Printer Metal Injection Molding MIM Parts

Low-volume Injection Molding Vs. Traditional Injection Molding

Injection molding is a major process used in the plastics manufacturing industry. The process is cost-effective, highly repeatable, and can produce high-quality parts in large quantities, making it widely used to produce large quantities of identical parts with tight tolerances.

Injection molding is a fast, high-intensity process that uses high temperature and pressure to inject molten material into a mold. The choice of molten material depends on the scope of the manufacturing project. The most popular materials are various thermoplastics, including ABS, PS, PE, PC, polypropylene, and polyurethane, etc. In addition, metals and ceramics can also be used for injection molding. The mold contains a cavity that can contain the injected molten material, and the cavity design can closely reflect the final characteristics of the part.

The mold is usually made of metal using CNC machining technology or spark machining technology (EDM). These high-cost industrial methods require specialized equipment, high-end software, and highly trained personnel. It usually takes four to eight weeks to produce a metal mold, and the cost ranges from US$2,000 to more than US$100,000, depending on the shape and complexity of the part. For low-volume parts, the cost, time, specialized equipment, and skilled personnel required to create molds using common moldmaking metals and manufacturing methods often greatly limit injection molding at this scale. However, there are alternatives to using metal molds. Using in-house 3D printing to create injection molding molds for prototyping and low-volume production can significantly reduce costs and time compared to metal molds, while still producing repeatable, high-quality parts.
