Screen Printing Tunnel Oven

To achieve successful screen printing curing, a fine balance between heating and air exchange is required. Dingfeng's Screen Printing Tunnel Oven Made in China is equipped with an integrated volatile organic compound management system. It features a 200-watt high-temperature centrifugal fan and a self-developed 9-inch stainless steel diffuser, which can effectively capture and discharge solvent vapors, preventing them from re-aggregating before reattaching to the substrate. This can prevent the "ink fog" and "ghost images" along the entire conveyor belt width.

Basic parameters

Configure safety performance

To ensure the safety of operators, the furnace cover of the Screen Printing Tunnel Oven is equipped with an innovative 6000N high-strength electric cylinder, which provides a 350mm top clearance, facilitating internal maintenance work. At the same time, hardened nickel-plated safety rails are integrated, along with an electronic mechanical interlock device, which can prevent accidental closure and synchronize with the heating system. Opening the furnace cover will automatically cut off the 24-kilowatt power array. This level of safety compliance follows ISO and OSHA workplace standards.

Our advantages

Maintaining the environmental temperature of the clean room is just as important as the curing process itself. The Screen Printing Tunnel Oven uses a 1.2-ton mirror-finish stainless steel 304 internal structure, which is crafted through a full argon arc welding process to ensure a dust-free and particle-free environment. To minimize the heat load on the workshop, 120K high-density insulation materials are used, along with a dedicated internal air insulation layer. This ensures that the outer shell feels very cool, reducing the heat load of the facility's air conditioning system and increasing the overall energy investment return rate.

Q&A

Q1: How does the "inward-outward" infrared curing technology enhance scratch resistance?

Answer: When the ink starts to cure from the bottom, it forms stronger chemical bonds with the substrate. Standard hot air may cause the bottom of the ink layer to become slightly soft, resulting in poor adhesion. However, our mid-wave infrared emitter ensures that the entire ink layer reaches the glass transition temperature simultaneously, thus creating a harder and more scratch-resistant surface.

Q2: Can the exhaust rate be synchronized with the use of ink with high solvent content?

Answer: Yes. Dingfeng's oven has adjustable stainless steel air valves. Your operators can adjust the emission rate of volatile organic compounds according to the solvent content of the ink. This ensures that even in high-density printing processes, the environment remains unsaturated, promoting rapid evaporation and preventing color changes caused by solvents.

Q3: Is the electric lifting system compatible with the high-frequency cleaning plan?

Answer: Of course. Our 6000N electric pusher has a long industrial lifespan. The one-click lifting mechanism, combined with the mirror-finished SUS internal structure, can complete the wiping of the entire chamber in just a few minutes. This minimizes maintenance downtime and ensures that the certified printing environment requires only a little effort to maintain a perfect state.

Question 4: How can we prevent thin sheet materials like polyester/polyvinyl chloride from deforming at temperatures above 100°C?

Answer: Thermal deformation is usually caused by uneven thermal stress. First, our pressurized exhaust system acts as an air clamp, keeping the film flat against the mesh belt. Secondly, the controllable SCR current control can achieve extremely smooth temperature rise, avoiding sudden thermal shocks that cause thin-gauge plastics to contract or curl.

Question 5: Can this oven handle high-solvent, odor-causing inks without contaminating the workshop?

Answer: Of course. We have designed a set of volatile organic compound (VOC) extraction system that meets the Ames standard. By installing a 200-watt high static pressure fan and adjustable stainless steel air valves, our system maintains a negative pressure environment inside the heating chamber. This ensures that 95% of the solvent vapor is captured and directed to the factory's central exhaust pipe, keeping your cleanroom air fresh and in compliance with environmental standards.

Question 6: Can the height of the infrared lamps be adjusted to accommodate different product shapes?

Answer: Yes. We understand that screen printing products may vary from flat sheets to 3D electronic shells and other shapes. The infrared array is installed on a track system with adjustable height.

Question 7: How much energy can the dual-function insulation actually save for me?

Answer: Compared to a standard single-layer insulated oven, the dual-function insulation barrier (120K asbestos + internal air gap) can reduce surface heat radiation by approximately 20% to 25%.

Question 8: What is the maximum conveyor belt width available for large-format printing?

Answer: Although our Screen Printing Tunnel Oven is optimized for common industrial sizes, our 11,000 square meter manufacturing facility allows for complete customization. We have successfully provided custom specifications with a maximum width of 1750 millimeters for large-sized display screens and automotive trim printing, while always maintaining a strict consistency standard of ±5°C.

Question 9: Does the 90-day data record meet the requirements of medical-grade printing?

Answer: Yes. Our Weinview HMI can record temperature in real time.
