4 Reasons That Plastic Injection Molding is Preferred Over Fiberglass

Plastic injection molding is used to manufacture various plastic parts. It was invented in the late 19th century and has become the preferred method among automobile manufacturers for creating automotive plastic components. Although automotive plastic components can be produced using fiberglass, injection molding has usurped it because of its many benefits. Some of the reasons why plastic injection molding is preferred over fiberglass are explained below.

Increased Production Efficiency

Compared to fiberglass, the plastic injection mold manufacturing process is exceptionally rapid. A high production output rate is achievable, thereby increasing efficiency and cost-effectiveness. The speed of production varies depending on the complexity of the mold, but each cycle takes roughly 15-120 seconds. Because of the short time between cycles, a larger number of molds can be manufactured in a shorter length of time, potentially improving revenue and profit margins.

Strength and Durability

Plastics have improved in strength and durability over time, and today’s lightweight automotive plastic components can resist even the toughest environments on par with metal parts. The plastic injection method provides a one-of-a-kind way to make these parts as sturdy and long-lasting as possible. In plastic injection molding, fillers can be used in the molds. These fillers lower the density of the plastic while simultaneously increasing the strength of the molded item. Plastic can be up to 30% lighter than fiberglass, boosting fuel efficiency significantly.

Lower Labor Costs

Plastic injection molding is a more automated process than fiberglass production. The majority of the work is done by machines, robots, and computers, all of which may be controlled and managed by a single person. Automation aids in the reduction of production costs by lowering labor expenses and total overhead. Post-production work is usually low since the parts typically appear finished upon manufacture.

Complex Geometry and Design

Due to the incredibly high-pressure injection molds are subjected to, they are far more customizable than fiberglass molds. As a result, the component’s design can accommodate a great number of details. Furthermore, because of the high pressure used during the molding process, complex and intricate designs that would otherwise be too difficult and expensive to produce can be designed and manufactured.

Due to the advantages listed above, injection molding will remain the dominant method for producing automobile plastic components over fiberglass. Do you require automotive plastic components for your vehicle production? Please do not hesitate to contact us!
