Jinjiang Shoe Materials Accelerate Innovation

Recently, according to market According to sources, Japan is represented by Mitsui, due to the earthquake. Imported There is a shortage of chemical raw materials in varying degrees. Shoe material The price of chemical raw materials is also like the arrow on the string, which is facing the price increase at any time. No one thought of a huge impact on Jinjiang shoe material industrial chain, a new round of material. Price increase The tide will be on again.

"EVA price rises with natural rubber. It will take a few days. purchase Rubber, EVA and other chemical materials must also be. When the river rises, the boat floats high " Recently, Mr. Ding, a shoe processing enterprise in Chai Tai, Jinjiang, is a little worried: there are not many chemical materials left in the factory stock.

However, it was far more than that. Because of the price fluctuation of chemical raw materials, some suppliers began to digest the rising cost through adulteration of additives, which directly led to the decline of the purity of chemical raw materials. In addition, in spring, it was wet and rainy. A group of shoe materials appeared physical changes one after another. Among them, the shoe sole quality inspection represented by the two MD was extremely unstable, which could not guarantee the normal delivery period, and seriously affected the production process of the upper shoe manufacturers.

As a shoe supplier, how can they cope with the quality crisis brought by this chemical raw material panic and adopt a foresight method to add a safety quality lock to the supply chain? Perhaps, the practice of sole manufacturer of new spring Shun and Guo Fa is worth learning from the industry.

　　 Chemical purity of EVA based chemicals declined.

Today, most of the raw materials of shoe material enterprises come from Japan, Korea and Taiwan, China. According to the footwear industry in Jinjiang, in the rubber, EVA and other shoe materials, EVA as the main material of the popular shoe materials, the price fluctuation will directly affect the cost of the local shoe material enterprises. Although the price is higher than that of the domestic chemical raw materials, its physical properties are stable and the quality is relatively guaranteed, which is favored by most shoe material enterprises in Jinjiang.

After the earthquake in Japan, the shortage of chemical raw materials imported from Mitsui became an inflection point. Once again, the price of EVA and other chemical raw materials was pushed onto the soaring roller coaster. Under such a dilemma, Jinjiang shoe material enterprises had to temporarily replace the chemical raw materials of domestic brands.

"There are dozens of chemical raw materials to be used for a pair of shoes. Any small amount of chemicals that are produced by any chemical raw material may affect the foaming quality, oil pressure and other production quality of the sole, let alone EVA granulation." Ding Guozhi, general manager of new spring shoe material Co., Ltd., told reporters that whether it is disposable EVA ejection soles or two times MD, the purity of EVA granulation has a direct impact on their quality.

"At present, even if we can buy imported chemical raw materials, most of the purity is not enough. Our source suppliers, because of prices and materials are tight, and so on, recently, this batch of raw material purity has dropped to varying degrees. Therefore, due to the lack of elasticity caused by the lack of elasticity, some conventional quality problems such as bubbles fail to meet the standards are coming, and the quality of their shoes is also unstable."

Ding Jinrui, deputy general manager of Guo Fa shoe industry Co., Ltd., said that although the panic buying caused by the panic of Japan's Mitsui chemical industry has subsided rationally, the chemical raw materials are closely related to the shoemaking industry chain, and the industry is still constantly analyzing and estimating. However, the purity of chemical raw materials can not be improved in a short time.

　　 Trying to replace materials

Behind this energy crisis, a group of material innovators represented by Cheng Chang and Xin Quan Shun have emerged in Jinjiang's shoe materials. Joint research institutes on shoe making have begun to study new materials instead of traditional EVA granulation, hoping to solve the problem of insufficient purity of EVA chemical materials and ensure physical stability, even in bad weather.

Ding Guo laughs, after joining a scientific research institution, during this period of time, he pulls all kinds of chemical raw materials to the teacher every day to consult with his teacher. He is determined to thoroughly study the chemical properties and physical properties of these new materials, and then tries to replace the improved formula on the basis of raw materials to avoid the quality problems caused by the purity of chemical raw materials.

Coincidentally, following the introduction of consulting and management companies to standardize the production process and create the first laboratory in the shoe and foam industry, Cheng foamed this year will start to study new materials instead of traditional EVA granulation.

Of course, the real intention of Cheng Long foaming is to get rid of the limitation of EVA granulation as the main material. Whether it is raw material price or purity quality control, we expect a relatively mature substitute for new materials, so as to achieve the goal of ultimately reducing the cost of products. Under this premise, who can first develop new materials that replace raw materials of traditional EVA raw materials, who will be able to hold more chips in the market competition? For this point, Ding Changgang, general manager of the company, saw clearly.

In fact, the Dongyuan industrial Limited by Share Ltd was founded in 1978. It is a Taiwan enterprise mainly engaged in import and export trade in all kinds of plastic raw materials and chemicals. "The cooperation between Cheng Chang and Dongyuan is not a purely supply and sale relationship. Specifically, Dongyuan will become a think-tank in the new material experiment of Cheng Long, and gather more development ideas and trends for Cheng Chang. Ding Changgang said.

　　 Increase control range or self feed pelletizing line.

Whether it is Xin Quan Shun or Cheng Long, it is hoped that the new material will try to avoid the influence of purity on quality and effectively improve the quality and stability of products.

However, a pair of shoes, even a small piece of foamed materials, requires dozens of chemical raw materials to adjust their proportions and proportions. From experiment to production, and finally to mass production, this road is not easy to go.

Therefore, some people believe that instead of putting the inputs and outputs into direct proportion, it is better to control the quality problems caused by the purity of chemical raw materials by improving the quality of the source. Ding Jinrui believes that it is not easy to replace the formula and proportion. Once it is replaced, it will take a long time to test the market. The quality of this time will fluctuate, and it will be better to control the source of production.

And reporters recently walked into the spacious production workshop of Jinyi shoe material Co., Ltd., and saw the control of Jinyi on the source of production raw materials.

Here, the production line and the ground are spotlessly clean. Ye Yanxiong, sales manager of Jinyi shoes material Co., Ltd., told reporters that the company always put quality safety in the first place. In order to make EVA production really reach the downstream supplier's quality standard, Jinyi production adopts strict quality control measures before, during and after production. From the first process feeding, suppliers must provide EVA granulation inspection report of local related departments. Before selecting materials, EVA granulation must be cleaned up again and screened out of impure impurities, and debris should be eliminated, so as to ensure the purity of each chemical raw material is up to standard.

It is understood that in the more than 20 processes of EVA control and production, China has established the corresponding inspection quality supervision system, which mainly controls the import of raw materials, production links and inspection of product quality, from raw materials to products into the market, and the quality of products has been tracked in the whole process.

In fact, as long as we can tighten the string of quality safety and insist on building quality and rest shoes, this raw material storm will soon disappear.
