Defence companies vie for slice of $35 billion Australian frigate pie

Detailed planning for Australia’s Hunter Class Frigate Program is well underway as local companies vie for a slice of the $35 billion project. Nine anti-submarine warfare frigates will be built by ASC Shipbuilding at the Osborne Naval Shipyard in South Australia in what is being described as the largest surface ship project in Australia’s defence history. Construction of the first test blocks for the project will begin towards the end of this year with defence companies now being short-listed to carry out part of the work. Among them is Adelaide defence company AFL services, which has been down-selected for lucrative blast and paint work. AFL services was one of four Australian companies recently invited to tour global defence company BAE Systems’ world-class shipyards in Scotland to inspect painting processes used on the Type 26 Global Combat Ship. This is the reference ship design for Hunter class. “AFL Services has a proud history of working on defence projects, from land vehicles with BAE/Tenix toll defence, and components for Navantia to the Collins Class submarines,” General manager Adam Levi said. AFL Services now has more than 60 staff and winning a slice of the Frigate work would boost projections. ASC Shipbuilding won the head contract to provide the design and build framework of the nine anti-submarine warfare frigates that will be replacing the nation’s eight Anzac Class frigates. ASC Shipbuilding has become a subsidiary of BAE Systems throughout the build process before ownership is returned to the Commonwealth at the completion of the project. The two-year first building of five test blocks at the world-class digital shipyard in Osborne, Adelaide, is beginning in December this year with building of the first frigate expected to commence in 2022. “We appreciate that BAE System is embracing Australian industry content and helping small businesses reach their […]

Cheap, lookalike hydraulic cylinders give companies headaches

Global advanced industrial tools and services leader Enerpac says the NZ market is falling victim to cheap, lookalike hydraulic cylinders that are causing significant headaches when they fail in service. Enerpac New Zealand Hydraulic Specialist, Mr Neville Stuart, says that unlike genuine Enerpac branded gear, lookalike cylinders have not been engineered for rugged conditions and optimum durability and are not backed by Enerpac’s nationwide service and warranty commitments. “Everyone is conscious of working within budget limitations, so when a $2,500 cylinder is available for under $500, it looks like a good deal. But what costs are incurred when that cylinder breaks down prematurely?” asks Mr Stuart. “It can be ten times that amount in terms of lost time, and hundreds of times that amount in terms of safety liability if they fail.” “Not only does production grind to a halt, but you now have to seek a replacement part, because there is no warranty or service with lookalike brands,” he says. Enerpac equipment is used in major projects where safety, precision and uptime are critical, in industries such as building, construction, civil and mechanical engineering, electrical utilities, manufacturing, mining and exploration, metal processing, oil and gas and transport maintenance. “At the end of the day it’s a case of ‘cheap comes out expensive’ because when you add up all the bills, a lookalike cylinder ends up causing far more costs, downtime, delays and other problems.” Mr Stuart has been raising awareness of New Zealand’s lookalike cylinder problem for years but says that the lookalike brands are persistent because they know they can make a quick dollar, then disappear before things go wrong. “The lookalike cylinders are usually painted in an almost identical yellow, and catalogues can even use similar part coding systems, but at the end of the day, if […]

How viable is additive manufacturing?

~ The manufacturing and legal issues surrounding additive manufacturing ~ In 1984, Charles Hull invented the first 3D printer, which used stereolithography to build up a plastic product layer by layer. Over 35 years later, additive manufacturing (AM) is drastically altering a range of industries, from manufacturing to the medical sector. But what are the limitations of the technology? H In some applications, component manufacturing is shifting away from traditional subtractive machining methods and towards additive manufacturing techniques. The broadening of the applications of AM is causing manufacturers to assess the viability of using it in their own facilities. To do this, there are a few considerations to make before turning to 3D technology. Quality not quantity When moving from one manufacturing method to another, quality is a huge factor, particularly in highly regulated industries like aerospace and medical devices. In fact, quality has been one of the major hurdles to the widespread adoption of AM. One critical consideration is that quality and consistency must be the same machine to machine, regardless of location. Powder bed fusion is one of the most frequently used additive manufacturing methods and there is a possibility that it may introduce defects. However, if the process has a constant thermal gradient, it can prevent warping of the product, avoiding the introduction of defects due to incorrect temperatures. Another concern is that unsintered powder will degrade as a result of heat exposure and that this could impact quality, although regular changing of the powder can prevent this from becoming an issue. When investing in an AM system, manufacturers can overcome quality concerns by working with an experienced partner, who provides training and support on best practice. Those looking to invest in AM parts produced elsewhere should be mindful of their supplier’s approach to quality, to ensure […]

How 3D printing will transform design and engineering in the future

3D printing is now mainstream within schools and businesses because of its flexibility and ability to unleash users’ creativity. 3D printing offers a fast, inexpensive way to create prototypes, test ideas, and even manufacture components and products for commercial sale or use. This is triggering a change in the way organisations build and design their products. The results include cost reductions and the ability to improve products by applying design thinking principles such as latticing, part consolidation, and light weighting. On top of this, savings in supply-chains, product storage, and waste can be realised. 3D printing is maturing and changing quickly, and so too is the future of engineering and design. For example, the automotive industry can now benefit from much shorter lead times when using 3D printing, which allows for much faster development and testing of components. As 3D printing technology evolves, and new materials are developed, products that were previously not viable to print because of size, accuracy and material constraints become feasible. There has been a huge surge across the industry recently towards end-use parts. 3D printing’s ability to manufacture and combine parts has become more effective and is increasingly being integrated into an augmented manufacturing process. For example, dentistry companies can embed 3D printing into manufacturing process to create digitally engineered moulds for patients. 3D printing has made this process much more cost effective. Eric Holtsmark, general manager – strategy, transformation and technology, Konica Minolta Australia, said, “The future of product development can also be aided by 3D printing. The design of consumer goods such as electronics depends heavily on current market needs. As these needs change, 3D printing not only offers manufacturers a way to adapt quickly by shortening the design stage, but also the ability to produce cost-effective short production runs to test the […]

