How Injection Molding Helps Drive the Electric Vehicle Industry

After a slow start and a general reluctance among established automakers to embrace electric vehicles, the industry has kicked into high gear. No longer is Tesla the sole independent producer of electric vehicles; today, there are many prominent brand names, including Ford and Chevrolet, navigating the EV space. Even luxury brands, such as BMW, now offer all-electric vehicles. 

With this growing movement to adopt EV worldwide, the sector — already a vigorous, multibillion-dollar industry — seems poised to explode even more in size and value over the next decade. With this pace of change, massive growth in consumer demand, and increase in the number of players, there are genuine concerns about achieving reliable production. Sourcing suitable materials to continue growing and satisfying customers requires a serious heavy-lift effort. The EV industry must embrace several technologies, chief among them plastic injection molding for the automotive industry. 

Using injection molding for electric vehicles, automakers can tap into a flexible, scalable, and highly mature technology with international and domestic production capacity. Modern plastic molding processes remain cutting-edge, incorporating new techniques and technologies. Simultaneously, they provide a highly versatile solution for meeting many material needs within every electric vehicle. 

Ahead, we get into how injection molding in transportation is paving the way for the future of driving.

Injection Molding for Electric Vehicles: A Whole-Body Option

The versatility of plastic injection molding is by far one of its biggest strengths for EV manufacturers. This process does not produce just one or two critical components. Instead, you can apply injection molding to many car parts. Molding suits everything from interior trim components on the dashboard to everyday touchpoints like the charging connector. Even with all the metal pins necessary inside a charging gun, advanced injection molding techniques ensure it is possible to create these assemblies quickly and efficiently.

Even components that must withstand extreme conditions, from a corrosive chemical environment to high heat levels, can be produced through injection molding. Molding of components for the electrical sector could yield critical improvements, too. Future battery compartment redesigns could rely on molding for more robust housing or efficient storage designs. Adding this capability to your technology lineup today ensures broad access to critical parts.

Rapid Development Processes for EV Injection Molding Make the Difference

The automotive industry moves rapidly to meet consumer demand and improve vehicle models from year to year. The world of electric vehicles moves even faster, especially with intense competition driving manufacturers to seek innovations wherever possible. Rapid prototyping, which is possible through injection molding, can swiftly propel projects toward achieving such critical milestones. 

Rapid prototyping allows for ideas from the drawing board to be put into tangible materials; test proofs of concepts to be run on shorter timelines, opening the door to rapid iteration. With this technology, you can create a part design ready for full-scale production and inclusion into an EV sooner rather than later.

Mass Production Runs Support Automaker-Level Needs

The most suitable injection molding partners can help you build a highly resilient supply chain to meet the most extensive needs. The repeatable nature of injection molding means you can see hundreds of thousands of product outputs from one extended production run. That level of volume keeps all the parts you need close at hand for the assembly line. Investing in the capacity for large-scale production and the necessary inventory warehousing now means EV makers can also guard against future supply chain disruptions.

Material Qualities Contribute to Better Performance

The convenience, versatility, speed, and scale of injection molding processes make this manufacturing method an obvious choice for supporting today’s EV needs. However, another fundamental reason to choose plastics is that their material properties perfectly suit electric vehicles. Much lighter than comparable parts made in metal, plastic lowers overall vehicle weight substantially and thus contributes to an extended range on a single charge.

That’s before we even consider the resins suitable for heavy-duty use, capable of withstanding everyday wear and tear. Add in chemical and heat resistance, and finding plastic materials with the perfect profile for EV use cases is simple.

Examples of Plastic Molding for Electrical Vehicles

  1. Transportation injection molding. Vital in the transportation industry for years, injection molding now extends to EV manufacturing, with molding used to create various components.
  1. Door components and panels. Many internal elements of car doors, window switches, and lock toggles, as well as large interior panels or door assemblies, use plastic injection-molded parts.
  1. Plastic covers and housings under the hood. Some vehicles have complete injection molded engine covers for a precise fit to assist with dampening noise or protecting internal parts. 
  1. Battery cell systems and cell protection. While the battery cells use advanced materials and designs, the modules that group them often use plastics.
  1. Dashboard elements. EV designs feature innovative dashboards with ample glass and electronic displays, but plastic still surrounds these info centers, providing definition and shape.
  1. Air conditioning system components. The vents and vent controls of many AC systems come from custom-designed molds.

With so many potential areas to apply molding of components for the electrical sector, the right partner makes a difference.
