Mold marking and engraving are vital for quality control and traceability in manufacturing. These processes create durable, precise markings on mold surfaces, ensuring accurate identification and compliance with industry standards.

This study examines the effectiveness of dot peen marking on molds with a hardness of up to HRC60. It also investigates the performance of fiber laser marking on molds that are even harder. We want to help you choose the best marking technology for your mold based on its hardness. We focus on mold marking, engraving, and machines.

What Challenges in Mold Marking and Engraving?

Varying Hardness of Molds

Molds can have hardness levels up to HRC60 and beyond. Softer molds are easier to mark, but harder molds require advanced marking solutions to ensure effective results without damaging the mold.

 

Need for Deep, Permanent, and Wear-Resistant Markings

Markings must be deep, permanent, and wear-resistant to withstand high temperatures, abrasion, and chemicals. Durable markings ensure long-term traceability and compliance with industry standards.

Ensuring Precision and Consistency in Markings

Precision and consistency are essential to avoid identification errors and production delays. Advanced technology is needed to maintain high accuracy in every marking, regardless of mold complexity or production volume.

 

Overcoming Limitations of Traditional Marking Methods

Traditional methods like manual engraving or stamping can be time-consuming and error-prone. Advanced technologies like dot peen and laser marking offer greater precision, efficiency, and reliability, overcoming these limitations.

What are Solutions for Mold Marking and Engraving?

Dot Peen Machine Marking
