One of the most popular techniques for making similar plastic objects in large quantities is injection molding.

To successfully produce cost-effective, high-quality parts, as with any process, it is crucial to comprehend the precise design constraints that must be followed to enable the benefits that are immediately apparent.

To assist, we have succinctly outlined the benefits and drawbacks to take into account.

Advantages of Injection Molding

Rapid production and great productivity

Injection molding can crank out a staggering number of pieces per hour. Speed might range from 15 to 120 seconds per cycle depending on the complexity and size of the mold.

Reduced labor costs

Plastic injection molding is an automated process that is controlled and managed by a single operator, with machines and robotics handling the majority of the work. Automation lowers manufacturing costs since there are fewer overhead expenses.

Flexibility in design.

Very high pressure is applied to the molds themselves. Because of the increased pressure on the plastic inside the molds, elaborate or complex shapes can be produced as well as parts with a lot of detail imprinted on them.

Production with high output.

Before the tooling needs to be serviced, thousands of pieces can be manufactured.

Wide range of materials.

There is a wide range of polymer resins available. The usage of multiple plastic materials at once is also possible; TPE, for instance, can be over-molded onto PP pieces.

Product uniformity

Injection The second part you manufacture will be similar to the first one because the molding is a repeatable operation, etc. When trying to make high tolerances and reliable parts in large volumes, this is a significant advantage.

Superior Strength

Fillers may be used in the molding material during the plastic injection molding process. These fillers can assist increase the strength of the finished product by reducing the density of the plastic while it is being molded.

Disadvantages of Injection Molding

Expensive tooling and protracted lead times for setup

Because of the necessary design, testing, and tooling, upfront expenditures are significant. Following the original design and prototyping (often using CNC or 3D printing), a prototype mold tool is created to mass produce the part. Finally, only following thorough testing throughout both steps, a part can be injection molded.

Restrictions on part design

Plastic components must be built with injection molding in mind and adhere to the fundamental injection molding guidelines.

Costly small-run parts can be an issue

The setup process can take a while because of the complexity of the tooling and the need to empty the machine before producing the following item. Because of this, it has always been believed that injection molding is too expensive for short runs of parts.
