Lighting Manufacturing — Custom Parts from China

A great light is part engineering, part art. We make the parts behind both — heat sinks that keep LEDs cool, housings with clean lines, and lenses and diffusers that shape the light.

Factory-direct CNC machining, 3D printing, injection molding and sheet metal fabrication. From a first appearance model to full production runs. Free DFM feedback with every quote.

How we help

Why Lighting Teams Choose YiguProto

Lighting parts must manage heat, shape light, and look beautiful on the ceiling. We understand all three — and we build them in one place.

Thermal & DFM Support

Heat shortens LED life. Our engineers review fin layout, material and finish before you commit.

Optical Clarity

Clear lenses, diffusers and polished surfaces that pass light without haze or scratches.

Speed

Fast quotes and short lead times, so your lighting line never waits.

Reliability

One accountable partner from appearance model to production — machining, molding, finishing and assembly.

Solution 01 · CNC Machining

CNC Machining for Lighting

CNC machining gives lighting parts tight fits, clean edges and a premium finish. We machine aluminum and plastic heat sinks, housings, reflectors and mold inserts — from first samples to volume orders.

Machined aluminum heat sinks with fin layouts that pull heat away from LED modules.

Housings & Reflectors

Lamp housings and 5-axis machined reflectors with the smooth surfaces optics need.

Mold Inserts & Trim

Polished mold inserts for lens making, plus bezels, trims and mounting hardware.

Solution 02 · 3D Printing

3D Printing for Lighting

Lighting is where art meets science — and you cannot judge a light from a drawing alone. 3D printing puts a real fixture in your hands in days. It is perfect for appearance models, optical prototypes and short custom runs.

Appearance & Function Models

Hand-held prototypes with real surface finish, so you can judge look and light output early.

Complex & Custom Shapes

Organic shapes, honeycomb textures and one-off fixtures sized to a specific space.

Short Runs & Bespoke Projects

Small batches and custom lighting for a building or event — without paying for mold tooling.

Best forPrototypes, appearance models, optical models and short custom runs
ProcessesSLA (clear resin), SLS, MJF, FDM, and SLM metal printing
MaterialsClear resin, nylon (PA12), ABS-like and PC-like plastics, TPU, aluminum
DetailsClear and translucent parts let you test diffusion and beam patterns before molding
Quantities1 piece to small batches — no tooling, no minimum order
TurnaroundTypically days — the fastest way to see your design lit up

Solution 03 · Injection Molding

Injection Molding for Lighting

When your lighting design is approved and demand grows, injection molding gives the lowest cost per piece. We build the mold, run pilot parts, then deliver consistent quality in volume — lenses, diffusers, housings and more.

Lenses & Diffusers

Clear PMMA and PC lenses, diffusers and light guides molded with polished optical surfaces.

Housings & Covers

ABS, PC and PP housings and covers — textured, glossy or matte — ready for assembly.

Over-Molded & Insert Parts

Soft-touch over-molding, metal inserts and 2K parts for premium fixtures.

Best forLenses, diffusers, housings and small parts in volume
ProcessesRapid tooling, production molds, over-molding, insert molding, 2K, transparent molding
MaterialsPMMA, PC, ABS, PP, PA, PBT, TPU, TPE
ToolingPolished optical tooling; aluminum bridge tooling for pilots; hardened steel for production
QuantitiesFrom pilot runs to millions of pieces
TurnaroundPrototype parts in days; production timing follows the tooling build

Solution 04 · Sheet Metal

Sheet Metal Fabrication for Lighting

Industrial and commercial fixtures live in sheet metal. We laser-cut, bend and finish aluminum and steel into housings, brackets and ceiling plates — with no tooling for prototypes and fast turnaround on single pieces or volume orders.

Housings & Troffer Bodies

Troffer bodies, high bay housings and panel frames cut and bent from aluminum or steel.

Mounting Plates & Brackets

Ceiling plates, mounting brackets and junction boxes that hold fixtures securely.

End Caps & Back Plates

End caps, back plates and covers that close the fixture and hide the wiring.

Best forHousings, brackets, ceiling plates, end caps and covers
ProcessesLaser cutting, CNC bending, punching, welding and assembly
MaterialsAluminum, steel, stainless steel, copper
Surface finishPowder coating, anodizing, electroplating, brushing
QuantitiesSingle prototypes to volume — laser-cut parts need no tooling
TurnaroundQuotes within 24 hours; prototypes typically ship in days

How we work

From Appearance Model to Production — Five Clear Steps

You always know where your project stands. Here is the path most lighting projects follow with us:

Share your files

Send 2D drawings or 3D models (STEP, STP, IGES, STL). Tell us the quantity and where the fixture will be used.

Free DFM review & quote

Our engineers review the design — including thermal and optical needs — and return a quote within 24 hours.

Appearance model & first article

We make a first sample so you can see the light in real life. You approve look, fit and light output before production.

Pilot run

We confirm the process with a small batch. Adjustments to design, material or finish happen here — while change is still cheap.

Production & delivery

We scale up with stable quality and on-time delivery. Inspection reports travel with every batch.

Quality & Trust

Quality You Can Verify

Good lighting parts are proven, not promised. Our quality system checks every stage, so your fixtures perform on the first install and the thousandth.

Incoming Material Control

Material certificates for every lot, so what arrives matches what you ordered.

First Article Inspection

A full dimensional check on the first piece before the run begins.

In-Process Checks

Operators verify critical features during the run — not only at the end.

Final Reports & NDA

Dimensional and inspection documentation with every order. Your files stay confidential.

Materials & Finishes

The Right Material for the Light

Material choice decides how a fixture handles heat, impact and light. Tell us your conditions, and we will suggest a grade that fits your budget.

Metals

Aluminum 6061 and 6063, stainless steel, brass and copper — strong, thermally efficient and easy to finish.

View metal materials →

Optical & Engineering Plastics

PMMA (acrylic), PC, ABS, PA, PBT, TPU and TPE — clear, tough and moldable.

View all materials →

Finishes That Show

Anodizing, powder coating, chrome and metal plating, polishing, brushing and bead blasting.

Heat sinks, housings and precise metal parts fit CNC machining. Prototypes and appearance models fit 3D printing. Lenses and diffusers in volume fit injection molding. Industrial fixtures, brackets and covers fit sheet metal fabrication. Send your file and our engineers recommend the best route for free.
Yes. Heat shortens LED life. Our engineers review your thermal design — fin layout, surface area, material and finish — and suggest changes that improve cooling at lower cost.
Aluminum 6061 and 6063, stainless steel, brass and copper for metal parts. PMMA (acrylic), PC, ABS, PA, PBT, TPU and TPE for optical and molded parts. We match the material to heat, impact and light-transmission needs.
Yes. We print clear resin prototypes for optical testing, and injection mold production lenses, diffusers and light guides in PMMA and PC with polished tooling for clean light transmission.
Yes. We make a first article for your approval — especially useful for lighting, where look and light output must be judged in real life. Sample cost depends on the process, and it is credited back on a production order.
Anodizing, powder coating, chrome and metal plating, polishing, brushing and bead blasting. We match the finish to the material and the look your fixture needs.
We inspect incoming material, run first article and in-process checks, and provide dimensional reports with every order. All customer files are confidential, and we sign NDAs on request.
