Factory and capabilities
Manufacturing capability for hardware buyers who need more than a catalogue image.
The supplied company catalogue presents a Dongguan workflow covering design, metal production, surface treatment, assembly, inspection and packing. The exact process and acceptance criteria remain specific to the part.
Manufacturing flow
Keep design intent connected to production.
A buyer can use this sequence to ask where a decision is made, which sample proves it and what record should be approved before the next stage.
Product design & CNC
Review the drawing, structure, interfaces and visible details. CNC work can support detail review where appropriate.
Tooling & die casting
Move an approved geometry toward mould development and zinc-alloy die-cast production for suitable components.
Stamping & lathe work
Discuss stamping or automatic-lathe routes when the material, shape and production requirement fit those processes.
Polishing & plating
Align the surface preparation, plating colour and finish reference. The supplied information describes in-house plating capability and external processing discussion where needed.
Assembly & QC
Connect moving pieces, inspect agreed dimensions and record the project-specific checks before packing.
Packaging
Discuss packing protection, including protective film at shipment where the finish needs help against scratching.
Material and finish discussion
Zinc alloy is the starting point. The application decides the route.
The basic company information identifies zinc alloy as the main material. Copper, iron and stainless steel may also be discussed for suitable designs. Common colours can be developed as project requirements, with the final finish confirmed against a physical reference.
- Primary materialZinc alloy for many custom three-dimensional hardware parts.
- Other optionsCopper, iron and stainless steel can be discussed where the component calls for them.
- FinishPlating colours and custom colour directions should be approved on the actual part.
- ToolingTooling is commonly discussed around USD 300-800, subject to geometry and project scope.
Finish colour should be approved against the physical reference and the actual production part.
Quality support
Ask for the evidence that matches the product risk.
The supplied knowledge file describes a practical set of checks rather than one universal specification. Define the load, movement, duration and acceptance target before a test starts.
- FunctionLock opening and closing, hook movement and engagement.
- LoadPull-force discussion for relevant parts, including dog clips.
- Movement1 kg or 2 kg packed-product vibration scenarios can be discussed.
- SurfaceSalt spray commonly discussed at 24 hours, or 48 hours for stricter requirements.
- DocumentationAn electronic SGS report may be available for the relevant project scope.
Test method, sample condition and acceptance target must be agreed for the specific part.
