Key Advantages
Micron-Level Diamond Pattern Replication
Using electroforming—via photolithography and electrolytic deposition—we replicate intricate diamond patterns with line width as fine as 0.05mm and tolerance ±0.002mm. This ensures that seals made from our molds feature sharp, consistent patterns (e.g., micro-text, anti-counterfeit lines) that are difficult to forge, meeting national seal security standards (e.g., China GB/T 22388, EU EN 16582).
Electroforming Excellence for Seal Durability
High-purity nickel (99.95%) and nickel-cobalt alloy materials offer superior corrosion resistance (passes 5000h salt spray test) and wear resistance, enabling the molds to withstand ≥100,000 stamping cycles without pattern degradation. This is critical for mass-producing consistent, long-lasting seals for government agencies and enterprises.
Full Customization for Seal Specifics
We tailor molds to match diverse seal requirements:
- Patterns: Custom diamond textures (linear, grid, radial), integrated logos, or security micro-text (0.1mm font size) for anti-counterfeiting
- Sizes: From small corporate stamps (φ10-30mm) to large official seals (φ50-100mm), compatible with rubber, resin, or metal seal materials
- Surface Finish: Mirror-polished (for high-sharpness replication) or matte (for reduced glare in optical inspection)
Seal-Specific Performance
Our electroformed molds ensure that seal patterns maintain clarity after repeated stamping (ink adhesion test: ≥95% pattern coverage). The diamond patterns enhance ink retention, preventing smudging and ensuring legibility on documents, certificates, and official papers.
Application Scenarios
- Official Seals: Molds for government, judicial, and administrative agency seals requiring strict pattern accuracy and anti-counterfeiting features
- Corporate Stamps: Molds for company chops, financial seals, and contract stamps, with custom logos and registration numbers
- Anti-Counterfeiting Seals: Molds for high-security seals (e.g., notary public stamps, customs seals) with micro-diamond patterns detectable via optical scanners
Our Service Commitment
- Rapid Prototyping: 5-7 days for mold prototypes, with 3D microscopic inspection to validate pattern precision
- Design Support: Bilingual engineers assist with pattern optimization (e.g., adjusting diamond density for ink flow) based on client seal materials (rubber, metal, resin)
- Quality Certifications: ISO 9001 certified, with full traceability for material purity (certified by SGS) and production processes
Whether you need molds for standard corporate stamps or high-security official seals, our high-precision diamond pattern electroformed molds deliver the accuracy, durability, and anti-counterfeiting performance your seal production demands.
