OL.UD.350.4500

Maximum productivity at minimal production costs

The double-sided inline PVC laminating machine OL.UD.350.4500 from WPR offers the maximum production output achievable with a foil lamination machine. It combines the advantages of inline profile wrapping with the outstanding features of a double-sided lamination machine.

What is double-sided profile lamination?
Double-sided lamination machines can foil two sides of a profile simultaneously. They are equipped with two complete lamination systems on the same machine base, allowing two decorative films to be applied to both sides of the profile in a single pass. This eliminates the need to reconfigure the machine and run the profile through again to laminate the second side, making the double-sided profile wrapping particularly efficient. With the same running metres, double-sided lamination machines achieve 100% more laminated metres, while additional material handling such as stacking and rearranging goods and reloading the machine is no longer necessary. Besides doubling the production output, they also offer significant savings in time, labour, and personnel costs.

Maximum flexibility in colour selection
Another advantage of double-sided PVC laminating machines is the ability to select colours during the ongoing lamination process. You can run decorative films of the same colour or produce two-tone window profiles without additional effort. So-called bicolour windows are highly trending, as they can be colour-coordinated with both the exterior façade of the house and the interior design. This offers endless colour combinations that can be realised in the ongoing double-sided lamination process without machine stoppage or reduction in working speed. Both machine sides can be equipped with a double film holder, allowing you to switch freely between film rolls or colours during production. If needed, lamination on one side can be suspended to produce single-sided laminated PVC profiles. Especially for high-demand standard profiles, it makes sense to process all orders for this profile with different colour and film combinations consecutively in one production run. This eliminates time-consuming retooling of the lamination machines.

Why inline lamination?
Inline profile lamination refers to the integration of profile wrapping directly into the extrusion line of PVC profiles. Normally, PVC profiles are extruded as endless bars and cut and stacked at the end of the production line, then transported to the warehouse. The profiles to be laminated are then retrieved from the warehouse according to orders, brought to the lamination department to be foiled, and finally returned to the final product warehouse.
In inline lamination, all additional material handling is eliminated, as the profile bars are already laminated during extrusion and can be taken directly to the final product warehouse after cutting and stacking. This means enormous savings in material handling, time, and especially personnel costs.

What are the technical advantages of inline lamination?
Besides significant cost savings, the inline lamination process offers technical advantages over offline lamination:

• Clean and warm profiles: In profile extrusion, constant temperatures and conditions prevail, so the profile rods enter the lamination machine already preheated. This results in a stable lamination process that requires less temperature input, saving energy. Additionally, the PVC profiles are cleaner than if they came from the warehouse into lamination, as no dust or dirt could accumulate.
• Constant working speed: Profile extrusion operates at constant speeds. While these speeds are significantly slower compared to offline lamination, extrusion lines run for extended periods, reducing the need for frequent machine retooling. This results in high productivity in laminated running metres.
• Autonomous lamination machines: By integrating into the extrusion process, the inline lamination machine automatically adjusts the working speed. Primer and adhesive application are controlled automatically by the machine. Automatic systems for process control continuously monitor all critical working temperatures. This eliminates the need for constant operator presence at the machine, as it sends acoustic signals in case of temperature deviations or, for example, when the film ends, prompting operator intervention. This saves personnel costs, as it’s unnecessary to run the machine continuously with 2–3 operators. If possible, the extrusion team can even take over control of the lamination machines.
• Reduced material waste: Inline lamination is a slow and easy-to-control process, resulting in high-quality laminated profiles. There’s less material waste due to faulty profile rods, eliminating the need for complex reworking of small batches and individual rods. Most material waste arises from production stops and restarts, where film, adhesive, and primer are typically wasted.

Double-Sided inline lamination for maximum productivity
The in-line profile wrapping machine OL.UD.350.4500 combines all the aforementioned advantages of inline lamination and double-sided foiling. It is particularly suitable for the film lamination of PVC window profiles. In this machine, the decorative film is applied to the profile from both above and below. This orientation usually corresponds to the alignment of the extrusion tools, allowing the machine to be integrated quickly and easily into existing extrusion lines.

Wrapping up
With the OL.UD.350.4500, you can foil two sides of a profile simultaneously, achieving higher efficiency and significant savings in time and labour. It also enables endless colour combinations during the ongoing production process without stopping the machine.
By integrating profile wrapping directly into the extrusion line, additional material handling and personnel costs are eliminated. The inline lamination process offers technical advantages such as constant working speeds, reduced material waste, and autonomous operation.
Investing in the OL.UD.350.4500 means double production output, maximum flexibility, and significant cost savings. You can produce cost-effectively and remain competitive in the market.
