7.FAQ

What are the advantages of aluminum alloy shell compared to plastic shell?

Aluminum alloy shell has the following core advantages:

High strength and drop resistance: better impact resistance than plastic, protecting the internal battery safety;

Efficient heat dissipation: metal has good thermal conductivity, reducing the risk of high temperature of the battery;

High-grade texture: anodized surface treatment is wear-resistant and anti-fingerprint, improving the product grade;

Environmentally friendly and durable: recyclable material, life is far longer than plastic shell.

What information do I need to provide for custom aluminum alloy shell?

You need to provide the 3D design drawings of the shell, size requirements (length/width/height/wall thickness), interface types (such as Type-C, USB-A, etc., quantity and location), surface treatment process requirements (such as anodizing color, laser engraving content), and relevant certification requirements (such as CE, RoHS, etc.). If there is no design drawing, we can provide professional design support.

Do you support small batch customization? What is the minimum order quantity (MOQ)?

Support small batch customization, MOQ is usually 100-500 pieces (adjusted according to the complexity of the design), which can flexibly meet the needs of start-up brands or test markets.

Do you provide global logistics services? How to calculate the freight?

Support global delivery (DHL/FedEx/sea freight, etc.), freight is calculated in real time according to the quantity and destination, and bulk orders can be negotiated for free shipping or CIF.
