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 high thermal stability is suitable for the aerospace industry, the automotive industry and the composite material manufacturing industry, which have high requirements on material properties. Moreover, it also fills the gap in the company's production of high-tolerance parts, and also solves the difficulty of finding out A problem with 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 replacement for metal tools. In addition, FR-4800 has a density of only one-third of aluminum and 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 of parts. With the use of large graphite molds Increasing quantities, material complexity and size, the ability to accurately create surfaces and speed 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.
FR-4800 is similar to other high temperature mold foams manufactured by General Plastics, LAST-A-FOAM® FR-4700, but FR-4800 has advantages not found in other materials. FR-4800 has a coefficient of thermal expansion (CTE) ) Lower, high processing temperature and high thermal conductivity, can provide customers with a mold board with good thermal properties.
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, with continuous cooling rates, no distortion and predictable dimensions. This product range includes fiber reinforced composites. Materials, high temperature resin systems, prepreg composite lamination tools, foam body materials, bulk tools and molds, and prototype tools. Commercial high temperature adhesives and sealants, usually used with composite or polyurethane tool boards, Used with the FR-4800.
