SummaryWeihai Zhonghao Pneumatic Complete Equipment Co., Ltd. is presented as an integrated pneumatic and hydraulic equipment supplier covering R&D, production, sales and after-sales service. It identifies itself as a professional technical supplier offering 3D software design and sample-, design-, and fully customized services. The company reports more than 15 years of industry experience and operation since 2007, along with ISO9001, CE and SGS-related certifications or reports. Evidence supports responsive technical and after-sales assistance, inventory capability, valid manufacturing contracts with associated subcontractors, and structured supplier-service procedures. However, it reported no new products during the past year, has no overseas warehouse or showroom, and provides no direct evidence of customer cases or financial credibility. Finished-product inspection instructions exist, but written inspection records are not maintained.

Supplier typeThe supplier is explicitly described as a professional technical supplier and as an integrated enterprise covering R&D, production, sales and after-sales service for pneumatic and hydraulic components. Its stated business scope also includes electronic, electromechanical, plastic, rubber and related equipment products.

CertificationsThe company states that it holds ISO9001 and CE certifications and has SGS reports to enhance product credibility. This is explicit evidence of certification-related holdings, although the slices do not provide certificate validity dates or detailed scopes.

After-Sales capabilityThe supplier describes pre-sales, in-sales and after-sales support through on-site service, video guidance and phone assistance, supported by senior technical engineers handling installation, commissioning and fault diagnosis. It also reports inventory capability, but lacks overseas warehouse and showroom capability.

Production capacityThe supplier presents itself as a manufacturer with production capabilities, valid contracts with each related subcontractor, inventory capability, and documented service-capability procedures with records. Finished-product inspection instructions exist but lack written records, which limits evidence of production-quality control execution.

Its technical team is also described as experienced in product design and production technology, supporting tailored solutions.
