(Summary description)"Hong Chong" is actually a hot extrusion process, because the manufacturing in coastal area of Zhejiang industry, especially the pipeline hardware manufacturing industry, if someone says "extrusion", not much can immediately notice the meaning of people, when it comes to "red" two words, so people will know it is what kind of process? The mold of what? Which product? In addition, the name "process red" this name and reality closely relationship and other sound reasons, so it is easy to accept.

Information

"Hong Chong" is actually a hot extrusion process, because the manufacturing in coastal area of Zhejiang industry, especially the pipeline hardware manufacturing industry, if someone says "extrusion", not much can immediately notice the meaning of people, when it comes to "red" two words, so people will know it is what kind of process? The mold of what? Which product? In addition, the name "process red" this name and reality closely relationship and other sound reasons, so it is easy to accept.

Hong Chong punching process: "Hong Chong" is a new word in the dictionary, more difficult to find its place. Because red blanking technology is an advanced technology from modern precision forging and hot extrusion is developed on the basis of. With the social progress, the development of science and technology, mechanical industry put forward new requirements of mechanical strength of mechanical parts. Improve the mechanical strength, generally use two methods, one is to change the parts of the material, the two is to change the processing method. Hong Chong punching process is by changing the processing method to one of the effective ways to improve the mechanical properties of parts, so instead of forging process, has a strong vitality and good prospects for development. Hong Chong punching process like forging processing that will heat the blank after metal on the mold forming, but Hong Chong in addition to a large Hong Chong pieces are generally is a one-time forming, and precision forging is generally a few times pressure forming. Hong Chong hot extrusion process and compared, metal blank also need heating, hot extrusion die with cold extrusion mould basically the same, metal material is simple in the cavity flow, the shape of parts forming, most of the cold extrusion parts almost, bias is relatively simple shape part forming complex structure, specific heat and red stamping die extrusion die, structure is characterized in that the organic combination of stamping and forming mold, it not only can squeeze in the press molding cavity extrusion die, mold release action but one can implement multi azimuth, it strong enough pressure, forcing metal materials by the complex flow in the mold cavity, extrusion imaging cavity die (mould) complex shape parts. So the development of red is the process of precision forging and hot extrusion process of deeper and wider breadth.

Hong Chong punching technology advantages

1) Forming basically not affected by its external shape parts Limited.

2) Production using common equipment, operation easy, suitable for small and medium-sized enterprise production.

3) The productivity is high, suitable for mass production.

4) Because of the use of core pulling device, the internal parts pressed out of the hollow forging die, not processed parts as internal is solid, and the edges of small Hong Chong die thickness at about 0.5mm, and burr thickness forging mold is generally more than 2mm, so the material utilization rate is much higher than the forging die.

5) Hong Chong is a processing technology of less or no cutting, surface roughness is close to die, precision can reach 6-7 level, so it is very small mechanical cutting.

6) The mechanical properties of the Hong Chong, because Hong Chong metal blank after heating, extrusion, cooling, the metal structure change, the defect was eliminated because the original casting or drawing caused, the parts of internal crystal structure is from the inside to the outside line, improve the mechanical properties of the Hong Chong parts.

7) The Hong Chong after the parts, metal inside the grain has been refined, enhanced the density of metal parts, improve the ability of corrosion resistance.

8) It's suitable for various kinds of colored or black metal processing.

Because the Hong Chong blanking technology investment little, high production efficiency, product quality, and is suitable for mass production, resulting in a good economic effect. For example, red punching process in daily hardware industry, has been widely used, such as all kinds of valves, plumbing hardware with Hong Chong copper pipe in the connecting piece, nut etc., to the quality of its incomparable advantage, has replaced the past has been using the die casting or casting products. Hong Chong, general manufacturing industry in Zhejiang, especially the pipeline hardware manufacturing industry in broad terms.

Red character method

Rubric strike method abbreviation, red character method also known as the scarlet letter corrections, refers to the use of the scarlet letter reversal or offset the original error record, to correct or adjust the method of accounting errors. Red character method according to the different the write off the wrong account procedures, can be divided into a full character method and the difference of two kinds of charge off method. Full character method refers to the wrong account all the scarlet letter write off, then the preparation of accounting documents the right to correct the wrong account. Account after the discovery should borrow, loan accounts should be wrong voucher when using, should correct the full character method. The difference character method refers to the note amount shall be deducted. The correct method of accounting vouchers in later discovered, shall be no account should borrow loans mistake, just remember amount greater than the amount should be recorded, should adopt the difference character method.
