AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier with activities covering technology development, consulting, transfer, promotion, electronic and electromechanical products, mechanical equipment and components, and technology import and export. It provides multiple forms of customization and has R&D capability with an available SDK, but does not provide 3D software design services. Quality and service processes are supported by written procedures, records, traceability, and quality assurance. Manufacturing capacity is contractually supported with associated subcontractors, while stockholding, overseas warehouses, overseas showrooms, overseas agents or branches, and offline trade-show participation are unavailable. Export experience is stated as 19 years, with exports representing 51%–70% of total sales.

Supplier typeThe supplier explicitly identifies itself as a professional technical supplier. Its stated business scope includes technology development, consulting, exchange, transfer, promotion, technical services, R&D, and sales of electronic, mechanical, and electromechanical products.

CertificationsThe supplier holds an ISO9001:2015 certificate and reports quality assurance, raw-material traceability, and documented corrective and preventive action procedures. The slices do not specify the certification scope or validity details.

After-Sales capabilityThe supplier has documented procedures and records for handling customer complaints and corrective/preventive actions, and accepts FOB, CIF, CFR, and EXW quotation terms. However, it has no overseas agents or branches, no overseas warehouse, and offers services in zero stated countries, limiting evidence of localized overseas after-sales coverage.

R&D capabilityThe supplier has professional technical R&D capability, an available SDK, and stated R&D activities in household appliances and efficient energy-saving power technologies. It does not provide 3D software design services, but this limitation does not negate the documented technical R&D capabilities.

Production capacityManufacturing capacity is supported by valid contracts between the factory and each associated subcontractor, with standardized finished-product inspection instructions, quality assurance, traceability, and documented supplier-management procedures. The supplier has no in-stock capacity, so immediate inventory fulfillment is not supported.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. These repeated descriptions provide direct evidence of broad customization capability, although 3D software design services are specifically unavailable.

Product Q&A

Q:What is the delivery time?

20-30 days.

Q:What is the warranty period for products?

All products are with 1 year guarantee.

Q:Are the PCBA products standardized for all heat pumps?

Nope, since the logic and the structure for different brands of heat pump are diverse, the PCBA products are not standardlized. We need to customized for every customer.

Q:What is the process to cooperate with ASL?

We undertake the following SOP to provide customer serviese: (1)technical communicate for: the usage scenarios, the heat pump functions, the voltage and power required, the compressor's brand and type (2)ASL provide our suggestion for the appropriate combo list for the whole heat pump solution and the quotation (3)place the sample pieces order (4)Detail technical design for software and hardware (5) Logic confirmation from customers (6)ASL produce and deliver the sample pieces (7) sample confirm

Q:What is the annual production capacity?

Annually production of DC inverter PCBA reached 30w+.
