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.
