With 15+ years of expertise in precision mold components, we specialize in stepped die casting mold date stamps, electroforming processing, and full non-standard customization--catering to automotive, home appliance, and industrial die casting industries. Our products ensure accurate part traceability (batch dates, shift codes) and long-term durability in high-temperature, high-pressure die casting environments.

Stepped date stamps are critical for die casting part traceability--our designs excel in "precision + ruggedness" for harsh production environments:

• Stepped Structure Advantages: The multi-step design (customizable step heights: 0.5-5mm) allows clear stamping of multi-character codes (e.g., "231025" for batch dates, "A/B" for shifts) on die cast parts. Using electroforming, we achieve ±0.005mm step height accuracy, ensuring each character stamps uniformly without blurring--even on curved or textured part surfaces (e.g., automotive engine brackets, appliance panels).
• High-Temperature Durability: Made from electroformed nickel-copper alloy (hardness HV 450-500), our date stamps withstand 300℃ continuous contact with molten aluminum/zinc (common in die casting), resisting deformation or oxidation. This ensures consistent stamping quality for ≥100,000 cycles--reducing mold downtime for replacements.
• Compatibility with Die Casting Molds: Applicable to cold chamber die casting molds (aluminum parts) and hot chamber molds (zinc parts). We customize stamp dimensions (10-50mm length) and mounting interfaces (threaded, press-fit) to integrate seamlessly with existing molds, avoiding costly mold modifications.

Electroforming is uniquely suited for date stamps, delivering unmatched precision and performance:

• Micron-Level Replication: Our electroforming process (combining photolithography and electrolytic deposition) replicates intricate stepped features, character details (0.3mm fine lines), and surface textures with 99.9% accuracy. This eliminates burrs or uneven edges that could distort stamps, ensuring legible part traceability--critical for automotive VIN tracking or ISO 9001 compliance.
• Material Superiority: Electroformed nickel-copper alloy offers a balance of hardness (wear resistance) and ductility (shock absorption during stamping). Unlike traditional machined steel stamps, it resists galling (metal adhesion) when in contact with molten alloys, extending service life by 30% compared to standard options.
• Performance Validation: Every electroformed date stamp undergoes 1000h salt spray testing (no rusting) and thermal shock cycles (-40℃ to 300℃, 500 times) to ensure reliability in humid or high-heat die casting workshops.

We understand die casting molds vary--our customization service adapts to your unique needs:

• Full Range of Custom Options:
  • Dimensions: Length, width, step height (0.5-10mm) tailored to part size and stamp visibility.
  • Characters/Markings: Custom logos, batch codes, material grades, or regulatory symbols (e.g., "CE" for EU markets).
  • Mounting: Threaded holes (M3-M8), press-fit shafts, or magnetic bases for easy installation/removal.
• Streamlined Process: From client-provided drawings (CAD/STEP files) to sample delivery in 7-10 working days. Our engineers conduct DFM (Design for Manufacturability) checks to optimize step angles and character depth, ensuring compatibility with your die casting pressure (500-2000bar).
• Small-to-Large Batch Support: Whether you need 5 prototype stamps for R&D or 500+ for mass production, we maintain precision--each unit undergoes CMM inspection (dimensional tolerance ±0.01mm) before shipment.

• Rapid Turnaround: 15-day prototype delivery for urgent mold trials; 20-day lead time for mass production.
• Quality Assurance: ISO 9001 certified, with full traceability (material certificates, inspection reports) for each batch.
• Technical Support: Our mold engineers provide free consultation on stamp design, helping you balance visibility (legible stamps) and part integrity (avoiding stamp-induced cracks in thin-walled parts).
