How to Manufacture Fiberglass Helmets
Manufacturing fiberglass helmets involves a precise and multi-step process. If you’re considering making fiberglass helmets or buying them from manufacturers, understanding the process is essential.
Step 1: Preparing the Helmet Mold
The first step in producing a fiberglass helmet is creating or obtaining a mold. Manufacturers use molds to shape the helmet and define its size. You can either design a custom mold or buy a pre-made one. The mold needs to have smooth, well-defined edges for easy removal after the fiberglass curing process.
Before you start applying fiberglass, it’s essential to prepare the mold. Clean it thoroughly to remove any dirt, oils, or residues. Then, apply a release agent to the surface. This helps the fiberglass peel off easily once it cures. Manufacturers often use wax, silicone-based sprays, or other specialized release agents.
Step 2: Applying Gel Coat
The next step is applying a gel coat to the mold’s surface. Gel coat provides a smooth, shiny finish on the outer layer of the helmet. It’s an important step for both aesthetic and protective purposes.
Mix the gel coat with a hardener and apply it evenly to the mold. This layer must cure for 15-30 minutes before proceeding. The gel coat ensures the helmet has a high-quality, smooth outer surface once the manufacturing process is complete.
Step 3: Laying Fiberglass Layers
The core strength of fiberglass helmets comes from the layers of fiberglass cloth. Fiberglass manufacturers in China often use high-quality fiberglass fabrics for this step. Start by cutting the fiberglass cloth into strips or patches that will fit inside the mold.
Next, mix the resin with a hardener, following the manufacturer’s instructions. The resin acts as a bonding agent, fusing the fiberglass layers together. Apply the resin to the mold or over the gel-coated surface. Lay the first piece of fiberglass cloth into the mold, ensuring it fits snugly. Then, apply more resin to the cloth until it is completely saturated.
Repeat the layering process, ensuring each layer is fully saturated with resin. Typically, fiberglass helmet manufacturers use 4-6 layers of cloth for optimal strength and durability. Each layer adds structural integrity to the helmet.
Step 4: Curing the Helmet
After applying the fiberglass layers, the helmet must cure. Allow the resin to harden fully. Curing times can vary depending on the resin type, temperature, and humidity. In most cases, the curing process takes several hours to overnight. Fiberglass helmet manufacturers in China ensure proper curing to guarantee the strength and quality of the helmets they produce.
Step 5: Demolding the Helmet
Once the helmet has fully cured, it’s time to remove it from the mold. A well-applied release agent ensures that the helmet comes out of the mold easily. Take care not to damage the edges during this process. If the mold is properly prepared, the helmet should come out smoothly with a high-quality finish.
Step 6: Trimming and Finishing
Now that you have the helmet shell, you need to trim any excess fiberglass. Use a rotary tool or saw to carefully cut around the edges of the helmet. Sand the surface to remove any rough areas or imperfections. This process is essential for achieving a smooth, polished finish.
After sanding, you may decide to paint or decorate the helmet. Applying paint not only enhances the helmet’s appearance but also adds an extra layer of protection. Many manufacturers offer custom colors and designs, especially for helmets used in sports or motorcycling.
Step 7: Adding Padding and Straps
For comfort and safety, manufacturers install padding inside the helmet. This padding is often made of foam and helps absorb impact. Additionally, chin straps and retention systems are added to secure the helmet on the wearer’s head.
Step 8: Quality Control
Once the helmet is complete, it undergoes a strict quality control process. Manufacturers test the helmets for durability, strength, and comfort. For helmets used in high-risk environments, safety standards are critical. Manufacturers like TopriseSafety ensure that their fiberglass helmets meet international standards.
Fiberglass Helmets vs. PE and ABS Helmets
Fiberglass helmets differ significantly from helmets made from PE (Polyethylene) and ABS (Acrylonitrile Butadiene Styrene) materials. Let’s compare these three types:
- Weight: Fiberglass helmets are lighter than PE and ABS helmets. While PE helmets are relatively lightweight, fiberglass is often chosen for its superior strength-to-weight ratio.
- Durability: Fiberglass helmets are more durable than PE or ABS helmets. The multiple layers of fiberglass provide higher impact resistance.
