Introduction to New Energy Vehicle Production


Recently, data from the China Automobile Association showed that from January to March this year, the cumulative sales of new energy vehicles were 1.257 million, a year-on-year increase of 138.6%. At present, new energy vehicles are the development trend of the automobile industry, and plastic materials play an important role in promoting the lightweight of new energy vehicles and the production of special parts by virtue of their performance advantages. The automobile industry has become one of the fastest-growing areas of plastic demand, mainly due to the steady growth of global automobile production and the lightweight of automobiles, which has led to an increase in the use of modified plastics.

Lightweight is an important factor restricting the development of new energy vehicles. However, with the application of high-functional plastic materials such as PPS engineering plastics in automobiles, the lightweight problem of new energy vehicles has been alleviated to a certain extent.

The plastic parts used in the production process of new energy vehicles include interior and exterior trim parts, dashboards, lights, fenders, pedals, motor insulation parts, DC converters, IGBT power modules, and electronic water pumps. PPS plastics can be seen in many important components such as lithium batteries and lithium batteries.

Plastic parts of new energy vehicles usually need to have high temperature resistance, UV protection, anti-static, corrosion resistance and other characteristics. In addition, these injection molded parts also need to have excellent mechanical strength and stability to ensure the safety and stability of the vehicle.

Plastic accessories can not only effectively reduce the weight of the car body, increase the cruising range of the car, but also reduce the manufacturing cost of the car company. For example, some parts with complex structures and difficult processing that require the integration of multiple steel parts can be directly produced by PPS injection molding, which greatly reduces the number of parts used. In addition, the elastic deformation characteristics of engineering plastic products can absorb a large amount of collision energy, have a great buffering effect on strong impacts, and have a good protection effect on vehicles and passengers; engineering plastics are highly resistant to chemical corrosion, and local damage will not corrode For example, PPS plastics are not corroded by most acid-base salts except for strong oxidizing acids. Once the paint surface of steel is damaged or the early anti-corrosion is not done well, it is easy to rust and corrode, which not only affects the appearance of the car body, but also Form a safety risk; according to the tissue composition of the plastic, engineering plastics can be modified by adding different fillers, plasticizers and hardeners to prepare the required plastics, and enhance the mechanical strength and processing properties of the plastics, etc., to meet the needs of different vehicles. Component usage requirements. For example, PPS plastic is reinforced with carbon fiber, and the modified PPS material can be used to produce automotive electronic water pumps, which perfectly meets the high requirements of water pumps for high wear-resistant and high-strength materials.

Hengju central conveying system can greatly reduce the production cost of plastic enterprises; Hengju central feeding system creates an automated intelligent digital factory, realizes uninterrupted unmanned continuous molding operations, optimizes the operation of the production workshop, and improves the efficiency of machinery manufacturing Efficiency and product quality, cost reduction and efficiency increase.

The storage and feeding system is fully automatic control, the system is easy to operate, and only a small number of personnel are required to complete the feeding action of the plastic molding equipment. The central console can control multiple molding equipment, and can also monitor the working status of the system in real time. The usage of materials, product yield, equipment startup status, and production status are easy to track at a glance.

According to the needs of customers, we can provide personalized central feeding schemes. Different workshop characteristics and different raw material usage requirements can design optimal solutions according to actual needs, so as to meet and optimize the production process of customers.

Our factory, Hengju Machinery, actively responded to the country’s policy of vigorously supporting the upgrading and transformation of plastics enterprises. For plastics production enterprises, we launched the “Enabling 100 Enterprises” plan for the digitalization, intelligence, and unmanned operation of the plastics manufacturing industry. 1,000 plastic production enterprises quickly completed the digital, intelligent, and unmanned upgrading and transformation of production workshops.

In the context of the rapid growth of the new energy vehicle market, suppliers and manufacturers of injection molded parts are actively seeking innovative materials and production technologies to meet the growing market demand. At the same time, the government and industry organizations are also promoting the development of related technologies to support the development of the new energy vehicle industry.
