Diverse Product Types to Attract Your Customers

We offer sublimation aluminum blanks in many styles and finishes. By stocking different varieties, you can easily meet the needs of diverse customer segments.

White Gloss Sublimation Sheets

White Matte Sublimation Sheets

Brushed Silver and Gold Aluminum Blanks

Note: Because there is no white base, any white areas in your original digital image will appear as raw silver or gold metal on the finished print.

Mirror Finish Sublimation Aluminum

Pre-Cut Sublimation Blanks

To save you production time and labor, we supply pre-cut blanks in standard market sizes. These blanks feature clean, de-burred edges and rounded corners to prevent cuts during handling.

License Plate Blanks

Our sublimation license plates are cut to the standard size of 300 mm×150 mm (for US cars) or 520 mm×110 mm (for EU standards). They are usually made of Alloy 3003−H14 with a thickness of t=0.8 mm or t=1.0 mm. They come with four pre-slotted mounting holes for fast installation.

Metal Business Cards

These are premium blanks cut to the exact size of 85.6 mm×54 mm. They are very thin (t=0.2 mm to t=0.3 mm) so they remain lightweight and flexible. We round the corners to a small radius (r=3.0 mm) so they slip into wallets smoothly without snagging.

Sign Board Blanks

We supply flat sign boards in common dimensions like 200 mm×300 mm and 300 mm×400 mm. These are ideal for fire escape paths, private property notices, parking directions, and retail displays.

Photo Panel Blanks

Our photo panels are manufactured with a thicker aluminum substrate (t=1.15 mm) to prevent bending. They are available in large wall art sizes like 400 mm×600 mm and 600 mm×900 mm. They can be ordered with special wooden or metal hanging blocks attached to the back, creating a floating effect on walls.

Step-by-Step Guide to Printing on Aluminum Blanks

To get perfect, vibrant prints with zero defects, you must control your temperature, time, and pressure carefully.

Temperature and Time Recommendations

Below is a general reference table for sublimating onto aluminum. Actual settings may vary slightly based on your specific heat press model and the thickness of the metal sheet.

Thickness (t)	Heat Press Temp	Pressing Time	Pressure Level
0.22 mm−0.35 mm	180∘C−185∘C	40−50 seconds	Medium (3−4 bar)
0.45 mm−0.70 mm	185∘C−190∘C	50−70 seconds	Medium (3−4 bar)
0.80 mm−1.15 mm	190∘C−195∘C	70−95 seconds	Medium to Hard (4−5 bar)
1.50 mm−2.00 mm	195∘C−200∘C	100−130 seconds	Hard (5 bar)

Important Processing Tips

To avoid costly production mistakes, always keep these three simple rules in mind:

1. Peel the Protective Film First: Every blank comes with a thin clear or blue protective plastic film. This film prevents scratches during shipping. You must peel this film off before putting the metal in your heat press. If you forget, the plastic will melt onto your heater or the sheet and ruin the blank.
2. Avoid Overheating: If you press the metal for too long or at a temperature that is too high, the polyester coating can turn yellow or bubble. This will ruin the clarity of your print.
3. Use Thermal Tape: Use heat-resistant thermal tape to secure your sublimation paper firmly to the aluminum blank. If the paper moves when you open or close the press, it will create a double image, commonly known as “ghosting.”

Sublimation Aluminum Metal Sheets and Blanks Frequently Asked Questions (FAQ)

Here are the answers to the questions our customers ask most frequently.

What is the ideal temperature for sublimation printing on aluminum?

The ideal sublimation temperature is generally between 180∘C and 200∘C. Thinner blanks require lower heat and shorter pressing times to prevent the coating from burning. Thicker blanks require higher heat and longer pressing times because the thick metal absorbs more heat before the polyester coating reaches the correct activation temperature.

Do I need to peel off the plastic film before printing?

Yes, absolutely. The thin PE (polyethylene) film is applied solely to protect the smooth finish during manufacturing, cutting, and shipping. It is not heat-resistant. If you place the sheet in the heat press with this film still attached, it will melt, ruin the coating, and release toxic fumes.

Can sublimation aluminum sheets be cut after printing?

Yes, you can cut thin aluminum sheets after they are printed. Use sharp hand shears, a heavy-duty paper cutter, or a professional corner rounder. However, you should work carefully to avoid scratching the printed surface. For thicker sheets (t≥1.0 mm), we strongly recommend buying pre-cut blanks. Cutting thick aluminum post-print can stress the polyester coating, causing it to chip or peel along the cut edges.

Are sublimated aluminum sheets suitable for long-term outdoor use?

This depends on the coating. Standard sublimation coatings are designed for indoor use. They can fade within 6 to 12 months if exposed to strong, direct sunlight. These protective coatings contain chemical UV-inhibitors that can preserve the colors for years.

What causes blurry prints on aluminum sheets?

Blurry prints or double images are usually caused by paper shifting during the sublimation process. When the hot gaseous ink transfers to the polymer, any slight movement of the paper results in a shadow effect. Always secure your sublimation transfer paper tightly to the metal blank using heat-resistant thermal tape. Also, open your heat press gently to avoid pulling the paper with suction.

How should I store unprinted sublimation sheets?

Store your unprinted aluminum sheets in a cool, dry, and dust-free room. Keep them stored completely flat. Storing them upright against a wall for long periods can cause the sheets to warp slightly. Always keep the protective plastic film on the metal until you are ready to place them in the printing press. This prevents dust and fingerprints from contaminating the sublimation surface.
