(2)混料：将步骤(1)中称取的原料按比例依次顺序加入搅拌桶，充分的搅拌均匀；
(3)抽真空：将步骤(2)中混合均匀的原料装入特定模具，并抽真空，把真空箱调节-0.1Mpa，并维持10-20分钟，确保浆料里空气完全排出；
(4)加温固化：将步骤(3)的浆料和模具一并放入烤箱加热至200-300℃，在此条件下维持3-4个小时，加温结束后进行冷却至常温，维持2-10个小时后取出。
作为改进，所述金属粉末的粒径为100目-800目，包含铜粉、铜合金粉、锡粉、铁粉等任意一种或组合。
作为改进，所述环氧树脂包括缩水甘油醚类环氧树脂、缩水甘油酯类环氧树脂、缩水甘油胺类环氧树脂、线型脂肪族类环氧树脂、脂环族类环氧树脂等任意一种或组合。
