Fiber-reinforced polymer (FRP) composite materials are defined as polymers reinforced with fibers, representing a category of materials falling under the broader classification of composite materials. Composite materials are formed by dispersing particles of one or more materials into another material, creating a continuous network around them.

FRP composite materials differ from traditional building materials like steel and aluminum. FRP composite materials are anisotropic, whereas steel and aluminum are isotropic. As a result, their properties are directional, meaning the optimal mechanical performance occurs in the direction of fiber placement.

These materials exhibit a high strength-to-density ratio, excellent corrosion resistance, and convenient electrical, magnetic, and thermal properties. However, their brittleness may impact mechanical performance depending on load rates, temperature, and environmental conditions.

Primary Function of Reinforcement: The primary function of reinforced fibers is to bear loads along the fiber length and provide strength and stiffness in one direction. In many structural applications where load-bearing capacity is crucial, FRP composites have replaced traditional metal materials.

Components of Composite Materials

SMC(sheet molding compound) mould has excellent corrosion resistance, soft quality and easy engineering design, flexible and other advantages. Its mechanical properties can be compared with some metal materials, and the products manufactured by it have the advantages of good rigidity, deformation resistance, and wide temperature range. SMC molds require heating channels instead of cooling channels in injection molds. Normal heating systems are steam, oil, electricity or high pressure water. The working temperature of SMC mold is usually 140 degrees to 160 degrees. When designing the temperature system, it is necessary to keep the mold surface at a close temperature. Molds with uniform temperatures will fill more easily and produce parts with less warpage, improved dimensional stability and a uniform surface appearance.

In the process of mold processing, different mold materials and shapes will affect the heating method, and different heating methods will also have different effects on the performance and processing efficiency of the mold. This article will introduce in detail the common mold heating methods, their respective characteristics, applicable scenarios and their impact on SMC molds.

Electric Heating

Electric heating is a mold heating method commonly used at present. The electrothermal effect occurs on the surface of the mold by electrification, thereby heating the mold. It can be achieved by heating rods, convection heating and other different ways. Electric heating has the advantages of simple operation, fast heating speed, uniform and stable heating temperature, high temperature control accuracy, and no need to wait for heating or cooling time. It is suitable for mold heating of all materials. At the same time, electric heating can also realize the control of different temperature regions through the adjustment of heating elements, so as to realize different processing schemes and patterns. However, electric heating has a relatively large demand for electricity, and the cost of using an electric heater is also relatively high.

Electric heating is often used for heating plastic molds, especially for molds that require high precision, such as SMC molds. Compared with traditional heating methods, electric heating can control the mold temperature more precisely, so that the manufactured molds are more accurate and the shell quality is higher.

For SMC moulds, electric heating can help speed up the mold heating speed and temperature rise, thereby reducing manufacturing time, speeding up production rhythm, and improving production efficiency. performance, thereby ensuring the service life of the mold. Electric heating can also increase the hardness and strength of SMC composites, thereby improving the performance and quality of products. However, there are some factors that need to be paid attention to when using electric heating, such as the reasonable setting of voltage and current, and the control of heating time and temperature, so as to avoid affecting the performance and service life of the mold and damaging the mold.

Steam Heating

Steam heating means that steam is transported into the mold through pipelines for heating. The temperature control of steam heating is more precise, and the heating speed is relatively fast. Steam heating is suitable for molds with complex and irregular shapes and needed temperature is not too high. However, steam heating requires a complete steam pipeline and supporting equipment. This method is more energy efficient than electric heating, but relatively consumes more energy. Steam heating is a commonly used mold heating method. Its basic principle is to use the heat energy of high-temperature and high-pressure steam to contact the mold, thereby increasing the temperature of the mold to meet the processing requirements.

This heating method has the following characteristics:

1. Uniform heating: Steam can be evenly distributed on the surface of the mold, so that the entire mold is heated evenly, avoiding thermal stress caused by excessive temperature gradient.

2. Efficient and safe: The steam heating speed is fast and the efficiency is high. At the same time, because there is no open flame in the steam heating process, it has higher safety.

3. Precise temperature control: When steam is heated, sensors can be used for real-time monitoring and adjustment, so as to achieve precise temperature control.

Steam heating is widely used in plastic molds, die-casting molds, rubber molds, etc., and can also be used for preheating and annealing of metal molds.

For SMC molds, SMC molds are usually made of composite materials, which have high strength and corrosion resistance, but there are also some shortcomings, such as thermal stress and surface adhesion. The uniformity of steam heating and the accuracy of temperature control can effectively solve these problems, avoiding the thermal stress caused by the local temperature being too high or too low during the heating process. At the same time, steam heating can also promote the fluidity of SMC materials, thereby improving the molding quality and production efficiency of products.

Oil Heating

Oil temperature heating, also called heat conduction oil heating. It means that the electric heating tube is placed in the heating oil tank, and the high-temperature heat transfer oil is used to transfer heat to the mold for uniform heating and maintain a certain temperature range. This method is easier to control the temperature, can achieve precise temperature control, and heat evenly, so as to ensure that the mold will not be damaged due to excessive temperature. Heat conduction oil can transfer high-speed heat and heat up quickly, so it is suitable for some bigger and complex shapes molds and molds that require high temperature heating. At the same time, heat conduction oil heating can also maintain the flatness of the mold surface during mold making and processing, avoid problems such as slack and cracks, and make the mold surface deform more uniformly, and it is not easy to appear towering and uneven. However, oil temperature heating also has some disadvantages, for example, the heat transfer oil needs to be replaced frequently during operation, and the heating speed is relatively slow.

