Core Technology of SodickSodick develops & manufacturers all core technology in house.
Sodick manufactures Wire electrode used for W-EDM
＊Sodick has many group companies. One of them manufactures Wire electrode.
＊ Wire electrode holds key for EDMing quality.
＊ With an EDM experience of many years, Sodick started manufacturing wire electrode and can utilize a vast knowhow stored in developing, designing and manufacturing EDM during the past many years.
＊ Sodick is the only manufacturer in Japan who manufactures wire from A to Z. (Others purchase wire strand anddraw wire into the size.)

• Sodick EWS manufactures wire electrode from fusion to finished wires in-house.• Sodick projected from beginning to have a complete production line for the following
reasons.
Reasons：１．Sodick can improve quality by adjusting raw material percentage.２．Better quality can be achieved and maintained easily (This process
needs a long experience in EDM development, manufacturing andoperation.
３．Can reduce cost.４．Sodick can hold responsibility for product (quality control for each process
and operation efficiency) and also shorten delivery
Why is Total Manufacturing Required in One Factory?

Manufacturing
Process
Quality Control ( Melting)＊This process is to make Φ8.0mm wire strand by melting Pure copper & pure Zinc.＊For high quality brass, componential analysis are performed in every fusion process.

Inspection
Tension testby tension tester
After machine oxidizes wire surface, Φ8.0mm is drawn to secondary Φ3.0mm
The wire of Φ8.0mm is drawn to Φ3.0mm and further drawn to Φ0.9mm diameter wire

⑨ Set Φ0.9mm Wire strand
＊Φ0.9mm diameter wire is drawn to .07,Φ0.10,Φ0.15,Φ0.20,Φ0.25,Φ0.30＊Through this process, diameter, tensile strength and elongation are determined

Manufacturing
Process
Quality Control (Wire drawing)• Each product is carefully inspected for wire diameter , weight, curl, tensile strength,and also visually
inspected. * Moreover, the product data is stored in software developed in-house.
Curl inspectionWire is cut in 1m and inspected for straightness.
All products are inspected and its data is stored.
Tensile strengthis tested on tensiletester.
Surface is tested by microscope to check scratch, dirt, stain, deformation, etc.
Outer check to check dirt on bobbin, color change.
Weight is measured on scale.Diameter and roundness are measured by laser.
Manufacturing
Process
Quality Control (Packing)* Rust-proof paper is rolled around inspected product, and shrink-wrapped.* Bar-code is utilized to manage product labeling and packaging
Wire products after inspection
Inspection
External appearance testAfter checking bobbin and labeling, wires are wrapped by rust-proof paper and shrink-packed to avoid corrosion and moisture.
Shrinking Packaging
ShipmentTo avoid mixed packagingBoxes and wires are managed by bar-code.
Power of EDM Specialized Manufacturer
• To produce most suitable wire for EDM, wire is annealed to have satisfactory tensile strength and elongation.
• The wire is evaluated in application sector in Sodick group company.
