Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 金属(又は非金属、又はこれらの化合物) と、合成樹脂と、からなる多材質成形品を安価に成形で きるようにする。 【構成】 キャビティ容積が最終的な容積よりも小さい 状態でキャビティ内に金属などの第1溶融材料を射出 し、次にキャビティ容積を最終的な容積とした状態で第 1材料部以外のキャビティ空間部に溶融樹脂を射出す る。金属(又は非金属)としては、亜鉛、すず、鉛、ビ スマス、テルビウム、テルル、カドリニウム、タリウ ム、アスタチン、ポロニウム、セレン、リチウム、イン ジウム、ヨウ素、いおう、ナトリウム、カリウム、リ ン、ルビジウム、セシウム、フランシウム、及びガリウ ムが選択されるが、これらの化合物で融点450℃以下 のものを用いることもできる。 (57) [Summary] [Purpose] Metals (or non-metals or their compounds) And a synthetic resin, so that a multi-material molded product can be molded at low cost. [Structure] A first molten material such as metal is injected into the cavity in a state where the cavity volume is smaller than the final volume, and then the cavity space other than the first material portion in the state where the cavity volume is the final volume. Molten resin is injected into the part. Examples of the metal (or nonmetal) are zinc, tin, lead, bismuth, terbium, tellurium, cadolinium, thallium, astatine, polonium, selenium, lithium, indium, iodine, sulfur, sodium, potassium, phosphorus, rubidium, cesium, francium. , And gallium are selected, but compounds having a melting point of 450 ° C. or less can also be used.
