Injection moulding machine for fast output of precision parts

The ROBOSHOT α-S450iA, which will be exhibited at Fakuma 2018 in Germany this October, is the seventh and largest CNC-controlled injection moulding model produced by FANUC. It has been designed to increase production capacity for manufacturers in the medical and pharmaceutical device markets. 

The α-S450iA has a clamping force of 4500kN, which ca be increased to 5000kN, allowing it to be used for both precision and large projected area components. Platen dimensions at 1300mm square, and tie bar spacing of 920mm, allows both large single component, or increased cavitation precision moulds to be accommodated. The 900mm opening stroke also allows customers to produce a variety of components using stack moulds.

The α-S450iA is also available in two injection unit sizes, to provide a broad range of screw sizes from Ø56mm to Ø100mm. This gives customers the scope and flexibility to manage a wide range of shot volumes up to 2,827cm³. 

The expansion of the machine range will also open new opportunities for FANUC in its traditional markets. For example, the α-S450iA can facilitate larger mouldings for external and internal trim parts used across the automotive industry, as well as enabling larger cavitation closure projects and containers requiring higher clamp tonnages for the packaging industry. It can also be used for general injection moulding applications which require larger surface areas and shot weight parts.  

“Complex geometries need high levels of precision, but as those precision capabilities increase, so too does the expectation for faster levels of output,” explains Andrew Armstrong, sales and marketing manager at FANUC UK. “That’s where the a-S450iA comes in. Manufacturers of precision parts, such as those used in the medical and pharmaceutical industries, can benefit from the same efficiency, control and accuracy as they would with other ROBOSHOT models. In addition, however, they also get the ability to use bigger or higher cavitation moulds for higher production capacity. “It’s quality and quantity in one, combined with FANUC’s precision and reliability.”

As well as using FANUC’s renowned CNC controls, the ROBOSHOT can be upgraded with a range of intelligent add-ons to protect mould system components and increase the lifespan of the machine. Precise Metering Control (PMC) functions, for example, prevent any uncontrolled volume flow from occurring between the end of the plasticising process and the decompression of the mould.
