The supplier reports ISO 9001 and ISO 14001 certifications, 24/7 technical and spare-parts support, and R&D engineering experience of 31–40 years in aggregate. It claims customization-oriented product recommendations and applications across several industrial sectors. However, the available trade record shows only one transaction and does not establish a broad customer-case history. Financial credibility cannot be assessed because financial information is excluded.
Supplier typeThe supplier is identified as a trading company and manufacturer/factory, legally organized as a limited company in Jiangsu, China. Its stated business covers industrial equipment and manufacturing machinery, with product keywords centered on rolling, bending, and sheet-metal forming machines.
CertificationsThe supplier explicitly reports ISO 9001:2008 international quality-system certification and ISO 14001 and ISO 9001 management-system certifications. These statements provide direct evidence of certification holding, although the slices do not provide certificate numbers, validity dates, or issuing-body details.
After-Sales capabilityThe supplier states that it provides 24/7 free-call technical support and comprehensive, consistent technical and spare-parts service after sales. It also claims quality testing before delivery, directly indicating a defined after-sales support commitment.
R&D capabilityThe supplier states that Huaxi Machinery began production in 2002 and focuses on R&D and manufacturing of sheet-metal forming machinery, while the reported total experience of R&D engineers is 31–40 years. These statements support established R&D capability, though they do not document specific patents, new product launches, or measurable innovation outcomes.
Production capacityThe supplier describes machining equipment including large-scale lathes, boring, drilling, milling, and welding machines, and reports annual productivity of 2,000 sheet-metal machine sets. It also states a peak-season fulfillment time of 2–3 months and production of multiple machine categories, supporting a documented production base.
Customization capabilityThe supplier states that it introduces suitable products according to customer requests and provides solutions across multiple machine types, including three- and four-roll bending machines, angle rolls, laser cutting machines, and press brakes. Its description of CNC equipment handling complex, fine, small-batch, and varied parts further supports flexibility, although no specific customized project is documented.
Product Q&A
Q:How long is the service life of the machine?
A:
It depends on worker skills, experience, and daily working hours. With normal maintenance under instructions, the life can reach up to 10 years. Working 12 hours or more daily may affect service life.
Q:What types of rolling machines do you offer?
A:
We offer three main kinds: Mechanical 3 roller, hydraulic 3 roller with prebending, and hydraulic 4 roller with pre-bending.
Q:What are the specifications and customization options?
A:
We have light and heavy types with thickness from 6-150mm and width 1000-12000mm. We can make special machines per customer request, such as smaller rolling diameter or special applications like oil pipes or wind towers.
Q:Can the machine handle hot forming?
A:
Yes, we custom roll form cylinders cold typically, but we have the ability to hot form as required to prevent material fracture due to high thickness-to-diameter ratios.
Q:What materials can this machine process?
A:
The CNC hydraulic double pre-bending rolling machines can work with carbon steel, stainless steel, aluminum, and most plate materials.
