Engineering/Mold Construction:

Legrom implements ideas in plastic, gives shape to your wishes and offers a broad range of knowledge regarding all materials and their properties.

The Legrom mold-construction specializes in extraordinary tool solutions for injection moulded parts.

Please, pay attention to the following details giving you an idea of the wide capability range offered by our mold construction and engineering:
 

CONFIGURING/DEVELOPMENT

Our development department and our partners are capable of exploiting a complete range of options, thanks to the utilization of the latest CAD technology.

We use the following systems:
» MegaCad 2D / 3D
» Catia V5 2D / 3D
» VISI-CAD/-CAM
We conduct finite element analysis, where we can depend on established partners with whom we cooperate via the data network. Moldflow is an injection molding analysis program which enables us to identify critical manufacturing and quality problems and develop suitable recommendations for solutions. Utilization of the latest interface software for data transfer also allows us to exchange drawings with partners using other CAD systems. Data formats: DWG, DXF, IGES, STEP, CATIA, SOLIDWORKS and others.

Uncompromising use of the data flow (CAD design data, CAM programming and CNC machining centers) enables direct exploitation of design data in mold production.

» Stereo-lithographic parts
» Laser-sintered parts
» Vacuum cast parts
» Milled plastic or aluminum parts
» Injection molded parts from test molds

Whether for exhibit purposes at trade fairs, exhibitions and training facilities, customer consulting service, personnel training or emphasizing the spatial or optical design - a model always attracts interest and awakens general attention. We utilize a variety of materials and employ common rapid prototyping processes to produce models and/or sample parts from test molds.

Mold perfection governs the quality of the final product.

Our mold and fixture construction division consists of:

» CAD workstations
» CAM workstations
» CNC milling machines
» CNC milling machine centers
» CNC cavity sinking EDM machines
» CNC wire EDM machine
» Cylindrical grinding machine
» Surface grinding machine with profile and crawling feed grinding capability
» Lathes
» Drilling machines

 
Our experienced and highly motivated team produces injection molds and transfer molds with dimensions up to 396 x 496 mm. Legrom mold construction division specializes in exceptional mold solutions for injection molding parts (e.g. realization of injection molds for the roller bearing industry with over 80 pushers and integrated forced ejection technology).

Special tool steel, coatings and a highly effective tempering system are required for the high performances polymers we employ (PEEK, PSU, PES, PPS). Fixtures are developed, constructed and tested for complete solutions. We communication closely with the mold design department to realize customer demands as rapidly and flexibly as possible. Constant quality control conducted by trained specialists ensures that the renowned Legrom quality is assured right from the initial production phases.
