Introduction
Mould texturing is an advanced surface treatment process used in the manufacturing of plastic, metal, or composite moulds. It involves creating fine patterns, designs, or surface finishes on the inner surface of a mould. These textures are then transferred to the final product during the moulding process, giving it an attractive appearance, better grip, and improved functionality.

This technique is widely used in industries like automotive, electronics, luggage, home appliances, and packaging to add both beauty and value to products.


What is Mould Texturing?

Mould texturing is the process of adding surface patterns or finishes to moulds using various methods such as chemical etching, laser texturing, or sandblasting. Instead of leaving the product surface plain and glossy, texturing allows manufacturers to create a matte, leather-like, or patterned surface that enhances both look and feel.

For example, in suitcase manufacturing, mould texturing can give a rugged leather texture, while in automotive interiors, it provides a soft, matte touch that hides scratches and fingerprints.


Purpose of Mould Texturing

The main goals of mould texturing are:

  • Aesthetic enhancement: Makes the final product visually appealing.
  • Improved grip and feel: Adds texture for better handling.
  • Scratch and wear resistance: Hides small defects and increases surface durability.
  • Reduced glare: Matte textures reduce light reflection.
  • Easy demoulding: Certain textures help parts release easily from the mould.
  • Brand identity: Unique textures can reflect a company’s design style or logo pattern.

  1. Chemical Etching:
    Uses acid-based chemicals to etch patterns into the mould surface. It’s ideal for fine, detailed, and uniform textures.
    • Commonly used for suitcase, automotive, and plastic component moulds.
  2. Laser Texturing:
    Uses high-precision laser beams to engrave patterns. It allows for extreme detail, consistency, and custom designs such as micro-patterns or logos.
  3. Sandblasting / Grit Blasting:
    Involves shooting fine abrasive particles at high speed to roughen or dull the surface. This gives a matte or frosted appearance.
  4. Electrical Discharge Texturing (EDT):
    Uses electrical sparks to create a controlled rough surface on the mould. It’s suitable for metallic textures and industrial applications.

Step-by-Step Mould Texturing Process
  1. Surface Preparation:
    The mould surface is cleaned and polished to remove dust, oil, or residues. This ensures the texture adheres properly.
  2. Masking or Pattern Application:
    A photoresist or masking film is applied to protect the areas that should not be textured.
  3. Texturing (Etching / Laser / Blasting):
    The chosen texturing method is applied to create the pattern or finish on the exposed areas.
  4. Cleaning and Neutralizing:
    After texturing, chemicals or residues are neutralized and the surface is thoroughly cleaned.
  5. Inspection and Finishing:
    The mould is checked for texture depth, pattern quality, and uniformity. Any imperfections are corrected before final polishing.

Types of Mould Textures
  • Leather Grain Texture: Looks like natural leather; common in car interiors and suitcases.
  • Matte / Satin Texture: Soft, low-gloss finish used in electronic housings.
  • Geometric Pattern: Modern, structured look for premium products.
  • Wood Grain Texture: Gives a natural, elegant look to plastic surfaces.
  • Custom Design Texture: Brand-specific patterns, logos, or decorative styles.

Benefits of Mould Texturing
  • Enhances product appearance and feel
  • Improves scratch and wear resistance
  • Reduces visibility of flow lines or weld marks in moulded parts
  • Improves grip and anti-slip properties
  • Helps differentiate products through unique surface designs
  • Increases customer appeal and brand value

Applications of Mould Texturing

Mould texturing is used across many industries:

  • Automotive: Dashboard panels, steering wheels, bumpers, and door trims
  • Luggage: Suitcase shells, handles, and trims
  • Consumer Electronics: Mobile covers, laptop panels, and home appliance parts
  • Medical Devices: Handheld equipment and grips
  • Household Products: Containers, furniture parts, and packaging

Maintenance of Textured Moulds

To preserve the quality and life of textured moulds:

  • Avoid using sharp tools for cleaning.
  • Use soft brushes or mild cleaning agents.
  • Regularly inspect for wear, corrosion, or buildup.
  • Apply protective coatings if necessary.

Proper maintenance ensures the texture remains sharp and consistent over multiple production cycles.


Conclusion

Mould texturing is more than just a decorative step—it’s a crucial process that enhances both the appearance and performance of moulded products. With methods like chemical etching and laser texturing, manufacturers can achieve precise, high-quality finishes that elevate their product standards. Whether for a sleek electronic gadget or a stylish suitcase, mould texturing adds that final professional touch that customers notice and appreciate.
