Engraving and Texturing Moulds Using Laser Technology Explained
Vidhata Plastics India Pvt. Ltd.
Manufacturing Complex Injection Moulds and Precision Plastic Parts Using Cutting Edge Technology.
Laser technology has transformed the way moulds are engraved and textured, enabling unmatched precision, durability, and surface optimization. At the forefront of this innovation, Vidhata Plastics, a leading plastic injection mould manufacturer in India, utilizes advanced laser techniques to create moulds with superior surface properties, ensuring better polymer flow, enhanced wear resistance, and flawless component finishes.
Why Choose Laser Technology for Mould Engraving and Texturing?
Traditional methods like EDM (Electrical Discharge Machining) and chemical etching have limitations in precision, consistency, and surface quality. Laser-based engraving and texturing, on the other hand, offers:
? Ultra-Fine Precision – Creates textures down to 200 nm, improving polymer adhesion, friction control, and aesthetic details.
? Non-Contact Processing – Ensures uniform engraving on complex 3D geometries without mechanical stress.
? Cold Ablation Technology – Ultrafast lasers prevent heat damage, preserving the material's integrity.
? Custom Surface Engineering – Enables self-cleaning, hydrophobic, or friction-reducing textures.
Best Practices in Laser Engraving and Texturing at Vidhata Plastics
To achieve the highest standards in engraved and textured moulds, Vidhata Plastics follows these advanced techniques:
1. Selecting the Right Laser for Precision Engraving
Different materials require different laser parameters. Vidhata Plastics optimizes:
?? Fiber Lasers (1.06 μm) – Best for deep engraving in hardened steels (H13, P20, S136).
?? CO? Lasers (10.6 μm) – Ideal for non-metallic moulds like epoxy composites.
?? Femtosecond Lasers (<350 fs) – Ultra-fast pulses prevent heat damage, perfect for high-precision microtextures.
2. Advanced Scanning Techniques for Consistent Textures
To ensure uniform and accurate textures, Vidhata Plastics uses:
?? Vector Scanning – Controls groove depth for detailed engraving.
?? Raster Scanning – Covers large areas evenly with parallel hatch patterns.
?? Beam Modulation – Adjusts laser pulse overlap (40–60%) to prevent inconsistencies.
3. Material-Specific Optimization for Best Results
Each mould material interacts differently with laser energy. Vidhata Plastics tailors settings to:
? Steel & Alloys – Uses ultra-short pulses to prevent thermal stress.
? Aluminum & Copper – Adjusts pulse intensity to counteract high reflectivity.
? Ceramics & Composites – Uses UV/mid-IR lasers for controlled microstructural changes.
4. Surface Preparation for Better Adhesion
Before engraving, the mould undergoes:
? Plasma Cleaning – Removes oxides and contaminants.
? Electrochemical Surface Activation – Enhances laser absorption.
? Cryogenic Pre-Treatment – Stabilizes material properties for long-lasting textures.
5. Multi-Layer Processing for Enhanced Depth Control
By applying multiple laser passes, Vidhata Plastics ensures:
?? Hybrid Texturing – Combines micro-grooves with nano-patterns for optimal surface function.
?? Optimized Surface Energy – Improves polymer release, reducing defects.
?? Stronger Mould Durability – Ensures longer-lasting textures with better mechanical strength.
6. Real-Time Quality Monitoring for Flawless Results
Vidhata Plastics integrates smart monitoring systems to maintain unmatched precision:
?? Optical Coherence Tomography (OCT) – Measures engraving depth with ±2 nm accuracy. ?? Thermal Imaging Sensors – Detects heat accumulation to prevent cracking.
?? AI-Based Feedback Systems – Dynamically adjusts laser settings in real time.

7. Post-Processing for Maximum Performance
After laser texturing, Vidhata Plastics enhances the mould with:
? Ion Beam Polishing – Reduces roughness for smooth part release.
? Plasma Coatings (DLC, TiN, CrN) – Improves wear resistance.
? Cryogenic Hardening – Strengthens moulds for extended production cycles.
