Why is your outdoor enclosure cracking after six months? Or why did that prototype shatter when dropped from a workbench? If you’re asking these questions, you’re likely battling the “Triangle of Trade-offs” in thermoplastic selection: Cost, Toughness, and Weatherability. At BLG Fiberglass, we see this constantly in our vacuum forming projects. You want the price […]

There is a specific feeling of dread that every product designer knows. It happens when you’re standing on the shop floor, watching the machine cycle. The sheet heats up, the mold raises, the vacuum pulls tight, it looks perfect. Then, the operator hits “release.” And nothing happens. The part is seized onto the tool. The […]

We see it all the time. A startup designs a brilliant new device enclosure or an automotive aftermarket part. They 3D print the first prototype, and it looks great. Then they print ten more for beta testing. Still good. But then comes the order for 500 units. Suddenly, their “rapid” prototyping lab turns into a […]

In the world of custom manufacturing, engineers and product designers are often stuck between a rock and a hard place. You either pay astronomical tooling costs for injection molding or endure the slow, labor-intensive process of fabricating parts by hand. But what if there was a middle ground? A sweet spot that offers speed, durability, […]

Wind energy is one of the cornerstones of all global renewable energy strategies. Modern wind farms efficiently transform natural airflow into electric power, but the usually not-recognized star of the show is the blade of the wind turbine. These blades need to be large, strong, and lightweight, while withstanding extreme environmental conditions. The material making […]

The terms glass fiber and fiberglass are often used interchangeably with regard to materials in construction, manufacturing, or industrial applications. While the two are related materials, they differ in purpose and characteristics. Knowing the difference will help you make smarter decisions for your projects. What is Glass Fiber? Glass fiber is manufactured from very fine […]

You might not think about fiberglass every day, but it is one of the most versatile and widely used materials in the world. From cars and boats to medical equipment and wind turbines, fiberglass is valued for being strong, durable, and lightweight. These qualities are exactly why so many industries depend on it.  In this […]

Fiberglass is one of those materials that works behind the scenes in everyday life – found in everything from cars and boats to medical devices and industrial machinery. But here’s the thing: not all fiberglass is created equal. Each type has its own unique properties, and choosing the right one can make a big difference […]

Fiberglass and composite materials are taking on a central role in manufacturing. They influence how we create everything from cars to boats to medical devices. Their lightweight nature, strength, and flexibility make them essential in various industries. As we move into 2026, several trends are emerging that are changing the landscape of composites. Manufacturers are […]
