An English description is being prepared. Japanese description:
鋳物は、仏像や梵鐘などをはじめ、鍋や釜など日常生活用具をつくる技法として発達してきた。現代の鋳物製品は、これらの日用品だけでなく、各種の工作機械をはじめ、発動機、車両、船舶、航空機、電気機器、農機具などの部品として、さまざまな分野で幅広く使用されている。鋳物には鉄鋳物や銅合金鋳物、アルミニウム合金鋳物など各種の材質のものがある。
鋳物製造の代表的な製造方法としては、砂型鋳造と、金型を使うダイカスト鋳造がある。ここでは砂型鋳造について記載する。まず、砂に樹脂や硬化剤を混ぜて鋳物砂を作る（混砂）。次に、鋳物の中空部を作るために、鋳型にはめこむ砂型（中子・なかご）を作り、鋳型枠に製品の模型である木型や金属型を置き、まわりに鋳物砂を詰めて主型（おもがた）を作り、中子をはめこんで上型と下型を合わせると、鋳型が完成する（造型）。
次に、銑鉄など鋳物の原料を配合し、溶解炉で熱して溶かす（溶解）。予定の成分調節を行い、適当な温度に溶かした金属を鋳型の中に注湯口から流し込む（注湯）。冷めたら鋳型をばらして、鋳物を取り出し、砂などを落として仕上げる（仕上）。
また、生産の自動化が進んでいる職場では、ダイカスト製品を製造するための生産設備を運転・操作して鋳型に溶融金属を注入する工程などを鋳造設備オペレーターとして監視・調整する。

Projected pay for 鋳造工/鋳造設備オペレーター (3, 5 and 10 years)est.
Today ¥5.07M → in 3 years ¥5.46M → in 5 years ¥5.73M → in 10 years ¥6.48M (10-year range ¥5.57M–¥7.52M). The model assumes pay growth of +2.5% per year.
What drives the annual growth rate
Projected pay = current pay × (1 + annual growth)^years. The annual growth rate starts from a base wage-growth rate and adds or subtracts labor demand (the job-openings-to-applicants ratio), wage momentum and AI replacement risk for each occupation. Projections are not guarantees. How it is calculated →
Outlook score for 鋳造工/鋳造設備オペレーター
Each component is a percentile rank among all occupations in the same country (0–100). Weights: labor demand 25, wage momentum / openings 15, pay level 15, AI resistance 25, aging workforce 10 (Japan only), entry barrier 10.
Will AI replace 鋳造工/鋳造設備オペレーター? AI replacement risk
How AI is changing this job
A written analysis for this occupation is being prepared.
AI replacement risk compares the parts of a job that are easy to hand to AI or software (processing information, documentation, repetitive computer work) with the parts that are hard to automate (physical work, working closely with people, judgment in unpredictable settings), using the MHLW job tag survey on work activities, work context, skills and knowledge. The result is a relative position among all occupations in the country, scaled to 0–100%. Methodology →
Labor demand for 鋳造工/鋳造設備オペレーター
A ratio above 1.0 means there are more job openings than applicants (a labor shortage). The 5- and 10-year figures are estimates from the openings ratio, wage momentum and AI replacement risk.
