Owen Mumford has invested in all-electric injection-moulding presses for its ‘Phase 5’ manufacturing facility at its Chipping Norton site. The all-electric moulding presses include five Fanuc Roboshot moulding machines and four Fanuc six-axis robots.

The five Roboshot S-2000 i250B injection-moulding machines are said to be ideal for the precise nature of medical device delivery systems where thin-wall, ultra-precision moulding is required.

Incorporating a high-power servomotor into the injection unit allows injection speeds of up to 1,000mm/sec to be achieved together with accurately monitored high clamping pressure.

Overall machine control is provided by Fanuc’s latest control technology based on its CNC control platform used across all Fanuc product lines.

The M-20iA robots have six axes flexibility to undertake load and unload tasks from the moulding machines together with second-operation assembly tasks if required.

The robots have a payload capacity of 20kg, providing adequate scope for future end-of-arm tooling requirements.

Key benefits of product application

  • High-quality and stable moulding is maintained by precise backflow monitoring and metering and the rigid construction of the machines.
  • Modestino Graziano, group operations director at Owen Mumford, said that the company’s past experience of Fanuc Roboshot all-electric injection-moulding machines means it knows that the total cost profile of electric machines is lower than that of hydraulic machines.
  • Graziano said: ‘Throughout the project, Fanuc has been happy to help, which is crucial to smooth the project implementation process. The integration of the hot runner systems to each machine was made straightforward by Fanuc’s support, combined with the flexible and open nature of the Fanuc control system.’

FANUC UK provides industrial automation solutions ranging from the supply of CNC controllers, robots, drilling machines, EDM and injection moulding machines through to the complete integration of factory automation systems.

Providing a single customer support portal for its three core businesses, FANUC comprises FA — CNC controllers, motors and drives; robotics — industrial robots and systems; robomachines — EDM, injection moulding and drilling machines.

CNC

FANUC’s FA business manufactures CNC controls, drive systems and laser systems. With a 65 per cent market share in the global CNC control sector, FANUC is the market leader. FANUC CNC is the controller of choice for the world’s leading machine tool manufacturers; continuously developing functionality sees FANUC CNC control being used in a wide range of applications — combining powerful control and high precision with unparalleled reliability.

FANUC servo drives and motors are well proven — aimed at the machine builder, they offer the widest range of high-performance compact designs.  The high availability and ease of maintenance together with world-class, energy-efficient designs make them the motors of choice for thousands of OEMs around the world.

Robotics 

FANUC’s robotics business manufactures the widest range of robots in the world for applications from micro-electronics assembly to the forging of precision aerofoils for jet engines — in industries as diverse as pharmaceutical and potato processing — and with maximum payloads from 1kg to 1,350kg. More than 280,000 FANUC robots are operating worldwide, with production currently geared to meet demands of 5,000 per month. FANUC robots are truly ‘out-of-the-box’ automation designed to be totally flexible and, with application-specific options, straightforward to integrate.

Robomachine

FANUC’s robomachine business manufactures Robodrill machining centres, Robocut EDM machines and Roboshot electric injection-moulding machines. Using FANUC components throughout, the robomachine business builds on the advanced technology, reliability, energy efficiency and innovation of its own controllers, drives and motors. With a focus on energy efficiency and high reliability, the robomachine business developed the first all-electric injection-moulding machines — Roboshot — changing the mould shop into a much cleaner and quieter environment.

Customer support

From initial sales contact with FANUC through the life of the product, FANUC provides one single contact point to make sure support is always at hand with up-to-date advice, genuine warranted parts and, whenever possible, obsolescence avoidance solutions that ensure the lifetime delivery of maximum efficiency.
