Custom Acrylic American Mahjong Manufacturing Process: A Complete Guide
Custom acrylic American mahjong gives brands, retailers and game developers control over tile size, thickness, layered construction, colors, face artwork, accessories and packaging.
A set can contain 152, 160 or 166 tiles, or follow a custom tile list approved before sampling. This guide explains the production route for engraved and UV-printed acrylic mahjong tiles, from laminated acrylic sheets to a counted and packed set. It also identifies the product choices and quality checks that should be confirmed before mass production.
Product Overview
Acrylic American mahjong tiles are made from cut and polished PMMA blanks. One- to four-layer structures can be precision engraved and UV color printed with traditional symbols, custom fonts, illustrations, flower tiles, Joker tiles, logos and themed artwork.
Unlike a fixed ready-made set, a custom project requires the tile structure, artwork, number of faces, accessories and packaging to be considered as one complete product. A change in tile thickness or set quantity may also affect the packaging dimensions and inner layout.

Choosing the Right Tile Configuration
Tile Quantity: 152, 160, 166 or Custom
Available configurations include 152, 160 and 166 tiles. A custom set can also follow an approved tile-face list.
The list should identify every symbol and the required quantity, including Jokers, flower tiles, blank tiles and other special faces. A clear tile list helps the production and packing teams check the finished set for missing, repeated or incorrect tiles.
Tile Size and Thickness
Available tile-face sizes include 32 × 23 mm and 36 × 25 mm. Custom dimensions can also be evaluated for specific projects.
Available thicknesses include:
8 mm
10 mm
12 mm
16 mm
18 mm
Custom thickness
Tile size and thickness affect the artwork proportions, layered side profile, complete set volume and packaging dimensions. These specifications should be confirmed before the artwork and packaging structure are finalized.
1-Layer to 4-Layer Acrylic Construction
Custom acrylic American mahjong tiles can use one, two, three or four acrylic layers. Other structures can be evaluated according to the design.
Each layer may add a different color to the side profile. For a multi-layer design, the following information should be confirmed together:
Front acrylic color
Intermediate acrylic colors
Back acrylic color
Layer order
Thickness of each layer
Total tile thickness
These specifications determine which acrylic sheets are laminated at the beginning of production.
Acrylic Color Options
Available acrylic color styles include solid, tortoiseshell, pearl and jelly acrylic.
Solid acrylic creates defined and consistent color blocks. Tortoiseshell acrylic shows decorative pattern variations across the material. Pearl acrylic has a softer pearlescent appearance, while jelly acrylic provides a bright and translucent visual effect.
Different colors can be combined across the layers to match a brand palette, seasonal collection or product theme.
When exact appearance is important, colors should be approved from a physical material reference or sample. Screens, lighting conditions and the natural pattern variation of decorative acrylic sheets can affect how a color appears.
The approved specification should clearly state the color and position of every layer.
Tile Face Artwork and Logo Customization
Tile faces can use familiar American mahjong symbols or custom fonts, illustrations, themes and logos.
Possible customization areas include:
Number and character styles
Joker artwork
Flower tile artwork
Blank tile designs
Seasonal illustrations
Custom back designs
Brand logos
Custom color combinations
Special promotional or event tiles
Buyers should provide an authorized artwork file showing every face and its required quantity. Fine lines, small text and closely spaced details should be reviewed before sampling to confirm that they are suitable for precision engraving and UV printing.
The 9-Step Acrylic Mahjong Tile Manufacturing Process
The following process applies specifically to engraved and UV-printed acrylic mahjong tiles. Material, dimensions, surface condition and artwork are checked at different stages before the tiles are assembled into a complete set.
Step 1 – Acrylic Sheet Lamination
Production begins with the confirmed acrylic colors, layer order and thickness.
The selected sheets are laminated to create the required single-layer or multi-layer structure. For multi-layer tiles, the front, intermediate and back materials must remain in the approved sequence.
The laminated material is checked for the correct color order and a flat, consistent structure before cutting.
Step 2 – Precision Cutting
The laminated acrylic sheets are cut into uniform tile blanks according to the confirmed dimensions.
Consistent cutting provides the starting shape for edge rounding and polishing. The cut blanks are checked for obvious chips, irregular outlines and size differences before moving to the next process.
Step 3 – Wet Tumbling and Edge Rounding
Wet tumbling removes cutting marks and gradually rounds the tile edges.
This process changes the freshly cut acrylic blanks into a smoother tile shape while maintaining the required dimensions. The edge profile, corners and overall tile form are checked after wet tumbling.
Step 4 – Dry Tumbling and Polishing
Dry tumbling further improves the surface smoothness, clarity and gloss of the acrylic tile blanks.
The polished pieces are checked for visible marks, uneven surfaces and inconsistent edge finishing. A clean and uniform blank provides a more suitable surface for the engraving process.
Step 5 – Tile Blank Inspection and Selection
Before engraving, the acrylic tile blanks are sorted and inspected.
Inspection points include:
Tile dimensions
Acrylic color
Layer order
Surface condition
Edge quality
Corner shape
Layered side appearance
Pieces with visible defects or an incorrect structure are separated before entering the decoration stage.
Step 6 – Precision Engraving
The approved tile-face artwork is precision engraved into the polished acrylic surface.
