Half Century Love Between Jin Fushou And Sealed Zippers

It may be hard for us ordinary people to imagine that when people dive into the sea for tens of meters or even hundreds of meters, the most feared situation is not the attack by carnivorous fishes, but the fear of the breakage of the diving suits.

Because once the diving suit is breathable and permeable, the human body will not be able to endure bleeding due to the enormous pressure of the sea water, and then the body will even explode, so the sealing performance of the diving suit is closely related to our personal safety.

And the important auxiliary material for making diving suit zipper's sealing ability is also an important consideration index for the performance of diving suit.

If the zipper is not sealed, the seawater will also slowly infiltrate into the diving suit from the zipper's teeth hole, resulting in serious consequences.

In the zipper field, Japan is famous for its YKK, BDM and OEB in the world.

Especially in the field of special industry, the water gas seal zipper is more famous for BDM.

Because as early as 1952, BDM acquired British patent technology.

Subsequently, YKK and OEB bought the patent technology of BDM, and began to produce the highest technical water vapor seal.

A retired old man in China spent 8 years on his own perseverance and research. Finally, in 1998, at the age of 68, he developed a TM brand zipper which had patent technology in China, and passed the Blackpool and The Fylde College (Bly Poole and field college) in the United Kingdom.

The old man is Jin Fushou, an old technician who began to learn to do zippers at the age of 13.

Then why did he not enjoy his old age after retirement, but he wanted to study the water gas seal zipper?

abroad

Stimulate his research enthusiasm

It goes back to the early 60s of last century when our army shot down a US U2 reconnaissance aircraft that was reconnaissance in our country.

After the plane crashed into the sea, our crew salvaged a sealed computer from the plane. After starting up, the computer still works normally. This is amazing.

As we all know, computers and other electronic products are most afraid of water, and the computers that fall into the sea can still work. One shows the quality of the computer itself, and the two shows that the packaging performance of the computer is excellent.

Sealed and impervious packaging materials are easy to find, but to ensure that the zipper joints of bags can also be impervious and breathable, there is a high technical level.

The water gas seal zipper is the key to ensure that the computer is not penetrated by water.

Subsequently, the computer was sent to Tsinghua University for research.

Testing {page_break} through British Standard

Owns the first patent in China

For various reasons, until Jin Fushou retired, the water gas seal zipper was not successfully developed in Beijing zipper general plant, but this not only failed to shatter the dream of Jin Fu Shou, but rather stimulated his determination to study.

His idea was subsidized by a businessman from Hongkong. In 1990, he used 200 thousand Hong Kong dollars to open a zipper factory in front of his home in Jiaxing.

In the absence of professional production equipment, no mold, no testing tools, no raw materials, everything started from scratch.

8 years passed, and in August 1998, all the supporting equipment developed by Jin Fu Shou, the first TM brand water vapor seal zipper was finally born.

However, after being sold to a diving suit factory in Britain, the zipper was shot dead after testing, because some of the testing data were not up to standard.

Jin Fushou did not give up.

After getting the standard data of his products, he faced the "focus" and "drug" in one place and one place. Finally, he passed the test and certification of Fleetwood Testing Laboratory ISO9002 FS12369 in Blackpool and The Fylde College in November of that year.

Subsequently, Kim Fu Shou applied for 4 utility model patents and 1 designs patents.

40 meter long zipper sells for 10 thousand yuan.

Need to make 24 hours.

Conventional water and air seal zippers are mostly used in diving suits. In the sea water less than 20 meters away from the sea level, there is no need to add oxygen to the diving suit. If we go deep into the sea area of thirty or forty meters or deeper, we need to add oxygen to the diving suit so as to ensure the safety of the divers.

If the zipper technology does not pass through, causing air leakage and pressure differential, the diver will bleed or explode, so a seemingly invisible zipper is the lifeblood of human life.

In addition to being used in diving suits, it has a more important role in making a sealed zipper on the bags of rockets and missiles.

Compared with the missile, the rocket is a giant, usually with a zipper about 40 meters long.

This requires more precise, precise and precise technology.

The 40 meter long zipper needs 24 hours to complete, and the selling price is as high as 10 thousand yuan.

In addition, sealed zippers can also be used in other protective clothing such as lifejackets, firefighting clothes, fishing suits, pressure relief clothing, anti pollution clothing, radiation protection clothing, etc. cover and cover products, such as aero engines, power generation devices, defense equipment, mechanical tools, containers, etc., for water sports products, such as water walking balls, surfing clothes, liferrafts, hovercrafts, hatch covers, etc., the use of zippers can be said to be very extensive.

The equipment is semi-automatic and semi manual.

Upgrade to full automatic production

At present, with the increasing market space of water gas seal zippers and huge profits, internationally, apart from the few brands such as YKK and BDM, there are 5 enterprises in China, including TM.

But the production equipment is still in the semi automatic semi manual stage, resulting in low productivity and unstable quality.

In order to change this situation, this year's 80 year old Jin Fushou did not meet the sales volume of nearly ten million yuan a year. Instead, he went to Beijing to devote himself to studying and using the software development technology of Zhongguancun to continue to research and develop automatic production equipment.

Not long ago, when a reporter walked into the research room of Jin Fushou's old man, accompanied by rhythmic rhythms of the machine, Jin Fushou showed his new generation of automatic production equipment of water and gas seal zipper to reporters.

It is understood that after this equipment has been put into operation, one worker can see 10 machines, one machine can produce 60 meters zipper 8 hours a day, which not only greatly improves the production efficiency, but also improves the quality of products.

At present, TM brand water vapor seal zipper has been sold to Taiwan, China, and Italy, the United Kingdom and other European countries.

With the expansion of TM brand in the international reputation, Italy diving wave surfacing equipment accessories Association will cooperate with it to further expand the influence of TM brand in the international market.
