SMC Mold and New Energy Vehicles

New energy vehicles are the future development trend of the automobile industry. SMC molds provide important support and solutions for the manufacture and development of new energy vehicles.

In 2022, the world is still under the influence of the epidemic, and many industries are swaying in the wind and rain. Even if the economic conditions are down, there is one industry in the world that is growing rapidly, which is new energy vehicles. As consumers’ demands for environmental protection, energy saving, and intelligence continue to increase, new energy vehicles are the future development trend of the automotive industry. But while environmental benefits are a motivating factor for EV adoption, vehicle performance and technology are the main draw. The improved driving experience brought about by technological progress, design and styles are all key factors in the popularity of electric vehicles. Especially for ordinary people, the most important advantage of new energy vehicles is not environmental protection, but low travel costs, and electricity bills are much cheaper than fuel bills.

Compared with traditional metal materials, composite materials manufactured by SMC molds(sheet molding compound) have the following advantages:

1. Lightweight: Composite materials made by SMC molds are lighter than metal materials, which helps to reduce the weight of the vehicle and improve the mileage and energy-saving effect of new energy vehicles.

2. High strength: The composite material made by SMC mold has high strength and rigidity, which can improve the impact resistance and tensile resistance of the body, and improve the safety of the vehicle.

3. Corrosion resistance: The composite material made by SMC mold is not easy to be corroded, which can ensure the long-term stability of the body and components.

4. Good shapeability: SMC molds can produce complex body and component shapes, have better shape performance, and can meet the design requirements of new energy vehicles.

5. SMC molds can also realize automated production through digital manufacturing technology, improve production efficiency and quality, and realize intelligent manufacturing, which will help promote the modernization and intelligence of new energy vehicle manufacturing.

Therefore, SMC mold provides important support and solutions for the manufacture and development of new energy vehicles.

According to the statistics, China is already the world’s largest market for electric vehicles, and it also leads in terms of infrastructure. There is no doubt that China is ahead of the trend.

Will Composite Material Decouple?

As an important material, will composite material decouple?

Composite material is an important material, which has been widely used in aviation, aerospace, automobile, construction, electronics and other fields. Parts made of composite materials have high strength, light weight, and high rigidity. The Jeep car of Chrysler Group Co., Ltd. and the “Seastar” CD2 aircraft of Dornier Starfish Malaysia all use advanced composite materials such as SMC molds and carbon fiber composite materials.

But the manufacture of composite materials usually requires raw materials, technologies and equipment from many different countries or regions, so international cooperation and trade are inevitable.

However, under the current international situation, factors such as politics, economy, and security among countries may lead to decoupling among countries. For example, some countries may adopt protectionist policies, restrict the export of raw materials and technologies, or impose trade restrictions on products from certain countries. These constraints can have implications for composite manufacturing and supply chains, affecting product quality and cost.

In addition, some countries may restrict or prohibit the import of specific products or technologies from certain countries, which may affect the manufacture and application of composite materials. For example, when security or privacy concerns arise in certain countries, electronic products or technologies from that country may be restricted or prohibited from entering other countries’ markets.

Therefore, composites may be affected by decoupling and trade restrictions between countries. This requires companies and manufacturers to take corresponding measures to deal with it, such as dispersing production bases among multiple countries, exploring alternative raw materials and technologies, and strengthening quality management and testing.

Applications of SMC mold in Rail Transit

As a lightweight material, SMC mold can be used in the production of train auxiliary parts, non-main bearing parts, carriages, car bodies, bogies, power rail bearings, etc. in rail transit.

The rapid development of high-speed railway industry in China’s rail transit has attracted worldwide attention. However, in recent years, energy shortage and environmental pollution have become the focus of global attention. Energy conservation and emission reduction are becoming the common choice of economic development of all countries in the world. Lightweight is an important means to achieve energy conservation and emission reduction, and it is also an inevitable trend in the development of transportation. The development of lightweight materials is the key to lightweight rail transit. Lightweight materials are divided into aluminum alloy, composite material and plastic. Composite materials have become the main materials.

