Industrial Mold Marking & Engraving Machines: Permanent, Damage-Free Identification.

Molds represent the most expensive assets in manufacturing. Incorrect marking methods can cause micro-cracks or rapid wear during die casting. HeatSign provides industrial-grade marking equipment specifically designed for high-hardness tool steel (HRC40-HRC65+), ensuring permanent traceability in extremely harsh production environments while 100% protecting mold cavity integrity.

Why Standard Equipment Fails (And How We Solve It)

Conquering Extreme Hardness

Marks Molds Up to HRC60+. Heat-treated tool steels will instantly destroy standard engraving bits. HeatSign utilizes heavy-duty tungsten-carbide Dot Peen styluses to punch through metals up to HRC60, and 100W High-Power Fiber Lasers to effortlessly vaporize materials exceeding HRC60+.

Zero Surface Distortion

Protects Your Mold Cavity. Mechanical stamping can create micro-cracks that transfer defects to every single molded part. Our Fiber Lasers utilize a 100% non-contact, stress-free process to carve high-resolution QR codes and logos without altering the mold’s structural integrity.

Surviving the Molding Cycle

Permanent, Deep Traceability. Molds endure extreme heat, high injection pressures, and corrosive release agents that easily erase shallow marks. Both our Dot Peen and Laser systems deliver deep, wear-resistant engravings guaranteed to remain legible for the entire lifecycle of the mold.

Machine Selection Matrix: Which System is Right for Your Molds?

Choosing the wrong machine for your mold’s hardness or location can lead to ruined cavities and scrapped parts. Use this quick comparison matrix to confidently select the exact industrial tool you need:

Technology & Application Comparison

Core Specification	DE01 Electric Dot Peen (Deep Etching)	HS-FL100M 100W Fiber Laser (Precision)
Target Application	Exterior: Mold Bases, Sliders, Small and medium Castings	Interior: Core Cavities, Precision Inserts
Max Hardness	HRC60	Exceeds HRC60 (Up to HRC65+)
Marking Depth	0.05mm~ 0.8mm （depends on material hardness）	High-Precision Micro-Etching (almost no damage)
Initial Cost	Lower (Starting at $2,000)	Higher (Starting at $5,000)
Operating Cost	Very Low (Occasional stylus replacement only)	Zero Consumables (50,000-hour lifespan)

The Final Decision Guide

👉 Choose the DE01 Electric Dot Peen Marker if: You are on a strict budget and your primary need is stamping deep, highly durable serial numbers and batch codes onto the exterior mold base. It delivers heavy-duty physical marks that survive severe industrial abuse at the lowest possible entry cost.
👉 Choose the HS-FL100M 100W Fiber Laser if: You need to engrave high-resolution QR codes,batch numbers, microscopic logos, or anti-counterfeit marks directly inside high-hardness core cavities (HRC60+). The massive 100W power vaporizes ultra-hard tool steel instantly, ensuring 100% stress-free, non-contact engraving that completely protects the integrity of your mold cavity.

Frequently Asked Questions

Can your machines really mark hardened tool steel above HRC60?

Yes. we recommend the fiber laser engraver from 30W to 100W, can mark on any hard metals.

Will laser engraving damage the precision finish of my mold cavity?

No. The MOPA Fiber Laser is a 100% non-contact process. It vaporizes the surface material at a microscopic level without introducing mechanical stress, heat-warping, or micro-cracks, perfectly preserving the structural integrity of your delicate cavities.

Will the markings survive the extreme heat and pressure of injection molding?

Absolutely. Both technologies are designed for industrial depth. The DE01 creates deep physical indentations to survive extreme mechanical abrasion on mold bases, while the 100W laser provides deep-etched permanent marks. Your traceability codes will remain legible for the entire lifecycle of the mold.

My mold cores are cylindrical. Can the machine mark on curved surfaces?

Yes. Both the DE01 Dot Peen and our Fiber Lasers can be equipped with high-precision rotary axes. Our software automatically calculates the curvature, allowing you to seamlessly wrap serial numbers, texts, and logos around cylindrical parts without any stretching or focal distortion.

How do I mark massive, multi-ton mold bases that won't fit on a desk?

We understand that molds are heavy. While our standard setups are perfect for inserts and cores, HeatSign also offers portable, handheld configurations for both our Dot Peen and Fiber Laser systems. You can simply bring the marking head directly to the heavy mold base on your factory floor.

Can the software automatically update batch numbers and generate QR codes?

Yes. Our intuitive software supports dynamic data linking. You can easily import Excel CSV files to automatically generate sequential serial numbers, dates, shift codes, and scannable 2D DataMatrix/bar codes, eliminating human error.

Stop Risking Your Expensive Molds. Let Us Prove Our Machines on Your Toughest Steel.
