Title: Manufacture of resin molded product
Inventor: KUMADA MASATAKA
IPC: B29C70/06
Filed: 1985-11-19
Abstract: PURPOSE:To prevent the internal defect and residual stress from developing in a product and enhance the strength of the product by a method wherein a thermosetting resin laminated body, in the respective laminate locating in the inner layer part of which magnetic powder is added and dispersed, is pre- heated by being applied by high-frequency magnetic field. CONSTITUTION:The required amount of magnetic powder is added and uniformly dispersed in thin resin sheets 12. When high-frequency magnetic field is applied to a resin laminated body 10 installed in a high-frequency induction heating device, magnetic metal powder generates heat due to eddy current loss and the resin laminated body 10 is heated in the order of several minutes up to the target temperature for pre-heating. Because a mold is clamped under the state that the resin laminated body 10 which is pre-heated even to the inner layer part is set in said split mold for pressingly heating, the resin laminated body is cured with a small difference between the curing speed in the outer layer part and that in the inner layer part of the resin laminated body. Consequently, high strength molded product with neither internal defect nor residual stress such as outer plate and wheel for automobile is obtained.
