    • PURPOSE: A solution for the manufacture of a cold mold capable of manufacturing a plurality of mold test pieces within a short time at low temperature and a molding method using the same are provided. The molding method can reduce the decision time of metallographic examination and the cost of production. CONSTITUTION: The solution comprises 230 to 270 parts by weight of an unsaturated ester resin solution, 0.4 to 0.6 parts by weight of paraffin, and 0.8 to 1.2 parts by weight of a hardening agent comprising 55% by weight of methyl-ethyl-ketone peroxide and 45% by weight of DOP or DVP as a stabilizer. The molding method using the solution comprises the steps of: preparing a mold by pouring the solution into the inside of a mold hold and heating at 60 to 70deg.C; and separating the mold from the mold hold.
    • 目的:提供一种能够在短时间内在低温下制造多个模具试样的冷模具的制造方法和使用该模具的成型方法。 成型方法可以减少金相检查的决策时间和生产成本。 构成:该溶液包含230至270重量份的不饱和酯树脂溶液,0.4至0.6重量份的石蜡和0.8至1.2重量份的硬化剂,其包含55重量%的甲基 - 乙基 - 酮过氧化物 和45重量%的DOP或DVP作为稳定剂。 使用该溶液的成型方法包括以下步骤:通过将溶液倒入模具内部并在60至70℃加热来制备模具; 并将模具与模具夹持件分离。
