The automotive industry is choosing custom plastics over metal or ceramic parts at a higher rate than ever because today’s engineering-grade resins and polymers are lightweight, durable, and high-performing, able to withstand extreme heat and friction. By using plastics, vehicles have improved fuel efficiency, are less expensive to produce, and the exterior elements are more impact and scratch-resistant to their ceramic or metal counterparts.
Because the double-sided tooling used for automotive plastic injection molding is more complex, it has a longer lead time than thermoforming, usually 16 to 20 weeks rather than 14 weeks. However, there are several benefits to choosing injection molding automotive parts.
High Volume Orders
In order to withstand mass-producing plastic car parts, our tooling is made from heavy gauge steel, aluminum, or beryllium-copper alloy. Whether you need a single, high-volume production run or multiple orders, being able to re-use the injection mold significantly reduces the per-unit cost of your plastic parts.
Once the automotive injection mold is ready for use, this process allows for rapid manufacturing. There’s minimal, if any waste, so once the plastic parts are out of the mold, they can be finished or assembled as needed.
Complex or Advanced Component Designs
Plastic automotive parts are often incredibly detailed with varying thicknesses, raised edges, and sharp corners or angles. An injection mold allows for these details in a way that can’t be obtained through other production processes.
Body panels and large pieces can be formed through thermoforming, but knobs, dials, and other small automotive components are more easily produced through injection molding because we can create multi-cavity molds to speed up the manufacturing processes.
