Equipment Name: Professional Pad Printing Machine for Screwdrivers
Core Advantages:
- High-Precision Positioning: The servo dual-axis rotation structure ensures a printing positioning accuracy of ±0.01mm with minimal registration error.
- High Efficiency & Environmental-Friendliness: Four-color independent cylinder synchronous printing boosts efficiency by 50%; the eco-friendly cup-type ink cup design reduces ink waste by over 20%.
- Automated Operation: Equipped with pneumatic automatic clamping fixtures and a Mitsubishi HMI touch screen, parameter adjustment is convenient and requires zero manual intervention.
- Safety & Reliability: A safety light curtain comes as standard, which detects the operation area in real time and automatically stops the machine in case of accidental contact, ensuring production safety.
- Strong Durability: Core components including Mitsubishi PLC and motors guarantee a service life of ≥ 8 years with low maintenance costs.
Scope of Application: Multi-color printing of screwdrivers, small hardware parts, and steel/stainless steel workpieces.
Application: Screwdrivers are widely used in scenarios such as daily maintenance, industrial assembly and construction. Printing requirements mainly focus on brand logos, specification markings and warning colors.
Materials: The main body of the workpiece is made of steel/stainless steel (needing printing on flat/curved surfaces), and the handle is made of plastic/rubber (requiring wear-resistant printing).
Geometric Features: Small size (≤100×200mm), combination of multiple curved and flat surfaces, and compact printing area (≤60×60mm).
Common Risks: Manual printing is prone to position deviation, inaccurate color registration, ink leakage and contamination, as well as high rejection rate (≥15%).
- Low Efficiency: Manual printing yields ≤ 1,000 pieces per shift, failing to meet the delivery requirements of bulk orders.
- High Cost: The labor cost per workpiece is 0.5 yuan, coupled with a 15% rejection rate, resulting in an additional monthly loss of over 20,000 yuan.
- Poor Precision: Manual positioning error is ≥ 0.1 mm, leading to blurry brand logos that undermine product image.
- Environmental Issues: Traditional ink tray systems cause excessive ink waste (≥ 20%) and are prone to leakage, which results in workshop contamination.
Rough Machining (Screwdriver Workpiece Preparation) → Automatic Loading (Pneumatic Cylinder Clamping) → 4-Color Synchronous Printing (Servo Dual-Axis Rotation) → Drying (Optional) → Quality Inspection → Automatic Unloading
- Automatic Loading: Equipped with pneumatic cylinder-driven automatic clamping fixtures, it eliminates the need for manual workpiece fixing and reduces operational errors (positioning accuracy is improved to ±0.01mm).
- Printing Stage:
- Servo Dual-axis Rotation Structure: Ensures precise alignment between workpieces and ink cups, with registration error ≤ 0.01mm.
- Eco-friendly Cup-type Ink Cup (90mm): The sealed design reduces ink volatilization and leakage, cutting ink consumption by over 20%.
- 4-color Independent Cylinders: Completes multi-color printing synchronously, shortening the single-cycle time to 5 seconds per piece.
- Quality Inspection: An optional inline vision system is available to identify printing defects (e.g., missing prints, blurriness) in real time, reducing the rejection rate to below 5%.
- Automatic Unloading: Automatically unloads workpieces after printing without manual intervention, achieving fully automated production throughout the entire process.

Case Study: A hardware tool factory in Zhejiang used to rely on 2 workers for manual screwdriver printing, with a per-shift output of 1,000 pieces and a rejection rate of 15%. After adopting this equipment, the per-shift output has increased to 1,500 pieces, the rejection rate has dropped to 5%, and the monthly savings in labor and defective product costs have exceeded 25,000 yuan.
Applicable Scenarios: Hardware tool factories, mass screwdriver production enterprises, custom tool brands, and small component printing factories.
