LOW-TEMPERATURE COATING METHOD FOR RESIN MASTER PATTERN AND INJECTION MOLD MAKING METHOD THEREOF

摘要

The present invention relates to a low temperature coating method for a resin master pattern and an injection mold making method using the low temperature coating method. The injection mold making method using the low temperature coating method for a resin master pattern comprises: a step of making a resin master pattern; a step of forming a ZnO thin film on a surface of the resin master pattern in a low temperature atmosphere; a step of making a resin mold by using the resin master pattern on which the ZnO thin film is formed; a step of hardening the resin mold; and a step of removing the resin master pattern from the resin mold. The injection mold making method using the low temperature coating method according to the present invention has an effect of making a mold which precisely expresses the intaglio of the resin master pattern by easily separating the resin master pattern from the mold, and prevents the mutual diffusion bonding of the resin master and the mold by evenly coating the ZnO thin film on the surface of the resin master pattern by using atomic layer deposition in a low temperature atmosphere,.
