Injection molding is a molding process for producing parts mostly in plastic material. In the process, material for the part is fed into a heated barrel, mixed, and forced into a mold where it cools and hardens to the configuration of the mold cavity or surface relief pattern. It has a very broad application ranging from tooth brush, DVD/Blu-ray disk, cosmetic/pharmaceutical packaging, to biomedical devices such as scaffolds and micro-needles. More recently, injection molding is applied for the fabrication of microfluidic devices and drug delivery. The key advantage for injection mold is its low cost and high throughput, compared to other competing techniques such as hot embossing.

注塑成型是一种主要用塑料材料生产零件的成型工艺。在此过程中，零件的材料被送入加热的桶中，混合，并被迫进入模具，在那里它冷却并硬化到模腔或表面浮雕图案的配置。它具有非常广泛的应用，从牙刷，DVD/蓝光光盘，化妆品/药品包装，到生物医学设备，如支架和微型针。最近，注射成型被应用于微流体装置和药物递送的制造。与其他竞争技术（如热压）相比，注塑模具的关键优势是其低成本和高产量。
