Submit your drawing for free DFM analysis & quotation
Dongguan Henghui Hardware is a one‑stop custom precision hardware machining factory located in Dongguan China. We focus on custom CNC machining service for global industrial buyers. We deliver custom‑made metal and plastic components from rapid prototype machining, small‑batch trial run to high‑volume mass production. We offer free DFM (Design for Manufacturability) analysis for every drawing submission, together with full‑range material choices, complete surface finishing and custom logo marking. Our custom machined parts widely serve lighting fixture, medical beauty instrument, furniture hardware, automotive and other industrial equipment projects. Our goal is to help overseas clients cut development risk, simplify multi‑supplier procurement and get cost‑effective precision custom parts with stable quality.
Our Complete Precision Machining Processes
We support a wide range of custom machining processes to cover different custom‑part manufacturing requirements. Our core services include CNC machining service (Dongguan-based), custom CNC milling service, precision CNC turning service, 5-axis precision machining service for aerospace/medical devices, custom metal stamping service and sheet‑metal laser cutting service and custom prototype machining service for automotive/consumer electronics, and non-standard CNC parts customization
Our CNC milling handles complex curved profiles, irregular‑shape hardware parts and multi‑cavity structural components.
Our CNC turning produces smooth‑surface shaft, sleeve, bush, bolt, thread precision shaft, gear, and rotary custom metal parts with tight dimensional tolerance.
Our laser cutting delivers clean burr‑free cut for metal sheet and profile workpieces without extra secondary grinding.
Our prototype machining service supports new‑product R&D, functional prototype test and pre‑production verification.
It helps you shorten your product development cycle before you launch formal mass‑batch orders. Whether you need single prototype piece, low‑volume short‑run parts or large‑scale custom hardware production, our machining workflow can match your project demand.
Broad Material Selection: Common Materials, Special Alloys and Imported Grade Materials
Different end‑use environments call for different raw‑material performance. At Henghui Hardware, we process common industrial materials, special high‑performance alloys and premium imported materials for custom CNC‑machined parts.
Our regular processed metals cover aluminum alloy, brass, pure copper and stainless‑steel for most general‑purpose custom hardware work.
We also machine many kinds of engineering plastics such as ABS, PC, PPS, PEEK, PET, POM and nylon for lightweight, insulating and low‑wear custom plastic components.
For high‑end or harsh‑working‑condition projects, we accept special‑alloy parts processing and imported‑grade material custom machining. All common materials, special materials and imported materials can be selected following your drawing specification, mechanical‑performance requirement and target‑product budget.
Full‑Set Surface Finishing and Custom Logo Branding Service
Surface finishing improves custom‑part anti‑corrosion performance, surface hardness, wear‑resistance and visual appearance.
We provide one‑stop metal finishing work so you do not need to coordinate separate third‑party finishing vendors.
Our aluminum‑part treatments contain standard anodizing and hard anodizing.
We also offer sandblasting, wire‑drawing, blackening, electrophoresis, zinc plating, nickel plating and chrome plating.
For protective coating needs, we support powder coating, spray painting and baking paint to realize multi‑color surface protection effect.
For OEM brand requirement, we deliver many logo‑customizing solutions: screen‑print logo, laser‑marking logo, CNC engraving logo and chemical‑etching logo.
All surface‑finish options can meet RoHS compliance requirement for European‑American export custom parts.
Custom‑Machined Parts for Multiple Industry Application
Our custom precision hardware and plastic components fit many real‑world industry applications.
We produce custom lighting fixture accessories with good heat‑dissipation performance and fine surface look for indoor‑outdoor lighting equipment.
We make high‑precision medical beauty instrument parts that follow safety and cleanliness requirements for beauty‑medical device assembly.

Equipment, Skilled Team and Strict Quality‑Control Workflow
Reliable custom‑part quality comes from advanced production hardware, experienced operators and systematic inspection rules.
Henghui Hardware runs modern CNC machining centers, precision CNC lathes, automatic laser‑cutting machines and matched surface‑treatment equipment.
We are equipped with measuring instruments to check dimension tolerance and surface quality for finished custom parts.
Certified by ISO9001:2015 quality management system
We follow full‑process quality‑control steps: incoming raw‑material check, in‑process sampling inspection and finished‑product full inspection before shipment.
Equipped with coordinate measuring machines + AI visual inspection technology for dimensional accuracy testing
Achieves 0.001mm-level processing precision for CNC turning, milling, 5-axis machining, and high-precision metal stamping
Every product-whether CNC-machined components, 5-axis processed parts, custom stamped parts, or custom molds-undergoes rigorous testing to ensure stability and reliability.
Our engineering team consists of technicians with many‑year precision‑machining background. They read customer CAD drawings, carry out free DFM review, point out potential manufacturability risks and give practical process‑optimization advice to lower your project cost.
Every batch custom‑parts will pass dimension and appearance testing before packing and delivery.
Sampling lead‑time normally takes 3‑5 working days; small‑batch production lead‑time runs 7‑10 working days.
We can arrange urgent‑order support for time‑critical custom‑machining projects.