Among all fiber reinforced resin materials, SMC materials are the closest to metal materials in performance. Although molding processing cycle of SMC molds is longer than that of metal metarials, SMC molding equipment has less investment and can be continuously produced with higher automation. At the same time, compared with other fiber reinforced resin materials, SMC mold has the advantages of short molding cycle, uneasy deformation of products, high mechanical properties and thermal stability, and strong corrosion resistance.

In rail transit, SMC mold can be used in the production of train auxiliary parts, non-main bearing parts, carriages, car bodies, bogies, power rail bearings, etc.

MDC Mould is mainly engaged in the development and production of hot-pressing molds such as SMC mold, BMC mold, GMT mold, FRP mold, etc. The molds developed by our company have high level of technique, long service life, short cycle, reasonable price, timely delivery and considerate service, which are favored by customers at home and abroad.

the Mold Industry Now in China

In recent years, due to various reasons, the development of the mold industry has faced many difficulties. It is not as easy as before, and the future development prospects are not very clear. At last, many people have to leave the industry.

The first objective reason is the market environment. However, the development of everything is cyclical. The current trough is only temporary. The overall trend of China’s economy will not change. Therefore, the difficulties caused will be gradually eliminated in a short period of time in the future. Therefore, there is nothing to worry about this factor. Moreover, the economic downturn affects not only the mold industry but also the manufacturing industry. Most industries are all affected.

Moreover, the mold industry is the basic industry. Mold is indispensable to industry, just as catering is to people’s livelihood.

In fact, a subjective factor within the industry should account for these difficulties. Attracted by the explosive profits in the mold industry in the early period, different sizes of processing shops, mold factories and consumable stores have sprung up, and the number of mold companies has almost doubled. The industry itself is expanding too fast, and even if the economy is booming, there will be fierce competition. However, unfortunately, it encountered economic downturn, and difficulties arose.

At this time, some companies insist on quality and do not engage in price war, while some companies compress equipment and labor in order to save costs, resulting in a vicious circle, which eventually leads to closure. The closing of a company may have a chain reaction, leading to the crisis of several companies.

MDC Mould was established in 1997, mainly engaged in the development and production of hot-pressing molds such as SMC mold, BMC mold, GMT mold, FRP mold, etc. In the future, the company will focus on the development of higher quality and high-tech molded FRP molds. We adhere to the concept of professionalism and integrity, establish long-term and mutually beneficial partnership with customers, and become the pioneer of customer development projects through professional technology and thoughtful services.

SMC VS BMC

MDC mould is a professional supplier of SMC and BMC materials. Do you know what are the differences between them?

SMC and BMC, They are just like twins.

They are both a kind of resin mixture, which will be made into semi-finished products before molding. But at this time, BMC is made into clumps, while SMC is made into matte flakes, which are then cut to size.

The production process of SMC mold and BMC mold is also different. SMC molds are usually formed by compression molding, while BMC molds can be formed by different forming ways like injection, compression molding or transfer molding. These methods can all meet the production needs of medium and high volume.

Although the raw materials of SMC and BMC are roughly the same, there are differences in the use of glass fiber between the two materials. Glass fiber reinforced materials added to SMC generally account for up to 30%, and the fiber length is usually 25~50mm. In BMC, glass fiber reinforced materials generally account for 10%~30%, and the fiber length is usually 6~24mm. In comparison, the length of glass fiber used in SMC is longer than that used in BMC. Therefore, there are some differences in performance between these two. In general, SMC mold is stronger than BMC mold. In BMC molds, mineral fillers have a higher specific gravity and thus lower cost.

The advantages of SMC mold:

●Lightweight and high strength: With the same volume of materials, SMC is lighter than steel and aluminum, and its relative density is generally 1.3~2.0g/cm3, only 1/4~1/6 of ordinary steel, and 1/3 lighter than aluminum alloy. It can achieve the goal of lightweight, and has good impact resistance and energy absorption, and has high tensile strength, bending strength and impact toughness.

●High degree of integration and large degree of design freedom: The flow characteristics and molding process of SMC materials determine that many parts can be molded at one time, which can reduce the number of molds, tooling and the number of steps in the welding, assembly and other processes, thereby significantly reducing costs and realizing low-cost actions for low-volume components.

●Strong corrosion resistance: SMC material itself is a corrosion-resistant material, so it does not need phosphating treatment for anti-corrosion and improved bonding performance. Compared with metal, the application of SMC mold can reduce cost and save energy.

