摘要:
The present invention relates to a resin composition for a mold, a mold constructed by using the composition and a molding method using the mold. This resin composition comprises a thermoplastic resin, an inorganic fibrous reinforcing material and an inorganic particulate filler, and has a bending strength of 1000 kgf/cm² or higher, a modulus of elasticity in bending of 70000 kgf/cm² or higher, and it can be cut and worked. The heat deformation temperature of the composition may be higher than 180 °C. With this composition it is possible to provide a core or a cavity in a mold which is cut and finished with a good dimensional precision, at low cost and in a short period and is durable and recyclable. The mold can be applied to various types of molding methods using various types of materials and when so used it can provide molded products with good precision and at low costs.
