Robots boost capacity at aluminium foundry business
Midlands precision aluminium diecaster JH Lavender has invested in a new robot cell in the wake of a raft of new long-term contracts from some of its major customers. A 1600 tonne automated diecasting cell featuring a 6-axis KUKA robot for unloading components has been added to a new 620m² diecasting hall at JH Lavender’s site in West Bromwich.
The company already uses four KUKA robots with three models deployed on its series of 750 tonne automated diecasting machines while the other is used to saw and rout a variety of parts in a separate finishing operation. A decision to make a further investment in automation was an important part of its ambitious expansion plans, which were commenced in 2009 at a time when many firms were streamlining their operations in the wake of the recession.
Buoyed by new contracts and the backing of its bank and regional business development agencies, JH Lavender embarked on the largest-ever single investment project in its 94-year history with the creation of the new diecasting hall. The purchase of the new 1600t cell also means it is now one of only 4 aluminium diecasters in the UK with machines in this high tonnage range.
Diecasting machine maker Colosio, who commissioned and installed the new 1600t cell, chose a KUKA KR150 foundry robot as it is specifically designed for challenging work places. It is not only triple coated in heat-reflecting paint, but also has a heat-resistant inline wrist.
The robot performs a number of tasks once it has extracted the component from the diecasting machine. It lifts the part to a checking station where a set of 6 proximity sensors verify it is in tact and then chills the component by immersing it in a tank of water. The final task involves depositing the component on to a chute where it is collected by an operator who trims off any excess aluminium in a hydraulic press.
“Automation is crucial and the use of robots means we not only achieve optimum process control, but also consistent repeatability. KUKA robots are very robust and flexible, making them well-suited to working in a foundry environment,” commented Anthony Evans, JH Lavender’s business development manager.
In response to rising demand for its services from customers in the automotive and construction machine industries in the UK, Europe and the Americas, the company is already planning to automate a number of other diecasting machines in the near future.
“JH Lavender’s commitment to investing in automation demonstrates how businesses can transform a range of production processes and gain significant competitive advantages,” said Richard Goodwin, one of KUKA’s UK robot sales specialists.
