KOREA TUNGSTEN CO.,LTD

Made to drawing or sample

Send us a drawing or a sample and we will confirm whether we can machine it and reply.

OVERVIEW

Most of what Korea Tungsten machines is made to order. Send us a drawing or a sample and we will review whether to make it by 3D machining, wire machining, MCT or CNC, and answer quickly and precisely.

Whether it is a small order or a repeat quotation, please feel free to ask. We make to the design and purpose you want, and handle anything from a single prototype to full production.

Tungsten and molybdenum have high melting points and break easily at room temperature. Even with the same drawing, tools and conditions have to be set again for each material and geometry, which makes deciding the machining method a development task in itself.

SCOPE

Scope

STEP 01

Drawing received

Send us a drawing and we will review the specifications and tolerances.

STEP 02

Sample submission

A physical sample alone is enough — we take the dimensions off it and machine.

STEP 03

Reply on feasibility

We go through which processes to combine with you.

STEP 04

Small and repeat orders

A single prototype and a repeat quotation are both welcome.

We take the customer's requirements and drawing, review the material, decide which processes to combine and how, then build a prototype. Conditions are revised as we review the results, and the method builds up through that cycle.

A representative development case

Chrome copper · tungsten composite electrode

A resistance welding electrode: a high-purity tungsten tip, chosen for high-temperature strength and wear resistance, bonded to the end of a chrome-copper body with good electrical conductivity and heat dissipation. The job was to make two metals with completely different properties into one part.

Technical challenge

The first challenge was bonding chrome copper and tungsten — two metals with completely different physical properties — without any gap. After bonding, the long, slender tip had to be machined to fine dimensions with the center axis still true.

Machining steps

We ran the bonding process, then combined turning and step machining, then fine machining of the tip. The work called for both hard-metal machining know-how and the ability to design a combined process.

Result

We achieved a defect-free bond and a tip that meets the drawing specification. The clean step profile and the precise tip groove translate into current focusing efficiency and part life in high-temperature resistance welding.
