宗基五金有限公司自1988年成立以來，承蒙眾多客戶之支持與厚愛，使我們不斷發展茁壯，在扣環工業製造與內外銷上，達到舉足輕重之地位。我們充分運用幾年來經驗累積，提昇模具之自製量產化，自購CNC日本三菱線切割機，從模具設計繪圖、開模組裝、沖製生產等均採一貫之作業程序，並且針對扣環件原有之缺點加以改良以提高產能，而獲得模具設計之國家專利權。為滿足廣大客戶對品質、價格、交貨與服務之至高要求，我們不斷努力，成為台灣扣環業界首家通過ISO 9002認證之廠商。
為了降低生產成本與超越競爭者，宗基於2009年在台灣購入新廠，並大量添購生產機器、專用機，檢測機器等，以便擴大產能來供應廣大客戶暨長期配合的重要客戶群。
於2011年新廠完工落成後，我們的生產能力比以往提升50%，且為了掌控關鍵製程以因應車廠客戶之需求，於2013年採購鹽浴式調質熱處理設備及 X-RAY膜厚測驗機
，在廠內自行進行熱處理製程及檢測,使我們更能有效掌控品質及產能；而以沃氏回火方式即鹽浴式調質熱處理之產品，亦是韌性最佳之扣件。
再加上本公司為了提升交貨速度，並於同年起陸續購入了自動化專用機和自動化篩選機。且在2013年，為了使我們長期客戶及車廠客戶端更加信任本公司之產品品質與製造能力，進行推動ISO/TS 16949品質系統並於2015年通過合格認證。今年，2016年，本公司購入數台自動化光學檢測機(CCD)，再次推升產品品質達到更高層次。
Since the establishment of Tzong Ji Metal Co. in 1988, in gratitude to all our customers for their cordial patronage and support we continuously grow up in both oversea and domestic industrial fasteners markets, and finally play a pivotal role in the field of retaining rings and clips. With the help of self-owned MITSUBISHI wire cutting machine, we adopt a thoroughly integrated process including tooling design, cutting steel plates, tooling assembly, and stamping manufacturing; and in view of promoting the production we modified the original tooling design for retaining rings to reduce the drawbacks in manufacturing process. National patents for new designs of molds for producing retaining rings and wave washers were also approved in the past years. After incessant struggles for achievement of high quality products and content service standards, we became the first company in this field to acquire ISO 9002 certification in Taiwan. Therefore, in order to further reduce cost and surpass our competitors, Tzong Ji Metals invested a new factory in 2009 in Taiwan and purchased a large number of production machines like special purpose machines and testing machines...etc., so as to expand production capacity to supply all customers and especially the valued long-term customers. In 2011, our new factory was completed and our production capacity was increased by 50%. In expectation of controlling the critical production process to meet the demands from our automobile manufacturing customers, in 2013 we purchased a salt bath heat treatment furnace (Austempering) and a X-ray instrument for coating thickness measurement. With these in-house equipments we can get better control of the quality and the yield. It is well known that austempered fasteners show excellent performance on strength and wear resistance. In the same year we also purchased several automated machines and automated sorting machines so as to expedite the delivery schedule. In 2013, for getting further trust from customers we started to implement ISO/TS 16949 quality management system and got the certificate in 2015. In 2016, after we purchased several automated optical inspection machines (CCD), our product quality is boosted to a higher level now.
