Introduction to Injection Molding
Injection molding is one of the most widely used methods for plastic parts manufacturing. The process involves heating and melting thermoplastic material, then injecting it under high pressure into a mold cavity. Once cooled and solidified, the part is ejected, resulting in a highly efficient and repeatable production cycle.
Key Advantages:
-
High Efficiency: Ideal for mass production, capable of producing a large number of components in a short period.
-
High Precision: When combined with high-quality precision molds, it ensures dimensional consistency and fine surface finishes.
-
Versatility: Suitable for manufacturing automotive components, household appliances, medical devices, and everyday products. It also supports multi-shot molding (e.g., 2K/3K injection) for multi-color or multi-material applications.
