AI-Powered supplier vetting

SummaryHangzhou Codewel New Material Co., Ltd. is a China-based limited company described as both a trading company and manufacturer/factory, with 10 employees and products including thermal transfer ribbons, adhesive labels, printer heads, and printers. It provides OEM services for well-known brands and customization from samples, but reports no ODM service, no SDK, no private-mold development, no 3D design service, and no new products in the past year. Service procedures exist for supplier service assessment, corrective actions, and complaints, but written records are unavailable. The supplier has no overseas warehouse, showroom, agent, or branch, and has not participated in offline trade shows. Overseas service coverage is listed as zero, although it accepts several quotation and payment terms and reports one-month lead times. Financial information is represented by year labels only, without sufficient performance detail. Sustainability and digitalization statuses are unknown.

Supplier typeThe supplier is identified as both a trading company and manufacturer/factory, legally organized as a limited company. Its listed products cover thermal transfer ribbons, adhesive labels, printer heads, and printers, indicating a mixed manufacturing and trading profile.

After-Sales capabilityThe supplier has procedures for service assessment, corrective and preventive actions, and customer complaints, but no written records are available for these processes. It also has no overseas warehouse, showroom, agent, or branch; overseas service coverage is listed as zero, while stated lead times are one month in both peak and off-season.

R&D capabilityInnovation evidence is limited: the supplier has one R&D engineer and provides customization from samples, but launched no new products in the past year, offers no ODM service, has no SDK, no private-mold capability, and no 3D software design service. It is described as a professional technical supplier, but the stated limitations indicate no demonstrated innovation advantage.

Product Q&A

Q:What are the advantages of Codewel compatible print heads?

1) Ultra-high quality, all accessories are 100% brand new, made in China. 2) Adopt thin film technology and independently develop internal circuit board design. 3) Provide the same warranty as the original print head. 4) With a 20-year experience R&D team in the first-class Rohm company, the quality of the print head can be controlled.

Q:What should I do if the printing density is uneven?

1) Check whether the print head pressure is balanced and adjust the rubber roller pressure. 2) Clean the surface of the print head. 3) Confirm that the ribbon matches the media (such as wax-based, mixed-based or resin-based carbon ribbon).

Q:How often do you need to clean the print head?

1) Regular use: Clean after each roll of ribbon is replaced or at the end of each day's work. 2) High-load use: clean every 2-3 hours. 3) Clean immediately when you find that the print quality has deteriorated.

Q:How to clean the print head correctly?

1) Use a special cleaning pen or non-woven cloth to dip in a small amount of isopropyl alcohol (do not use water or alcohol). 2) Gently wipe the surface of the print head in the same direction to avoid scratches. After cleaning, wait for it to dry completely before turning on the machine.

Q:How long is the life of the print head?

Depending on the frequency of use, media type and maintenance, it is generally 30-50 km in length, and some industrial print heads can print up to 100 km in length.
