GMT is a glass mat-reinforced thermoplastic. GMT fiber composite has high flow properties, which enables the production of thin-walled automotive components to achieve low-cost features. The impact resistance, mechanical strength and hardness of these components have been improved.
Compared with general engineering plastics, GMT material has lighter weight and more ideal performance. Compared with other composite materials, such as thermosetting SMC (sheet molding compound), it also has a short molding cycle, good impact performance, and recyclability. Outstanding advantages such as utilization and long storage period. Based on this, the automotive industry has also begun to devote itself to the development of environmentally friendly GMT composite materials in recent years.
The advantages of GMT materials: recycling, low-pressure molding, long storage period, short molding cycle, and high production efficiency.
GMT material application field: mainly used in the automobile and construction industry, including chemical industry, packaging, sports equipment and so on.
DEYING Mould is a GMT mould supplier, engaged in the design and manufacture of composite GMT moulds. It has been developing GMT moulds for Mercedes-Benz C series, E series, AMG and other models. For example, the GMT bottom guard plate composite mold developed by MDC for the Mercedes-Benz E300 model.
What are the characteristics of GMT molding process?
1. Compared with sheet metal, GMT is light in weight, with a density of about 1/6~1/7 that of steel; it is corrosion resistant and does not rust; it has good heat insulation, sound insulation and insulation properties; it can be processed into complex products at one time.
2. Compared with sheet molding compound (SMC), GMT has an extremely long storage period; the product molding cycle is short, which is 3/1 to 1/4 of SMC; it can be recycled and used without pollution; it has good impact toughness. Compared with short fiber, it has high strength and good rigidity; good creep resistance and long service life; good heat insulation, sound insulation and insulation performance; good product dimensional stability.
GMT mold is a cavity tool with a certain shape and size. It is used in conjunction with various systems or auxiliary mechanisms in the mold to fill various high-temperature liquid GMT materials into the mold cavity to produce a specific shape , Size, function and quality of GMT parts.