●Excellent heat resistance and paintability: SMC products have good heat resistance. After demoulding, SMC products can maintain dimensional stability at -50-200°C. Excellent heat resistance makes it suitable for use in auto parts. In addition, SMC material is the most suitable material for steel plate spraying technology. SMC has a thermal expansion coefficient and heat resistance similar to steel, and the sprayed SMC products can be cured at the same oven temperature as steel.

●Easy molding process: The molding of SMC molds mainly adopts metal-to-mold compression molding at present. The process is relatively simple. Cut the SMC sheet into the required shape and determine the number of layers to be added, then remove the protective film on both sides, stack it according to certain requirements, and place it on the appropriate position of the mold. Then it can be heated and pressurized according to the specified process parameters.

The advantages of BMC mold:

●Dimensional stability: The coefficient of linear expansion of BMC is smaller than that of ordinary thermoplastics, which makes BMC mold have high dimensional stability and dimensional accuracy.

●Good resistance to water and solvents: BMC has good corrosion resistance to water, ethanol, aliphatic hydrocarbons, grease and oil. Meanwhile, BMC has low water absorption, and its insulation performance is still good after soaking for one day.

●High heat resistance: The heat distortion temperature HDT of BMC is 200~280°C, and it can be used at 130°C for a long time.

●Aging resistance: BMC mold has very good aging resistance. It can be used indoors for 15-20 years, and its strength retention rate keeps above 60% after 10 years of outdoor exposure.

●Excellent electrical performance: Excellent arc resistance is the most outstanding advantage of BMC, which can reach about 190s.

In general, when the requirements for the mechanical properties of the products, including tensile strength, bending strength and impact strength, etc. are higher; when the requirements for the surface area of the products is larger, and when the requirements for the lightweight of the products is higher, SMC will be selected.

In general, the requirements for the mechanical strength are lower than SMC but the cost need to stay low; when the requirements for the electrical properties and flame retardant properties of the products are higher; or when the requirements for the surface area of the product itself is small, people usually choose BMC.

Excellent Application of SMC Moulds on Blind Roads

MDC Mould already has advanced technology and rich experience in using SMC moulds to produce blind roads, and has been widely used in the market.

When it comes to the blind road, I believe that most people will not feel unfamiliar, because we will find that we can often see its existence in life. In this world, not everyone can be lucky, with healthy limbs and a healthy body. There are always a group of people who are different, and their world is less bright and colorful. The blind road can be said to be a little warmth for them, making them feel the care of the society.

Turning back to the topic of the blind road, what kind of existence does it have, so that the blind can distinguish other roads? You can take a look at the picture below.

Features of the blind path: The blind path is generally paved by two types of bricks, one is strip-shaped guiding bricks, which guide the blind to move forward with confidence, which is called the walking blind path; A turn is called a prompt blind road. The blind road with yellow protruding stripes looks like the static eyes of the blind. It is paved on the sidewalk of the road and set up for the convenience of the blind. Bricks with special shapes and bright yellow colors are achieved by using the sense of feet of the blind and the principle of assisting sensation of tactile bricks.

At present, there are various materials for blind walkways, among which cement, stainless steel, plastic and so on are common. Among them, the price of cement tactile bricks is relatively cheap. This kind of tactile bricks is made of cement. There are many holes in the brick body and high water absorption, but the compressive strength is low and the service life is short; The bricks are thin, easy to deform, and the surface is smooth after a long time of use, which is likely to cause safety hazards to pedestrians; while plastic plastic tactile paving bricks are plastic products, the bricks are thin, not resistant to rolling, easy to crack and deform, and have a long service life short.

Today we are going to mention the blind roads made of SMC materials. To sum up, the blind roads made of other materials have more or less shortcomings, but the blind roads made of SMC moulds have advantages that other materials that cannot be compared. It has light weight, good strength and toughness, excellent drainage performance, safety and environmental protection, long service life, low production and maintenance costs, can realize mass production, and is widely used in the laying of blind roads and road warning lines.

Blind road construction cannot be ignored, it is a kind of humanistic care, SMC mould is the best choice for pedestrian blind road. At present, MDC Mould already has advanced technology and rich experience in using SMC moulds to produce blind roads, and has been widely used in the market.
