    • A mold for uniform heating and molding of work material to form a workpiece of variable thickness using a microwave oven includes upper and lower mold members and a sidewall mold member. Metal inserts, with irregular inner surfaces defining a mold cavity, are positioned adjacent opposed planar surfaces of the upper and lower mold members. The mold members are formed from material selected to have an effective thermosensitivity equal to that of the work material. The effective thermosensitivity of work material is its dissipation factor divided by the product of its dielectric constant, density and specific heat multiplied by the fraction of the mass of work material divided by the total mass of work material and metal inserts. The effective thermosensitivity of the material of inner layer of mold member is its dissipation factor divided by the product of its dielectric constant, density, and specific heat and multiplied by the fraction of the mass of its inner mold layer divided by the total mass of this mold member.
    • 使用微波炉对工件进行均匀加热和模制以形成可变厚度的工件的模具包括上下模具构件和侧壁模具构件。 具有限定模具腔的不规则内表面的金属插入件位于上模具构件和下模具构件的相对的平面表面附近。 模具构件由选择为具有与工件材料相当的有效热敏性的材料形成。 工作材料的有效热敏性是其耗散因子除以其介电常数,密度和比热乘以工件材料质量除以工件材料和金属插件总质量的乘积的乘积。 模具内层材料的有效热敏性是其耗散因子除以其介电常数,密度和比热的乘积乘以其内模层质量的分数除以其总质量 模具成员。
