Chemical Etching Process for Mould Components & Precision Tooling
We provide professional chemical etching process for moulds and tool room components where accurate depth, clean edges, and uniform texture are required.
Our chemical etching is widely used in:
- Injection mould cavities
- Core inserts
- Slider plates
- Date stamps & identification marks
- Air Cut Pattern
- Micro-texture surfaces
Tool rooms across India trust our Chemical Etching Services for burr-free and stress-free mould processing.
What Is Chemical Etching in Mould Industry?
Chemical etching is a controlled metal removal process used to create markings, patterns, or shallow textures on mould steel.
It removes metal without:
- Mechanical cutting
- Heat damage
- Surface cracking
- Tool pressure
Because there is no cutting force, the mould surface remains stable and accurate.
In many projects, chemical etching is used before:
- 3D Surface Etching for deeper textures
- PTFE Non-Stick Coating for mould release improvement
- 5-Axis Laser Texturing for detailed pattern work
Why Mould Makers Prefer Chemical Etching
Chemical etching is important in mould industry because:
✅ No burr formation inside cavity
✅Uniform depth across flat or curved surfaces
✅No heat-affected zone
✅Safe for hardened tool steels (P20, H13, etc.)
✅ Ideal for venting lines and micro textures
It is especially useful where machining or laser may cause tool marks or heat stress.
Step-by-Step Chemical Etching Process for Moulds
Step 1: Mould Inspection
We inspect mould material, hardness, and required depth.
Step 2: Surface Cleaning
Complete degreasing and oxidation removal for accurate etching.
Step 3: Masking & Photoresist Coating
Only required areas are exposed for etching.
Step 4: Controlled Chemical Etching
Depth is controlled in microns to maintain mould tolerance.
Step 5: Neutralization & Cleaning
Chemicals are removed safely.
Step 6: Final Inspection
Surface depth and finish are verified before delivery.
Mould Materials Suitable for Chemical Etching
We commonly etch:
- P20 Steel
- H13 Tool Steel
- Stainless Mould Steel
- Mild Steel
- Aluminium Mould Blocks
- Brass Mould Alloy
- Copper Mould Material
- Stavax Stainless Mould Steel
This process works safely even on hardened mould components.
Applications in Mould Industry
Chemical etching is widely used in:
- Injection mould cavities
- Mold branding logos
- Date coding inserts
- Anti-slip or micro-texture patterns
- Vent channels
- Decorative surface preparation
For deeper textures, we combine chemical etching with 3D Surface Etching or 5-Axis Laser Texturing.
Chemical Etching vs Laser for Moulds
| Feature | Chemical Etching | 5-Axis Laser Texturing |
| Large cavity areas | ✅ Good | ⚠️ Slower |
| Fine vent lines | ✅ Excellent | ⚠️ Limited |
| Deep 3D textures | ❌ Limited | ✅ Excellent |
| Heat impact | ❌ No | ⚠️ Possible |
💡 Many mould makers use both processes depending on requirement.
