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.

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. Welcome relevant industries to communicate with us and look forward to our cooperation!
MDC Mould has rich experience in the production of SMC moulds. As a supplier of SMC moulds, it has many years of research in the design of SMC moulds and mold technology.
In this issue, let’s explore the reason why the front cover of the car adopts SMC mould.
The front cover of a car is an indispensable part of every car, but the material used is also very particular. Now on the market, more and more car front covers are made of SMC materials, so why can the front cover mold stand out? Let’s analyze it.
①Light weight of the front mask mold: Comparing with steel materials, composite materials can reduce the weight by 20-30%, but the stiffness and strength are similar, so people will naturally choose lighter weight.
②Excellent physical properties of the front mask mold: the mold material can maintain good strength and rigidity even under high temperature conditions, which can basically compete with aluminum alloy materials, and is an ideal material for replacing steel with plastic.
③Corrosion resistance of the front mask mold: SMC material itself is a corrosion-resistant material. At the same time, when this material is hit by an external force, the ability to rebound from the dents or depressions produced is stronger than steel.
④The front mask mold has heat resistance: this SMC material can maintain dimensional stability from -50 degrees Celsius to +200 degrees Celsius.
To sum up, there are reasons why SMC front mask are becoming more and more popular materials.

MDC Mould has rich experience in the manufacture of SMC molds and undertakes various projects. Lamborghini mentioned earlier and McLaren mentioned in this article, MDC Mould are involved.
In the last issue, the editor introduced the application of SMC moulds on Lamborghini, and in this issue, we invite our “grand guest” – McLaren.
McLaren is also one of the top supercar brands in the world. Its well-dressed appearance hides a violent heart. The gorgeous appearance and its uniqueness always make many people fascinated by it. I don’t know much about the car research, but when I saw it for the first time, I was attracted by its two doors. The scissor-like shape is light and stylish. I can’t help but wonder what kind of material makes it light. Free and easy?
Later I realized that this is the credit of the SMC mould. We have mentioned the characteristics of the SMC mould many times before. It is relatively light in weight, heat-insulating and corrosion-resistant, light in weight and high in strength. In addition, it has a large degree of freedom in product design. Therefore, it is regarded as a favored material in the automotive industry, and SMC molds are also widely used.
At this point, readers should also be able to understand that the McLaren mentioned above actually uses the SMC mould properly to bring a different experience to our customers.
MDC Mould has rich experience in the manufacture of SMC molds and undertakes various projects. Lamborghini mentioned earlier and McLaren mentioned in this article, MDC Mould are involved, with a wide range of businesses and far-reaching scope. Welcome to contact us.
The body shell of Lanborghini uses SMC molds to meet its required strength and rigidity, and the cool sound of the sports car also benefits from this.
For all of us, Lamborghini is one of the top sports car brands in the world. So why did I mention it today?
Lamborghini, the lines are rigid and stylish, and each model is exquisitely crafted. The character, history and temperament of the car model can be perfectly reflected in the appearance. What impresses us the most is the “swish” sound that it “speeds” past in front of us, which is different from the sound of other ordinary cars, giving people a full sense of luxury!
So the question is, what is the uniqueness of Lamborghini? Here, the editor has to mention SMC mould.
SMC mould is one of the types of molds for thermocompression molding process. SMC mold requires a heating system for the mold cavity and core, and the temperature difference is kept at about 5 degrees Celsius. After the process parameters are set, put the sheet mold material in the mold, close the mold, and use the set temperature and pressure to melt the raw material into the mold cavity for molding.
SMC has the advantages of light weight, high strength, and no rust. It is an excellent material for manufacturing products, so SMC molds are widely used in the automotive industry.
As for the Lamborghini we mentioned earlier, its body shell uses SMC molds to meet its required strength and rigidity, and the cool sound of the sports car we mentioned also benefits from this.
As a SMC mould supplier, MDC Mold has many years of research in the design of SMC mould and SMC mold technology, and has a supporting mold trial line for SMC mould to ensure that SMC mold is from the original design. To follow-up mass production to meet customer needs.
