Tired of Mold Components That Fail at the Micro Level?
When your design calls for micro-holes with tolerances under 0.01mm, standard machining simply isn’t enough. Issues like tool breakage, hole drift, and poor surface finish can scrap entire batches, delay your project, and inflate costs. At [junjie mold parts], we specialize in turning these microscopic challenges into your competitive advantage.

The 3 Biggest Hurdles in Micro-Hole Machining (And How We Overcome Them)

  1. Tool Breakage & Deflection: Standard drills flex and snap under pressure. Our Solution: We utilize Swiss-type CNC lathes and custom-ground tungsten carbide micro-tools that excel at high-speed, high-precision drilling.

  2. Heat Management & Burrs: Excessive heat melts edges and creates burrs. Our Solution: Our through-spindle coolant system delivers high-pressure coolant directly to the cutting point, ensuring clean edges and minimal post-processing.

  3. Accuracy & Consistency: Maintaining ±0.002mm tolerance across hundreds of parts is demanding. Our Solution: Every part is verified with our optical comparators and CMM (Coordinate Measuring Machine) to generate a real-time inspection report.

Our Process: Precision by Design, Not by Chance
We don’t just machine parts; we engineer reliability.

  • Step 1: DFM Analysis (Free with Your Inquiry): Our engineers review your 3D files to identify potential manufacturing issues before production begins, saving you time and money.

  • Step 2: Right Tooling Selection: We select from our inventory of specialized micro-tools based on your material (e.g., P20, H13, Stainless Steel) and hole specifications.

  • Step 3: In-Process Monitoring: Advanced machines with in-process gauging detect minute deviations and auto-correct in real-time.

  • Step 4: Final QC & Certification: You receive a comprehensive report including dimensional data and material certification with every order.

Case Study: Enabling Miniaturization in Medical Devices
A European client needed a core pin with ten Ø0.12mm gas vent holes for a diabetic pen injector. Their previous supplier had a 40% failure rate.

  • Our Approach: We recommended a specific polishing technique for the hole interior to prevent material hang-up.

  • The Result: We delivered 5,000 pins with 100% dimensional conformity and a surface finish of Ra 0.1 µm. The client reported zero failures in their production run and has since made us their sole supplier for precision components.
