Our experience in custom fiberglass molding and part assembly has made us a go-to partner for manufacturers seeking lightweight, durable, and cost-effective components designed for demanding on-road environments.

One of Arrowhead’s core specialties is producing complete, one-piece fiberglass front ends like the one shown here. These assemblies are delivered with pre-installed metal framework on the backside, making them fully compatible and ready for mounting directly to the bus chassis. This integration streamlines final assembly for OEMs, reducing build time and ensuring consistent part fit and finish.

Our expertise in fiberglass bus parts extends well beyond front-end assemblies. We have a long history of supplying a wide variety of molded components for both interior and exterior bus applications. Whether you need a structural component with steel reinforcement or a finished part with hinges, latches, and insulation installed, Arrowhead can deliver a production-ready solution.

Fiberglass bus parts we have supplied include:

• Complete rear-end assemblies

• Fiberglass rear doors with internal steel tube reinforcement

• Molded fiberglass step-walls for improved durability and strength

• RTM-Lite transition panels for seamless interior and exterior integration

• Exterior fiberglass engine covers, fully assembled with hinges, latches, and thermal insulation

Each part is engineered to meet the structural, thermal, and cosmetic requirements of modern bus designs. With decades of composite molding experience and in-house capabilities for both open and closed mold production, Arrowhead is ready to support your next bus project with reliable, high-performance fiberglass components.

The open molded fiberglass hood is a popular solution for large, contoured components in the transportation industry—especially in applications like buses, trucks, and specialty vehicles. One of the key reasons fiberglass is the preferred material is the significantly lower tooling cost compared to other molding processes. This is especially important for large parts that feature compound curves, complex surfaces, or molded-in details. Open molding allows manufacturers to produce durable, cost-effective hoods without investing in expensive, multi-cavity tooling systems.

An additional benefit of using an open molded fiberglass hood is the material flexibility it offers. The type and quality of fiberglass reinforcement—such as chopped strand mat, woven roving, or multi-axial fabrics—can be selected based on the strength, weight, and cost requirements of the project. This customization enables design engineers to fine-tune performance characteristics, ensuring long-term durability with minimal added weight. This is particularly advantageous in industries where reducing vehicle weight can lead to increased fuel efficiency and improved overall performance.

The open molding process also provides flexibility in integrating functional features into the hood. Structural brackets, reinforcing ribs, hinge mounts, and other hardware can be mechanically fastened, laminated in place, or bonded to the backside of the part during or after the molding process. These additions enhance both the strength and usability of the hood, allowing for seamless assembly with surrounding vehicle components.

Arrowhead specializes in producing high-quality open molded fiberglass hoods and similar components, offering engineering support, in-house tooling, and precision manufacturing to meet your unique project requirements. Whether you need a single custom prototype or a low-to-medium production run, open molded fiberglass offers the versatility, cost savings, and performance you’re looking for.
