Product Introduction
Fiberglass-reinforced plastic ovens are critical equipment for the curing, heating, and drying of FRP products, widely used in industrial manufacturing, particularly playing a vital role in composite material molding processes.
Core Features and Technical Requirements
Temperature Uniformity and Temperature Control Accuracy
Fiberglass-reinforced plastic products are highly sensitive to temperature variations during the curing process, necessitating uniform temperature distribution within the curing chamber. An intelligent PID temperature-control system can achieve a temperature control accuracy of ±1°C, and when paired with multi-point temperature-sensing probes—such as dual NTC probes—it enables real-time monitoring and dynamic compensation for temperature fluctuations, thereby preventing localized overheating or uneven curing.
Hot-air circulation design
An efficient hot-air circulation system is essential for ensuring uniform heating. Large ovens are typically equipped with dual-side or multi-directional circulating fans—often six on each side—and are further enhanced by high-pressure top-mounted fans to intensify airflow turbulence, thereby ensuring thorough heat distribution across the workpiece surface. 3D hot-air circulation technology effectively minimizes temperature gradients and improves curing quality.
Thermal Insulation and Energy-Saving Structure
To reduce energy consumption, ovens typically employ a double-walled cabinet design, with 80–100 mm of ceramic fiber insulation sandwiched between the inner and outer walls, which significantly minimizes heat loss. Some models incorporate advanced insulation panels, further enhancing energy efficiency and achieving energy savings of more than 30%.
Safety and Protection Design
● The cabinet door is equipped with a high-temperature-resistant tempered glass observation window for real-time monitoring of the internal conditions;
● Equipped with over-temperature protection and an automatic timing alarm with power-off function to prevent accidental overheating;
● The enclosure and door assembly feature excellent thermal insulation, ensuring that surface temperatures remain controllable during operation to minimize the risk of burns.
Customization capability
Due to the wide range of dimensions for FRP products, ovens are often available as custom, non-standard solutions. For example, one project involved a customer ordering a large oven measuring 7 meters in length, 4 meters in width, and 3 meters in height, which was assembled on-site. The inner liner can be made of stainless steel or galvanized sheet, depending on the specific corrosion-resistance requirements.
Application Scenario Expansion
In addition to conventional curing, certain high-end ovens can also perform oxygen-free curing under an inert-gas atmosphere, thereby preventing material oxidation and making them suitable for manufacturing high-precision molds or aerospace components. Furthermore, in exhaust-gas treatment systems, fiberglass-reinforced plastic activated-carbon units must be paired with high-temperature-resistant ovens for regeneration.
Hengshui Deli Fiberglass Equipment Co., Ltd. is a technology‑driven manufacturing enterprise primarily engaged in the development, design, and production of fiberglass winding equipment, extrusion equipment, glass fiber rebar equipment, fiber‑reinforced mesh equipment, and fiberglass molds.
Entering the field of composite materials. One company has successfully absorbed and adapted glass fiber extrusion molding technology imported from abroad, applying it to relevant domestic institutions while also offering domestically produced glass fiber pipe winding and extrusion production lines. The company has since licensed its glass fiber extrusion technology to numerous enterprises.
In recent years, as China’s composite materials industry has continued to develop in depth, the company has developed a series of glass fiber extrusion equipment to meet the evolving needs of the glass fiber industry. To date, the company has supplied large numbers of extrusion production lines to numerous customers. Practical experience has demonstrated that our products are highly reliable and better aligned with the actual process requirements of China’s glass fiber pipe winding and extrusion industries. We can provide customers with the following services:
- Based on the needs of different glass fiber products, we provide corresponding glass fiber winding machine units, pultrusion line units, and supporting auxiliary equipment.
- Layout design for winding, extrusion, and double-wall coating plants and workshops;
- Provide technical guidance documents for the design and assembly of formulations, molds, and preformed components.
- Train technical operators and assist customers in retrieving qualified products.
- Customized according to customer needs.
Our commitment is “Integrity First, Precision Manufacturing.” We firmly believe that providing comprehensive services is more important than simply making sales. We are happy to offer pre‑sale consultations and industry‑related insights to help you create greater profit margins.
Hengshui Deli Fiberglass Equipment Co., Ltd. is eager to collaborate sincerely with both new and existing customers and work together to create a bright future!
