Metal spinning advantage >>

precision aerospace and aircraft metal spun products

● Large diameter :Biggest diameter sheet metal spinning shell is over 1.3mm ,length is about 0.8mm .

● Big tube spinning:The length of tube we make tube spinning is over 0.6mm. tube thickness is over 7mm .

● Good accuracy :We testing the accuracy of diameter and thickness of  liner is 0.02mm  .

● Good surface :We supply polishing ,5 axis laser cutting ,powder coating and oxidation .

Metal spinning >>

Metal spinning is a metal forming process that can make a circular metal sheet deform different shape of revolving body .the spinning mold and clamp provide the clamping force and take the sheet to spin .When the spinning roller touch and press the sheet according to the spinning path, the sheet will produce plastic deformation from the point to the line follow the spinning path .

metal spinning work principle instruction

 

Materials>>

From 2013,we have spun over 100 kinds of metal so far ,such as copper ,aluminum ,steel ,stainless steel ,titanium and so on .We learn and test the different types of metal material .good ductility and less hardness and tensile strength is easier to spin , So we can choose the right metal to satisfy the metal forming and mechanical requirement .

 

Conmon blank metal

● Aluminum : 1060 / 1100/3003 / 5052 / 5251 /5083/ 6061

● Steel : SPCC / DC04 / Q235/ Q345  

● Silver : IC-Ag99.99   Copper : C10 100 / T1  

● Stainless steel : 201 / 304 / 316 / 310 

 

Special blank metal 

● Hardox 400   GH3044   SUS310   SUS630    

● Aluminum 2024/2A12/7075 /5A06  

● Inconel 718   TC4


Sheet spinning

basic sheet metal spinning work principle and fabrication ways

The  blank of sheet metal spinning  is a round sheet , the roller is controlled by CNC program to press and pull the blank sheet to deform different shape . Cone ,cylinder ,sphere ,trumpet, venturi are basic shape can be made by sheet metal spinning . 

Conventional  spinning :  tensile deformation is pulled by roller .

Shear spinning :  shear deformation is pressed by roller and mold .

 

Tube spinning >>

basic tube metal spinning work principle and fabrication ways

The blank of tube metal spinning is a round tube , neacking ,expand ,rolling flanging and shearing are basic forming technology in tube metal spinning ,shearing and necking are used in the military component such as missile and torpedo shell .It can improve the strength and optimize the structure .

Heating spinning

Heating spinning

Dinnovation research and develop the heating metal spinning technology>> from 2017.

Cold metal spinning is suitable to spin forming the thin and soft metal .
Heating metal spinning can process more special and harder metal and thick sheet and tube. When the thickness is too thick (aluminum 10mm, stainless steel 5mm, steel is 5mm), or the hardness is harder than stainless steel 304, such as SUS630, TC4, Incone ,Aluminum 7075, we choose the heating metal spinning to form the components.
Heating metal spinning applied in Dinnovation :  

● Oxygen bottle

● Combustor

● Aerospace component 

Spun products property

There are several important properties of spun part that is benifit your design and assessment .

● Shape : Metal spinning fabrication ways can satisfied your different design .

● Thickness :  The actual thickness is less than blank thickness after spinning .

● Property :  The strength and hardness will be improved as grain refining .

● Appearance :  Roughness can achieve 0.05-0.15mm .

● Internal stress : It is stronger than other metal forming fabrication .

● Mold cost : 30% of deep drawing mold cost , mold period is shorter .
