Cold pressing is a common method used in skateboard manufacturing to shape and mold skateboard decks. It involves using hydraulic pressure and cold temperatures to compress layers of wood veneer together to form a strong and durable skateboard deck.
The process begins by stacking several thin layers of wood veneer on top of each other, typically made from maple or other hardwoods known for their strength. These layers are arranged with alternating grain orientations to enhance the deck's overall strength and flexibility.
Once the veneer layers are stacked, they are placed in a mold that has the desired skateboard shape. The mold consists of a concave shape and the dimensions of a typical skateboard deck. The deck shape may vary depending on the manufacturer's specifications or customer preferences.
Hydraulic pressure is then applied to the stacked veneer layers within the mold. This pressure can range from several hundred to several thousand pounds per square inch (psi). The pressure helps to compress and bind the layers of wood together, creating a solid structure.
To maintain consistency and improve the bonding process, cold temperatures are often employed during the pressing stage. Cold pressing typically involves cooling the mold and veneer stack to temperatures below room temperature. The cold temperature helps to reduce the curing time and allows for better adhesion between the layers.
The duration of the pressing process varies, but it typically takes several hours to ensure that the layers have fully bonded and the deck has taken its final shape. Once the pressing is complete, the deck is removed from the mold, excess material is trimmed, and it undergoes additional processes such as sanding, drilling, and finishing.
Cold pressing is valued for its ability to produce strong and consistent skateboard decks. The controlled pressure and cold temperatures help create a durable deck with the desired shape, concavity, and flexibility, making it suitable for skateboarding activities.