Datalogic AV500 industrial scanner enhances efficiency and accuracy

Datalogic’s new high-performance AV500™ 2D image-based reader enhances scanning efficiency and accuracy for high speed logistics conveyor applications, airport baggage handling systems, as well as static reading applications A new industrial scanner that extends the functionality of unattended data capture solutions is being introduced to Australasia and South East Asia by automatic data capture and process automation leader, Datalogic. The AV500 2D image-based reader incorporates several industry-leading features that allow the scanner to be used in a wider range of logistics, transport, distribution, retail and airport applications than were previously possible, without compromising on accuracy. Automated data capture systems radically advance the efficiency and reliability of inputting data, which used to be a time-consuming manual practice. Unattended data capture advances this further, with the automated processes and technology not requiring supervision from a person. “Advantages of unattended data capture solutions include improved accuracy and speed, improved cost-efficiency, reduced errors, faster turnaround times and reduced frustrations with paperwork or tedious tasks,” says Mr Mike Svetal, Senior Product Manager, Datalogic. “Datalogic’s new AV500 scanner enables unattended data capture to function to the highest levels of precision and efficiency, due to its industry-leading high-resolution 5 MP sensor, image acquisition at 32 frames per second, dynamic or adjustable focus, and multiple lens options,” he said. “The AV500 means that multiple reading attempts are no longer needed, because this powerful scanner covers a large area within a single image,” said Mr Svetal. “Additionally, the variable dynamic focus of the optical system increases the working depth of field of the camera, and its toggle mode provides variable focus for applications without the need for distance input, reducing overall system costs without sacrificing performance.” The rugged scanners come with IP65 rated metal enclosures, suitable for harsh environments with operating temperatures from 0 to 50 °C (32 to […]

Wefapress food grade plastics conform to global food and hygiene regulations

Plastics used in food preparation and processing areas need to conform to a special set of regulations, to ensure that all food they come in contact with remains safe to eat. To optimise food equipment hygiene compliance, engineering plastics leader Cut To Size Plastics is introducing the globally proven Wefapress Beck + Co. GmbH Food Secure Products (FSP) range to Australia and New Zealand. The FSP range has been certified to EU Regulation 10/2011, which is among the strictest standards in the world. EU Regulation 10/2011 covers areas such as starting substances, production aids, migration tests, declaration of conformity, traceability and good manufacturing practice. “Because these plastics meet all the requirements of the EU standards, which are some of the strictest globally, they set a very high standard locally for food safe materials,” said Mr Laurie Green, Managing Director, Cut To Size Plastics, which has been distributing plastics from leading German supplier, Wefapress, for decades. Work in the food industry is subject to strict hygiene standards that also apply in interaction with plastics. Plastics in this segment must be physiologically harmless in order to come in contact with food. This not only protects the health of the consumer, but also the composition of the food and its organoleptic properties. Wefapress has been a leader in food safety for decades. When the latest regulations came out, some of the items considered to be new standards of best-practice had been a matter of course for them for many years already. Key elements of Food Secure compliance Regulations around what materials can be used on food preparation surfaces and equipment centre around five key points: List of starting substances and production aids. Defines the materials to be used for production: Authorised are only the starting substances and production aids from the ‘Union List’ […]

Go-anywhere cylinders offer extraordinary power-to-weight

Global advanced industrial tools and services leader, Enerpac, is extending the versatility of its RAC-Series lightweight aluminium cylinder range, with new 10t and 15t models for smaller lifts requiring outstanding portability and power-to-weight ratios. The cylinders, with strokes from 50-250mm, weigh from just 1.3-2.0kg for the new 10-ton models and 1.9-2.9kg for the new 15-ton models, through to a maximum of 41.3 kg for the range-topping 150-ton models. “The new 10t and 15t models, which further extend the range, are particularly useful for maintenance tasks, and in situations where they need to be moved from job to job,” says Enerpac Asia-Pacific Marketing Manager, Mr Tony Cooper. The RAC-Series has been proven globally for years on lifts between 20 and 150 tonnes, where it provides the same lifting performance and safety in half the weight of equivalent steel hydraulic cylinders. Frequently used in workshops, fabrication and manufacturing applications, Enerpac’s range of RAC single-acting, spring return aluminium cylinders are one of the most widely used ranges in Australasia. “Cylinders often need to be carried for field maintenance, elevated platform work, up stairs or across processing plants. The light weight and outstanding portability of the RAC-Series cylinders are highly valuable in these situations, especially on remote sites, where they may need to be carried in by air or 4wd,” says Mr Cooper. The aluminium versions are also perfect for mounting on machines or applications where the weight of the hydraulic components is important. Because of their weight, aluminium hydraulic components can be more easily moved or removed for maintenance and repair. Their non-magnetic properties can also be useful in uses around high technology, equipment and magnetically or electronically sensitive instruments and applications in resources, processing and exploration. “Additionally, because it is non-corrosive by design, aluminium has always been a good material for use […]