Engraving creates the outlines for numbers, characters, flowers, Jokers and other custom graphics. The engraving position, line clarity and completeness are checked because the engraved areas must align with the UV printing file.
Step 7 – UV Color Printing
Custom graphics and colors are UV printed onto the engraved tile faces and cured during printing.
UV printing can reproduce multi-color symbols, illustrations and brand artwork. The production team checks the print position, color placement, artwork completeness and the correspondence between each printed face and the approved tile list.
Step 8 – Cleaning and Final Inspection
The printed tiles are cleaned and inspected for print clarity, alignment, color placement, surface condition and overall appearance.
Inspectors also check for:
Incorrect tile faces
Missing print areas
Repeated designs
Inconsistent engraving positions
Visible surface marks
Incorrect color placement
The tiles are compared with the approved sample and final tile-face list before set assembly.
Step 9 – Set Assembly and Packaging
The finished tiles are counted and assembled as a 152-tile, 160-tile, 166-tile or custom set.
Jokers, flower tiles, blanks and other special faces are verified against the approved list. The selected accessories are then added, and the complete set is packed in a standard mailer box or custom gift box.
The final check confirms the tile quantity, accessory quantity and packaging configuration.
Accessories for a Complete American Mahjong Set
A custom project can include the mahjong tiles together with different playing, identification and storage accessories.
| Accessory | Use in the Set |
| Dice | Game accessory |
| Mahjong Racks | Organize and display the tiles |
| Pushers | Work with the racks during play |
| Rulebook | Explain the game rules |
| Tile Shuffling Tool | Assist with tile mixing and organization |
| Tile Reference Card | Support tile identification |
| Storage Bag | Store tiles or accessories |
| Wind Indicators | Identify wind positions |
The accessory list should be selected before the packaging is finalized because the quantity and dimensions of the accessories affect the box size and inner layout.
Packaging Options
Standard Mailer Box
A standard mailer box can be used for a straightforward set configuration. The internal space must still match the tile dimensions, total tile quantity and included accessories.
Custom Gift Box
A custom gift box can be developed when the project requires branded graphics, a different box structure or designated positions for the tiles and accessories.
Customizable packaging elements can include:
Box dimensions
Box structure
Exterior colors
Printed graphics
Brand logo
Inner tray
Accessory positions
Product labels
Instruction cards
The packaging dimensions should be confirmed after the tile size, thickness, quantity and accessory list have been approved.
Quality Control for a Complete Mahjong Set
Quality control occurs throughout the production process rather than only after packaging.
Material and layer order are reviewed before cutting. Dimensions, edges and surfaces are checked after tumbling and polishing. Engraving and UV printing are compared with the approved artwork. The complete set is counted before packing.
Final inspection covers:
Tile dimensions and thickness
Acrylic color and layer order
Edge and corner finishing
Surface appearance
Engraving position
UV print alignment
Color placement
Missing tile faces
Repeated tile faces
Total tile quantity
Accessory quantity
Packaging configuration
The approved physical sample, artwork and tile-face list provide the main references for production and final inspection.
MOQ, Sampling and Production Time
The minimum order quantity is 300 sets.
Sample production normally takes 7–10 days, and mass production normally takes 30–35 days.
Production timing is evaluated according to the confirmed design, materials, tile structure, accessories, packaging and order quantity. Changes to the artwork, thickness, layer order or packaging after approval may require a revised evaluation.

FAQ
What artwork format should I prepare for a custom mahjong project?
Editable vector artwork is preferred because it allows the engraving lines, printing areas and individual tile faces to be checked clearly. The file should separate each design and identify the required quantity. If only image files are available, their resolution and suitability should be reviewed before sampling.
How should I organize a custom tile-face list?
Create a table or numbered list showing the artwork name, file reference and required quantity for every face. Jokers, flowers, blanks and special promotional tiles should be listed separately. The total of all individual quantities should match the required set quantity.
What happens if the artwork contains very small text or fine lines?
Fine details may need to be adjusted before sampling so the engraved outline and UV-printed color remain clear. The artwork should be reviewed at the actual tile size rather than only on a large computer screen. Any recommended adjustment should be confirmed before the sample is produced.
Can the design be changed after the sample has been approved?
The artwork, material colors, tile structure or packaging can be revised, but changes made after sample approval may require a new sample or production evaluation. A change in material thickness can also affect the tile appearance and packaging dimensions.
How should a physical sample be reviewed?
Review the complete set rather than checking only one attractive tile. Confirm the size, thickness, layer order, colors, artwork position, UV printing, edge shape, tile-face quantities, accessories and packaging. Record all requested changes together to avoid conflicting revision instructions.
How can repeat orders remain consistent with an earlier order?
Keep the approved sample, material references, artwork files and packaging specifications as the basis for repeat production. Decorative materials such as tortoiseshell acrylic may show natural pattern variation, so the required matching standard should be discussed before a repeat order begins.
What information most commonly delays sampling?
Sampling can be delayed when the tile-face list is incomplete, artwork quantities do not match the total set count, layer colors are not identified, or packaging and accessories remain undecided. Providing one final artwork version and one confirmed specification list helps the project move forward more efficiently.
Who is responsible for the rights to custom artwork and logos?
The buyer should provide artwork, logos, fonts and illustrations that it owns or is authorized to use. Authorization should be confirmed before the files enter sampling or production, particularly for branded, licensed or character-based designs.
