General Plastics Manufacturing Co., Ltd. is a global supplier of high performance polyurethane foam products and composite parts. The company recently announced that it will introduce a high temperature mold foam board of the type LAST-A-FOAM® FR-4800 series. This foam board is a A tool plate with relatively high thermal stability, suitable for aerospace industry, automotive industry and composite materials manufacturing industry with high requirements on material properties. Moreover, it fills the gap in the company's production of high-tolerance parts, and it also solves the problem of finding a tool system that is both cost-effective and predictable in size and stability.
LAST-A-FOAM® FR-4800 series plates are ideal for peak temperatures up to 480°F (249°C) and continuous use temperatures up to 400°F (204°C) due to their thermal expansion coefficient and aluminum Quite, so it is also an ideal substitute for metal tools. In addition, the FR-4800 is only one-third the density of aluminum and has a density of 48 pounds per cubic foot (0.77g/cm3).
' FR-4800 high temperature mold plate 'FR-4800 mold plate has the advantages of high temperature resistance, low thermal expansion coefficient, etc. It is also an alternative material for prototyping, proof of concept and short-term production parts. With the increasing use of large graphite molds, the complexity and size of materials, the ability and speed to accurately generate surfaces becomes more challenging.
Mitchell Johnson Ph.D., CEO/President of General Plastics, said: 'FR-4800 foam board is the latest generation of materials, very suitable for use as the main material for carbon fiber tools or foam tools. It can be easily and quickly The material is machined to very complex shapes and, compared to other mold methods, it can produce the desired foam body material in a shorter period of time and at a lower total cost.
The FR-4800 is similar to other high temperature mold foams manufactured by General Plastics, LAST-A-FOAM® FR-4700, but the FR-4800 also has advantages that other materials do not have. FR-4800 can provide customers with a mold plate with good thermal properties due to its lower coefficient of thermal expansion (CTE), high processing temperature and high thermal conductivity.
Mitchell Johnson Ph.D also said: 'We introduced the LAST-A-FOAM® FR-4800 series to produce a predictable and reliable mold foam board, and this material is suitable for those dimensional stability against high pressure steaming In addition, the coefficient of thermal expansion of this material is reliable and repeatable. Researchers can calculate the correction factor of the tool while improving the ability to produce more accurate material surfaces.
LAST-A-FOAM® FR-4800 can be easily machined, even at continuous high temperatures, it has a continuous cooling rate, no distortion and predictable dimensions. Applications include fiber reinforced composites, high temperature resin systems, prepreg composite lamination tools, foam body materials, bulk tools and molds, and prototyping tools. Commercial high temperature adhesives and sealants, usually with composite panels or Polyurethane tool board for use together with FR-4800.
