Mar 2015 – Fundamentals of reliable dewaxing

To ensure successful dewaxing, it is necessary to follow certain guidelines.

  • Main objective to avoid shell cracking is to melt the wax at the wax/mold interface to allow the wax to be absorbed into the prime coat and create space for the remainder to expand. The critical time is from the mold being removed from the shell room to being at pressure in the autoclave.
  • Keep this time to a minimum by having
    • A simple effective loading system
    • Fast reliable door operation with push button actuation to integrate with safety interlocks
    • Short simple steam transfer from boiler section to autoclave section.
    • Minimal restriction on steam entry and automatic air venting
  • Aim for time from cycle start to achieving 90 psi to be under 3 seconds
  • Control the rate of steam depressurisation
  • Use steam from autoclave to ‘force’ wax to a large container through steam heated pipework
  • Have clear push button operation and record basic system data through data collection or by network integration

The LBBC dewaxing Quicklock® Boilerclave® has been supplied to the industry for over 50 years and is used by most of the leading investment foundries in the world.

 

The removal of wax from molds is an important stage in the investment casting process that reduce yield if not performed correctly.

There are basically two generic methods for dewaxing – use of air i.e. flash fire or steam i.e. autoclave. Due to the unique heat transfer properties of steam – just put your hand over a boiling kettle with steam at only 21[...]

Feb 2015 – LBBC Technologies further expand process technology knowledge with KTP

LBBC Technologies’ Managing Director Howard Pickard, recently presented at a Manufacturing Advisory Service (MAS) and Leeds Manufacturing Forum event on how his company had been working with the University on a Knowledge Transfer Partnership (KTP), said

 

“Being a local SME, it is important that we explore the opportunities the University of Leeds can offer us, using its expertise and facilities to further our product innovations.

 

“We identified the KTP initiative – run by Innovate UK – as the most effective form of collaboration and are nearing the end of a highly successful two and a half-year programme.

 

“The associate has brought a lot of expertise to our business, expertise we couldn’t have afforded to bring in ourselves and this has resulted in the development of new coating technology that will ensure our products remain globally competitive.”

 

During the recent Manufacturing Advisory Service (MAS) and Leeds Manufacturing Forum-backed visit to the University of Leeds’ new £4.3m EPSRC National Facility for Innovative Robotic Systems a rallying call was made.  Yorkshire manufacturers were urged to embrace robotics and autonomous systems if they are going to make the most of new global opportunities and bring innovations to market.

 

More than 40 local manufacturers were given access all areas in a bid to showcase the opportunities for collaboration with Universities and how new technology – including one of the world’s largest multi-material 3D printers – can be used to develop new products, introduce new processes or build larger components.

Sept 2014 – LBBC moves into new £1.5m manufacturing facility with LEP support

Work on the new 15,000 sq ft facility in Stanningley, Leeds, was completed at the end of August, following an eight-month build period managed by Triton Construction. The new premises feature 10,000 sq ft of manufacturing space for assembly, testing and development, plus 5,000 sq ft of modern office space.

The £1.5 million investment has been supported by a £130,000 grant from the LEP’s business growth programme. Funded through the Government’s Regional Growth Fund, the business growth programme is designed to help businesses expand and create jobs. It offers grants of between £10,000 and £500,000 to SMEs to cover up to 20% of the cost of capital investment in new premises, fit outs and equipment.

LBBC Technologies is a division of the £8.5 million turnover LBBC Group. It is a world leader in the supply of autoclave systems and related engineering activities used in a range of high pressure applications and environments.

The company recently supplied equipment worth over £1 million to Rolls-Royce for its new blades casting facility in Rotherham, one of the most advanced investment casting foundries in the world. Other clients include BAE Systems, and over 70 per cent of the firm’s sales go to export markets in the US, Russia, China, Asia and Europe.

Sister division LBBC Beechwood focuses on sub-contract activities of machining, dished heads and fabrication for the domestic market. With specialist capability and approvals to undertake pressure vessel manufacture and fabrication for the USA and China, LBBC Beechwood is well placed to work with UK partners as a key supplier to these markets.

Roger Marsh, Chair of the Leeds City Region Enterprise Partnership said: “The Leeds City Region is a major centre within the UK for advanced engineering and the LEP is delighted to support this investment in new testing and development facilities, which will enable LBBC to continue as a global leader in its field.

“As the largest manufacturing centre in the country, the sector has a key role to play in driving above-trend growth and jobs as part of our strategy to develop the Leeds City Region as a powerhouse for the UK economy.”

The group currently employs a workforce of 70 and managing director Howard Pickard sees scope for further growth across both divisions of the group: “We’re aiming for £10 million turnover and there’s potential to go beyond that. In the process, we expect to increase the number and calibre of the people we employ.”

“The new facility for LBBC Technologies is critical to our strategy going forward, with the need for continuous investment in product development and testing to support highly specialised projects and maintain our position as global leaders in sectors such as investment casting. The new premises are now home to LBBC Technologies, providing space for our sister division LBBC Beechwood to expand into existing facilities on the site.”

LBBC, originating as the Leeds and Bradford Boiler Company Ltd is a long-established family-owned business and has been located at its current site in Stanningley, Leeds, since 1876. Howard Pickard and his brother Robert are the fifth generation of their family to run the business.

Cllr Keith Wakefield, Leader of Leeds City Council and Chair of the LEP’s investment panel said: “Manufacturing remains an important sector for the Leeds economy, employing around 30,000 people and punching well above it weight both in terms of output and productivity. The investment by LBBC and its plans for continued growth are excellent news for the company and its workforce.”

With support from the Leeds City Region Enterprise Partnership (LEP), a world-leading engineering firm based in Leeds has moved into new purpose-built manufacturing premises as part of a process of continuous investment that aims to push sales growth to £10 million and beyond.

Aug 2014 – LBBC to demonstrate new ceramic core leaching unit at ICI Equipment Show

As part of LBBC Technologies’ extensive R & D into the core leaching process, as presented in a paper at ICI 2013 by Howard Pickard, the company have developed a new ceramic core leaching model to extend the range of component and core geometry that can be efficiently leached. This unit now provides a solution for the commercial and medical sectors as well as low volume aerospace components.

The unit maintains the same basic processing system as has been proven on the many larger core leaching systems supplied to aerospace and IGT foundries throughout the world. As with all LBBC Technologies systems, the unit incorporates the highest levels of safety design. The new unit has demonstrated how ceramic cores, traditionally removed by other techniques in days, can be removed in hours in a safe and controlled environment.

LBBC who were founded in 1876 have invested in a new manufacturing and R & D facility at their Leeds site moving into the new facility at the end of July.

LBBC Technologies are exhibiting at ICI Equipment Show on 6th and 7th October 2014, in Covington, Kentucky, USA they will be in Booth 411 and 413 where they will be demonstrating their new core leaching unit.