For SMC molds, heat conduction oil heating can reduce the internal stress left by shrinkage during processing, make the mold more uniform, and is more effective than electric heating in processing time, which can speed up the production efficiency of the mold, and can also avoid material overheating damage. However, some matters need to be paid attention to during the heating process of heat transfer oil, such as heating on site and safety protection measures.

The above are common heating methods, and the selection of different mold heating methods depends on factors such as mold material, shape and processing requirements.

In modern manufacturing, mold is a key production tool, which is widely used in the manufacturing process of various products. In the production of composite products, Sheet Molding Compound (SMC) mold is a special type of mold. SMC is a high-performance composite material composed of resin, glass fiber and fillers. It has the advantages of light weight, high strength and corrosion resistance. It is widely used in automotive, aerospace, construction and other fields. However, in order to produce high-quality SMC products, die design is a crucial link.

Die design refers to the comprehensive consideration of various factors such as reasonable mold structure, material selection, product design and mold processing in the manufacturing process of SMC molds, so that the mold can be realized in the production process efficient and stable production, and guarantee the quality and performance of the final product. High-quality SMC mold design should have the following characteristics.

Reasonable mold structure

Reasonable mold structure is the basis of high-quality SMC molds. The rationality of the mold structure directly affects the molding quality and production efficiency of SMC products. When designing the mold structure, factors such as the fluidity, shrinkage, and shrinkage rate of the SMC material need to be considered to ensure that the SMC material can fully flow in the mold cavity and fill every detail when the mold is closed. At the same time, the mold structure should take into account the shrinkage and deformation of the product to ensure the dimensional accuracy and shape consistency of the final product. In addition, a reasonable cooling system design is also a part that cannot be ignored in the mold structure, which can effectively control the mold temperature, improve production efficiency and prolong the life of the mold.

Release performance of SMC mold

SMC materials usually require a long curing and hardening process in the mold, therefore, the release performance of the product has a direct impact on the life of the mold and production efficiency. Reasonable product design should include proper demoulding slope, demoulding sequence, demoulding force, etc., so that when the mold is demolded, it can be easily separated from the mold without damaging the product or the mold.

Characteristics of SMC materials

Product design also has an important impact on the quality and performance of SMC molds. Product design should fully take into account the characteristics of SMC materials, including its fluidity, shrinkage, molding difficulty, etc. Reasonable product design can reduce the internal stress and deformation of SMC materials during the molding process, thereby ensuring the dimensional accuracy and appearance quality of the final product. In product design, it is necessary to reasonably set parameters such as product wall thickness, line angle, corner radius, etc., so as to obtain good filling effect and finished product quality during mold molding.

suitable material selection

The mold material should have the characteristics of high strength, high hardness, wear resistance and corrosion resistance, so as to ensure that the mold will not have problems such as deformation, wear and corrosion during the long-term production process. At the same time, the mold material should also have good thermal conductivity in order to better control the mold temperature and improve production efficiency. In terms of material selection, it is necessary to comprehensively consider factors such as the use environment of the mold, production batch, product requirements, etc., and choose a suitable mold Material.

Structural Strength and Stability

SMC products usually need to have high strength and stability to meet their requirements in practical applications. In product design, it is necessary to fully consider the mechanical properties of SMC materials, and reasonably set the wall thickness, ribs, support structures, etc. of the product to ensure the strength and stability of the final product.

Precision and quality of mold processing

High-precision mold processing can ensure the dimensional accuracy and shape consistency of the mold, thereby ensuring the quality of the final product. In mold processing, it is necessary to pay attention to the dimensional control, surface finish, surface coating, etc. of the mold to ensure the appearance quality and performance of the final product. At the same time, high-quality equipment can also improve the precision of the mold.

In conclusion, a good quality SMC mold comes from a good die design. Reasonable mold structure, appropriate material selection, full consideration of product design, and high-precision mold processing are all important factors to ensure the quality and performance of SMC molds.

SMC (Sheet Molding Compound) compression moulding is a manufacturing process used to produce composite materials. It involves compressing a pre-prepared mixture of chopped fibers, typically glass or carbon, and a thermosetting resin, such as polyester or epoxy, between two heated moulds to create a finished part.

The Process of SMC Compression Moulding:

1. Preparing the SMC: Sheet Molding Compound is typically produced by mixing chopped fibers (such as glass or carbon) with a thermosetting resin, along with other additives such as fillers, pigments, and release agents. The mixture is typically in the form of a sheet or a mat.
2. Placing the SMC in the mould: The SMC sheet is placed in the mould, which is usually made of steel and consists of two halves that can be opened and closed. The mould is typically coated with a release agent to prevent the SMC from sticking to the mould during the curing process.
3. Closing the mould: The two halves of the mould are closed, and pressure is applied to compress the SMC sheet. The pressure is typically applied hydraulically and can range from several hundred to several thousand pounds per square inch (psi), depending on the specific material and part requirements.
4. Heating and curing: The closed mould, with the compressed SMC, is heated to a specific temperature, typically in the range of 120 to 180 degrees Celsius (250 to 356 degrees Fahrenheit), depending on the resin used. The heat causes the thermosetting resin to cure and harden, forming a solid composite part.
5. Cooling and demoulding: After the curing process is complete, the mould is cooled, and the pressure is released. The mould is then opened, and the finished SMC part is demoulded. The part may require additional trimming, drilling, or other post-processing operations to achieve the desired final shape and finish.
