VIETNAM CORE VENEER FACTORY FOR EXPORT
I. What is veneer?
Core veneer or veneer is a specific type of veneer used in the manufacture of plywood or laminated wood products. It refers to the inner layers of veneer that form the structural core.
The most common and abundant types of wood used to produced plywood in Vietnam is Eucalyptus, Acacia and Rubber. These trees easily grow in Vietnam as it can be well adapted to the climate in Vietnam and take only 5-7 years to be harvested on average. These hardwoods have many outstanding features for the production of plywood because the wood holds nails, screws, and glues well, is easy to be colored, sanded and polished to a great finish. Wood can be easily cut with both hand tools and machines. Furthermore, The ability to resist termites and bear strong impacts of wood is noticeable.
II. Technical specifications of core veneer plywood
+ Thickness: Its thinness is various based on the using purpose or customers’ orders. But it still makes sure flexibility and affordability. The normal thickness from 1.7 to 2mm, moisture under 20% drying or un 14% drying. Air-drying and forced-drying are two popular veneer drying methods.
Both methods create the highest quality veneer sheets for plywood production.
Vietnamese core veneer plywood is divided into three grades: A, B, and C. These grades suit plywood manufacturing purposes from high grade to low grade.
With high plywood standards with high quality, core veneer with Grade A: no rough, no mold, not tear at the head, not detects in the side would be very suitable.
II. The manufacture of veneer plywood
Log Selection and Preparation:
Species Selection: The type of wood dictates the final appearance and properties of the veneer. Moreover, hardwoods are popular because of their beauty and durability.
Log Preparation: Makers debark logs and carefully inspect for defects. In this process, any knots, cracks, or other imperfections will affect the quality of the final veneer. Then, they cut logs into blocks or bolts of the appropriate size for the chosen veneer-cutting method.
Veneer Cutting:
Rotary cutting (most common): The log is mounted on a lathe and rotated over a very sharp knife. This creates a long, continuous thin board.
Sliced Veneer: A block of wood is placed on a large, sharp knife and thin slices are cut sequentially. This preserves the natural wood grain pattern more precisely than rotary cutting, creating a more uniform appearance.
Half-round Slicing: A variation of slicing where a log is cut into half, and then sliced from the flat face.
Quartersawn Veneer: Logs are quartersawn before slicing or rotary cutting. Consequently, this results in a more uniform, straight grain pattern, and reduces the likelihood of warping.
Plain Slicing: Also known as flat slicing, this produces a veneer sheet from a flat surface of the wood block, and the grain pattern will vary from slice to slice.
Veneer Drying:
Moisture Control: Freshly cut veneer contains a high moisture content. So, it’s crucial to dry the veneer carefully to prevent warping, shrinkage, and cracking. This is often done in climate-controlled kilns.
