The PETRA 10-Digit Auto Numbering Machine is a heavy-duty, self-inking metal stamp engineered for high-volume document control, manufacturing serialization, and transactional tracking. This robust office tool automates the process of repetitive sequence labeling by shifting numbers forward mechanically with each stamp press.

Core Specifications & Mechanics

• 10-Digit Capacity: Accommodates large serial strings up to 10 numerical characters, making it perfect for tracking expansive batches or long ledger numbers.
• Zinc Alloy Construction: Built with a solid, professional-grade zinc alloy body that resists denting, rusting, and wear under continuous daily use.
• Self-Inking Mechanism: Uses an internal ink pad that automatically slides across the custom digit die before each press, eliminating messy external ink wells.
• Ergonomic Handle: Wrapped with a shock-absorbing rubber grip that diminishes hand fatigue over prolonged multi-page labeling sessions.

Common Applications

• Accounting & Banking: Applying unique audit trails to transaction sheets, checks, and ledgers.
• Manufacturing & Supply Chain: Stamping sequential batch and lot numbers on packaging or material logs.
• Ticketing & Logistics: Managing custom entry sheets, raffle coupons, or shipping bills of lading
