Production in 15–20 days

These are the three buyer-side gates. For the detailed factory process behind each order, see our manufacturing process page.

Choose the Sample That Answers the Buying Question

A sample should close a named risk before production. We quote the smallest sample scope that can prove the material, appearance, fit, construction or packout decision holding up the order. Every physical sample is paid separately and never credited to production.

Level 1

Material or artwork proof

Use a sheet coupon, color target or printed proof when the open decision is appearance rather than full assembly.

Level 2

Fit or process sample

Use a representative part when the decision is slot clearance, mating geometry, edge finish, printing or engraving.

Level 3

Production-intent sample

Use one finished unit with the approved material, construction, branding and packing when the complete product must be signed off.

What you receive: the agreed physical sample, process or artwork confirmation, approval photos or video before dispatch, and a recorded revision for the production file.

Timing: standard tile samples normally take 5–7 days after the brief and payment are approved. Full set samples and multi-material programs are quoted separately.

After approval: the released sample and files become the production reference. Standard production normally takes 15–20 days after approval.

Materials We Work With

Cast acrylic (PMMA) is the usual starting material for our fabrication work. We quote clear, colored, frosted, mirrored and specialty sheets by named grade and supplier availability. When a project requires a brand-color match, the quote and approval record identify the physical target, sheet grade, print method and viewing conditions.

Cast PMMA sheet used for custom mahjong tile bodies

Clear

Transparent sheet for products where visibility and edge appearance matter; the selected grade is named in the quote.

Typical use: clear tile bodies, case walls, pushers

Colored cast PMMA sheets used for mahjong tile colorways

Colored

Standard colors plus custom brand-color matching against an approved physical sample.

Typical use: brand-color tile sets, colored racks and pushers

Frosted acrylic mahjong tile face detail

Frosted

Diffused or matte appearance approved against a named sheet and physical sample.

Typical use: frosted tile backs, diffused case panels

Mirrored acrylic sheet option for custom mahjong tiles

Mirrored

Reflective surface, lightweight alternative to glass mirrors.

Typical use: mirror-accent case lids, retail display bases

Glitter acrylic option for custom mahjong tile blanks

Glitter

Embedded sparkle particles for eye-catching visual effects.

Typical use: boutique-edition tiles, gift-set accents

UV-Filtering

Specialty grades are available for projects that need reduced UV exposure; wavelength performance is confirmed from the selected sheet's supplier data.

Typical use: long-term display cases, club display walls

Why Customization Works Better Under One Roof

USMJ runs cutting, CNC machining, polishing, bending, printing, assembly and inspection in one 3,000 m² Shenzhen facility with 50+ staff. One released file set can therefore control the drawing, artwork, sample, production and inspection record without passing the specification between unrelated suppliers.

FactorOutsourced ModelUSMJ In-House
CommunicationYou → Factory → Subcontractor → Factory → YouYou → USMJ (one contact, one thread)
Sample SpeedDepends on the schedules and handoff rules of each supplierStandard paid tile sample target: 5–7 days after approval
Quality ControlDifferent standards at each stopIn-house process and project records under one documented quality system; verify the requested scope with the quality-control checklist
Design ChangesChange one parameter → re-coordinate with all subcontractorsOne revision record can be reviewed across the affected processes
Cost StructureEach supplier quotes its own scope and handoffOne quote identifies material, process, setup, packing and shipping scope

What to verify in a supplier audit

Ask who owns the released drawing, where each process is performed, how revisions reach the floor, what the sample approves, and which inspection record will travel with the order. The quality-control checklist turns those questions into an evidence request.

What Drives Custom Mahjong Tile Pricing?

Six factors determine a custom fabrication quote: size, material, quantity, finishing, complexity and packaging. The price is calculated against the released specification, so the quote can show which input moves the number.

Size & Dimensions

Material use changes with the finished envelope, sheet layout, thickness and whether the product is cut as one part or assembled from several panels.

Material Type

Clear cast acrylic is the baseline. Colored, frosted, mirrored, and UV-filtering sheets carry supplier- and grade-specific premiums, which we identify in the material line of the quote.

