Recently, ten customised Spot Welding Electrodes from FANMETAL were shipped from Qingdao Port to Port Klang in Malaysia, and successfully delivered to a local precision machinery manufacturer. Tailored to address the client's core challenges in electrical discharge machining (EDM), this batch of products not only passed Malaysia's stringent import compliance checks but also earned high praise from the customer for its stable performance, further consolidating FANMETAL's position in the Southeast Asian market.
Challenges Faced by the Client
The Malaysian client, specialising in precision machining of automotive components, encountered three major difficulties when using conventional electrodes:
- Firstly, the brittle nature of tungsten-copper material caused non-standard inlay structures to crack during machining, resulting in a scrap rate exceeding 15%.
- Secondly, insufficient thread precision in the electrodes led to torque decay during high-temperature EDM processing, compromising machining stability.
- Thirdly, unfamiliarity with Chinese tungsten product export regulations and Malaysian import compliance requirements raised concerns that non-compliant documentation could cause container delays.
FANMETAL's Solution
- Technically, the preheating homogenisation process eliminates internal material stresses. Combined with diamond-coated tools and a high-pressure cooling system, this achieves micro-thread machining tolerances within ±0.005mm, completely resolving cracking and precision issues.
- Regarding compliance, we proactively arrange dual-use export licences from the Ministry of Commerce, assist clients in preparing resource tax payment certificates and heavy metal testing reports, ensuring compliant and efficient customs clearance while mitigating risks associated with stringent port inspections in Malaysia.
Precision Manufacturing
This batch of Tungsten Copper Electrode was produced using an integrated powder metallurgy process, adhering to stringent quality control standards throughout. Raw materials comprised 99.95% purity tungsten powder and highly conductive copper powder, blended uniformly in a planetary ball mill according to customer specifications. This ensured tungsten content remained stable within the 75%-80% range, balancing hardness and electrical conductivity. The forming stage employs cold-pressed sintering technology, with sintering conducted under vacuum at 1450°C. Subsequent CNC grinding and EDM wire cutting ensure an inlay surface conformity of 99.8%. Finished products undergo tensile strength (≥920MPa), thermal conductivity (≥170W/m·K), and thread torque testing, with all metrics meeting international EDM machining standards.
Our Company's Multi-Dimensional Advantages
As an enterprise with over a decade of specialised experience in non-ferrous metals trade, FANMETAL has earned the trust of overseas clients through three core strengths:
- Firstly, our technical customisation capability allows us to adjust tungsten-copper ratios and structural designs according to clients' processing materials (such as high-chromium stainless steel or titanium alloys), addressing non-standard operational requirements;
- Secondly, our comprehensive service system covers the entire process from initial client enquiries to solution proposals and quotations, followed by production, packaging, and dispatch, culminating in efficient after-sales support and technical consultation to resolve all client concerns.
- Thirdly, our end-to-end trade services include bespoke logistics solutions and a 48-hour emergency response mechanism, enabling effective management of port policy changes and congestion issues across Southeast Asia.
Highly Commended by the Client
'The new batch of electrodes operated without a single fault during 2,000 consecutive hours of EDM machining, reducing scrap rates to below 1% while boosting production efficiency by 30%.' The procurement manager of this Malaysian client stated that the compliant delivery process and product performance exceeding expectations have laid the foundation for long-term collaboration between both parties, with plans already in place to place additional purchase orders for the next quarter.
Conclusion
This delivery not only validates FANMETAL's technical prowess in precision tungsten-copper products but also enhances our service infrastructure across the Southeast Asian market. Moving forward, our company will maintain its focus on the non-ferrous metal deep processing sector, optimising products and services to meet overseas client requirements while supporting local manufacturing upgrades. Naturally, we also supply other tungsten-copper alloy products, including rods, plates, and tubes.
