We college students have spent most of our lives in school, so our understanding of the outside world can only be superficial at present. But can we wait until we get out of school to get to know the society better? Obviously not. If you go to the society with rigid book knowledge, you will inevitably hit a wall everywhere and delay your outstanding youth. I want to be an intern in the factory and get in touch with society during my college years. Only when we have a deeper understanding of practical things can we consciously learn more useful things for society during our college years, so that we can adapt to society more quickly and serve the people better after leaving society. So, on April 2006 10, our class 03- 1 started a one-week factory internship.

Training purpose:
In order to meet the needs of practical work in the future, to get in touch with the broad society and enrich our knowledge and experience. It's a good idea to be an intern in a factory. One of the most striking features of Marxist philosophical materialist dialectics is its emphasis on practicality. The main purpose of this internship is to let me better understand the production process of some products closely related to my major. For example, understand the process and structure of hollow blow molding and injection molding and the specific production process of tires and other products.
Training content:
On Monday afternoon of April 10, our first stop was Maoming Golden Eagle Canning Factory in our school.
First, the person in charge of the factory told us about the production principle and technology of hollow blow molding machine and injection molding machine.
The production principle of hollow blow molding machine: the polyethylene raw material is put into the blow molding machine, heated to a molten state, and then the tube blank is extruded from the right-angle die of the blow molding machine. When the tube blank reaches the required length, quickly close the mold, cut off the tube blank, and inject compressed gas into the tube blank to make the tube blank expand in the mold.

In the factory, we also know the shape of raw materials, such as high-density polyethylene and red masterbatch, as well as production equipment, such as crusher and color mixer. Also know some production parameters and mixing ratio.
In the conversation with the production workers, I also learned that their daily output is around 1000. I work eight hours a day. The products produced are mainly used for loading lubricating oil.
On the morning of Tuesday, April 1 1, 2006, our second stop was Gaozhou UFO Tire Industry Co., Ltd.
First of all, the company leaders gave us a brief introduction to the company. The following are some profiles about the company I found on the Internet: UFO Company is a key enterprise producing motorcycle tires and motorcycles in China, with advanced tire equipment and testing equipment; Annual production capacity of motorcycle tires and bicycle tires 10000 sets or more; There are more than 80 kinds of motorcycle tires, such as ordinary tires, reinforced tires, vacuum tires and self-repairing tires, which are three series: yard, metric and small wheel diameter. Bicycle tires include ordinary tires, reinforced tires, high-quality tires, straight-edged, crocheted-edged and soft-edged colored tires 100. The company has more than 30 years of tire production experience, and the "Flying saucer" brand tire has passed the national "CCC" compulsory product certification, and has been rated as provincial excellent, ministerial excellent and national A-class products, and one of the "Top Ten Industrial Brands" in Maoming City.

Next, I visited the production process of the factory and learned from the team leader that the main raw material of tires-high-quality natural rubber is directly supplied by Thailand Rubber Company; UFO Company and Maoming Yongye Company joined forces, and Maoming Yongye directly supplied high-performance N234 carbon black as tire reinforcing material, making the products more wear-resistant and load-resistant. UFO company introduced AUTO-CAD technology to design tires, which greatly shortened the development cycle of new products and improved the product accuracy. UFO company adopts international advanced production technology: high-precision forming spring; Computer automatic control of vulcanization: the internal mixer adopts rubber film-dissolving packaging and automatic feeding; The calendering adopts a high-precision four-roll calender with automatic adjustment to calender the composite adhesive; In rubber processing, biological solidification technology is used instead of acid solidification, which fundamentally ensures the excellent properties of rubber.
In April 2006, five branches of Guangdong Maoming Zhonghe Plastic Co., Ltd. were awarded the first batch. 12 and no 14.
They are Maoming Zhonghe Guyuan Polymer Materials Company Chemical Plastics 1 Factory.

During the two-day internship, we learned more things, which can be said to greatly broaden our horizons.
1. From it, I learned that replacing wood with plastic-wood composite materials can not only reduce the demand for wood in China in the future, save a lot of forest resources, but also alleviate the increasingly serious white pollution problem in China. It provides a new way for the comprehensive utilization of solid waste. It is an environmental protection project with the sustainable development characteristics of comprehensively developing waste resources and turning waste into treasure, with high economic and social benefits. At present, plastic-wood composites have been widely used in civil and commercial fields such as construction, decoration, packaging, transportation and storage.
2. The communication cable sheath product is a special resin for linear ethylene cable produced by UCC technology, which is mixed, plasticized and granulated by adding carbon black and various additives.
3. The woven bag products are made of high-quality products produced by Maoming Ethylene, and are carefully processed with advanced equipment and technology.

This product has the characteristics of high strength, firm packaging, moisture-proof and waterproof; And has beautiful appearance, easy palletizing, convenient handling and transportation and low packaging cost. Suitable for packaging solid materials such as chemical products, fertilizers, feed, grain, cement and ore.
4. Styrene-butadiene transparent impact resin has become the fastest developing high-tech material in the 20th century because of its excellent properties such as transparency, impact resistance, non-toxicity, high gloss, easy processing and easy mixing with other polymers. Widely used in packaging, medical equipment, home appliances, toys, shoes, high-end daily use and office supplies and other fields. Its film has the advantages of high transparency, rigidity, flexibility and brightness, and is widely used. Another important application is to modify various plastics, such as GPPS, SAN, PP, etc. , made into plastic alloys for various purposes, has great development potential. The product can be processed by injection molding, sheet extrusion, thermoforming, blow molding and cast film extrusion.
Apprenticeship experience:
Although it is only a week, I still feel that I have gained a lot. I feel deeply that theoretical study is the basis of actual combat, but how different the actual work is from theoretical exposition. After work, in conversations with some workers who have worked for many years, I know that good business ability is the basic ability at work. Therefore, it is particularly important for us college students to master solid professional knowledge.
I suggest reading carefully.
Another point is not only to maintain the quality and efficiency of work, but also to be innovative in their relatively repetitive work.
Seeing that some packaging bags in a factory are printed in English, I can basically understand the general meaning, but I still can't understand some professional words. Hehe, I finally realized the importance of polymer English.
In the process of internship, I learned a lot of things that I can't learn in textbooks, which can be closer to society and enterprises. I also found my own perspective on the problem, and the way of thinking about the problem has gradually developed, which is inseparable from practice. During my internship, I once again felt enriched and growing.
