The main difference between injection mold and stamping mold is the forming principle, processing materials, mold structure, production efficiency, product accuracy and cost.
Forming principle: the injection mold by the heated melting plastic material from the injection molding machine high pressure injection into the mold cavity, after cooling and curing to form plastic products; while the stamping die is the use of press and mold on the plate, strip, pipe and profile, such as the application of external force, so as to produce plastic deformation or separation, so as to obtain the required shape and size of the workpiece.
Processing materials: Injection molds mainly process polymer materials such as plastics, while stamping molds usually process metal plates, such as steel plates and aluminum plates.
Mold structure: The structure of the injection mold is relatively complex, generally including the gating system, cooling system, ejection system, etc.; the structure of the stamping mold is relatively simple, and the common ones are single-process mold, composite mold and progressive mold.
Production efficiency: The production cycle of injection molds is long, especially for large and complex plastic products; the production efficiency of stamping molds is usually high, suitable for mass production.
Product accuracy: The accuracy of the injection mold is relatively low, especially for large-sized products; the stamping mold can achieve higher accuracy.
Cost: The cost of injection molds is generally high, especially complex injection molds; the cost of stamping molds is relatively low, especially simple stamping molds.
In summary, the choice of injection mold or stamping mold depends on the specific production needs and product characteristics. Injection molds are suitable for the production of plastic products, while stamping molds are more suitable for the mass production of metal products.
