What is a Master Model?
Master model – this is an improved prototype of the product that is used for the subsequent manufacture of the injection mold. The requirements for the quality of the casting master model are quite high, because exactly it determines what will be the entire subsequent circulation.
Therefore, if you need to make a master model, the best solution would be to turn to professionals who use the right materials and accurate methods of making master models for casting.
What determines the price of creating a master model?
The cost of making a master model depends on following factors :
- complexity of execution;
- the number of parts.
METHODS OF MANUFACTURING MASTER MODELS FOR CASTING
3D milling involves creating a master model on a CNC milling machine. On modern CNC machines, you can make a master model of any complexity and configuration. It is also possible to choose the material from which the master model will be made – plastic, metal, wood.
You can also make a master model using 3D printing. To create a master model, most often they resort to the methods layered build-up – stereolithography, selective laser sintering of powders, layer-by-layer 3D printing with molten polymer filament, inkjet modeling.
Often are used such materials like: ABS filaments, PLA, PVA plastic and polymer powder. The variety of 3D printers, materials and technologies determines the widespread use of 3D printing in the field of making master models.
STAGES OF MANUFACTURING THE MASTER MODEL
Creation of a 3D model of a product
Regardless of the chosen method of creating the master model, the first stage is creating a virtual copy of it in 3D. For this, an experienced specialist is involved – a 3D-modeler, who will build a model with exact dimensions. Building 3D models possibly by photograph, verbal description or drawings.
The choice of material and method of making a master model
Depending on the purpose of the product and quality requirements, one of the materials is selected: plastic, wood, metal or others … Next, the optimal manufacturing method is selected: 3D printing or 3D milling.
3D printing or 3D milling
After carrying out the preparatory work, the process of making the master model starts directly. Depending on the size and complexity of the item, the process can take from several hours to several days.
Master model processing
Because the requirements for the quality of the master model are quite high, after production, it needs to be finalized. Namely: polish the surface, carry out assembly, eliminate defects if any, etc.
Where to order a master model?
Creating a master casting model requires experienced professionals and expensive equipment. All this you will find in by KLONA … Our specialists take over the solution of the problem, and will also advise on the further manufacture of products.
