冷間鍛造 精密ネジ製造
Cold Forging / Precision Screw Manufacturing

安定した品質と信頼を第一に
Quality and Trust First

部品は、小さくなるほど要求される精度は高くなります。また工程が増えるほど安定した品質を保つための難易度は高まり、製品における重要度も高まります。坂上鉄工所では、精密ネジのパイオニアとしてこれまで、誠実にお客様のニーズに応え、創意と工夫を重ねることで信頼を築き上げてきました。

The smaller the parts are, the higher the required accuracy becomes. As the number of processes increases, the difficulty of maintaining stable quality increases, as well as the importance of the parts role in products. As a pioneer of precision screws, Sakaue Cold Forging Screws has built trust by responding to our customer needs sincerely, and through repeated creativity and ingenuity.

精密ネジのプロフェッショナルとして
As a Professional of Precision Screws

坂上鉄工所では、精密ネジにおける冷間鍛造後の二次加工を早くから自社に取り入れ、作業効率と品質の安定化を追及して参りました。
品質・技術はもちろん、安定供給力とコストパフォーマンスにおいて他社に追随を許さないレベルを実現しており、国内外のメーカーからも高い評価を得ています。
また、二次加工の強みを活かす二次加工のみの仕事も承っております。

We have been working on the stabilization of work efficiency and quality by incorporating secondary processing after cold forging of precision screws into the company early on.
In addition to quality and technology, we have achieved unrivaled level of stable supply capability and cost performance, and are highly evaluated by domestic as well as foreign manufacturers.
We also accept jobs of only secondary processing, which takes advantage of the strength of secondary processing.
