The COHE-1802 Socks Oven is a key ancillary finishing device in Ningbo Colorido's digital printing solutions, built for the heat-fixation process of polyester socks after digital printing. With an extended chain conveyor, continuous circulating air heating, 30KW power and 18 heating tubes, it keeps cavity temperature uniform and stable so disperse ink fully fixes onto polyester fibers for vivid, durable prints — and its 6-meter rail can be customized to your production line.
A long-chain conveyor structure with increased motor power lets the drag-chain length be customized to your line, adapting to different capacities and sites.
Heated air circulates continuously inside the cavity, distributing temperature evenly and avoiding uneven fixation caused by temperature gradients.
High-power efficient heating with 18 heating tubes delivers fast heat-up and a constant cavity temperature, with a maximum working temperature of 190±2°C.
Outer shell, inner layer and frame are all premium 1.5-SUS208 stainless steel plate — heat- and corrosion-resistant for long-term high-temperature operation.
The COHE-1802 Socks Oven adopts an extended chain conveyor and a continuous circulating hot-air heating process with an all-stainless-steel inner chamber, designed specifically for heat fixation of polyester socks after digital printing. The outer shell, inner layer and frame are all premium 1.5-SUS208 stainless steel plate, while 30KW heating power with 18 heating tubes keeps the cavity at a stable, uniform temperature up to 190±2°C for vivid and durable prints.
As a downstream ancillary device on the Ningbo Colorido sock-printer production line, the COHE-1802 pairs with printers such as the CO80-210PRO, CO60-100PRO and CO80-600DK. After printing, socks are hung directly onto the stainless-steel needles of the drag chain, which feeds them into the oven body for heating and fixation — completing the continuous print — dry — fix workflow. The standard external rail is 6 meters and can be customized to capacity and site requirements, adapting to production lines of different scales.

Six core capabilities that bring continuous, uniform polyester sock heat fixation to large-scale printing production lines.
Adopts a long-chain conveyor structure; by increasing motor power the drag-chain length can be customized to your production-line needs, adapting to different capacities and sites for continuous print — dry — fix production.
The outer shell, inner layer and frame are all premium 1.5-SUS208 stainless steel plate — heat-resistant and corrosion-resistant for long-term high-temperature operation and an extended equipment service life.
30KW heating power with 18 heating tubes delivers fast heat-up and a constant cavity temperature, with a maximum working temperature of 190±2°C for full fixation of polyester disperse ink.
Controlled by an LED digital display (AISET ND6000) with dual PV/SV display; temperature and time can be adjusted as needed, with parameters clearly visible for precise and intuitive control.
Equipped with a 0.75kW circulation fan (60Hz, 220V) to keep the temperature difference inside the oven to a minimum; a gear drives the drag chain so socks are heated consistently for uniform fixation.
Both the drag-chain length and the equipment dimensions can be customized — the standard external rail is 6 meters — to fit different capacities and production-line layouts.
From the drag-chain conveyor to the 18-tube heating system, every component is built for continuous, uniform polyester heat fixation on the production line.
The oven’s drag chain is equipped with stainless-steel needles (hooks), which are durable and do not damage the socks when hanging. Once printing is finished, socks are hung directly onto the stainless-steel needles and the drag chain automatically feeds them into the oven body for heating and fixation, enabling automated loading and unloading and preventing printed socks from staining each other during drying.
The oven is equipped with a temperature-regulating fan (circulation fan, 0.75kW, 60Hz, 220V) to keep the temperature difference inside the oven to a minimum and ensure uniform temperature. A gear drives the drag chain so that the socks are heated consistently during conveyance, improving fixation uniformity across the whole batch.
The oven is controlled by an LED digital display (AISET ND6000 temperature controller) with dual PV (process value) and SV (set value) displays. Temperature and time can be adjusted as needed, with a maximum temperature of 190±2°C. Operation is intuitive and parameters are clearly visible, making it easy to set fixation parameters according to fabric and ink process.
The oven’s drag chain uses a roller chain with bent attachments; the chain length can be adjusted to the production-line requirements. Together with the customizable external rail (standard 6 meters), it adapts to continuous production of different scales, letting you match capacity and site layout precisely.
The oven is equipped with 18 heating tubes, offering fast heating speed and a more constant cavity temperature. Combined with 30KW heating power and the continuous circulating air duct, it achieves fast heat-up and stable temperature control, ensuring full fixation of polyester disperse ink for vivid and durable print results.
The complete polyester sock manufacturing process — from digital printing through oven heat fixation on the extended-chain conveyor line.
Production Director · Heartland Custom Socks, USA
We run the COHE-1802 inline with our CO80-210PRO and the extended drag chain feeds printed socks straight from the printer into fixation without a single manual hand-off. Ningbo Colorido built the rail to our exact six-meter floor plan, and the continuous print — dry — fix flow lifted our daily output far beyond what batch ovens ever delivered.
Plant Manager · Bayerwald Textilwerk, Germany
Running three shifts a day demands a machine that holds temperature. The COHE-1802’s full SUS208 stainless structure and eighteen heating tubes keep the cavity at a steady 190±2°C shift after shift, and after a year of continuous use the chamber still shows zero corrosion — the build quality is exactly what our audit checklist required.
Operations Head · Mysore Sock Mills, India
The 30KW heating power means the COHE-1802 reaches working temperature far faster than our old unit, so we lose almost no time between changeovers. Paired with our CO80-600DK, socks come off the printer and hang straight onto the stainless hooks — the whole polyester workflow is now one smooth, labour-saving line.
Factory Owner · Calcetines del Bajío, Mexico
Our retail customers kept rejecting orders for poor colourfastness. Since fixing disperse ink in the COHE-1802 with its circulating hot air, every wash test passes first time and the colours stay vivid run after run. The continuous chain output let us take on bulk orders we simply could not fulfil before.
QA Engineer · Ipek Corap, Turkey
The LED PV/SV display lets our operators set and verify fixation parameters precisely for each fabric and ink, and the temperature-regulating fan keeps the heat so uniform that batch-to-batch colour variation has all but disappeared. For a QA team that lives and dies by consistency, the COHE-1802 is exactly the control we needed.

Under normal use, the machine basically does not break down. It is recommended to lubricate the gears regularly to extend service life and maintain stable operation.
Become our customer and our products come with a lifetime warranty.
We have a dedicated installation video for you, and we can also support online installation guidance to help customers complete equipment installation and commissioning.
Lubricate the gears regularly. In daily use, operate per the instructions: raise the baffle during heat-up for a faster temperature rise, and lower it once the set temperature is reached to keep the temperature constant.
The COHE-1802 adopts a continuous circulating air heating method. Through the air duct and circulation fan, heated air continuously circulates inside the cavity, making the temperature distribution uniform and avoiding uneven fixation caused by temperature gradients. Combined with 18 heating tubes and 30KW power, it heats up quickly with a constant temperature.
When heating up, raise the baffle so the temperature rises faster; once the temperature reaches a suitable level, lower the baffle to keep it more constant. Adjust the speed according to sock thickness — the thicker the socks, the longer the drying time. When drying pure white socks, wait for them to cool before taking them off to prevent staining from excessive temperature.
