SMC (Sheet Molding Compound) is a high-strength, lightweight composite material composed of resin, glass fiber, and fillers. SMC molds are commonly used to manufacture various types of complex shaped parts, such as automotive shells, aircraft components, ship parts, and so on. Therefore, in the manufacturing process of SMC molds, machining accuracy is a very important aspect.

As a professional SMC mold manufacturer, MDC Mould is equipped with experienced engineers, imported equipment, and sophisticated processing processes that can meet customer quality requirements. Today we will introduce the Spark Erosion Machine used in MDC Mould.

Spark Erosion Machine, also known as electrical discharge machining machines, is a method of cutting workpieces through electrical discharge. In this process, the gap between the electrode and the workpiece is filled with a liquid medium (usually deionized water), which can generate electrical discharge between the electrode and the workpiece, and can also wash away the debris of the material being cut.

The main working principle of a spark erosion machine is to generate electrical pulses on the surface of the workpiece to discharge electricity, which ionizes the medium between the electrode and the workpiece, thereby generating a series of electric spark discharge phenomena. Each electric spark discharge process will impact and detach small particles on the surface of the workpiece, and the electrode will gradually consume. Through repeated electric spark discharge processes, small particles on the surface of the workpiece are gradually worn and reduced, ultimately forming the desired shape and profile.

Advantages: The spark erosion machine has high machining accuracy and can accurately process complex shapes and contours in SMC molds. That is to say, the obtained SMC mold not only has high accuracy, but also has high surface quality. At the same time, the processing process of a wire cutting machine does not generate thermal deformation or cutting stress, so it does not adversely affect the performance of SMC materials. This makes spark erosion machine one of the ideal choices for manufacturing SMC molds.

In short, as a well-known compression mold manufacturer at home and abroad, if you have any needs, then MDC Mould will be your best choice.

The design and manufacturing quality of the mold directly affects the quality and performance of the final product. For example, in aircraft manufacturing, it is necessary to manufacture a large number of products with complex shapes, so SMC molds with high precision, high stability and high efficiency are required. Only in this way can the needs of aircraft manufacturing be met, and the quality and safety of products can be guaranteed.

MDC Mould is a professional mold manufacturer, famous for its excellent technology and high-quality products. The company has a skilled and experienced R&D team, as well as a group of high-quality production workers, committed to providing customers with the best quality mold solutions. Whether you need mold design, manufacturing, or processing to after-sales service, MDC Mould always takes customer satisfaction as the highest goal, adhering to the corporate philosophy of “quality first, integrity first“, constantly pursuing excellence and innovation, and winning the trust of customers and praise.

During the production of SMC molds, it is unavoidable to generate pollutants such as waste water and waste gas. The threat to the environment and human health caused by the discharge of these waste materials cannot be ignored. Therefore, it is necessary to carry out environmental protection technologies such as waste water treatment, waste gas treatment and resource recovery.

waste water treatment

Waste water treatment refers to a technology that removes or transforms harmful substances in waste water to meet discharge standards. During the production of SMC molds, the waste water mainly contains harmful substances such as resins, solid particles, chemicals, and oils. We have three ways. Physical treatment mainly uses filtration, precipitation, membrane separation and other methods to remove solid particles and grease in wastewater; chemical treatment mainly uses oxidation, reduction, precipitation and other methods to chemically transform harmful substances in wastewater; biological treatment mainly uses microorganisms to degrade and transform harmful substances in waste water. After it, the harmful substances in the wastewater are removed or transformed to meet the discharge standards required by environmental protection, which can reduce environmental pollution.

waste gas treatment

Exhaust gas treatment refers to a technology that removes or transforms harmful substances in exhaust gas to meet emission standards. During the production of SMC molds, the exhaust gas mainly contains harmful substances such as volatile organic compounds and nitrogen oxides. The methods of exhaust gas treatment also mainly include physical, chemical and biological treatment.

resource recovery

In addition to processing, we can also recycle useful substances in waste materials. In the production process of SMC molds, resins and solid particles in waste water can be recovered by precipitation, filtration and other methods; volatile organic compounds in waste gas can be recycled by pyrolysis and other methods, and resources such as heavy metals in waste water and waste gas can also be recovered. It can be recycled by physical and chemical treatment and other methods.

For SMC mold manufacturers, it is necessary to establish waste water treatment systems, waste gas treatment systems and resource recovery systems to promote the sustainable development of the mold industry.

In the process of continuous research and development of higher-quality, higher-tech molded SMC molds, MDC Mould also pays attention to environmental protection and contributes to sustainable development.

MDC’s vacuum forming technology is a technology in which the mold is extracted from the air in the process of pressing the air, and the mold is usually produced and manufactured. MDC mold also adopts vacuum forming technology, which has a long service life, light weight and high strength, and is not easy to corrode.

Principle of vacuum forming mold:

Vacuum forming is to fix the thermoplastic sheet and sheet on the mold, heat it with a radiant heater to reach the softening temperature, and then use a vacuum pump to remove the air between the mold and the plate (sheet), so that the plate (sheet) The material parison is formed according to the contour of the mold. With the increase of the vacuum degree, the forming pressure under the parison is only 0.06-0.085MPa, while the air pressure above the parison remains at about 0.1 MPa. After cooling and setting, the product is blown out of the mold with compressed air and demolded.

Vacuum forming mold forming method:

Vacuum forming methods mainly include concave mold vacuum forming, punch vacuum forming, concave and convex mold vacuum forming successively, bubble blowing vacuum forming, auxiliary punch vacuum forming and vacuum forming with gas buffer device.

Advantages of vacuum forming molds:

(1) Saving raw and auxiliary materials, light weight, convenient transportation, good sealing performance, and meeting the requirements of environmental protection and green packaging;

(2) It can pack any special-shaped products without additional buffer materials;

(3) The packaged products are transparent and visible, beautiful in appearance, and easy to sell;

(4) The packaged products are suitable for mechanized and automated packaging, which facilitates modern management, saves manpower and improves efficiency.

MDC has been using vacuum forming technology, focusing on composite molds and molding molds, is a very professional SMC mold manufacturer, mainly engaged in SMC molds, BMC molds, GMT molds, LFT molds, etc., glass fiber reinforced plastic molds and carbon fiber molds These hot pressing molds The design, development and manufacture of the company’s molds are deeply trusted by customers.

Last Month, MDC Mould had an exhibition overseas. As a professonal compression mould maker in china, we always looked for an opportunity to expand our markets, that’s the reason why MDC mould can keep growing year by year.

In regards this composite exihibition, too many experts who have experienced in composite industry were coming to see new composite products including Automotive, Aerospace, construction industries. MDC Mould has worked such projects covered above industries with their european customers especially IMP on SMC and GMT Mould, as well as IMC on SMC mould.

Herewith I attached a video that MDC team were attending in a meeting who reported new composite material development and application in different industries.

Please keep in touch with us, when any doubts on SMC Mould.
