Concept and Design

1. A working prototype is created using CAD technology.
2. The designer electronically creates an exact engineering model of the parts involved in the project in 3-D employing various colors, textures and environments.
3. Where necessary, accurate prototypes are created using advanced rapid prototype modeling techniques such as RP, STL, SLA [Stereolithography modeling techniques] or Laser Based Metal Deposition [SLS] to anticipate and identify potential appearance or structural problems.
4. Using the latest 3-D design software, a mold design is created and reviewed with you, the customer. With our cutting edge technology we are able to meet all of your requirements for single or multiple molds, in virtually any size or shape.

Planning and Production

1. Generate a physical working prototype via the CAD system, CNC machine or a handmade model constructed by an L&Z craftsman.
2. A flow analysis and/or FEA can be performed by the L&Z team to predetermine the most efficient gating and to determine the feasibility and workability of your design.
3. Once you are completely satisfied with the outcome, the actual design detailing and manufacturing begin. The finest materials are ordered and a production schedule is developed.
4. A combination of CNC and EDM processes are used to create geometries with any degree of complexity.
