What is Injection Mold Design?
Custom injection molding is a kind of manufacturing process that is used to manufacture plastic parts by injecting heated molten plastic material into a pre-designed mold, which will form into desired parts when it solidifies upon cooling.
The molds are typically made from steel or aluminum, and are processed according to the product design specification.
During the production process, the injection molding machine injects the plastic material into the mold cavity with high pressure, where it will release from the molding after it is cooled down.
This process can be repeated multiple times, and with a flexible design and material selection, the business can quickly scale up from just prototype to mass production while ensuring a consistent quality.
