長春成門電子有限公司，是韓國成門電子株式會社下屬的一個分公司，并且經營的一個獨資公司；公司成立于2000年1月，位于吉林省長春市高新技術產業開發區內；公司的主導產品為電容器用鋅鋁復合金屬化薄膜。公司目前在冊員工為60名，其中大學專科以上學歷的職員15名，本科以上學歷的職員6名，公司員工基本上都是高中以上學歷。
公司的主導產品，電容器用鋅鋁復合金屬化薄膜廣泛地應用于金屬化薄膜電容器的生產制造當中，具有非常廣闊的市場和應用前景，該產品是二十世紀九十年代初期開發研制出來的新產品，是以前所使用的單鋅金屬化薄膜和單鋁金屬化薄膜的更新換代產品，所以其技術含量較高，其本身的技術水平也是較為先進的，特別是在韓國成門株式會社租賃后，對公司的生產技術又進行了改進和改造，對蒸發設備的蒸發系統進行了更新，利用二十一世紀才出現的世界上先進的技術，采用α-線進行蒸發，使產品的性能更加和完善，在同行業中處于的地位。公司的主導產品鋅鋁復合金屬化薄膜早在1998年4月份就已經通過了ISO 9002質量體系認證。同時該產品也曾屢次榮獲過各種各樣的獎勵，主要有1994年榮獲第二屆中國長春電影節《科技成果暨高新技術展覽會》成果二等獎，1994年度國家級新產品獎、1995年“講理想，比貢獻”項目一等獎等。
目前，公司的設備主要有：蒸發設備二臺、分切設備五臺、真空包裝設備二臺，主要設備都是從國外引進，其中蒸發設備一臺是1991年由國營第七九三廠從當時的西德購買，另一臺是2002年10月份從韓國引進的；分切設備當中，兩臺是公司成立時從韓國引進，另三臺是2002年10月從韓國進口。
公司的主要產品有兩大類：電容器用鋅鋁復合金屬化聚丙烯薄膜和電容器用鋅鋁復合金屬化聚酯薄膜，均為金屬化薄膜電容器生產所使用的主要材料，其中電容器用鋅鋁復合金屬化聚丙烯薄膜的生產范圍為4-12微米，電容器用鋅鋁復合金屬化聚酯薄膜的產生范圍為3-16微米，目前的生產能力為年產700~800噸。
