Composition Moulding

Composition Moulding

Definition

Composition Moulding refers to frame moulding made from a mixture of resin, wood flour, and sometimes other additives. These mouldings are often designed to mimic traditional carved wood frames but are produced at a lower cost and with more uniformity.

Materials and Construction

• Resin: Provides structure and flexibility, allowing for intricate designs and durability.
• Wood Flour: Finely ground wood particles that give the moulding a wood-like texture and finish.
• Other Additives: Fillers, pigments, or stabilizers to improve strength, color, or surface properties.

Characteristics

• Mimics the appearance of carved wood or gilded frames at a fraction of the cost.
• Can be painted, gilded, or finished to match a variety of decorative styles.
• Lighter in weight than solid wood, which can simplify handling and shipping.
• Uniformity in production ensures consistency across multiple frames.

Uses in Framing

• Decorative picture frames for artwork, photographs, or certificates.
• Mass-produced frames for retail or commercial settings.
• Replicas of traditional or historical frame styles at a lower cost.

Advantages and Considerations

• Cost-Effective: Cheaper than carved wood while still providing a high-end appearance.
• Durable: Resistant to warping or splitting compared to some natural woods.
• Customization: Can be painted, stained, or gilded to match a specific design.
• Environmental Factors: Sensitive to extreme heat or prolonged moisture exposure, which may cause deformation.

Best Practices

• Inspect mouldings for uniformity and defects before finishing or framing.
• Use appropriate adhesives and fasteners when assembling corners to prevent separation over time.
• Pair with acid-free mats and backing for artwork preservation.
• Avoid exposure to high humidity or direct sunlight for long-term stability.
