During May 1, I went to my uncle's production internship. He is an individual businessman, a businessman specializing in the production of sisal wheels. With advanced production equipment and production processes, fully integrated with the market to meet the needs of the polishing market. Now can produce a variety of specifications of large, medium and small sisal wheel specifications The product is widely used in a variety of metal surface polishing treatment, best-selling throughout the country. In line with the "better, stronger, higher" concept of development, while advocating the "sincerity, faith, fine, beautiful" beliefs, all from the actual interests of customers, do everything possible to reduce costs and maximize the benefits to customers.
Listen to the introduction, this sisal wheel belongs to the category of abrasives. Its advantages are: anti-corrosion, friction resistance, elasticity, strong throwing power, no static electricity and good fire performance; mainly used for stainless steel, stainless steel tableware, hardware and other products of the surface, corner polishing, grinding.
The main processing raw material of sisal wheel is sisal cloth, sisal cloth is woven from sisal. So, what exactly is sisal plant? Sisal is a leaf fiber crop of the Agave family Agave, native to the Lungatan Peninsula in Mexico, scientific name: Agave Sisalana Perrine. English name: Sisal. Alias: Sisal hemp. Sisal leaves are sword-shaped, hard and narrow, the blade is generally 100-140cm long, 13-15cm wide, gray-green to blue-green. Sisal has a warm, drought-resistant characteristics, suitable for the tropics, with a wide range of regional cultivation. The main producing countries are Mexico, Brazil, Tanzania and other countries, in China, mainly grown in Zhanjiang Leizhou Peninsula and some areas of Guangxi. Zhanjiang sisal cloth is relatively soft, small sisal filaments, made of sisal wheel is more durable, but slow polishing up light, mostly used for imported stainless steel polishing. As for Guangxi sisal cloth made of sisal wheel is harder and more brittle, grinding easy to see the light, but not durable, because it is easy to break, mostly used for domestic stainless steel polishing.
In addition, the sisal blade is rich in fibers, fiber cells were long structure, the cell cavity is large and long, thick wall, with long fibers, white color, tough texture, elasticity, strong tensile strength, abrasion resistance, acid and alkali resistance, corrosion resistance, and not easy to slip characteristics, widely used in fisheries, navigation, mining, transportation, oil and other businesses, long sisal can be made into handicrafts, the short only weaved into the sisal cloth. Sisal cloth. Sisal cloth, Chinese standard name: Sisal cloth English standard name: Sisal cloth, woven by sisal yarn, strong texture, is friction, corrosion resistance, can be used for machinery and other products of various packaging, but also the production of polishing wheels is an excellent material. If not see with my own eyes and hear with my own ears, I would not have thought that this kind of leaf blade like a sword like plant, a kind of Agave family Agave genus of leaf fiber crops can have so many kinds of uses. In the internship I found that in recent years, the price of sisal is rising, from 3400 yuan per ton last year to 4400 yuan per ton, a full increase of 1000 yuan, so the price of sisal cloth has risen to 10,000 yuan per ton. What's going on here? It turns out that the international market demand per year in accordance with the International Food and Agriculture Organization statistics of 1 million tons, the world is now less than 300,000 tons of sisal fiber, all agricultural products are almost all products to find the market but the sword.
If not seen with their own eyes and ears, I certainly do not think that this blade like a sword like plants, an Agave Agave leaf fiber crops can have so many uses. In the internship I found that in recent years, the price of sisal is rising, from 3400 yuan per ton last year to 4400 yuan per ton, a full increase of 1000 yuan, so the price of sisal cloth has risen to 10,000 yuan per ton. What's going on here? The original international market demand per year in accordance with the International Food and Agriculture Organization of the 1 million tons of statistics, the world is now less than 300,000 tons of sisal fibers, all agricultural products are almost always looking for the market for the product, but sisal is the market to find products. In recent years, the market to open up particularly fast, such as paper and linen weaving, opera with a beard with sisal, because it is an environmentally friendly products, the use of the market more and more. Although the supply of sisal is very tight, but many investors see the deep processing of sisal profits, have to get involved in the sisal industry, focusing on the processing of sisal products on the project. Sisal wheel processing in Chaozhou is a highly competitive industry, because the processing program is relatively simple, engaged in a number of people.
Sisal wheel is mainly divided into two kinds: cloth sisal wheel and butter wheel.
