Types of Plastic Molds Used by Injection Molding Manufacturers?

Injection molding is the process of producing high-quality and precision plastic parts. In this process, a balanced form of temperature and pressure maintains to produce high-quality items. An injection method uses to supply the raw plastic resin inside the mold. The mold is a frame or dye for shaping the final product. Mold makes from metals or other quality metals. This process is known as High Quality Injection Molding with precision products. It is also a cost-effective process because it can produce millions of products in volume with low processing time. Nubs Plastics Inc shares information about different types of plastic molds used by injection molding manufacturers.

Different Types of Injection Molds:

Plastic molds are special tools that design for the plastic industry and plastic molding machines. Molds produce products with accurate dimensions and complete structures. The followings are different types of molds

Injection Molds: 

It is one of the most known mold processes for the production of thermoplastic parts. In this process, a plastic machine uses for processing the injection molds. First of all, raw plastic is hot melted in a heating cylinder. After that, it pushes by a screw or plunger is into the mold cavity through the pouring mechanism of the injection molding machine. Finally, after the plastic cools and hardens, ejected out from the mold. The product comes out in the finished form.

The injection molding machine process consists of many components. These are molding components, pouring system, guiding, introduction mechanism, temperature control system, ejection system, supporting tool, etc. According to Injection Molding Manufacturers, this process is better suitable for thermoplastic products. The products made through this process uses across many sections of human life like daily necessities, automobiles, electronics, etc.

Blow Molding Process:

The blow molding process generally uses for shaping plastic containers. This process applies to making hollow plastic products like beverage bottles, daily chemical products, etc. In this process principle, the injection molding process includes the extrusion blow molding technique, injection blow molding process, injection extension blow molding, multi-layer blow molding, plate blow molding techniques, etc. The injection-extension blow molding process is also known as the injection blow molding technique. This process is also quite suitable for the production of thermoplastic parts. The blow molding process generally has a simple structure, and its raw material is mostly carbon.

Extrusion Mold Process:

The extrusion mold process uses for shaping and continuous production of plastic parts. This process is also known as an extrusion molding machine head. The products made through this process are pipes, rods, monofilaments, sheets, cables, wires and films, etc.

The main production equipment for this process is a plastic extruder. In which solid plastics melt under the heating and pressure mechanism of the extruder. After that, it makes continuous plastic parts with predefined section and cavity shapes. Raw materials for this process are carbon structural steel, alloy tools, etc. Some extrusion molds equip with wear-resistant materials like gold and stone. This process is quite different from injection molding and compression molding processes and is better suitable for the production of thermosetting plastic products.

Compression Mold Process:

This process divides into two sections. One is compression molding, and another is pressure molding. It also uses mainly thermosetting plastics. Its corresponding equipment is a pressure molding machine. In this process, the first mold heats, then predefined plastic powder puts into the mold cavity and the feeding chamber. Then mold closes so that plastic becomes soft as well viscous under the mechanism of temperature and pressure. Finally, the solidified product ejects from the mold. One of the big differences between injection molding and compression molding is that the injection molding process doesn’t have a separate feeding chamber.

Conclusion

The injection molding process is quite-useful for the production of plastic parts. According to Injection Molding Manufacturers, different techniques of plastic production processes are beneficial for different segments. Vivid plastic parts require a different methodology for production.
