New material solutions for automotive plastics are available at CHINAPLAS

According to statistics, in 2014, China's automobile production and sales were 23.72 million and 23.49 million, respectively, an increase of 7.3% and 6.9%, ranking first in the world for six consecutive years. As the most promising lightweight material, plastics are increasingly used in automobiles. Internationally, the average plastic used per car has exceeded 150kg, accounting for nearly 10% of the total weight of the car.

CHINAPLAS 2015, which will be held in Guangzhou on May 20-23, brings together the world's top materials and technology solutions, and will showcase high-performance plastic materials to provide an effective way to reduce weight. It is worthwhile for the industry to explore exactly.

Recently, the "Management Requirements for Hazardous Substances and Recyclable Utilization of Automobiles" (referred to as "Requirements") has been completed and the news has promoted the "green" development tone of the industry to be further strengthened. The "Requirement" proposes that automobile production enterprises, as the main responsibility of pollution control, should actively carry out ecological design, adopt reasonable structure and functional design, and choose non-toxic and harmless or low-poison green materials and easy to disassemble and utilize. Parts, application of green resources with high resource utilization, low environmental pollution, and easy recycling. After the "Requirements" is issued, automobile manufacturers will put forward higher requirements for parts companies and automotive materials suppliers in the use of environmentally friendly materials and green manufacturing technologies.

The main sources of formaldehyde in the air of the car are PU seat and steering wheel, PVC artificial leather skin and adhesive; acetaldehyde is mainly from PU material seat, interior panel, steering wheel and adhesive; Toluene comes from PP, PVC parts and paints.

Ways for car manufacturers to improve the air quality inside the car

First, low-emission environmentally friendly interior materials can be used. Some car OEMs have already begun to take action. For example, Volvo, known for its “northern clean air in the car”, has placed almost stringent demands on the materials used in car interiors. Its domestic models VOLVO S60L and XC60 use Shanghai Jinhu Ri Li's Plastic Cleaner® as the interior plastic. The product has been rated as the lowest automotive interior plastics by the third-party authorities, with a TVOC content of less than 10μgC/g. More than 60% lower than traditional interior plastics. Plastic net will be unveiled at the CHINAPLAS booth. In addition, IonPhasE®, a new environmentally friendly static dissipative additive produced by Aonfei

IPE® will also be on display, which is compliant with the EU RoHS Directive and WEEE and is completely halogen free.

Secondly, choose high-gloss and matte-free spray-free plastics, such as ABS, PC/ABC, PA/ABS, PA/ASA and PC/ASA, to effectively reduce the infection of benzene series such as xylene.

In addition, in-film inlay molding process can be adopted instead of paint spraying; or integral structural parts can be used to replace multiple small parts to reduce the amount of adhesive, thereby reducing formaldehyde and acetaldehyde infection in the car.

Another plastic exhibitor of CHINAPLAS, Polyplastics, developed a heterogeneous resin material joint forming technology that can be used in automotive hybrid powertrain components to reduce the use of adhesives. This new technology will be provided free of charge to customers, thereby expanding its resin materials business. .

The use of high-strength, high-performance plastic materials for vehicle weight reduction is also an effective way to reduce the carbon footprint. Some car manufacturers have begun to work on special systems made of carbon fiber and matrix. To cater to this trend, the new composite system research conducted by CHINAPLAS exhibitor BASF and SGL Group was successfully completed. The composite is based on activated polyamide system and compatible carbon fiber. The carbon fiber surface is designed for the matrix system. (or sizing agents) and custom thermoplastic reaction systems mean that lightweight structural components can be easily produced in industries such as automobiles.

Some Chinese suppliers of modified plastic raw materials have successfully entered the supply chain of internationally renowned automakers, such as Zhejiang Juner New Materials Co., Ltd., which produces high-end bumper materials with high impact, high rigidity and high flow. Hard indicators such as sex, low shrinkage, and low linear expansion coefficient are favored by BMW and replace the materials imported from Europe. They are used in automobile bumpers and have been successfully applied to BMW 3 Series, 5 Series, X1 and other models. At that time, the audience will be able to see the high-end "particles" at the exhibition site. In addition, well-known companies such as Teijin Group, Taishan Glass, Roquette, Solvay, Shin-Etsu, Premarin and Milliken will also exhibit their fist products.

In short, to achieve the "green" development of the automotive industry, we need to start from the source, choose to use environmentally friendly materials and processing equipment with the least loss of energy, least waste, and low toxicity, and strictly control all aspects.

"Automation" surge

Some research reports indicate that strengthening automated production is the business strategy of the most manufacturers in the next 3-5 years. The market is increasingly demanding product quality. The biggest challenge is how to help customers achieve the highest quality and lowest unit cost to meet the increasing quality requirements of the market. One of the keys to solving this problem is to have customized device concepts, process integration and automation. In addition, with the aging of the population, manufacturing industries, including the automobile industry, are generally faced with the problem of “difficulty in employment”, and upgrading automated production has become the only choice for enterprises to reduce labor costs. For example, to save costs, BYD has purchased more than 10,000 smart devices a year, because 100 machines require 50-100 operators and managers, and robots can use more than one machine; Chrysler plans to invest $2 billion to upgrade cars. Automated production line, the investment includes the construction of more than 860 new automotive assembly robots, 800 flexible production lines and the transformation of more than 80% of the overall assembly area.

Quality component production depends on reproducible cycle operations, which can only be achieved through automated operations. As an integrated device in the plastics processing process, automation can only support new production processes, component functions and product quality, in order to enhance the market competitiveness in essence. Therefore, in China, robots are increasingly becoming a fixed component in injection molding machine equipment. ENGEL will present its full range of robots in CHINAPLAS 2015's new "Industrial Automation Zone", and the new e-pic pick-and-place robot will celebrate its Asian debut, which will facilitate easy part removal, Slag separation and control of precipitation, mesh precipitation, and stacking of small parts; requires less space for injection and clamping units than conventional linear robots; can be integrated into the safety boundaries of injection molding machines To make the entire production unit more compact. The CHIANPLAS audience can also see the ABB robots on the spot. According to reports, ABB robots rank first in the global automotive industry. Changan Ford has increased production efficiency by 30% through ABB's fully automated welding shop solution. On this line, six different models are produced in line, allowing one car per minute to go offline.

The exhibition also brought together many “upper” equipments in the industry, such as: Zhongshan Lijin Machinery's two-plate injection molding machine for the automotive industry's special molding system, suitable for automotive parts (lights, dashboards, bumpers), etc. Large injection molded parts. The large-scale injection molding machine of Zhenxiong Superba is especially suitable for the production of large and deep cavity products. Fuqiang Xin machine has a clamping capacity of 350 tons of HB-350RV, which is enough to cover the capacity of the traditional 1,000-ton two-color machine. By then, 3,200 sets of machinery and equipment will compete for you, and there will always be a choice for you.
