1. Strict Supplier & Raw Material Screening
At FENGZHE MFG., quality begins with the selection of acrylic sheets suitable for premium American Mahjong production. Before materials enter our manufacturing process, we review their visual clarity, color appearance, surface condition and suitability for the approved tile design. Our aim is to identify material-related issues early and establish a reliable foundation for precision cutting, engraving and layered construction.
Different Mahjong collections require different material characteristics. Transparent and translucent designs call for careful attention to light transmission and visible inclusions, while multi-layer tiles require consistent sheet thickness, color coordination and clean bonding surfaces. Our team evaluates these practical requirements against the customer-approved sample and project specifications before scheduling production.
Incoming sheets are checked for obvious scratches, uneven coloring, edge damage and other visible imperfections. Materials that do not meet the agreed requirements are separated for review rather than automatically released to production. Where specific material documentation or independent testing is needed, we discuss the appropriate scope with the customer and only present verified information relevant to the actual order.
2. Pre-Production Sample Validation & Confirmation
Before bulk production begins, we review customer-provided drawings, artwork and design requirements to prepare a physical sample for evaluation. Our team considers tile dimensions, layered acrylic construction, engraving details, surface finishes and packaging expectations during sample development.
The sample is reviewed for visual appearance, dimensional accuracy and overall presentation. Key details such as color consistency, edge smoothness, engraving alignment and the fit of individual components can be discussed and adjusted according to the approved specifications.
Once the customer confirms the sample, it serves as an important reference for the production order. Any later design changes are reviewed before implementation to help maintain consistency between the agreed design and the finished Mahjong collection.
3. Finished Mahjong Tile Inspection
Before finished Mahjong tiles proceed to packing, we review their appearance, dimensions and workmanship against the approved sample and the specifications agreed for each order. Our inspection approach focuses on the details that influence presentation, durability and handling.
(1) Dimensions & Uniformity: Tile length, width, thickness and overall consistency are checked against the approved specifications.
(2) Edges & Polishing: Edges and corners are reviewed for smoothness, chips, burrs and uneven polishing.
(3) Artwork & Surface Finish: Engraving placement, printed patterns, color application and visible surface defects are examined.
(4) Layer Alignment: For multi-layer acrylic tiles, we check visible alignment, layer consistency and the finished appearance.
(5) Set Configuration: Tile quantities, design assortment and accessories are checked against the confirmed order configuration.
(6) Overall Appearance: We review the visual consistency of the completed tiles and identify items requiring rework or further inspection.
Products that do not meet the agreed inspection criteria are set aside for review, correction or replacement as appropriate. Inspection scope and sampling arrangements are confirmed for each production order.
4. On-Site Quality Audit for Finished Mahjong Sets
After assembly and surface finishing, completed American Mahjong sets are reviewed at designated quality checkpoints. Our team examines appearance, tile matching, protective packaging and order-specific details before finished goods are released for dispatch. The inspection scope is confirmed for each production order.
(1) Surface appearance: review acrylic faces and edges for visible scratches, dust, residue, chips or uneven polishing.
(2) Set assembly: examine the fit and alignment of layered tiles, accessories and packaging components against the approved sample.
(3) Color and artwork: compare engraving, printed designs and tile colors with the customer-approved references.
(4) Packaging protection: confirm that inserts, wrapping and outer packaging are suitable for the approved product configuration.
(5) Dimensional review: check selected tile measurements and overall consistency against agreed tolerances and inspection requirements.
Products requiring additional attention are separated for review, correction or replacement as appropriate. Our objective is to identify visible and assembly-related issues before packing and to maintain a clear reference to the approved product specifications.
5. Final Product Inspection & Pre-Shipment Batch Review
Step 1: Final Finished Goods Inspection
After production and assembly, finished Mahjong tiles and accessories are reviewed against the approved sample and agreed order specifications. Our final checks focus on product appearance, design accuracy, component fit and packaging readiness before goods are prepared for shipment.
Surface review: examine tiles for visible scratches, dust, residue and irregular finishes.
Artwork and color: compare printed or engraved designs with approved artwork and color references.
Construction: assess acrylic layer alignment, edge finishing and the stability of assembled components.
Set completeness: confirm tile quantities, accessories and presentation details against the approved packing list.
Items that do not meet the agreed acceptance criteria are identified for further review or corrective action before release. Inspection coverage and any sampling requirements are determined for each order.
Step 2: Pre-Shipment Batch Verification
Before dispatch, our team reviews the finished order against the approved packing plan. Carton quantities, product variants, protective inserts and shipment labels are checked to support accurate fulfillment and careful handling in transit.
Order records are compared with the prepared cartons, including item descriptions, quantities and shipping marks. Export documents and destination-specific information are coordinated according to the shipment and customer requirements.
If damaged packaging, inconsistent quantities or other discrepancies are found, the affected cartons are set aside for clarification and correction before dispatch. The team can discuss additional inspection arrangements when required by the customer.
Our goal is to deliver clearly identified, well-protected custom Mahjong collections with organized shipment records and consistent communication throughout the handover process.
6. Full After-Sales Quality Support
Quality support does not end when an order leaves our facility. FENGZHE MFG. works with wholesale partners to review reported product concerns, understand their impact and identify practical next steps. Our after-sales approach emphasizes clear documentation, responsive communication and case-by-case solutions.
(1) Report a concern: Please contact our team with your order number and clear photographs of the outer cartons, inner packaging and affected Mahjong tiles or accessories. Sharing the quantity involved and a description of the issue helps us review the case.
(2) Quality review: We compare the reported issue with the approved sample, agreed product specifications and available production or inspection records. Where needed, our team may request additional details to understand the cause.
(3) Resolution planning: Depending on the findings and the agreed order terms, we discuss suitable remedies such as replacement components, rework, additional production or other mutually accepted arrangements. Timing and shipping responsibilities are confirmed for each case.
(4) Continuous improvement: Feedback from each reviewed issue helps us refine material checks, workmanship standards, packing methods and inspection instructions for future custom Mahjong orders.
Why Our Full-Cycle Quality Control Matters
Custom American Mahjong requires more than an attractive finished appearance. Material clarity, tile dimensions, layered construction, engraved artwork, color matching and packaging must work together to deliver a consistent product experience. Reviewing these details across multiple stages helps us identify potential issues earlier.
By connecting material screening, sample confirmation, production checks, final inspection and after-sales feedback, FENGZHE MFG. supports clearer expectations and more dependable collaboration with brands, retailers and wholesale distributors. Our goal is to help partners build distinctive Mahjong collections with confidence.
