How long does it take to deal with the problem found after receiving the goods?

Respond within 2 hours after receiving feedback, and provide solutions within 24 hours.

What should be done if product quality is non-compliant?

If nonconformity in size, material, or flaw detection results from our party's fault, we will provide unconditional rework, remake, or refund.

What is the payment method?

A standard procedure requires a 30% deposit upfront, with the remaining balance payable before shipment. Existing customers may negotiate payment terms.

Can the size be modified during production?

Adjustments are possible before material cutting, but once forging is completed, modifications cannot be made. Please confirm the drawings before placing the order.

AI-Powered supplier vetting

SummaryThe supplier is a combined company engaged in metal manufacturing, forging, casting, machinery, and related material sales. It demonstrates documented procedures for corrective and preventive actions, customer complaints, and finished-product inspection, and states that it provides quality assurance. The supplier offers broad customization, including sample-, design-, full-, minor-, and flexible customization, as well as 3D software design services. Its production-related scope covers forgings, flanges, pressure pipeline components, metal-processing machinery, foundry machinery, and high-performance metal materials. However, the supplied information shows no valid manufacturing-capacity contract with an affiliated subcontractor, no overseas warehouse, overseas showroom, overseas agents or branches, or offline trade-show participation. Financial credibility, certifications, and customer cases cannot be adequately assessed from the provided slices.

Supplier typeThe supplier is identified as a combined company with business activities spanning parts manufacturing, metal-processing machinery, forging, powder metallurgy, casting, metal materials, and related equipment sales. This indicates a manufacturer and supplier with a broad industrial product scope rather than a narrowly defined trading-only entity.

After-Sales capabilityThe supplier has clear procedures and follow-up records for corrective and preventive actions and customer complaints, indicating a documented service-management process. It also has in-stock service capability, but lacks overseas warehouses, overseas showrooms, overseas agents or branches, and documented overseas service coverage, limiting evidence of geographically extensive after-sales support.

R&D capabilityThe supplier identifies itself as a professional technical supplier and provides 3D software design services, supporting some technical-development capability. However, it reports no available SDK, and the slices provide no measurable R&D investment, patent, or completed innovation-project evidence.

Production capacityThe supplier describes manufacturing and processing of free forgings, flanges, and pressure-pipeline components, while its registered scope includes forging, powder metallurgy, casting, machinery, metal processing, and non-ferrous alloy materials. It also has a stated in-stock service capability and standardized finished-product inspection instructions, supporting substantive production capability.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also provides 3D software design services, indicating broad adaptation of products or designs to customer requirements.

Product Q&A

Q:Are your forgings forged or cast/welded?

All parts are forged as a single unit without welds or porosity, exhibiting significantly higher strength compared to cast steel components and welded parts.

Q:What should be done if the goods are damaged?

On-site inspection and photography upon delivery, with free repair or remake confirmed if transportation-related issues are identified, and full responsibility throughout the entire process.

Q:What are the commonly used materials?

Carbon steel, alloy steel, stainless steel, duplex steel, mold steel, nickel-based alloy, etc.

Q:Can you provide flaw detection and material reports?

UT/MT/PT flaw detection report, material list, heat treatment report, certificate of conformity can be provided, and a full set of goods are available.

Q:How long is the lead time?

10-15 days for regular parts, 25-30 days for customized large items, and urgent orders can be arranged first.
