Product Details

Specifications

Can get functional properties that the single metal doesn't have by adding functions to base metals.

Pre-coated steel Coated the surface of the metal with a functional resin ,endows insulation, reduced friction

Features(Overview)

We can add special properties to metals which cannot be obtained

with simple metals, such as listed below.

By combining our company's unique component technologies,

we can help your company achieve a reduction in total costs

and an improvement in product quality.
Because our products are custom-made, we make each products

with exact specifications to satisfy your requests.

Additional features

•Clad metal:

Bonding two or more different types of metals together allow

to the metal includes all the properties of them.

•Functional pre-coated metal:

Coating the surface of the metal with a functional resin coat adds it properties

that the original metal does not possess,

such as insulation, low-friction, corrosion resistance, and coloring.

•Molten solder plating metal:

A metal plated with a thin layer of melted solder.

Because of the diffusion bonding structure at the interface between two materials,

there is no worry of exfoliation(separation) or whiskers as there is with tin electroplating.

Very suitable for hard bending or pressing.

•Multigage metal:

Make the metal thickness uneven by skiving.

The machine-skiving processing enables very precise thickness

and small production quantities.

Main uses

Resistor components, thermal protectors, printer springs, connector shells,

keyboard springs, shield cases, surge absorbers, relays, power window contacts,

other connectors and contacts, battery cell components, membrane switches,

fire alarm contact lead frames, car horns, clock needles, etc.

Manufacture process

Manufacturing Processes	Outline
Base metal	We carefully balance quality, delivery time and price, procure various base matals from all over the world. We manufacture appropriate products to your needs.
Cold rolling	We have rolling machines like 18-high mills (Z-High type), 24-high mills (Sendzimir type), and 4-high mills, etc. We choose suitable rolling machine for each specification of metals. An AGC program in rolling machines controls pressure and position, enables an accuracy of ±1~3μm at thicknesses 0.20 mm or less, and ±1% at thickness greater than 0.30 mm in cold rolling process.
Annealing	We possess BA (Bright Annealing; Continuous-Type ), BELL(Bell-Type), and TA (Tension Annealing; Continuous-Type ) furnaces. Annealing for internal stress removal is also possible as well as soft annealing. Moreover, according to our accumulated experience and know-how, we can control the size of metallographic structure (carbide grain size).
Bonding	A rolling mill to bond two or more types of metals (cladding). Clad metals are different from platings in that the metallic layers can be made thicker, the interface is bonded stlongly by diffusion bongding. Over-lay cladding, In-lay cladding, and Edge-lay cladding are available.
Functional pre-coating ("OVIONE®")	This equipment coats resin coating onto the base metal. The type of resin can be chosen to add the characteristics of your demand, such as insulation, sliding, light-proof, or other properties that metals don't have.
Molten solder plating	This equipment plates melted solder onto the base metal. Melted solder differs from tin plating in that the diffusion bonding at the interface enables very strong adhesion, and it can be All of our melted solder is lead-free.
Multigage skiving	Skiving the metal surface by a cutting tool form an uneven cross-sectional shape. Our skiving method ensures precise measurements and enables small production quantities.
Visual inspection	We conduct visual inspections, if necessary.
Slitting	Saitama plant has 7 different type of slitting machines, so we use the appropriate machinery for your metals and specifications. We can guarantee high quality slitting, like width tolerance and burr by setting optimum conditions for each metal's specification.
Sample inspection	We have furnished all the measuring equipments for mesuring metal properties and specifications, such as hardness and tension, etc. We also possess SEM (Scanning Electron Microscopes ) with EDX function. Furthermore, we have FE-SEM (+EBSD+EDS) which is more precise than SEM, so we can analyze micro crystal structure, too.
Packing	In order to prevent damage, rust, or other flaws arising in our products under transit, we alter our package one by one. We also accept specific packaging requests from you.
