Plastic Injection Molding
GET THE MOST COST-EFFECTIVE WEAR & CORROSION RESISTANCE–
INCREASE TOOL LIFE BY 2-10 TIMES
Dynamic’s surface treatments improve part quality, reduce post-processing, and dramatically extend tool life for plastic injection molds—especially those running abrasive or glass-filled materials.
Durable Surface Treatments for High-Volume, High-Wear Molds
Injection mold tooling is under constant wear, corrosion, and erosion from increasingly aggressive materials like glass-filled or mineral-loaded resins. These compounds quickly degrade untreated steel surfaces, leading to flash, high wear, poor part quality, and costly rework.
Dynamic’s diffusion-based treatments penetrate up to .020″ deep with a 75+ HRC surface-providing unmatched resistance to wear, erosion, corrosion, and better release. Whether you’re running high-glass content, long strand fiberglass, rubber, or PVC, DYNA-BLUE & DYNA-BRITE helps your tools perform better and last longer.
“DYNA-BLUE® has become a best practice at LDM Technologies for good reason. We reduced our monthly tooling budget from $70,000 to just $6,000, and eliminated the need for deburring knives entirely—dramatically improving plant safety by removing sharp flash at parting lines. Our part component defect rate dropped from over 36 PPM to single digits. One mold running 30% glass-filled polypropylene surpassed 2 million cycles without requiring replacement. When Ford requested an engineering change and offered $360,000 for new tooling, we confidently told them it wasn’t necessary. DYNA-BLUE® helped us save the customer nearly half a million dollars—without ever compromising performance.”

Why DYNA-BLUE® & DYNA-BRITE for Injection Molding?
DYNA-BLUE® and DYNA-BRITE
Molding Challenges We Solve
-
Wear of molding components
-
Flash and parting line degradation
- Poor part release sticking
- Corrosion from moisture, cooling water, or caustic plastics
- Surface wear from abrasive fillers such as glass or mineral
- Texture wear or loss of gloss level
- Excessive mold polishing and cleanup time
Our treatments penetrate the steel, creating a 75+ HRC compound layer with a deep nitrogen-rich support zone—without the risk of flaking, chipping, or geometry distortion. This makes them ideal for complex and multi-cavity molds with waterlines, ribs, vents, or ejector sleeves.
Key Benefits:
-
Resists wear from glass-filled plastics up to 10X longer than nitriding
-
Handles harsh resins like PVC, acetal, and flame-retardant compounds
-
Uniform coverage, even in deep holes or ribs
-
Maintains sharp edges and ejector fit
-
Low dimensional change: 0.0001″–0.0002″ per side
-
Supports Class A finishes and high-gloss surfaces
-
Can be combined with DYNA-GLOSS™ or DYNA-BRITE™ for textured or polished molds
-
Compatible with stainless, tool steels, and pre-hardened grades
