    What Makes the COHE-1801 the Right Sock Heating Oven for Polyester Fixation?

    The COHE-1801 is a sock heating oven designed for the heat-fixation process of polyester socks after digital printing. With 15KW heating power and 18 stainless-steel heating tubes, it uses continuous circulating air heating to ensure uniform cavity temperature so that disperse ink fully fixes onto polyester fibers for vivid and durable print results.

    • Continuous circulating air heating

      Temperature distribution inside the cavity is more uniform and heating more stable, avoiding uneven fixation caused by hot spots or temperature gradients.

    • All-stainless-steel structure

      Outer shell, inner layer and frame are all made of premium 1.5-SUS208 stainless steel plate, offering high-temperature and corrosion resistance.

    • ±1℃ temperature-control accuracy

      Rapid heat-up with stable temperature maintenance; PID adjustment via a Shanghai Yatai high-precision digital display temperature controller.

    • 450 pairs/hour batch output

      Accommodates 22.5 pairs of socks at a time; a single oven can support around 8–9 sock printers for batch production.

    New Sock Heating Oven COHE-1801

    The COHE-1801 sock heating oven adopts a continuous circulating hot-air heating process, designed specifically for heat fixation of polyester tubular products (socks, wristbands, headbands, etc.) after digital printing. Its all-stainless-steel body and 100mm insulation layer ensure stable cavity temperature and energy-efficient operation.

    As a downstream ancillary device on the Ningbo Colorido sock-printer production line, the COHE-1801 can be paired with multiple sock printers such as the CO80-210PRO, CO60-100PRO and CO80-600DK. Once printing is finished, socks can be hung directly onto the oven's conveyer chain, which automatically sends them into the oven body for heating and fixation, completing the polyester sock printing workflow.

    Conveyer Chain

    Ningbo Colorido sock oven uses a conveyer chain system to avoid any printed socks getting ink stains during the drying process. There are 45 hooks in one circle, and the installation method is convenient. Once printing is finished, socks can be hung directly onto the conveyer chain, which automatically sends them into the oven body for heating and fixation, enabling automated loading and unloading.

    • No ink staining: Conveyer chain keeps printed socks separated during drying.
    • Automated workflow: 45 hooks per circle enable hands-free loading and unloading from the sock printer.

    COHE-1801 Questions, Answered

    Common questions about polyester sock heat fixation, heating method, capacity, power and pricing — then send your requirements for a configuration recommendation.

    The COHE-1801 is a high-temperature heat-fixation device for polyester socks and other tubular products after digital printing, used to fully fix disperse ink onto polyester fibers and improve print fastness and color reproduction. It is typically used as a downstream ancillary device on the Ningbo Colorido sock-printer production line. Once printing is finished, socks can be hung directly onto the conveyer chain, which automatically sends them into the oven body for heating and fixation.

    The COHE-1801 adopts a continuous circulating air heating method. Through the duct and motor, heated air continuously circulates inside the cavity, making the temperature distribution more uniform and heating more stable, avoiding uneven fixation caused by hot spots or temperature gradients. Temperature-control accuracy reaches ±1℃, and cavity temperature uniformity ±5℃.

    The COHE-1801 is designed specifically for polyester tubular products such as polyester socks, wristbands, headbands, sport sock sleeves, and knit beanies. For non-polyester materials or other ink systems, compatibility must be separately confirmed rather than directly applying polyester disperse-ink process parameters.

    The temperature is adjustable. The specific fixation temperature and time should be determined by sample testing based on fabric type, ink model, print coverage, and garment load. Universal parameters must not be applied. After fixation, color, fastness, print appearance, and dimensional stability should be inspected.

    The COHE-1801 uses a 3-phase 380V/240V (optional) industrial power supply with 15KW heating power and 24V control-circuit voltage. Before installation, qualified electrical personnel must confirm that the factory's electrical configuration meets the requirements and connect the supply per code. The equipment is equipped with leakage protection, circuit breaker protection, and grounding protection.

    The outer shell, inner layer, and frame are all made of premium 1.5-SUS208 stainless steel plate, offering high-temperature and corrosion resistance for long-term high-temperature operation. The insulation layer uses 100mm-thick stainless steel with 100K high-density aluminum silicate fiber filling, effectively reducing heat loss. The main body dimensions are 1400×1050×1800 mm and weight 450 kg; the structure is compact and rationally laid out.

    The oven accommodates 22.5 pairs of socks at a time, with output of approximately 450 pairs/hour (calculated at 3 minutes per turn). Actual output varies with sock thickness. A single oven can support around 8–9 sock printers. For larger-capacity sock heating needs, custom larger-capacity ovens can be built.

    The COHE-1801 is an ancillary finishing device on the digital-printing production line, typically paired with Ningbo Colorido sock printers (CO80-210PRO, CO60-100PRO, CO80-600DK, etc.) to build a complete print—dry—fix workflow. If used independently for other high-temperature processes, compatibility must be separately assessed.

    Ningbo Colorido must confirm the applicable product range, fabric and ink process, fixation-parameter requirements, electrical configuration, installation site, ventilation/heat discharge, packing, destination, training, service, and sample criteria. Price, lead time, warranty, and installation conditions should be stated in the current written proposal rather than treated as permanent website promises.
