As production scales up, single-door ovens can no longer meet the demands of large-volume workpiece baking. Simultaneously, factories place higher demands on process traceability, programmable parameters, and operational data recording. PLC-controlled double-door industrial ovens have become core equipment for batch heat treatment production. The double-door, large-cavity design effectively expands the internal working space, allowing for the loading of more workpieces at once. Combined with a PLC programmable control system, it achieves multi-stage heating, temperature control, and automatic cooling, reducing manual intervention and improving production efficiency and product yield. Dongguan Hangtong Automation Technology Co., Ltd., with 20 years of experience in the industrial heat treatment field, has independently developed PLC-controlled double-door industrial ovens, providing mature automated baking systems for large-volume curing and drying in various industries.
The Hangtong PLC double-door industrial oven features a wide double-door structure and a large cavity volume, facilitating the entry and exit of trolleys and material trays. It is suitable for processing large workpieces and large batches of materials. The optimized internal hot air circulation duct design ensures uniform hot air circulation throughout the oven, resulting in good temperature uniformity and preventing variations in baking effects due to different workpiece placement positions, thus guaranteeing consistent product quality in large batches. The furnace body features a thickened insulation structure, ensuring strong sealing and low heat loss, resulting in greater energy efficiency for long-term continuous production.
A key highlight is the PLC intelligent control system, paired with a human-machine interface touchscreen. This allows for visualized operation of process parameters, supports editing and storing multi-segment heating-constant-cooling process curves, and can save multiple product process formulas. These formulas can be directly recalled when switching products, eliminating the need for repeated parameter adjustments. The equipment automatically records temperature operating data, supporting data retention and export, meeting production traceability and quality control requirements, making it ideal for manufacturing customers with strict process control. It also features over-temperature audible and visual alarms, fault self-diagnosis, and overload protection, providing timely feedback in case of abnormalities and reducing the risk of production accidents.
The equipment can be equipped with optional modules such as a stainless steel inner liner, explosion-proof components, trolleys, material racks, and forced dehumidification, depending on the customer’s actual working conditions. It is widely used in industries such as new energy components, automotive parts, plastics, metal electroplating, composite materials, and curing of spray-coated workpieces, suitable for batch curing, drying, annealing, and aging testing in factories. Hangtong Automation can provide non-standard customization based on workshop space, production capacity requirements, and process indicators. From solution integration, production, commissioning to delivery, it provides a complete heat treatment solution to global customers, and can deliver stably whether it is domestic factory expansion or foreign trade export orders.
