FRP planters are manufactured using molding techniques, where glass fibers are layered with polymer resin inside a mold shaped like the desired planter. The fibers are impregnated with resin and cured under controlled heat or room temperature to form a rigid, lightweight, and durable structure. Depending on the design, hand lay-up, compression molding, or resin transfer molding (RTM) methods are used. After curing, the planter is demolded, trimmed, and polished to achieve smooth edges. Surface finishing is then done with gel coats, paint, or decorative textures to provide UV protection, water resistance, and an attractive appearance. Custom designs, colors, and shapes are created by using different molds and finishes, making FRP planters suitable for both indoor and outdoor applications.
