Model Solution’s ProtoTool Process Simplifies and Accelerates The Development of Prototype Tooling

Model Solution (LRD: London) has launched its new ProtoTool program that significantly improves the process for developing prototype tooling. The ProtoTool process saves customer’s time and money in the initial tooling process, simplifies the modification process for fine-tuning designs, and gets products to market faster.
Using a two-part tooling system for injection molding, Model Solution builds a customized mold-core (containing the cavity, core, slide cores, lifters and ejector parts), while using a standard mold-base. Using electrical discharge machining (EDM) technology, Model Solution produces stronger steel mold-cores that last longer and generate parts with better visual quality. Steel tooling can be used throughout pre-production runs, and if necessary, material can easily be added during the design verification process. Adding material to aluminum molds is a significantly more difficult process, and can result in missed schedules and cost overruns.
Beyond tooling for injection molding, Model Solution utilizes the ProtoTool process to produce parts as diverse as flat metal stampings, wireforms, flat springs, belleville washers, and machined components – faster and better.
“ProtoTool provides the highest quality tooling at a lower cost and in less time. The robust steel mold-cores last much longer than aluminum molds typically used for tooling. This allows us to continue making parts throughout the sample iteration phase, until the part meets the design specifications and is ready to go to production tooling,” said Danny Sung, Director of Sales at Model Solution.
One of the major challenges in the ProtoTool process is determining the manufacturability of a new part through DFM. Model Solution works with the customer to make any needed design adjustments to overcome tooling limitations, such as part draft angles or undercuts that may require lifters to be built into the mold-core. Most times the DFM process identifies those design features that are of key importance and results in a better designed part. Additionally, the ProtoTool process identifies part designs that are not feasible for manufacturing and will result in complications in the future.
Model Solution starts with a Design for Manufacturability (DFM) review of the project, which outlines the tooling design and highlights part design changes that may be needed to overcome tooling limitations. A number of iterations may be required before the part design is finalized and approved. Model Solution then manufactures the prototype tooling in-house using its advanced computer-aided design (CAD), computer-aided manufacturing (CAM), machining, electrical discharge machining (EDM), finishing, assembly and inspection equipment.
Model Solution’s ProtoTool process enables the production of the finest, most accurate visual design models, fully functioning engineering prototypes, and master patterns.
