DFM Structural Pre-Check

Optimization advice within 24 hours of receiving your drawings.

Most approval risk is hidden in the drawing. Before we quote or cut a single panel, our engineers run a DFM (Design for Manufacturability) structural pre-check, so waterproofing, installation, and cost problems surface while changes are still cheap.

Waterproof dead corners

We flag where water pools, where seals are hard to compress, or where glass-to-wall gaps invite leaks — and fix the structure before production, not after installation.

Installation feasibility

We verify opening method, tolerances, and hardware positions against real site conditions so installers do not discover avoidable problems after arrival.

Value Engineering

For project orders, we propose profile, hardware, and glass optimizations that preserve function and appearance while reducing cost and waste.

Response SLA Every international inquiry answered within 12 hours · DFM feedback returned within 24 hours · technical support within 24 hours.

Design Support Capability

A 12-person R&D team behind every drawing.

Design support is more than sending a CAD file. Our 12-person R&D team covers modeling, detailing, installation structure, and market trend analysis — so the product is both buildable in the factory and sellable in your market.

Capability 01

CAD & 3D modeling

We turn your concept or drawings into accurate CAD drawings and 3D models the factory can build from directly — no reinterpretation on the shop floor.

Capability 02

Node & detail drawings

We detail glass-to-wall connections, hinges, seals, and hardware so nothing is left to site improvisation.

Capability 03

Installation structure design

We design the mounting structure, opening method, and hardware positions around real site conditions so installation stays predictable.

Capability 04

Market trend analysis

We track market trends and best-selling directions to help OEM / ODM clients refresh styles and plan new SKUs.

Prototyping Flow

From confirmed drawing to mass production in six controlled steps.

Each step locks a decision, so mass production always starts from an approved package — never from memory. This is how a sketch becomes a traceable, buildable specification.

1 24h

Drawing Confirmation

Dimensions, configuration, finish, and special notes confirmed. DFM structural feedback returned within 24 hours.

2 R&D

CAD Deepening

The 12-person team deepens CAD / 3D models, node drawings, and the installation structure into a buildable spec.

3 15 days

Sample Production

Custom samples produced in 15 days, so you verify fit, surface, and function before committing to volume.

4 Checked

Sample Inspection

Samples checked against the approved spec — dimensions, surface finish, and hardware function — before leaving the factory.

5 Locked

Customer Confirmation

You approve the sample. We lock the drawing version, finish, hardware, and packaging expectations for the batch.

6 30 days

Mass Production

Production follows the approved package: first order 30 days, reorders 20–25 days, MOQ from 10 sets.

Version control: mass production follows the approved drawing / sample package only Tooling: custom molds retained for your reorders Protection: NDA for exclusive designs
OEM / ODM Customization

Your brand, from product to packaging — protected by NDA.

For brand owners and importers, full OEM / ODM customization backed by our own aluminum, glass, and assembly workshops — so your design stays consistent from the first sample to every repeat batch.

Custom 01

Logo & branding

Your logo and brand identity applied to the product and the packaging.

Custom 02

Surface treatment

Finish matching to your sample or color code, including corrosion-resistant PVD coating options.

Custom 03

Glass customization

Glass options built on Xinyi glass base material, with thickness, pattern, and coating choices.

Custom 04

Packaging & manuals

Honeycomb cartons plus reinforced wooden crates with room- or unit-based labeling, and a professional illustrated installation manual in every order.

NDA & mold retention We sign NDA confidentiality agreements — a practice built on exclusive hotel designs — and keep custom molds for your reorders only, so your design stays protected and consistent.
Customization Case · Canada

26 apartment bathrooms, one unified spec, less rework.

In September 2025, Ms. Olivia Bennett, procurement lead for the MAGUIRE apartment project in Canada, needed a complete bathroom package for 26 units — faucets, showerheads, shower doors, solid-surface wall panels, and solid-surface bases. Her concern was not unit price but whether everything would match in style, fit in size, and install smoothly on site.

MAGUIRE Apartment bathroom project in Canada with matched shower enclosure, solid-surface wall panels and shower base supplied as one coordinated package

Dimension deepening

Our engineers confirmed the shower door opening method, solid-surface base dimensions, wall panel cutting, and hardware positions for each layout before quoting — not after.

Unified color scheme

We recommended same-color-family hardware paired with easy-clean solid-surface wall panels for a unified, modern look that is easier to maintain.

Per-unit packaging

Each bathroom was packed independently and labeled with room number, product, and installation position, so the local team sorted fast and reduced rework.

“Health solved more than our procurement problem — they made the whole bathroom system easier to install and easier to maintain, and gave the apartment project a more unified, high-end finish.”

FAQs

Frequently asked questions about design & prototyping

Six questions buyers ask most often about design and prototyping – covering DFM review, drawing changes, sample lead time, NDA and molds, MOQ, and what must be confirmed before mass production. Tap a question to read our standard answer.

Why should this page exist separately from general service content?

For project buyersBecause drawings, samples, approval loops, and version control determine whether the order enters production cleanly or starts with hidden risk.

Can you review our own drawings and suggest changes?

For engineering and procurement teamsYes. We can review customer drawings together and discuss manufacturability, fit, hardware direction, packaging, and installation-facing details before production begins.

What must be confirmed before mass production starts?

For brand owners and wholesalersThe key items are dimensions, finish, hardware, packaging direction, labeling, and the approved version of the drawing or sample package that production should follow.

How long does a custom sample take?

For project buyers and designersA custom sample takes 15 days from the confirmed drawing. The sample lets you verify fit, surface, and configuration before the order is committed to mass production.

Will you sign an NDA and keep our custom molds for repeat orders?

For brand owners and OEM / ODM clientsYes. We sign NDA confidentiality agreements – a practice built on exclusive hotel designs – and we keep custom molds for repeat orders, so repeat batches stay consistent and your design stays protected.

What is the MOQ for custom or OEM shower door orders?

For importers and wholesalersMOQ starts at 10 sets for our main models, such as JL712, JL139, and JK1934. Custom OEM details – finish, glass, packaging, and logo – are confirmed at the drawing stage.