- Production Process: Fiberglass helmets take longer to manufacture due to the layering and curing process. In contrast, PE and ABS helmets are usually produced via injection molding, which is faster and more cost-effective.
- Cost: Fiberglass helmets tend to be more expensive due to the labor-intensive production process. PE and ABS helmets are cheaper because of faster, automated manufacturing methods.
Why Are Fiberglass Helmets More Expensive?
Fiberglass helmets are more expensive because of the materials used and the time-consuming manufacturing process. The process of layering fiberglass cloth and resin takes longer than the injection molding used for PE and ABS helmets. Additionally, the cost of high-quality fiberglass and resin is higher than that of PE or ABS plastics. The curing process also adds to the production time and cost. However, the benefits—such as greater strength, durability, and a more refined finish—justify the higher price.

Benefits of Fiberglass Helmets
As one of the top fiberglass helmet manufacturers since 2009, TopriseSafety would like to clarify the benefits of this kind of helmets here.
High Durability and Impact Resistance
Fiberglass helmets are known for their exceptional strength. The material is inherently more durable than many other helmet options, such as plastic helmets made from PE (Polyethylene) or ABS (Acrylonitrile Butadiene Styrene). This durability makes fiberglass helmets particularly suitable for construction, where workers are exposed to falling objects, heavy equipment, or other potential hazards. Fiberglass can absorb impacts better and is less likely to crack under force, offering superior protection.
Lightweight Design
Despite their strength, fiberglass helmets are relatively lightweight compared to helmets made from metal or thick plastic. This is important for comfort, as construction workers wear these helmets for long hours. A lightweight helmet reduces neck strain and fatigue, allowing workers to focus on their tasks without discomfort.
Heat Resistance
Fiberglass is naturally resistant to high temperatures, making it an excellent choice for construction workers who may be exposed to hot environments. Whether working near welding stations, in areas with high sunlight, or in extreme weather conditions, fiberglass helmets can offer protection against heat-related risks, without warping or losing their shape.
Electrical Insulation
Some fiberglass safety helmets are designed with electrical insulation properties. This makes them suitable for workers in environments where there is a risk of electrical hazards. For example, electricians or workers in power plants benefit from helmets that provide protection against electrical shocks. However, it’s important to check the helmet’s specifications to confirm its electrical insulating capabilities.
Shock Absorption
Fiberglass helmets provide excellent shock absorption. When subjected to sudden impacts or drops, the material can distribute the force over a larger area, minimizing the risk of head injuries. The shock-absorbing qualities are particularly valuable in construction environments where falling tools or debris can cause serious harm.
Corrosion and Chemical Resistance
Construction sites often involve exposure to harsh chemicals, solvents, or rust-inducing conditions. Fiberglass helmets are highly resistant to corrosion, ensuring they remain effective even in environments where other helmets might deteriorate. The material does not rust, corrode, or degrade when exposed to moisture or chemicals, which prolongs the lifespan of the helmet.
Vented and Breathable Designs
Many modern fiberglass helmets come with built-in ventilation systems. These ventilation holes or mesh linings help improve airflow and reduce the buildup of heat inside the helmet. This feature is particularly beneficial for workers in hot climates or those working under the sun for extended periods. Increased airflow reduces sweating and discomfort, helping workers stay cool and focused.
Long-Lasting Performance
Fiberglass helmets are built to last. Unlike plastic helmets, which may degrade over time, fiberglass maintains its strength and protective qualities for many years. The longevity of these helmets means that construction companies can rely on their protective performance for extended periods, reducing the need for frequent replacements.
Resistance to UV Radiation
Fiberglass helmets are resistant to ultraviolet (UV) radiation, which can degrade certain materials over time. This is especially beneficial for construction workers who spend a lot of time outdoors, exposed to direct sunlight. The helmet’s resistance to UV rays ensures that it maintains its structural integrity and appearance even in harsh sunlight.
Affordable in the Long Term
While fiberglass helmets may have a higher initial cost compared to plastic helmets, their durability and longevity make them more cost-effective in the long run. Since they require fewer replacements and maintenance, fiberglass helmets are a wise investment for construction companies looking to reduce operational costs.
