Why we need Prototype?
Prototyping is an important step in the process of New Product Development. Prototypes can be inexpensively prepared by CNC machining stock shapes, by thermo-forming them from sheet stock, or simple injection molding tools can be made from soft steel or aluminum.
In addition to providing a three dimensional presentation of the design, a prototype allows:
- Subjecting the part to the chemical and mechanical environment it will endure in real life
- Accelerated testing for part life
- Checking compatibility with anticipated secondary assembly operations
How to protoype?
Prototype molds may be simple or complex, steel or aluminum. Injection molded prototypes from molds that have cooling channels can supply cycle time estimates and guidelines for commercial tooling. Determination of shrinkage factors, optimum gate sizes, vent locations and effect of mold temperature should also be established. Molded prototypes are preferred because flow orientation may influence performance. The latter is particularly important in glass-filled compositions.HS Mold excels in the construction of prototype tooling constructed from aluminum, P-20 or hard S-7 steel.
CNC machining Parts are mainly suitable for workpieces with complex shape, high precision or low quantity in the trial production of new products.Also, machining the shape can yield variable behavior because of random matching in areas subjected to stress.
When trying to determine the best path for your new project, it pays to consult an expert prototype mold builder based in China for advice on materials and construction methods to reduce costs, time and improve overall quality. Our team work with customers to identify specific needs and provide the right injection tooling for the volume and quality required. Though with low cost, we employ the same 3-D design concept as our production injection moulds. On your next prototype project contact experts from HS Mold.
