It is a continuous glass fiber felt, it is a continuous glass fiber mat, chopped glass fiber felt, cloth, roving and thermoplastic resin composite of a sheet mold plastic. Sheet molding compound.

13.1.1 13.1.1 overview

Thermoplastic sheet molding processing products - sheet stamping forming process of preheating material preheating; stamping; thermoplastic sheet molding processing products and process sheet stamping die preheating thermosetting sheet of plastic processing products - hot forming process. Hot pressing. Thermosetting plastic sheet molding processing products and process of hot press molding thermoplastic sheet molding plastic products and product characteristics: thermosetting

thermoplastic sheet molding plastic products and thermosetting products characteristics: 1) is 1 higher than the ratio of strength to strength) plastic sheet molding high strength and the hand glass steel is similar to that of table 1313 thermoplastic of SMC strength and GRP similar, see table 13-2 density density (1.1 ~ (1.1 ~ 1.6 g/cm3) strength thermosetting products are shown in table 1313 and thermoplastic, 1.6 ~ 1.6 density strength thermosetting products are shown in table 13-2, when compared with thermoplastic, density of 1.6 ~ 2 g/cm3

2) can repeat processing molding 2) can repeat processing, forming, corner, waste materials, waste, etc. can be repeated processing, save materials, reduce costs. Edges, leftover materials and waste materials can be repeatedly processed to save materials and reduce costs. 3) 3) short molding cycle short molding cycle SMC thermosetting molding cycle 6 SMC molding cycle SMC thermosetting molding cycle 6 ~ 15min SMC thermoplastic molding cycle 20 SMC molding cycle 20 ~ thermoplastic molding cycle SMC 20 ~ 60s high production efficiency, easy to realize automation and mechanization of production. High production efficiency, easy to realize automation, mechanization production. 4) 4) low pressure molding molding pressure low plastic sheet molding stamping pressure 3 ~ 8MPa thermosetting sheet molding plastic molding pressure of 3 ~ 5 15MPa) long storage period 5) long storage period of thermoplastic sheet molding can be stored for more than a few years; thermoplastic sheet molding can be stored for
