Ningbo Huayuan Casting Machinery Factory

NINGBO HuaYuan Casting Machinery Factory is one of China professionally manufacturer and dedicated supplier of various castings including Investment casting, sand casting and Aluminum die casting one.For investment casting, we adopt the method of soluble glass, complex shell, silicasol to make precision casting parts. And for sand casting, we adopt resin sand process to make grey iron and ductile castings.  huayan for die casting, mostly we make the aluminum or alloy aluminum casting parts.       We can produce castings with kinds of  material, such as carbon steel and alloy steel, stainless steel , grey iron, ductile iron, aluminum, brass as well as bronze.Besides, it is also available for us to supply a series of finish steps for the rough casting and metal parts,  such as finish machining, welding, heat treating,caseharden, plating, anodizing ,painting etc. Moreover, thanks to our many qualified suppliers for the rubber, plastic injectiong molding,spring, punching,stamping prouducts, that enable us to provide our customers the complete set projects while assembling the correlative products if customers request.        At our factory, quality control is an active, function of manufacturing. Quality assurance starts the minute raw materials come in the door and continues through every stage of the casting process. We achieve part-to-part consistency, so the last casting is the same high quality as the first. We work to ISO 9001:2000, a standard of excellence that is recognized around the world. To supply qualified castings with reasonable price is our permanent principle.  Dear customers, if you have any interesting to our factory, pls feel free to contact with us by email or fax. We can accept the files with the form of Pdf, Jpg, CAD, IGS, STP,Pro-E as well as SOLIDWORKS via email. huayuan soon as we receive your inquiry, we will pay much attention to it, and our experienced engineers will make a quick cost estimate to your inquiry, then will quote our competitive price to you at the earliest time.       We sincerely wish we will be your reliable casting supplier at the base of mutual benefit.

High quality aluminum die casting lighting parts

aluminum die casting lighting parts

1.Description of aluminum die casting lighting parts

OEM/ODM die, molds, molding, molds, tooling made according to customers prints, drawings, specifications or samples

OEM/ODM parts range: auto parts, industrial metal parts, machine fitting and hardware parts

Available materials: aluminum/zinc alloy, iron, steel alloy, plastic, brass, steel, stainless steel and plastic

High Strength


In making a forging, the metal is worked twice under tremendous pressures. 

First during rod extrusion, drawing or rolling and then during forging. 

The double working under pressure, compacts the metal, 

and produces a very dense and refined grain or fiber structure. 

The tensile strength of the parts is thereby increased, and resistance to impact 

and abrasion is enhanced.


Leak Resistance


The dense non-porous forged metal permits the designer to specify thinner sections without the risk of leaks. 

Often, the thinner forged parts result in lighter weight 

and lower piece cost compared to other manufacturing processes.


Close Tolerances


aluminum die casting lighting parts produced in a steel die with close tolerances offers several advantages. 

Overall part dimensions are held closer than in sand casting. 

Dimensions show minimum variation from part to part allowing 

for automatic chucking and handling in subsequent operations. 

The precise designs on the die surface can produce sharp impressions on the forging surface.


Low Overall Cost


Mass production of aluminum die casting lighting parts lends itself to maximum savings. 

However, smaller quantities of copper alloy forgings can also prove economical 

when specific design parameters must be met. These requirements include leak 

integrity, close tolerances, high strength with low weight, and non-symmetrical shape.


2.Manufacturing process of aluminum die casting lighting parts

Sand casting (iron or brass)

Forging/stamping (aluminum, brass and steel)

Die casting/vacuum casting (aluminum or zinc alloy)

Investment casting (stainless steel or brass)

Injection/extruding (plastic)


Available production processes: CAD/CAM service, expert plastic injection, metal processing, finish, heat treatment, surface plating, QC testing and packing

Available finishes: fine polished, chrome, zinc plating, powder coating and painting micro-graphic and metallurgical analysis


3.Quality control of aluminum die casting lighting parts

Advanced inspection equipments for rigorous quality and control and precise specification

Comprehensive engineering and manufacturing services for die, molds, molding, mold, tooling, R&D process, product design, test and measuring including shear

Certificate: ISO9001
