Laminating


Lamination is the technique of manufacturing a material in multiple layers so that the composite material achieves improved strength, stability, sound insulationappearance or other properties from the use of differing materials. A laminate is a permanently assembled object by heatpressurewelding, or adhesives.

Scales of production

One-off production

Labour and material costs are high, and a high level of design and manufacturing skills are needed. An example of one-off production would be a made-to-measure wedding dress.

Batch production

 Set quantities of a product are manufactured to order. Batch production requires a high level of design, pattern making and sampling skills. Materials are cost-effective and manufacturing costs are lower than one-off production.

Mass production

 industrial-scale manufacture of large quantities of products, usually on production line. Standardised production methods mean it is suitable for products that rarely need to be redesigned.

Finish

Depending on the finish, applying finish to timber keeps bugs from inhabiting it, keeps mildew from growing, keeps the wood from rotting as quickly, keeps the wood from splitting and drying out, and can keep the wood from splintering. A finish can also simply help to enhance the appearance of wood, and give it some colour, shininess, and smoothness.
