Getting smart about wood manufacturing!

The companies innovating and adapting for a changing industry

A commitment to new technologies for productivity and safety

Manufacturing company Timberlink has continually optimised its processes and looked to future industry trends at its Bell Bay, Tasmania and Tarpeena, South Australia sites. Both premises have received major upgrades in the past few years. The company has invested AU$90 million into the Tarpeena site, leading to the installation of a new stacker and edger, complete with leading-edge technology, as well as additional contraflow and batch kilns for more effective timber drying.

The Tarpeena green mill has installed a second sawline alongside the existing sawline, with state-of-the-art mechanical equipment including a bandsaw complete with thinner blade for less sawdust per cut, and a shape sawing gangsaw, which allows for maximum log recovery thanks to its ability to follow the compound curves in the cant (essentially a portion of log sawed on all four sides).

The improved technology of the new saw line can optimise for individual logs, and allows for better control of the line itself, including speeds optimised for throughput and more precise scanning of materials.

Tarpeena will also be home to a new cross laminated timber (CLT) and glue laminated timber (GLT) plant, scheduled to open in 2023. While CLT and GLT are not yet widely used by the Australian construction industry, research suggests this will be a rapidly growing market in the near future.

Timberlink Technical and Sustainability General Manager Trevor Innes commented, “We think there’s a real sweet spot for CLT in mid-rise construction, and there’s going to be a good market for projects in multi-residential and student housing. Buildings that are currently being constructed using steel and concrete are a natural home for this product. There are many benefits from building with CLT… it’s quicker to go up and makes for a safer and quieter worksite.”

Meanwhile Bowen-owned Timbertruss is leading the way in prefabrication, thanks to its automated production lines. As part of its processes, pre-production plans are sent to the factory floor, where automated machines select and place them on a conveyer for cutting, with sensors ensuring they remain on track. This means a human only needs to touch the timber once during the prefabrication process, creating a safer workplace.

Simultaneously, production processes and schedules at Timbertruss are centrally controlled with Mitek software to improve efficiency and minimise waste. This software can be used in the production of a wide range of products including roof trusses, wall frames, posi struts and flooring cassettes. The technology is sophisticated enough to allow complex structures to be built to exact specifications.

And while Timbertruss can already build commissioned structures at their premises in Geelong, it is moving further towards on-site installation.

A focus on environmental outcomesThere are also plans by Timberlink to build a biocomposite plant at Bell Bay. This plant will use the principles of upcycling to create a line of wood plastic composite products, like decking and screening. The products will be made from 55 per cent wood fibre sourced from plantation mill residues, and 45 per cent recycled polyethene, which will be sourced locally in Tasmania from a combination of high-density polyethylene (HDPE) post-consumer milk bottles and post-industrial waste.
