HARDWOOD PLYWOOD

HARDWOOD PLYWOOD CORE TYPES

VENEER CORE

All inner plies of wood veneer.
The hardwood plywood family of products includes panel products constructed with core material made from: veneer (softwood or hardwood, which may be of a different species than the panel face), lumber, medium density fiberboard (MDF), particleboard, other composite panels, or any combination of these core materials. Panels made with the various core types may differ from one another with respect to certain properties such as flatness, dimensional stability, screwholding ability, bending strength, and visual edge quality. The relative importance of specific properties in a particular application of the product help determine the appropriate core type that should be used. Be sure to discuss your product needs with your AWI representative so that they can suggest an appropriate panel for your particular use.

Thickness:

5/16” or less .......... 3-PLY 3/8” ........................ 5-PLY 1/2” TO 5/8” ........... 7-PLY 3/4” & Over ............ 7-PLY Min

Benefit:

Best screwhold power

COMPOSITE CORE

Consists of wood veneer inner plies with MDF or MPX.

Thickness:

1/2” to 3/4”

Benefit:

Lightweight. Strong. No core telegraphing. Ideal for overlaying of veneers, high pressure laminates and miscellaneus gluable papers and foils.

SOFTWOOD VENEER cores are light and strong

but do not typically yield a panel as flat and smooth as composite cores like particleboard or MDF. Using a two step, or “blank” process can significantly improve veneer core panels’ flatness.

MEDIUM DENSITY FIBERBOARD, (MDF) is flat

and smooth with good thickness tolerances. It machines well, but wears machine tooling and is quite heavy. Screw holding strength is less than veneer core.

PARTICLEBOARD CORE

Industrial Grade.

Thickness:

1/2” to 1-1/4”

PARTICLEBOARD is the low cost core of

choice. It is about the same weight as MDF, but does not machine as well and has poor screw holding capacity. Particleboard is flat and smooth, and has good thickness tolerances.

Benefit:

No core telegraphing. Least expensive.

MDF CORE

Medium Density Fiberboard
Specialty Cores include many variations within the above core types, as well as hybrids and non wood based panel products that are coming into commercial use.

Thickness:

5.2mm to 1-1/4”

Benefit:

Most stable. No core telegraphing. Uniform density. Superior machinability.

ANSI Plywood GRADING STANDARDS & DESCRIPTIONS

Where excellent appearance is very important as in cabinets and furniture.
Provide sound surfaces with all openings in the veneer repaired except for vertical worm holes not larger than 1/16.”

Where the natural characteristics and appearance of the species are desirable.

Some open defects. Repaired splits, joints, bark pockets, laps and knotholes can achieve a sound surface if specified by the buyer.

Provide sound surfaces but allow unlimited

color variation. Repairs in increasing size ranges allowed respectively from C to D. Applications- where surface will be hidden or a more natural appearance is desired.
Some open defects. Knotholes up to 4” in diameter are permitted. Open splits and joints limited by width and length.

VENEER CUTTING/SLICING CHARACTERISTICS

ROTARY CUT

SAMPLE SAMPLE SAMPLE

Rotary veneer is produced by centering the log in a lathe and turning it against a broad cutting knife which is set into the log at a slight angle. Rotary cut veneer can be sufficiently wide to provide full sheet (one piece) faces. Follows annual growth rings creating a bold variegated grain.

KniFe

PLAIN SLICED (FLAT CUT)

CUTTING DIAGRAM

Plain sliced veneer is veneer sliced parallel to the center of the log to achieve flat-cut veneer. The cathedrals are formed by the inner most annual growth rings as the veneer is cut through the flitch. Creates a prominent variegated grain.

KniFe

QUARTER SLICED

CUTTING DIAGRAM

Quarter slicing achieves a straight grain appearance by slicing perpendicular to the annual growth rings. This method creates a “striped” effect. Depending on the species, grain may be quite straight.

KniFe

RIFT CUT

CUTTING DIAGRAM

Rift-cut veneer is produced from the various species of oak. Oak has medullary ray cells which radiate from the center of the log like the curved spokes of a wheel. This straight grain cut is at a slight angle to the medullary rays in oak to minimize ray fleck (flake). Used on oak species, this method avoids the prominent “flake figure” of medullary rays that quarter slicing causes.

HARDWOOD PLYWOOD VENEER MATCHING

AWI offers a wide selection of veneer patterns and matches. Edge alignment by the following methods can create limitless and unique visual effects.

BOOK MATCHING

Alternating pieces of veneer from a flitch are turned over, so that adjacent leaves are “opened” as two pages in a book.
Veneer joints match, creating a symmetrical pattern. Yields maximum continuity of grain. Prominent characteristics will ascend or descend across the match. Tight and loose side faces alternate, which can yield a noticeable color variation. Proper finishing techniques may minimize this effect.

SLIP MATCHING

Adjoining leaves are slipped out in sequence, with all the same-face sides being exposed. The joint may not be noticeable if grain is straight.
Figure repeats but grain does not match at joints. Produces a uniform color because all faces have a similar light reflection. If grain is not exactly vertical, vertical slant may appear

PLEASING MATCH

Veneers are matched by color similarity, not necessarily grain characteristics.
Since no sharp color contrasts can appear at the joints, an effect between book and slip matched and random matched is achieved.

RANDOM OR MISMATCH DESCRIPTION

VISUAL EFFEC T

mismatched or planked effect. The components may be of different width within the panel face. ment of the leaves from one or more flitches. Usually done with lower grade veneers allowing knots, stains and other natural characteristics.
