Most of the world's steel is made into finished products by stamping. The body, chassis, fuel tank and radiator sheet of automobiles, steam ladle of boilers, the shell of containers, and silicon steel sheet of the iron core of motors and electric appliances are all stamping processes. There are also a large number of stamping parts in products such as instruments, household appliances, bicycles, office machinery and living utensils.
Compared with castings and forgings, stamping parts are thin, uniform, light and strong. Stamping can make workpieces with reinforcement, ribs, undulations, or flanges that are difficult to manufacture by other methods to improve their rigidity. Due to the use of precision dies, the accuracy of workpieces can reach a micron level, and with high repetition accuracy and consistent specifications, holes nests and tabs can be stamped out.
Metal Stamping Parts Common Problems Treatment
1. Bonding, scratch: due to material and convex die or concave die friction and in the surface of the parts or mold appear bad;
2. Burr: mainly occurs in the shear die and drop die, the gap between the edges is large or small will produce a burr;
3. Line offset: when the part is formed, the first part in contact with the mold is squeezed and formed a line;
4. Convex and concave: uncoiling line with foreign objects (iron chips, rubber, dust) mixed in to cause convex and concave;
5. Zigzag: due to uneven stress, poor matching of the stretching bar or poor control of the press slider, etc., causing zigzag and strain on the r-angle part of the part or the embossed part;
6. Wrinkles: due to poor adjustment of the press slider, low precision of the press, improper adjustment of the air cushion pressure, large punch or r parts caused by the edge or r parts wrinkles.
7. Other specific problems: In daily production, we may encounter situations where the punch size is large or small (possibly exceeding the specification) and the size of the die differs greatly from that of the convex die, taking into account the design size of the forming convex and concave dies, processing accuracy and punching clearance, etc.
Metal Stamping Parts Application
1. Stamping for the automotive industry. With deep drawing as the main. In our country, this part is mainly concentrated in automobile factories, tractor factories, aircraft manufacturing plants and other large factories, independent large stamping and deep drawing plants are not yet seen.
2. Automobile and other industries' parts class stamping. Mainly punching and shearing. Many enterprises in this sector are classified as scale parts factory, there is also some independent stamping plant, and at present, some automobile factories or tractor factories near a number of such small factories.
3. Electrical parts stamping factory. This kind of factory is a new industry, following the development of electrical appliances and the development of this sector is mainly concentrated in the south, such as the Shenzhen hardware factory.
4. Dy necessities stamping factory. Do some handicrafts, tableware, etc., these plants have also had a great development in recent years.
5. Household electrical appliances parts stamping factory. These plants emerged only after the development of household appliances in China, and most of them are located in household appliance enterprises.
The Sun bids goodnight for this last trip,
As you openly gave, from an open cup, from your family harbour, to your friends harbour. Those hours of making things and discerning constellations in dark theatricality.
Thank you.
You made life beautifully fascinating, happiness and hurt and warmth, you depart this strange time as I thought you never would, a plumed bird, exotically modest, practically perplexed by others cruelty to others, In a time to mend the ills of all and a time to Listen.
listen for, shattering shards of uncoiling icebergs, listen in praise of your beauty, your humanity,
Listening deeds of those murmurations
Each and everyone relies upon The Sun to live in the shadows, to die in the setting warmth of a cloudless sky.

The purple uncoiling flowering stems of North Park phacelia (Phacelia formosula). This member of the waterleaf family (Hydrophyllaceae) is found in “North Park” of north central Colorado, near the small town of Walden. The bright purple flowers and lobed leaf margins make this species easy to spot in July and August. The plant is a biennial, surviving for one year as a rosette of leaves before flowering and dying the following year. The plant is found on barren exposures of the Coalmont Formation that are easily eroded (see the habitat pictures).

Sandwich panel lines are widely applied in the protection and decoration of outside wall for tall building and first-class office building. Sandwich panel production machinery can protect, keep warm and flame retarding. The sandwich panel production line in Jinggong can mainly produce roof panels and wall panels.
Here is the manufacturing process of sandwich panel production line:
Decoiler transverse location---Lifting stage move outside---coil hoisting—lifting stage move inside (To outside position)---Lifting stage rise (Coil center arrive at the decoiler axle center)----Lifting stage car move (To inside position)---Decoiler axle expanding (---Pressing-arm press tightly)----Lifting stage reset position---decoiler uncoiling material
Jinggong is one of the top sandwich panel machine manufacturers in China, contact us and get sandwich panel production line price!

As you can see from the above mosaic, I missed two days in May, but I'm not worrying about it. As long as I don't miss more than 2 or 3 in any month, I'm counting it as a success.
My theme for may was "Living things" (I seem to have forgotten that on the day I took the desperation shot of the pizzas!). I'm continuing in the same vein for June and my theme will be "Nature".
