We are confident in quality, cost, and delivery! We provide integrated services from cutting, grinding, heat treatment, and surface treatment.

Lead pin manufacturing for electronic components We specialize in ultra-fine processing press dies and construction of wire and thin sheet materials.

We supply a large number of die-cast products to customers in a variety of industries, including electrical, electronics, automotive, and telecommunications. 

We manufacture ultra-fine pipes of various cross-sectional shapes using fine ceramics based on our PILOT mechanical pencil lead manufacturing technology.

Our stock of materials, which is superior to that of material trading companies, enables us to provide a wide variety of resin-processed products in small quantities at high quality and low cost.

We support a variety of prototypes, including small and large products, complex shapes, and sand mold castings with high technical difficulty, such as thin-walled shapes.

New deep engravability is realized with free-cutting performance in the μ range and thickening in the mm range.

We have a wide delivery record, mainly for automotive parts, but also for home appliances, lighting equipment, and general machinery parts.

We introduce a technology that can simultaneously impart the contradictory properties of anodized aluminum (insulation) and silver plating (conductivity).

Citizen's unique surface hardening treatment technology prevents the hardened layer from peeling off and provides scratch resistance.

Leave the plating of bus bars, terminals, electrical and electronic parts to us.

Our plating technology has excellent sliding durability even in dry environments, and can provide high sliding performance to rubber materials.
