FAQ

A surface layer is bonded to a core material, which is known as wrapping or profile coating. The core material can be made from various substances, including particleboard, MDF, solid wood, aluminium, plastic, plaster, or other materials. The type of adhesive used varies depending on the core material and the environmental conditions, such as moisture and temperature, in which the product will be used. There is an extensive range of foils, veneers, and laminates available for finishing the core material to achieve the desired appearance.

Wrapping has been used as a production technique since the mid-1970s. During the technology’s development phase, European producers began to see it as a gateway to creating solutions where solid wood was not optimal. Since then, technology and materials have evolved, and new uses and applications for the technology are constantly being identified. At Herrljunga, we launched our first wrapping line in 1981 and have since made significant improvements. Today, we are capable of handling a wide range of products, from small glazing beads to complex aluminium profiles, as well as broad wrapping panels exceeding 1200 mm in width.

The current state of technology means that it can now be highly profitable to wrap products, even in small series. In fact, for some customers we run series as short as 50 metres. The price per running metre quickly drops from a relatively high level at production runs in the tens of metres, becoming really attractive in production runs of a few hundred metres. As changing surface material is a relatively easy procedure, it is possible to bundle together several different types of moulding of the same profile to produce the number of running metres on which we calculate the price we charge. For example, imagine that for one profile you need 300 running metres of white foil, 100 running metres of black foil, and 100 running metres of oak veneer. Our offer is then calculated on the basis of 500 running metres of profile to be produced.

We manufacture wrapped components primarily for use in indoor environments. The vast majority of the products we manufacture are made using core materials of MDF, particleboard, or solid wood, and are wrapped with paper-based foils or veneers that are not suitable for outdoor use. Some solutions that utilise moisture-retaining cores, such as moisture-retaining MDF, aluminium or plastic, in combination with PU adhesives and plastic-based foils or laminates, can produce solutions that are well suited to environments where there is variation in moisture levels and temperature, which also means they are sometimes suitable for outdoor use.

The tooling is the cutting steel used in profile planers to create the customer's desired profile; these can be blanks or fixed tools depending on the application. Compared to plastic profiles or aluminium profiles, the tooling cost is very low. In most cases, we find combinations in our large tool bank to solve the customer's needs; otherwise, we produce customised tooling, which is charged as part of the product cost.

Veneer is real wood cut into very thin (0.3mm) layers. The veneer is glued together on a non-woven fabric (flies). A veneered profile allows access to the natural variation in colour and texture of the wood. Foils are made from paper or plastic material with printed decoration and can also be textured (relief printed). Foils are available in a variety of standard designs, but can also be tailored to your specific requirements.

No, your profile can be wrapped with a pre-painted or stained veneer. This can often be the most affordable solution, as it creates the desired profile with the required finish in one step.

Most of the foils we use are paper-based, but we also offer real wood veneers.
