manufacturers to comply with MIL-A-8625, ASTM B117, and ASTM D3359, while meeting any additional specifications you provide. Within your RFQ, you can list your exact certification requirements, and only suppliers that meet those compliance standards will be able to apply.
How Do I Protect Design Files When Working With Anodizing Suppliers?
Haizol offers several tiers of confidentiality depending on your project needs. For open designs, a nondisclosure agreement (NDA) is optional. For proprietary or sensitive designs, you can seal your files behind mandatory NDAs, which can be provided by you or generated through our platform. Only factories that have signed the NDA will be granted access to your protected information.
How Do You Choose Anodizing Companies for Aluminum Parts?
Anodizing companies should be matched to aluminum alloy, anodizing type, color, thickness, sealing method, cosmetic standard, masking needs, and inspection requirement. For custom aluminum parts, the factory profile helps confirm whether the finishing shop is suited to machined, extruded, cosmetic, or hard-anodized work.
What Is the Difference Between Standard Anodizing and Hard Anodizing?
Standard anodizing is often used for corrosion resistance, appearance, and color on aluminum parts. Hard anodizing creates a thicker, harder oxide layer for wear resistance and more demanding service conditions. To compare factories fairly, specify the anodizing type, target thickness, color, sealing, and inspection standard.
What Should an Anodizing Quote Request Include?
For anodizing, start with the aluminum alloy because different alloys finish differently. Add the part drawing, anodizing type, color, coating thickness, masking areas, cosmetic requirements, quantity, and inspection standard. If the part is machined or extruded, include surface roughness expectations before finishing.
