Therefore, the result was casting shrinkage increase accompanied by a decreased flow of the wax pattern. Setting expansion can be obtained sufficiently by softening wax or melting wax. The wax pattern was invested with investment material. After leaving it for 10, 20, 30, and 40 minutes, the mold was kept in a bath at constant temperatures of 55℃ and 65℃ for 60 minutes. This study measured the roughness, compressive strength, setting expansion and heat expansion of investment material, while investigation the relationship between their properties and casting accuracy. The results may be summarized as follows; 1. When the mold was warmed only briefly the setting expansion decreased. There was no significant difference between 55℃ and 65℃. 2. The heat expansion using a non-warmed test piece was larger than with a warmed test piece. 3. The compressive strength of the test piece when warmed to 55℃ was greater obtained stronger than other test pieces. When the test piece was warmed briefly the compressive strength was decreased. 4. The setting expansion was affected by viscosity of wax. 5. When not sufficiently hardened, the setting expansion of the mold obstructed the wax pattern. 6. The thermal expansion due to high softening temperature and high melting temperature of pattern materials affects casting accuracy. But, with a hardned mold pattern materials could not change dimension. 7. The surface roughness increased when the mold was warmed briefly, after the investment was mixed.","subitem_description_type":"Other"}]},"item_20002_description_21":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_20002_full_name_16":{"attribute_name":"公開者(その他言語)","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"松本歯科大学学会"}]}]},"item_20002_identifier_23":{"attribute_name":"資源識別子URI","attribute_value_mlt":[{"subitem_identifier_type":"URI","subitem_identifier_uri":"http://id.nii.ac.jp/1070/00001012/"}]},"item_20002_source_id_25":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0385-1613","subitem_source_identifier_type":"ISSN"}]},"item_20002_source_id_26":{"attribute_name":"処理レコードID(総合目録DB)","attribute_value_mlt":[{"subitem_source_identifier":"AN00232590","subitem_source_identifier_type":"NCID"}]},"item_20002_version_type_51":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"url":{"url":"https://mdu.repo.nii.ac.jp/?action=repository_action_common_download&item_id=1012&item_no=1&attribute_id=22&file_no=1"}}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"鋳造","subitem_subject_scheme":"Other"},{"subitem_subject":"リン酸塩系埋没材","subitem_subject_scheme":"Other"},{"subitem_subject":"Co-Cr合金","subitem_subject_scheme":"Other"},{"subitem_subject":"ワックス","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"鋳型内のワックスの軟化と鋳造精度について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"鋳型内のワックスの軟化と鋳造精度について"}]},"item_type_id":"20002","owner":"3","path":["2412"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-11-10"},"publish_date":"2022-11-10","publish_status":"0","recid":"2157","relation_version_is_last":true,"title":["鋳型内のワックスの軟化と鋳造精度について"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-15T19:03:00.946442+00:00"}
