MDC wants to tell suppliers why we choose to make SMC molds through this article.

Regarding the origin of the name MDC, MDC means the foothold of manufacture, development and creation.This is also the purpose of our manufacturing mold practice.

Let’s first understand the manufacturing process of SMC mold.

Moulding of SMC mould Parts:

Moulding is made in heated steel tools at temperatures between 125°C and 170°C. It is very important to take note of the setup instructions of each specific material due to the variety of formulations. All known processes are possible as the material will be tailor made for your specific process and application.

Compression moulding cycle

Layers of SMC are placed into the heated tool. Through closing the tool the material fills the cavity and polymerizes. After complete cure the parts are released hot. With compression moulding highest mechanical strengths can be achieved.

Applications

Market penetration for SMC mould is gaining ground in terms of both end-use applications and global demand. Suppliers are reporting more interest in SMC from industrial, consumer, building and construction, energy generation, electrical / electronic, non-automotive transportation, and even aerospace customers.

Increasing performance demands in automotive, electrical, appliance, food service, and energy industries, among others, plus the rising cost of cast metals, is prompting design engineers to consider metals conversion to alternate materials for new products. Thermoset composites have many unique properties – exceptional strength, light weight, corrosion resistance, UV resistance, electrical non-conductance, exceptional thermal properties – that make them desirable over thermoplastics and, in particular, metals, such as cast steel and aluminum.

For instance, thermoset composite materials can be used outdoors and in extreme environments, as they will not rust or corrode. And, because many components can be molded along with the part, and require no final finishing, they are often more economical from a total manufacturing standpoint.

MDC has excellent designers, perfect equipment and strict testing links, we will make customers feel the greatest sincerity.

Please believe that MDC has many years of experience in SMC mold design and manufacturing, which can meet your needs.

SMC is a flat sheet-like compound, produced on a continuous moving belt process. The SMC composites are made from chopped multi end rowing strand sandwiched between two layers of film, onto the resin paste (resin, shrink compensation, fillers, additives and curing agent) has already been applied. The prepreg passes through a compaction system that ensures complete strand impregnation and makes a sheet wound into rolls. These are stored for pre maturing before moulding to allow the prepreg to thicken into a mouldable viscosity.

A typical formulation for a SMC is given below.

Raw material	Parts by weight
Unsaturated Polyester resin	60
Low profile additive	40
Peroxide	1.5
Fillers	150
Release agent	4
Magnesium oxide paste (35% MgO)	2
Glass fibres	25%on total formulation

SMC is a moulding compound made on the basis of glass-fibre reinforced unsaturated polyester resin. The use of Sheet Moulding Compound (SMC) is a very important production process for high volume production.

Bayer AG in Germany was the first to develop a process to produce thermoset polyester sheet molding compound (SMC) during the early 1960s, while Owens Corning Fiberglas was instrumental in bringing the process to the U.S. SMC combined resin, filler, and chopped glass in a doughy, easily handled sheet. The emergence of SMC resulted in the first mass-production process for composites, which offered a wide range of advantages over open-mold hand lay-up and spray-up composite methods.

As the most advanced and popular equipment shell manufacturing material in the world, SMC composite material has incomparable advantages over other non-metallic materials and metal materials.

Composite materials and metals, polymers, and ceramics are called the four major materials.

SMC material itself has good anti-aging properties. SMC is currently the mainstream material on the market. SMC composite materials can effectively resist the corrosion of seawater, gasoline, alcohol, electrolytic salts, acetic acid, hydrochloric acid, sodium-potassium compounds, urine, asphalt, various acid-alkaline soils and acid rain.

Among non-metallic materials, fiber-reinforced polyester materials have excellent anti-aging properties. Anti-aging performance tests show that the maximum degree of surface aging is small in different locations and climatic zones, so there is no significant effect on the mechanical properties of the product.

SMC material has good impact toughness. Therefore, it is suitable for the entire bathroom, the entire bathroom overhead structure layer, and an air layer is formed between the waterproof chassis and the ground, which can effectively buffer the impact. At the same time, with thermal insulation properties, the skin feels warm and insulated in winter and summer.

SMC material has high plasticity. SMC can be used in a variety of applications according to the design requirements of structural design and surface texture design (leather texture, wood, stone, sand surface, smooth surface and other surface textures), common applications are leather textures, such as aircraft warehouse boards, mobile Auto warehouse interior panels and auto warehouse panels mainly choose texture, which is not only durable or durable, but with the continuous application of new technologies, the surface’s anti-scratch, anti-static, and easy-to-clean properties are greatly improved.

Products made of SMC materials are green and environmentally friendly. SMC is lightweight, durable and has a long (50) year lifespan. At the same time, the formaldehyde emission standard of SMC material reaches E0 standard level, contains no halogen, and has no harmful substances to the human body.

So, how is SMC material made into SMC mould?

The SMC molding process is to put the sheet plastic into a mould that has been heated to a specified temperature, pressurized by a hydraulic press, so that the molten sheet plastic evenly fills the mold cavity, and then after a period of pressure-holding heating and curing, it becomes an SMC mould.   SMC has the advantages of superior electrical properties, corrosion resistance, light weight, easy engineering design, good flexibility, etc. Its mechanical properties can be comparable to some metal materials, so it is widely used in transportation, construction, electronics/electrical, medical, bathroom, etc. industry.

The material of automobile bumper has undergone a change from metal to plastic. Early front and rear bumpers are mainly metal materials, riveted or welded together with the frame rail, and there is a large gap with the body, the quality is large, the appearance and body style is difficult to unify.

With the development of automobile industry, engineering plastics have been widely used in automobile manufacturing due to their characteristics of light weight, corrosion resistance and large design freedom. At present, the front bumper of the car on the market is generally made of polyester (such as PBT) and polypropylene (such as PP), which are made by injection molding.

The existing front bumper adopts integrated injection molding, which has the advantage of efficient and mass production, but has the following disadvantages:

First, due to the large size of the parts themselves, the more complex the front bumper modeling parts design, manufacturing is more difficult, higher requirements for the mold;

Second, the current bumper surface in any area of irreversible collision defects, can only be replaced by the whole part;

Third, at present, there are mainly several kinds of plastic front bumper appearance color design: keep consistent with the body, through spray paint color separation design, but also maintain the original color appearance of injection parts without spray paint.

With the improvement of the user’s requirements for car selection and the improvement of the quality and appearance requirements of the oEMS, the manufacturing of automobile bumper is constantly improving from both material and design. Using SMC molding process, SMC bumper mold can more meet the needs of people now on the car. The main reasons are as follows:

First, compared with the traditional integral plastic front bumper post maintenance and replacement, SMC bumper mold is more convenient and low maintenance cost.

Second, SMC bumper mold high temperature resistance, oil resistance, corrosion resistance.

Third, SMC bumper mold strength is stronger, can achieve safe performance.

Fourth, low cost, small weight. Not only that, SMC bumper mold can also in peacetime slight collision, rebound back to the original state, greatly reducing the cost of maintenance.
