What is Injection Molding?

Plastic injection molding is a major molding process. With the help of an injection molding machine, granular plastic raw materials are melted and liquefied. The process takes place in a closed cylinder, in which a screw conveyor ensures plasticization of the plastic by friction and external heat. After the plastic is melted, it is injected into a mold (also called an injection mold) under high pressure. The shape and surface structure of the finished injection molded part are determined by the cavity in the injection mold (called the cavity). The plastic material injected into the tool cools in the cavity and returns to a solid state. The injection mold can then be opened and the finished injection molded part can be removed. Since the same mold is used for each part of the injection molding process, the quality of each part is consistent. Compared with CNC machining or even 3D printing, injection molding also has the most diverse materials, colors, surface treatments, finishes and surface textures.

Benefits of Custom Plastic Injection Molding Services

There are numerous reasons to consider choosing injection molding for your project. Some of the most notable advantages include the following:

  • Customizability. Your tooling/mold will be custom-built for injection molding. Additionally, parts created this way can be easily colored using additives, creating aesthetically pleasing products.
  • Cost-effectiveness. The automation utilized in the injection molding process significantly reduces overhead costs, allowing a sole operator to oversee the molding process.
  • Accuracy. With a properly designed mold, the injection molding process can ensure tight tolerance accuracy molding to meet customer demand to print specifications.
  • Efficient use of materials. The injection molding process reduces unnecessary plastic waste, as the material is injected directly into the mold during production.
  • Easy reclamation and recycling. Any unused material can easily be melted down for reuse.
  • Enhanced strength. Plastics have an incredibly high resistance to wear and can be injected with fillers during the molding process to create additional strength.

Plastic Injection Molding vs. 3D Printing

While both 3D printing and injection molding are manufacturing processes with their own advantages and disadvantages, their approaches are very different. Injection molding is cheaper for larger products, while 3D printing is more expensive but allows you to make changes at any stage of production. Injection molding provides uniform quality and high production volumes, while 3D printing provides high fidelity at low production volumes. However, 3D printing allows for more design flexibility than injection molding.
High Volume die Casting parts

Plastic Injection Molding vs. Die Casting

Die casting and plastic molding are two common manufacturing processes used to produce parts with complex geometries. The main difference between the two is the materials used. Die casting uses metals, while injection molding uses plastics or polymers. Die casting is well suited for producing parts that require high strength and durability, while injection molding is better suited for producing parts that require complex designs and tight tolerances.