The processing of cloth sisal wheel after four processes: 1, the arrangement of placement
2, sewing booking molding
3, set the center of the hole
4, cut edge
The cloth sisal wheel is made of five layers of sisal cloth, six layers of cotton cloth combination, the size of the 5cm-50cm, according to the requirements of customers, but the thickness of the sisal wheel shall not exceed 1.5cm. Not more than 1.5cm, its layout is a layer of cotton cloth a layer of sisal cloth spacing. Such work is relatively easy, usually done manually by female workers. Then use on the river brand sewing machine sewing bookbinding molding, followed by punching machine set the center hole, and finally cut the edge with a knife die set specifications size. The last three processes all need to use 20---30 lathe, and the sisal wheel is heavy, so these three processes are generally completed by male workers. Butter wheel is only made of six layers of sisal cloth, not allowed to mix with cotton. Size from 10cm - 45cm, depending on customer requirements, the thickness does not exceed 1.5cm. Its processing procedures are: 1, layout placement; 2, sewing staple molding; 3, set the center hole; 4, cutting edges; 5, varnish; 6, sun drying. The first four processes are the same as the processing of cloth and linen wheel, but with the last two processes: varnishing and drying. The cost of the butter wheel is higher than that of the cloth sisal wheel, so the selling price is relatively higher than that of the cloth sisal wheel by about twenty percent. My uncle has been engaged in the production and processing of sisal wheels for eight years, taking the road of "family-oriented" development, he treats his employees as his own family. Processing origin is only 300 square meters, the staff is only about 20 people, like a big warm family, management is flexible enough. Sisal wheel processing and production procedures are relatively simple and easy to manage. However, my uncle's requirements for sisal wheels are not simple, he believes that to win in similar products, we must enhance the core competitiveness of the product. First of all, we have to do not cut corners and do not speculate. In the raw materials, in each process to achieve perfection, to ensure product quality. His point of view is: first-class staff, first-class technology to create first-class products, only a high level, the quality of products to win the market. He has always insisted on "quality first, reputation first" as the service tenet. With "honesty and pragmatism" as the basic principle, the quality and price of the business philosophy to recruit the majority of manufacturers to occupy the market, to meet the customer.
But to compete in the market, you have to reduce production costs. And my uncle to reduce the cost of the method is through the various parts of the coordinated cooperation with the overall goal and the quantitative target of each stage, rationalize the arrangement of raw materials procurement, rationalize the arrangement of off-peak and peak season production. At the same time in the production process to save time, two-pronged approach. To achieve quantitative management objectives, management elements clear, production process programmed, production monitoring indicators. Based on the market and environmental conditions change, in order to strain, unconventional, adjusted at any time, as long as it works, do a good job, the effect is good, what methods can be used. These are my uncle's policy of production and management, but also his secret of invincibility in this industry. Data two: materials college 06 grade mold class Hisense mold company internship report: late July, materials science and engineering college 06 grade mold class 19 students began in Qingdao city Hisense mold company for fourteen days of internship. Different from the internship in other companies, Hisense gave enough attention to the interns, and the students were impressed by Hisense's fast-paced, organized and precise working style. The internship students were divided into five groups and took turns in the CNC area, electrician area, assembly area, general processing area and design department for one day's internship. As time was short, the students cherished the internship time very much and competed with the designers to learn and communicate with each other. In order to fully satisfy the students' desire for knowledge, Hisense also arranges evening training three times a week. The purpose of the internship in the CNC area was to understand the cavity structure, molding principles and processing methods. Students were also fortunate to see the cooperation project between Yamada and Hisense, i.e. molds using high-gloss technology, which is now becoming a trend in the home appliance industry. In the electrician area, it is mainly to learn and familiarize with the main machining required for electric machining and wire EDM to process parts that cannot be processed by CNC machines. In the field operation, consolidated the theoretical knowledge learned in the books, deepened the understanding of electrical processing is through the energized electrode on the workpiece corrosion in order to achieve the purpose of processing. And in the general processing area, the students visited and learned tool milling machine, gantry milling machine and other *** six different types of lathes, including horizontal and vertical milling machine. In the assembly workshop, highlighting group, polishing group and the highest technical content of the clamp group and other three large groups to make students eye-opening: highlighting group and polishing group are responsible for grinding the surface of the mold, so that its smoothness can meet the requirements, while the clamp group according to the drawings to install the various inserts of the mold. During the final design department, students learned about the general process of mold design, according to customer product drawings or models to get a three-dimensional solid model of the product, followed by mold structure sketch design and CAE analysis, to determine the layout of the gate program and injection molding process and other parameters, followed by the determination of the structure of the mold and the detailed design of the mold to get the mold solid model and the mold two-dimensional drawings, and then carry out NC programming, NC machining, EDM and other CNC programming. machining, EDM and other processing, and finally grinding and assembly. In the communication with the designers, in addition to learning the methods and process of mold design and the application of UG in mold design and other professional knowledge, the students also learned that mold design is a complex process in which experience plays a great role, in order to do a good job in such a job, we must continue to learn, accumulate, summarize, and have the spirit of hard work. During the internship period, the students mingled with Hisense staff, and Hisense mold company design department of the basketball friendly match, and Hisense soccer friendly match, to obtain further contact with Hisense staff opportunities, enhance each other's friendship. In the whole process of internship, the students learned what they could not learn in school for many years, which is a big step forward on the road to success. After the end of the internship, the students have to thank the team led by Mr. Guan Yanjin and provide internship positions Hisense Mold Company, hope that the friendship between Shandong University and Hisense will last forever.
