Computer Assisted Designs, Thorough Testing, and 3D Rapid Prototypes Manufactured in Wisconsin

When you work with the CAD specialists at Retlaw Industries, you save time and money getting the OEM component you require. Our expert designers use the latest CAD/CAM modeling software to guarantee a tested design concept, valid prototypes, and the most accurate machining. Our designers employ a variety of simulation programs in our rigorous testing and machining process, including:

  • PTC Creo® Software – This essential product design software is used by all the plastic part designers and thermoplastic manufacturers here at Retlaw. Through it, we develop high quality 3D CAD modeling, schematic designs and technical illustrations of thermoplastic parts. Creo® design software is the premier software we use to create our composite plastic parts.  
  • Solidworks® – An essential piece of software to the Retlaw design process. Provides full solid model and 2D drawing creation and automates common tasks used in the design process to streamline workflow. Allows for advanced surfacing, parametric modeling, a variety of stress analyses and fluid flow simulations, and much more. Designs falling short in testing will never see one of our advanced cutting machines.
  • Mastercam® Mill X5 – A preferred software of CNC programmers. This CAM program grants the programmer flexibility to plan the cutting workflow and is capable of setting up dynamic milling motions to allow for speedy and smart roughing. Hybrid cutting capability further streamlines the process by combining two cutting techniques into a single tool path.
  • SOLIDWORKS Premium 3D – Helps avoid potentially costly defects in plastic molds before they are produced. Gives our designers the ability to simulate, fill, sink, shrink, predict warping, and perform surface stress tests.
  • 3D Rapid Prototyping – Retlaw will produce an accurate and refined prototype of your product, quickly turning the component in your head into one you can hold in your hands. Thanks to the latest in 3D printing technology, we are able to make your component a reality before it hits production.

Precision CNC Produces Tight Tolerances

The operators and programmers at Retlaw Industries take their craft to the next level, using the latest in CNC machining technology. Since the late 1970s, Retlaw’s CNC engineers have been on the forefront of milling technology, producing high-quality tool molds and meeting or exceeding their clients’ demands.

In keeping with this tradition, Retlaw’s Hartland, WI facility is in the process of phasing out hydraulic CNC machinery in favor of electric - improving energy efficiency and lowering operational costs, which ultimately means client savings. Using our efficient CNC machinery, we employ a variety of tooling techniques to meet our clients’ expectations, including:

  • Lathe Machining
  • 3-Axis CNC Milling
  • Wire EDM

Quality Graphite Templates make Precise Molds to Build Precision Plastics

Our tooling specialists use graphite electrode templates in the electrical discharge machining (EDM) process to create the desired negative shape. Wire EDM, or wire burning as it is occasionally known, is used to make precision cutout and shapes through steel plates up to 12 inches thick with extreme accuracy.
