AI-Powered supplier vetting

SummaryDongguan Hongjun Packaging Technology Co., Ltd. is a China-based manufacturer/factory in Dongguan, Guangdong, focused on intelligent web guiding systems, automatic tension systems, air shafts, rollers, and related packaging and printing machinery components. The supplier explicitly reports R&D capability as a professional technical supplier, provides after-sales service, and offers multiple forms of customization. It does not provide 3D software design services and has no available SDK. Export sales account for 90%, and it began exporting four years ago. The available information does not establish certifications, financial strength, customer cases, raw-material traceability, or environmental and fire-drill compliance. The stated employee count is four, which provides limited evidence regarding production scale but does not by itself prove inadequate manufacturing capability.

Supplier typeThe supplier is identified as Dongguan Hongjun Packaging Technology Co., Ltd., a China-based limited company and manufacturer/factory. Its stated business covers R&D, production, sales, and after-sales service for tension and correction control solutions and related machine components.

After-Sales capabilityThe company explicitly states that it provides after-sales service for intelligent correction systems, automatic tensioning systems, sliding shafts, pneumatic shafts, and related products. This directly supports an after-sales service capability for its product range.

R&D capabilityThe supplier is explicitly described as having professional technical R&D capability and conducts R&D for intelligent correction and automatic tensioning systems. However, it does not provide 3D software design services and has no available SDK; therefore, the evidence supports product-oriented R&D but not broader software or integration capability.

Production capacityThe supplier identifies itself as a manufacturer/factory and states that it undertakes production of air shafts, web-guiding and tension-control products, rollers, and related components. Its stated employee count is four, indicating a small disclosed workforce, but the slices do not establish production capacity, equipment, or delivery performance.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. These multiple stated service modes provide direct evidence of broad customization capability.

Product Q&A

Q:What are the customization options for this air shaft?

Q:What is the expansion performance of the leaf type air shaft?

The expansion height typically reaches 4mm to 5mm. For example, a 74mm-74.5mm diameter shaft can expand to 78mm-79mm. The fulcrums are evenly dispersed to ensure uniform force distribution.

Q:Which industries or materials is this air shaft suitable for?

It is ideal for machinery requiring high winding precision or handling light items, such as electronic materials, battery materials, foaming, cotton, plush, paper towels, and non-woven fabrics.

Q:When should I use a slatted air shaft instead of a standard one?

Use a slatted air shaft when: a) winding narrow strips; b) requiring a higher true circle; c) the paper core has a thin wall or poor quality and deforms easily.

Q:What is the MOQ and lead time for orders?

The Minimum Order Quantity (MOQ) is 1 piece. The lead time is 13-15 days after receiving the deposit.
