Molds & Dies
MOLDS & DIES – 3D MEASUREMENT APPLICATIONS
Molds are integral to the manufacturing process for cast components made of metal or plastic. A bad quality mold that is designed incorrectly or has a high wear level, can have substantial production consequences, which significantly increases the number of faulty products. 3D white light scanners are a fundamental part of molding companies’ daily operations in the areas of:
To maintain production reliability over the years by archiving 3D data for molds when the CAD design is missing or no longer accurate.
As production is carried out, molds are used repeatedly and thus lose their reliability. A bad quality die can have substantial consequences on production, so it is important that you area able to adjust the die and replace broken dies according to tolerances so as not to affect the geometry of the part.
Use the SIDIO 3D scanning system to digitize the original or modified mold and archive the data for future comparison or reverse engineering.
Storing a digital copy of the parts offers two advantages.
First, the digital copy can be used to perform future maintenance on a die. By comparing the die to the digital copy, you can identify eroded areas that need to be repaired.
Second, when the die has been manually changed, the digital copy can be used to quickly and properly include those changes in the original CAD files through reverse engineering.
As a result, you can improve the production process by adjusting dies and periodically controlling their status in order to avoid faulty parts production and subsequent customer penalties.
To produce a mold under tolerance.
Sometimes the mold design doesn’t fit and it needs to be adjusted in order to optimize the casting process. For example, when a gating system is not efficient enough and you have to create a new gate.
To obtain valid parts following the casting process, it is important that the mold is under tolerance. Therefore, you must be aware of the adjustments that have been made so you can correct the CAD file accordingly to make the mold match the design.
Using the SIDIO 3D scanning system allows you to digitize the original or modified mold in order to create a new reference/CAD file.
By scanning the modified mold, you can obtain the parts’ 3D shape more quickly, easily and accurately, thereby reducing the amount of time staff would have to spend to create a CAD file from scratch or adapt the existing reference file.
To reduce production downtime when repairing a used mold.
When a mold starts generating faulty parts, there are two different actions you can take: Replace the mold with a new one or try to maintain the existing mold by implementing modifications.
Producing a new mold is expensive and can cause production standstill resulting in considerable losses. Therefore, adding material to the used sections and machining it to return it to tolerance may be the quicker and cheaper solution. In this case, knowing where the stock material is located and what quantity needs to be removed is important.
Create a 3D scan of the forged part and use it to align the scan on the archive (CAD ) and then place it into production tooling (CAD). In this way, the CAM application can recognize the 3D scan as “stock material” and create CNC milling scripts.
Direct machining provides considerable savings in terms of both time and material used to produce each part.
To guarantee customers that the mold will produce parts and pieces that are within the required tolerance.
Faulty molds & dies may have critical effects on the production. Their reliability is essential for the manufacturing company to select and apply a specific process based on the mold characteristics. Without the assurance the mold is well manufactured, there is less guarantee that parts are under tolerance.
Our 3D white light scanners allow you to obtain complete surface information of the mold. With a nominal reference and measurements from the digitized information, you can analyze any deviations that occur between the design and the manufactured mold.
As a result, you can quickly detect invalid molds, identify and correct the processes responsible for producing the errors. Once the mold is homologated, you will be able to minimize iterations in the product development cycle reducing faulty parts number.
To guarantee gauges do not affect negatively the parts shape.
Repeated part production can lead to significant mold erosion that creates changes in the geometry of a workpiece.
Therefore, it is crucial to detect the moment at which mold erosion, as well as other wear and tear, causes a piece to fall outside of necessary tolerances.
Use SIDIO systems to monitor manufactured parts at certain stages of production by comparing the digitized copies of the manufactured parts to their CAD file. From this information, you can determine exactly when part geometries exceed their defined tolerances.
Thus, it is possible to not only detect when changes in mold geometry become too severe, but also to determine where on the mold those changes in geometry occur.
The severity of the erosion can be detected so that the right areas of the die can be repaired.
Additionally, identifying the die as faulty allows you to stop production of invalid pieces and carry out tool maintenance with minimal waste of time and material
