What are the types of plastic molds?

Plastic molds are indispensable tools in plastic processing, and can be classified into various types based on their structure and purpose. The following are different types of articles about plastic molds, hoping to be helpful to you:
Injection Molds:
Injection molds are one of the most common and widely used plastic molds. They are used to inject melted plastic materials into the mold cavity, forming the required plastic products through cooling and curing. Injection molds are usually composed of mold cavities, mold cores, ejector pins, nozzles, and other components, and can be used to produce plastic products of various shapes and sizes, such as bottles, boxes, pipes, etc.
Extrusion Molds:
Extrusion molds are mainly used to produce continuous plastic products, such as pipes, films, sheets, etc. They form the desired shape and size by extruding melted plastic material from the mold mouth, cooling and stretching it. Extrusion molds usually include mold heads, extrusion outlets, cooling devices, and other components, suitable for high production and continuous production needs.
Blow Molds:
Blow molding molds are used to produce hollow plastic products, such as bottles, containers, etc. They inject melted plastic material into the mold cavity and blow air inside the mold to make the plastic material adhere to the mold wall, forming a hollow structure. Blow molding molds usually include mold cores, mold walls, blowing devices, and other components, which can produce hollow plastic products of various sizes and shapes.
Compression Molds:
Compression molds are mainly used to produce plastic products with thick walls and complex structures, such as automotive parts, furniture accessories, etc. They solidify and shape by placing melted plastic materials into the mold cavity and under certain temperature and pressure. Compression molds typically include upper molds, lower molds, pressure plates, and other components, suitable for producing plastic products with high strength and precision requirements.
Rotating Molds:
Rotating molds are mainly used to produce hollow and complex shaped plastic products, such as toys, storage boxes, etc. They inject melted plastic material into the rotating mold cavity and rotate inside the mold to evenly cover the entire mold wall to form the desired shape. Rotating molds typically include mold cavities, rotating devices, cooling systems, and other components, suitable for producing large and special shaped plastic products.
The above is a brief introduction to different types of plastic molds, each with its specific purpose and advantages. Suitable mold types can be selected for production according to actual needs.
