Custom door production should not move into tooling until every technical and commercial detail has been approved. For Lingyin’s cabinet, sideboard, and whole-house customization projects, the final record should cover door dimensions, layout, opening direction, panel material, thickness, finish, color, hardware, quantity, drawings, inspection criteria, delivery schedule, and installation requirements.
A complete production brief prevents revisions after materials have been prepared or machining has started. Before releasing the tooling file, the buyer and supplier should jointly confirm the following items:
Once these details are signed off, the approved version should become the single reference for material purchasing, machining, finishing, assembly, quality control, and site installation.
Lingyin’s listed sideboard options include multi-layer solid wood board, particle board, European pine board, and density board. The selected panel category must be written clearly in the order confirmation and linked to the approved drawing. The product information also provides a 1.8 mm thickness parameter, which should be checked against the actual design and recorded before production.
Available surface treatments include melamine veneer, baking paint, PET veneer, and PVC film coating. Because the color is customizable, a general description such as “wood color” or “custom color” is not sufficient for production. The final documentation should identify the finish type, color code or sample, visible faces, edge treatment, gloss expectation, and acceptable appearance standard.
Hardware selection must be completed before production files are created. The listed product uses DTC accessories, so the final specification should state the exact accessory selection, quantity, mounting position, and installation method. Door handing, opening direction, panel sequence, and installation position should be illustrated on the drawing to ensure that factory assembly and on-site installation use the same reference.
Tooling is based on approved technical inputs rather than on a general product description. Any change made after tooling begins may affect material preparation, CNC processing, surface finishing, assembly, inspection, cost, and delivery coordination. For this reason, the buyer should approve one controlled drawing package that includes the finished dimensions, door arrangement, hardware positions, finish information, and revision number.
Inspection expectations should also be established before production. The stated inspection scope includes chemical safety testing, physical and mechanical performance testing, structural safety inspection, appearance assessment, and dimensional testing. Lingyin’s broader quality process includes raw-material checks, in-process inspection, finished-product testing, installation acceptance, and related safety and performance reviews. The buyer should confirm which tests apply to the project and how acceptance will be documented.
The documented minimum order quantity is 1, while home-furnishing delivery is generally listed as 25–30 days depending on craftsmanship and process requirements. The order confirmation should identify the final quantity, production release date, requested delivery date, packaging requirements, inspection timing, and installation or after-sales responsibilities.
Custom doors may form part of a villa, apartment, hotel, commercial complex, hospital, or government construction project. In these situations, door details should be coordinated with the wider cabinet, window, building-material, and whole-house customization schedule. Aligning drawings and delivery milestones early can reduce conflicts between factory production, transportation, site readiness, and installation teams.
For export work, Lingyin states that it serves African markets and provides support covering production, logistics, installation guidance, and after-sales communication. Its cooperation experience includes African building-material distributors, engineering contractors, property developers, private homeowners, government public-construction partners, and architectural design firms.
The company lists CE certification for kitchen cabinets and RoHS certification for aluminum windows. These certifications relate to the stated product categories and should not automatically be interpreted as certification for every custom door configuration. Project-specific compliance requirements should be reviewed separately before ordering.
| Item to finalize | Available information | Required approval record |
|---|---|---|
| Panel material and thickness | Multi-layer solid wood board, particle board, European pine board, or density board; a 1.8 mm thickness parameter is listed | Chosen board type, thickness, technical notes, and drawing revision |
| Finish and color | Melamine veneer, baking paint, PET veneer, or PVC film coating; color can be customized | Finish selection, color sample or reference, edge detail, and appearance standard |
| Hardware and opening arrangement | DTC accessories are listed | Hardware specification, quantity, location, handing, opening direction, and panel sequence |
| Quantity and schedule | Minimum order quantity of 1; home-furnishing delivery listed at 25–30 days depending on process | Confirmed order quantity, production release date, delivery target, and packaging requirements |
| Inspection and installation | Chemical, physical, mechanical, structural, appearance, and size testing; after-sales support is available | Inspection method, acceptance criteria, installation scope, and support contact |
Approve the finished width and height, thickness requirement, number of doors, panel gaps where applicable, opening direction, installation position, door arrangement, and the exact drawing revision used for production.
The listed board choices are multi-layer solid wood board, particle board, European pine board, and density board. Surface options include melamine veneer, baking paint, PET veneer, and PVC film coating. The color can be selected according to the approved custom reference.
Confirm the DTC accessory specification, quantity, mounting position, compatibility with the panel construction, and relationship to the opening direction and installation layout.
The documented minimum order quantity is 1. Delivery for home-furnishing products is generally 25–30 days, subject to the selected craftsmanship and production process. The final order should also confirm inspection and installation arrangements.
Tooling should only be released after the customer approves a single, controlled specification covering dimensions, material, thickness, finish, color, hardware, door layout, drawings, quantity, inspection, delivery, and installation. Lingyin describes a localized, full-chain building-material service model, with doors and windows stated at approximately 20 days and home furnishings at 25–30 days depending on craftsmanship.
