Sash Window Workshop have just commissioned a new turn-key finishing plant for assembled windows from Schuberts.

Along with the their Dutch working partners, LTI BV NL, Schuberts have installed a new custom built overhead track conveyor system, complete with trolleys and both 800mm and 2000mm flight carrier bars. This means that small window frames and sashes can be hung as multiples and large single window frames, up to 4m wide can be hung as singles.

A new large spray booth, fitted with double layer extraction filter, is complimented with an air return plenum. This plenum takes up to 80% of the extracted air, filters it to remove any particulate and reintroduces it back into the spray shop.

An automatic lift station means that a single operator can load/unload heavy awkward items directly on the conveyor line.

Twin automatic humidification units with hydrostats are installed to control and regulate the moisture content of the spray shop air. This improves quality, aids the drying process and means the wood is under less stress when coated and cured.

The drying of the waterbased based paints is carried out with air movement from variable speed fan sets in combination with long wave gas catalytic infra red drying technology.
The double buffer drying zone is fitted with twin automatic pushers and is key to making this new installation run smoothly, to eliminate the traditional bottle neck of drying exterior paints and gives the customer total repeatability and consistency of finish.

An audible alarm and sensor system allows the operators to know when the windows are dried and ready to remove from the twin buffers lines.

Founded in 1987 by directors with a wealth of experience in the kitchen and timber moulding industry, Multiwood Products Ltd has developed into one of the leading specialist kitchen door and accessories suppliers in the United Kingdom.

Steady growth over the last 3 years has seen the volume of painted kitchen doors and components increase rapidly. Multiwood faced a situation where speed of delivery, quality and range of colours offered to customers, became of paramount importance.

To such end, a decision was made to bring their spray finishing in-house and contact was made with Schuberts. Various tests and site visits made, a suitable system was decided upon, encompassing each of the key areas of finishing:-

• Sanding/denibbing process and the collection of fine dust.
• Spraying in a clean, safe environment.
• Flash-off of solvent based paints.
• Rapid curing of solvent PU and AC paints and lacquers without affecting the substrates.
• Safe intermediate storage of paints and lacquers with the ability to mix custom colours and tints.

The spray shop is 7.0m wide x 8.0m deep, allowing plenty of space inside for racks and up to 3 sprayers to work independently of each other. Input air is filtered prior to entry into the spray shop to give a clean environment in which to spray.
Lighting is to 1000 lux levels and uses bright white flicker free sets.
Andreae HE filter ensures no particulate or overspray escapes through the booth.
Quiet running ATEX fans ensure a high extract rate, but a quiet installation.

After spraying, the dedicated flash-off zone allows the solvent vapour to vent off under ambient conditions and for the paint to flow out correctly.

The Schubox gas catalytic infrared drying system accepts product from the flash-off and after 20-30mins the racks full of Multiwood’s production, are ready for either de-nibbing or packing and despatch.

The Sandbox down draught tables are designed to take fine dust, filter the air and return it into the workshop clean. They are specifically designed for pre-sanding and intercoat denibbing and are fitted with an ATEX centrifugal motor.

A separate paint kitchen allows the safe intermediate storage of paints and lacquers. The bunded floor means that any spills are captured, the ATEX heater keeps the paint at the correct temperature and the separate extraction ensures no build-up of vapours.

Doug Allan of Multiwood says:- “The whole process, from initial enquiry to installation and commissioning of the completed system was conducted efficiently, on schedule and in a very short time.
Schuberts were available to deal with any queries we had regarding processes, materials and regulations, both up to and after completion and continue to do so.
This has been a major benefit and has ensured that we are producing a high quality product from day one.”

Dresser Mouldings have been established as a company for over 30 years. They have a wealth of experience and knowledge in the timber mouldings industry and have recently made significant investments within their finishing facility in response to customer requirements and ever more discerning clientele.

Operating from a 52,000ft² factory, Dresser Mouldings knew that the only way to grow the business was through differentiation, cutting edge technology and top quality production systems.
Back in Spring 2014, Dresser engaged with Schuberts, one of the UK’s leading manufacturers and suppliers of turnkey finishing systems, in a modernisation project for their spray finishing requirements.
After discussions and exhaustive live tests, an order was placed for a new Schubert profile finishing line.

The new finishing line is special in many ways; It allows hand feeding of product up to 300mm wide and 4200mm long. The spray machine is fitted with 2 separate spray circuits which allows a quick colour change. The line is able to deal with MDF, softwood, hardwood and exterior timber cladding products. In accordance with Dresser’s environmental policy, the new automatic coatings line is designed to run exclusively with waterbased paint and clear lacquer top coats.

Specially fitted with anthropomorphic arms, the spray machine is able to coat all 4 sides in one pass and with special outfeed roller conveyors, means no marking on the underside of the products.
The machine also comes with a special Teflon-coated pull-out internal trolley system on wheels to allow easy access to key parts and easy cleaning of overspray tubs and gun systems.

The sanding machine is fitted with 4 x Flex-Trim brush sanding heads where quality is paramount. There are many cheaper copies of Flex-Trim on the market but where quality matters most, there is no substitute. The sanding machine will not only pre-sand but also de-nibb after the first coat has been cured in the hot air oven system.

A temperature resistant Kevlar mesh infeed conveyor, before the spray machine, allows pre-heating modules to be incorporated, aiding rapid drying and promoting adhesion of certain waterbased coatings.

Special bi-conical outfeed rollers after the spray machine allow the processing of 4-sided wet product (where necessary) without marking on the underside. Finally a cross-transfer conveyor and hot air drying oven complete the system.

The line is more than capable of running up to 60m/min, but normally will run at 40m/min to give the best quality finish and to give the operators time to check the quality of each piece produced.

Mark Schubert says that “Dresser Mouldings have been a pleasure to work with from start to finish. They had a clear objective with the new spray facility and saw a clear gap in the market for high quality contract finishing across the UK. They were fantastic onsite and helped our engineering team install the new finishing facility within a working week. I am convinced that Dresser will find many new customers and be able to offer the UK timber market with an unrivalled level of service and quality for sprayed wooden products.”

Bill Gunn of Dresser Mouldings says “”Having exhausted the market looking for the right coating/spray applicator, the name of Schuberts kept coming to the top of our list.
We came away knowing we had found the right machinery and working partners in Schuberts.
Since the installation, we have been delighted by the professional and hands-on approach given by Schubert engineers and staff.
Dresser Mouldings were already a market leader in external water based coatings, however we lacked the ability to compete on internal water based lacquered coatings. Having now purchased the spray-line, it has transformed the company’s ability to offer both internal & external water based stains and lacquers”.
