LBC offers the generative manufacturing of metal parts since 2004 as a service. Therefore LBC is one of the pioneers using this technology, especially in mould and diecasting applications. At the beginning we used the Trumaform LF 250 from TRUMPF.Since 2006 LBC is using the M270 from EOS.

engineering:
LBC is now commercially introducing a professionally engineered approach. The focus of this approach is analyzing new or existing moulds, reviewing the thermal efficiency, then optimize the design, resulting in the manufacture of Tailored conformal cavity cooling.
As experts in the lasergenerating manufacturing processes as well as our strength in developing and designing injection moulding tools LBC can offer you the opportunity to see what can do for your projects.For the best part quality and most efficient production, should be your first choice.
is the LBC brand for individual, customer specific solutions with conformal cooling and the manufacturing of lasergenerated mould inserts.

The technology Lasergenerating is offered by LBC as services. Since 2004 we were able to establish a hugh know-how. This knowledge is the base to realize customer wise tasks. Especially for new customers our detailed helpdesk is the needed support to erase the respect or fear regarding this new technology In an open discussion about all facts, the customer receives all background information he needs. This is the base for a good, future cooperation and the key for our success.

Complex mould require an extensive design to realize a perfect cooling.This design is based on fundamental know-how of the designer. So it was possible to provide this channel system.8 channels with Ø 3 mm and nearly identical length branch out of a 10 mm input. This guaranties identical flow in all channels.

The simulation of the expectable cycle time reduction is no manageable with any simulation software, because of the complexity of the conformal cooling systems caused by Lasergenerating. As simulation is the key to check on the efficiency of cooled inserts, LBC offers this simulation as a service. So the customer's purchasing department receives facts for their decision.

The simulation of a conformal cooling is done together with a flow analysis. Using the software LBC has a tool, to implement the total design of conformal cooling channels.
Therefore we need the following
article as 3D CAD data,
injection points,
form of the injection (e.g. hot runner),
plastics with data sheet,
process parameters injection
CAD data of the conventional cooling,
cooling data, flow volume, pressure, number of closed loops, temperatures etc.

In 2004 the acceptance of the lasergenerating was more or less ZERO. Nearly no mould maker wanted to believe in this new technology. A lot of question had to be answered and it was a hugh challenge to get the first orders.
Nearly no mould maker wanted to be first!
They did not accept the surface roughness and could not believe that the material property will fit to their needs.
Detecting the outside zero point with a touch probe was not as easy as with today's surfaces, built on a M270.

Limits:The volume rate is still limited
The maximum size of generatable inserts is limited
Will the channels get blocked?
Is the material property good enough?
What is the lifetime of such an insert?
Will the higher costs be paid by the injection moulder, who has the benefit?

Still no content of teaching at professional schools

LBC’s wishes for the next generation of M-series are:
The volume rate should be improved as much as possible
More different sizes of the building chamber
This machine has to be designed for mass production issues
Costs down, especially for spare parts and service

Market:
Having machines with highest productivity the market would be enormous.
Starting with the M280 we will able to compete against several other solutions of conformal cooling as:
soldered inserts
diffusion welding
hugher and longer inserts will be manageable
New application will follow step by step!
