The injection mold is also known as one of the most common methods in mass fabrication. Here the molten material, which in most cases is a plastic, metal, or rubber, is injected into a mold cavity so that a more intricate shape may be formed with high accuracy and precision. In this way, one can mass-produce identical parts maintaining the quality.

Key Features:

• Process Overveiw: The material is heated until molten, injected at a high pressure into a mold, cooled to allow the material to solidify, and ejected as a solidified part. This allows rapid production, thus the process is economical. Minimum waste as well.
• Material Versatility: Common materials include thermoplastics (polyethylene, ABS), thermosetting plastics, and metals (for metal injection molding), thus offering various applications.
• Common Applications: The list of industries includes automotive (dashboard panels, housings), consumer goods (toys, packages, electronic enclosure), and medical devices (syringes, prosthetics).

The relevance of injection molding lies in the ability to produce parts with complex geometries with superior quality and durability at affordable prices. In the automotive sector, injection-molded components go a long way in achieving lightweight and fuel-efficient vehicle designs. Being a precision process, injection molding also lends itself to easy assembly and durability in the consumer electronics sector. Innovations such as 3D-printed molds and the use of biodegradable plastics make the process increasingly efficient and sustainable, making injection molding a key manufacturing method of today.
