Understanding Advanced Manufacturing Techniques
Romar Engineering has been at the forefront of Australian manufacturing for over 50 years, and we’ve seen – and adapted to – major changes in industry practices. To deliver robust manufacturing solutions today, we know that manufacturers need innovative technology, broad capability and agility.
At Romar, our world class team utilises advanced manufacturing techniques and materials to provide our scalable and globally-orientated manufacturing solutions. We have full capability in the development, prototyping, testing, manufacture and renewal of superior quality components and parts.
Industry 4.0 Manufacturing
Also known as the Fourth Industrial Revolution or The Internet of Things (IoT), Industry 4.0 fuses traditional manufacturing with digitalisation. It commonly takes the shape of industrial robotics, 3D printing, or system integration – the integration of data-collecting software into traditional machinery – to gain valuable data analytics. The information helps companies improve efficiency, quality and performance.
Custom senses gather process information, and we use the PLCs to store and analyse data such as CFD (computational fluid dynamics or mold flow analysis). By analysing the flow of material in the tool itself, it helps us create optimised injection molding tools.
System integration is possibility the least known but one of the most widely utilised Industry 4.0 advanced manufacturing techniques. At Romar, our molding system integration is the first stage of a wider strategy. We will next introduce it into our 3-axis and 5-axis CNC machines.
Additive manufacturing, or 3D printing, allows us to create custom and complex components to precise tolerances using high-tech materials. There is a high degree of variance in 3D capability and our elite DMG Mori Lasertec 65 3D 5-axis synchronous laser deposition, welding and milling machine has enhanced and unique features. It’s one of only three in commercial settings globally, and the only one of its type in the southern hemisphere.
Standard 3D printing adds layers of metal to build components. The Lasertec 65 is a hybrid printer, meaning it can add and subtract layers for optimum design flexibility. We can manufacture new components and repair or renew existing parts. Additionally, parts can be additively manufactured, finish machined and critical dimensions verified in a single set-up – which significantly simplifies the supply chain.
Additional features of our Lasertec 65 include capacity for higher deposition rates than a powder bed based system, the ability to produce complex 3D geometries up to 600mm diameter, and the capability to create metal blends or add metal to existing metal parts.
Sustainable manufacturing aims to minimise environmental impact by reducing energy consumption and using eco-friendly materials. Advanced manufacturing techniques like 3D printing, robotics and system integration may also be more sustainable.
Our Lasertec 65, for instance, needs no upfront tooling, reducing the part count for a streamlined and more sustainable supply chain. It also delivers a lower buy-to-fly ratio, resulting in a more sustainable approach to material procurement.
One method we employ is finite element analysis (FEA) – a complex mathematical model that allows us to determine stress concentrations, deflections and other issues prior to manufacture. We assess CAD drawings via specialised software to look for potential weaknesses, assess material functionality and optimise the design for manufacture. FEA allows us to minimise material usage for a more sustainable solution.
Expertise and Agility
Advanced manufacturing techniques are not just about technology. Innovation requires an expert team with the capability and agility to deliver diverse and flexible manufacturing solutions for clients in diverse industries.
At Romar, our team of engineers and materials specialists are leaders in their fields. Their broad expertise includes additive manufacturing, medical device manufacturing, micromolding, silicone and elastomers – and every stage of manufacture from initial analysis to materials selection, design for manufacture, commercial manufacture and logistics.
