压模及其制造方法
摘要：
本发明涉及一种用于对树脂材料注模成型的压模，其特征在于，在该压模与树脂材料发生接触的表面上形成有一个抗腐蚀膜，该抗腐蚀膜由选自于下述合金材料中的任意一种制成：镍合金、银合金或者铜合金。还有，本发明提供了一种制造压模的方法，包括下述步骤：首先在用于制造压模的模具的表面上形成抗腐蚀膜；然后在抗腐蚀膜上形成所述压模；以及将所述压模和抗腐蚀膜以一体的形式从所述模具上分离下来。由于该压模与树脂材料接触的部分可以抵抗腐蚀，因此，该压模呈现出优良的耐久性。
摘要（英）：

A stamper for use in the injection molding using a resin material, characterized in that it has a corrosion-resistant film comprising one alloy selected from a nickel alloy, a silver alloy and a copper alloy formed on its surface contacting with the resin material; and a method for preparing the stamper which comprises first forming the above corrosion-resistant film on the surface of the mold forpreparing the stamper, then forming said stamper on the film, and releasing said stamper and the corrosion-resistant film in an integrated form from the mold. The stamper exhibits excellent durability, since it has the portion contacting with the resin material which is resistant to corrosion.
