Borg Manufacturing, an Australian producer of melamine-laminated boards, has ordered a new particleboard plant for its Oberon location in New South Wales.
Siempelkamp will supply a Generation 8-ContiRoll® (pressing format 8’ x 40.4 m, designed for an output of 1,500 m³/day). In this plant, two important technological core competences will be realised: for one the almost isobaric pressure distribution in the press and secondly the latest forming technology, presently representing the latest benchmark with respect to raw material consumption. This is achieved by an optimised material feed into the dosing bins and by two field-proven Eco-Formers, which are wind formers for producing the surface layers. The mat former system is completed with two CageFormers for producing the core layers; the formers are equipped with modules designed to adjust the weight-per-unit area of the mat. The interplay of these components enables a high forming precision and – along with the almost isobaric pressure distribution in the ContiRoll® – ensures an especially material- and cost-efficient particleboard production.
Retrofitting concept for an existing MDF-plant
At its Oberon location Borg is also investing in a retrofitting concept for an MDF-plant made by Siempelkamp. The upgrade comprises the installation of a completely flexible press infeed, a booster infeed hot platen, the installation of pressure compensation plates and the updating of the hydraulic system by adding a track of cylinders in the calibration section of the press. Along with the upgrade of the plant’s existing electrical system Borg Manufacturing Pty. Ltd. will benefit from increasing the plant’s output and at the same time reducing its raw material input.
A revision of the Ecopilot system is also part of the retrofitting concept. The existing concept will be provided with a total of eight tracks. The Ecopilot measures the board thickness at the press discharge over the board width comparing it with the set thickness. Any deviations can be compensated by controlled adjustment of the specific pressure within the calibration zone. The hydraulic system will be modified accordingly to individually adjustable cylinders.