Order Quantity

The biggest single cost lever. Programming and setup costs spread across more units. At the 50-set production floor, setup is a meaningful part of unit cost; at 500 sets it is much smaller. Published FOB Shenzhen references for a standard-spec engraved set are $58 at 50 sets, $56 at 100, $50 at 200, $49 at 250, and $47 at 500. Reference only · FOB Shenzhen · confirmed on your written quote.

Finishing & Branding

Artwork, color count, print coverage, proofing, edge route and visible-surface requirements determine the quoted finishing setup and unit work.

Structural Complexity

Part count, bonding, formed geometry, hardware pockets, fit checks and inspection scope determine the production sequence and labor in the quote.

Packaging & Shipping

Bulk packing, retail boxes, foam inserts, labels and pallet requirements are quoted against the final packout. FOB Shenzhen and DDP can be shown as separate scopes for factory-price and landed-cost review.

Frequently Asked Questions

Can I order custom mahjong tiles without a CAD file?

Yes. Start with a sketch, reference photo or rough description. Add dimensions, quantity, material preference and branding details. Our engineering team creates a production drawing for approval before fabrication begins. If you already have production CAD, send DXF for flat profiles and STEP for 3D geometry, and mark the controlling dimensions.

Can I change the design after approving a sample?

Yes, before bulk production begins. A change to dimensions, material, artwork, construction, fit or appearance may require a revised drawing, proof or paid sample. We identify the revised scope, timing and any setup charge before work resumes, then release production only after written approval.

What if the quote comes in over my budget?

Tell us your target price and we will show which specification inputs move the number. Common review points include material thickness where the structure allows it, part count, print route, quantity tier and packing scope. Every approved change remains visible in the revised quote and drawing.

Does the 50-set MOQ apply per design, or across my whole order?

MOQ is 50 sets per tile design. A different printed artwork, shape, or size counts as a separate design, so quantities do not combine to clear the production floor. Accessory customization starts at 250 sets and custom packaging at 1,000 sets. UV printing avoids screen plates and keeps artwork-change setup lower, but each design still needs its own production run. Use a paid sample to validate secondary designs before committing.

Can I get pricing before my artwork and dimensions are final?

Yes. Send a reference photo, target tile size range and the quantity tiers under review. We can return an estimate against stated assumptions and identify which inputs still control the number. Final pricing is confirmed against the released dimensions, material, construction, artwork, packing and destination before sample production.

Can you help me choose between material options (clear vs frosted vs colored) for my mahjong tiles?

Yes. We compare visibility, surface appearance, color target, cleaning method, structural need and supplier availability before naming the material in the quote. If the decision is visual, request sample comparisons in the top two options before bulk production. More ordering questions about sample fees, payment, shipping and tolerances are answered on our full FAQ page.

What information do you need to quote a personalized mahjong set?

Send the controlled dimensions, quantity per design, application, material or appearance target, critical tolerances, print or engraving artwork, assembly requirements, packaging, and destination. A sketch or reference photo is enough to start when you label the dimensions and identify what must fit, move, or align.

Can I put my logo on the tile backs or design my own Joker tiles?

Yes. Tile-back logos are laser-engraved or UV-printed at a fixed position and depth across the whole set, and custom Joker tiles are UV-printed from your outlined vector artwork and sealed with a clear coat. Both are checked on the paid sample, and personalized mahjong sets start at 50 sets per design.

How should I specify tolerances and critical dimensions?

Mark the dimensions that control fit, alignment, movement, or mating parts and state the acceptable range for each. Do not apply one tight tolerance to the whole drawing. We review whether the requested tolerance matches the process and confirm the inspection method before sampling.

Can I approve a paid prototype before the production MOQ?

Yes. A paid tile sample normally takes 5–7 days after the drawing and artwork are approved. Use it to check dimensions, fit, color, print, surface finish, assembly, and packaging; the production run begins only after written sample approval and the agreed payment gate. The sample program lists the release records to carry into bulk production.

Does USMJ provide full industrial design services?

No. We provide design-for-manufacture review, production drawings, material and process recommendations, and revisions needed to make a defined product buildable. Product strategy, user research, industrial-design concept development, certification design, and ownership of the product brief remain with the buyer or their designer.

Which approved file controls custom mahjong tile production?

The released production drawing and artwork revision control cutting, machining, print position, assembly, and inspection. If a later file changes a dimension, material, construction, or visual requirement, we issue a revised approval set and assess whether another paid sample is needed before production.
