先搞清楚你在跟谁说话

• 终端设备商（如医疗器械、自动化设备厂商）：关心精度、材料认证、有没有做过同类产品
• 工程集成商/EPC：关心批量交付能力、交期稳定性、能否配合图纸定制
• 海外经销商/贸易商：关心价格梯度、MOQ、通用型号的现货能力

Subject: CNC machining for medical components — ISO 13485 certified, ±0.005mm tolerance

Hi [Name],

I noticed [Company] is developing next-gen surgical instruments — your recent product launch in minimally invasive tools caught our attention.

We specialize in high-precision CNC machining for medical devices, with ISO 13485 certification and capability to hold ±0.005mm tolerance on titanium and 316L stainless steel. We've been supplying machined housings and shaft components to medical equipment manufacturers in Germany and Japan for the past 6 years.

I'd be happy to share a few case studies with similar complexity, along with our material certifications. Would that be helpful?

Best regards,
[Your name]

• 第一句话提到他的具体产品方向，证明不是群发
• 用精度参数（±0.005mm）、材料（titanium/316L）、认证（ISO 13485）、已服务市场（德国/日本）建立专业度
• 结尾不推销，只提供案例和证书——这是设备商最需要的东西
  
  

Subject: CNC parts supply for your [industry] projects — 50+ alloys, 10-day prototype

Hi [Name],

Came across [Company]'s recent automation line installation in Southeast Asia — looks like an impressive scope of work.

We provide CNC machined components for industrial automation equipment, covering 50+ engineering alloys including aluminum 6061/7075, PEEK, and POM. Our typical lead time is 10 days for prototypes and 15-20 days for batch production.

We recently completed a batch of 2,000 custom aluminum brackets for a robotics integrator in the Netherlands, with full dimensional inspection reports. Happy to send over the project summary if relevant.

Best regards,

• 开头提到他的具体项目
• 用材料种类、交期天数、批量数量这些硬数字说话
• 提供同行业的项目案例——集成商最关心你能不能按时交货
  
  

Subject: CNC turned parts — factory direct, MOQ 100pcs, 7-day standard items

Hi [Name],

I saw your product catalog on [website/trade show] — you carry a wide range of industrial hardware and precision components.

We manufacture CNC turned and milled parts with a monthly output of 200K pcs. For distribution partners, we offer tiered pricing starting from MOQ 100pcs, with standard fasteners and fittings available within 7 days.

Can I send you our product list and price tiers for a quick comparison with your current suppliers?

Best regards,

• 经销商不需要听你的技术故事，直接亮出MOQ、产能、交期
• "comparison with your current suppliers"——降低心理门槛，不是让他换供应商，是多一个选项

跟进不是追问，是持续提供新信息

Hi [Name],

Following up on my earlier note. I wanted to share a technical brief on surface finish options for medical-grade CNC parts (Ra 0.4-1.6μm achievable), which might be relevant to your current design specs.

Happy to send it over if helpful.

Hi [Name],

I thought this might be useful — we put together a comparison chart of lead times and cost factors for titanium vs. stainless steel CNC components. Several clients found it helpful for early-stage design decisions.

Would you like me to share it?

Hi [Name],

Quick question — are you currently sourcing any CNC machined components from China? If so, how has your experience been with lead time consistency and dimensional accuracy?

We've been helping several [market] companies address these issues, and I'd be curious to hear your perspective.

Hi [Name],

I'll keep you posted on any new capabilities or material options we add. Feel free to reach out whenever you need a quote or technical support.
