AI-Powered supplier vetting

SummaryWeifang Lulin Machinery Co., Ltd. is described as a high-tech enterprise founded in 1986, with a 28,547.0 m² manufacturing plant and capabilities covering ductile iron fittings, valves, machinery parts, OEM castings, and related metal products. Evidence indicates established quality, corrective-action, complaint-handling, and finished-product inspection procedures, along with ISO9001, ISO14001, and ISO45001 certifications and UL-related product certification capability. The supplier supports extensive customization, OEM services for popular brands, and operates equipment including spectrometers, tensile testers, CNC machines, furnaces, machining, packing, casting-related, spraying, leak-testing, and aging-test equipment. However, it has no SDK, no overseas warehouse, overseas showroom, overseas agent or branch, or valid manufacturing-capacity contract with affiliated subcontractors. Financial and cash-flow records are referenced for 2023–2025, but no assessable financial results are provided.

Supplier typeThe supplier is identified as Weifang Lulin Machinery Co., Ltd., founded in 1986, with a stated 28,547.0 m² manufacturing plant and business scope covering mechanical parts, automotive parts, plumbing and construction metal products, and safety and fire-protection metal products. However, the company nature is also recorded as a trading company and the entity type as combined, so the available records indicate a mixed manufacturing and trading profile rather than a purely defined manufacturer.

CertificationsThe supplier reports ISO45001:2018, ISO9001:2015, and ISO14001 certifications, plus UL and other product-certification capability. These explicit certifications support its quality, environmental, occupational-safety, and product-compliance credentials.

After-Sales capabilityThe supplier has clear procedures and followed records for corrective and preventive actions and customer-complaint handling, and it reports in-stock service capability. However, it has no overseas warehouse, overseas showroom, overseas agents or branches, and lists zero countries for overseas service coverage, limiting its demonstrated international service reach.

Production capacityProduction capability is supported by the stated 28,547.0 m² plant and a broad equipment set including spectrometry, tensile testing, CNC machining, medium-frequency furnace, lathe, packing, sand mixing, spraying, tapping, air-tightness testing, and aging testing. Finished-product inspection instructions are reportedly uniformly followed, and in-stock service capability is available. A deficiency remains in the absence of a valid manufacturing-capacity contract with affiliated subcontractors.

Customization capabilityThe supplier explicitly supports flexible customization, minor customization, customization from customer designs, customization from samples, and full customization. Its stated product scope includes ductile iron fittings, valves, machinery parts, and OEM castings, providing direct evidence of broad customized manufacturing capability.
