Plastic parts are a general term for spare parts with plastic as the main material. They are application-oriented and penetrate into different downstream application fields with rich product categories. They are an important part of downstream terminal products in terms of appearance, function, structure, etc. . Competitive landscape of plastic parts industry 1. Multi-dimensional competition in the industry, customer structure determines market position The molding process of plastic parts usually needs to be completed by molds, and plastic parts with different specifications, materials and performances are suitable for different molds. In order to ensure the quality of parts, molds need to be comprehensively considered in the process of design, development, and debugging. Material properties, Processing technology, processing equipment, production environment and other factors, and timely technical support to customers, so the plastic parts industry competes in multiple dimensions such as mold design and development, parts production and technical support. The multi-dimensional industry competition relationship makes plastic parts companies with leading comprehensive strength occupy a dominant position in the industry competition, while plastic parts companies with weak comprehensive strength compete fiercely in the low-end field. 2. There is sufficient competition in industry segments, and product quality is the key to competition Due to the complex and diverse types of plastic parts and the wide range of downstream applications, companies in the industry mainly compete in their respective sub-fields, and cross-field competition rarely occurs. Plastic parts need to meet the needs of different application scenarios, so they are mostly customized production, that is, custom-developed molding molds first, and then mass-produced according to the molds. This feature makes downstream customers pay special attention to quality factors such as plastic parts yield, durability, stability, etc., especially functional parts with high use value requirements, the quality of which directly affects the normal use of end products, and may even affect User security. Therefore, product quality competition has become the key to the competition of plastic parts companies in their respective subdivisions. The cooperation between plastic parts companies that have long focused on subdivisions and downstream customers is relatively stable, and customers' recognition and satisfaction with product quality determine plastic parts. The competitive position of the manufacturer in the market. 3. The market concentration is low, and the middle and low-end products are homogenized According to the statistics of China Plastics Processing Industry Association, there are currently more than 100,000 enterprises in my country's plastic products industry, with a total production value of plastic products of more than 2 trillion yuan. In 2018, there were 15,571 enterprises above designated size in my country's plastic products industry, of which there were 4,361 enterprises above designated size for plastic parts and other plastic products, and the market share of the top ten companies accounted for only 5% of the entire industry. Although the pace of structural adjustment in the industry continues to accelerate, the current plastic parts market is still dominated by small and medium-sized enterprises, and the core competitiveness of products is not strong.

The auto industry is picking up, and auto parts companies have orders until the end of June. Which companies will break out? After three consecutive years of decline, China's auto market will finally return to positive growth in 2021, with new energy vehicle sales increasing significantly. The recovery of the automobile industry has also brought a large number of orders to related parts companies. An auto parts factory in Chongqing now has a daily production capacity of more than 1,000 units, and orders have been placed in June. Among the track stocks, the callbacks of photovoltaics, lithium batteries, and wind power have all fallen to the vicinity of the annual line, which is indeed quite miserable! However, auto parts are relatively strong, and they stabilized after returning to the half-year line, and it was not so bad. So what are the factors behind this? The main reason is that the increase in auto parts itself is not large, and the model is similar to the shovel industry. As long as new energy vehicles are developing, there will be a lot of room for growth! Then, what about the next auto parts, we will analyze it from the perspective of industry logic and prosperity: 1. my country's automobile production and sales data ended the downward trend for three consecutive years. Before, due to the increase in prices of bulk, raw materials, and freight, the cost of the auto parts industry rose sharply. At the same time, the production and sales of the terminal passenger car market was under pressure due to lack of cores. This year The overall performance in the third quarter was poor. After entering the fourth quarter, automobile production and sales continued to recover. 2. The total sales volume in 2022 is expected to increase by about 5% year-on-year. According to estimates, the domestic sales of new energy vehicles this year will reach 5.5 million to 6 million! The data is considerable. The expectation of improvement in the downstream auto industry means that the auto parts sector is still highly prosperous. 3. With the advancement of the wave of intelligent electrification of automobiles, the industry order has been reshaped, and the next is the golden decade for the development of the automobile industry. The parts sector has ushered in opportunities, the traditional track continues to enjoy marginal improvements, and the new track provides sufficient performance. 4. The improvement in the supply of chips will bring about the demand for replenishment of the passenger car industry. In the future, with the recovery of the downstream economy, the industry will enter the replenishment cycle, and the industry replenishment will drive the revenue growth rate of the parts industry to rise. In addition, the cost of raw materials and freight has dropped, and auto parts are expected to become the main investment direction of the industry's next production cycle, and leading enterprises are expected to be born. Parts companies with greater operating leverage have greater flexibility in performance.

ABS plastic is a terpolymer of three monomers of acrylonitrile (A), butadiene (B) and styrene (S). The relative content of the three monomers can be changed arbitrarily to make various resins. ABS plastic has the common properties of three components, A makes it resistant to chemical corrosion, heat resistance, and has a certain surface hardness, B makes it have high elasticity and toughness, and S makes it have the processing and molding characteristics of thermoplastics and improve electrical properties. performance. Therefore, ABS plastic is a kind of "tough, hard and rigid" material with easily available raw materials, good comprehensive performance, low price and wide application. ABS plastic has been widely used in machinery, electrical, textile, automobile, aircraft, ship and other manufacturing industries and chemical industry.

1. General purpose plastic Generally, it refers to plastics with large output, wide application, good formability and low price. There are five general types of plastics, namely polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and acrylonitrile-butadiene-styrene copolymer (ABS). 2. Engineering plastics Generally refers to plastics that can withstand a certain external force, have good mechanical properties, high and low temperature resistance, and good dimensional stability, and can be used as engineering structures, such as polyamide, polysulfone, etc. 3. Special plastics Generally, it refers to plastics with special functions that can be used in special application fields such as aviation and aerospace. For example, fluoroplastics and silicones have special functions such as outstanding high temperature resistance and self-lubrication. Reinforced plastics and foamed plastics have special properties such as high strength and high cushioning. These plastics belong to the category of special plastics.

ABS has high strength and low density. Using it to make auto parts, such as bumpers, can reduce fuel consumption and reduce pollution. The high strength of ABS is because the nitrile groups on acrylonitrile have strong polarity and will aggregate with each other to bind the ABS molecular chains together. At the same time, polybutadiene with rubber properties gives ABS good toughness. Therefore, ABS resin is widely used, mainly used in automobiles, aircraft parts, electromechanical shells, air conditioners, refrigerators lined with typewriters, camera shells, TV shells, helmets, antenna amplifiers, car lights, plates, tubes, rods, etc. Among them, electrical products account for 40%.

The outer casing of the battery is used to hold the electrolyte and the plate group. The outer casing should be acid-resistant, heat-resistant and shock-resistant. It was mostly made of hard rubber in the past. Now domestic production of polypropylene plastic shells has begun. This kind of shell is not only resistant to acid, heat and shock, but also has high strength. The shell of the battery is used to hold the electrolyte and the plate group, and should be made of materials with acid resistance, heat resistance, shock resistance, good insulation and mechanical strength.

Lithium battery aluminum case is better than steel case. Although the price of aluminum shell is slightly higher than that of steel shell, but the resource supply is abundant, the construction scale is large, the technology is advanced, the environmental impact is small,Energy saving and emission reduction, high profitability. However, the steel shell has superior performance and high impact resistance. From the perspectives of market, technology, economy, engineering and other aspects of investigation, research and analysis,It will still dominate the market in the future.
