How is the vibration simulated?

Broadband random vibration is simulated by sub-band approximation. Each sub-band contains a main natural frequency and satisfies the power spectrum of the sub-band vibration magnitude.

AI-Powered supplier vetting

SummaryThe supplier is identified as a manufacturing factory in Dongguan, with manufacturing-related associated companies and a combined company structure. It provides 3D design, OEM, ODM, and multiple customization options, but reported no new products in the past year and has no SDK. Production support includes valid contracts with associated subcontractors, 12 qualified service-capability suppliers, documented assessment procedures, and stated lead times of within 15 working days in both peak and off-season; another record states peak-season order fulfillment takes one month. Quality controls include random finished-product inspection, two QA/QC inspectors, standardized inspection instructions, CE certification, and ISO 9001:2015. The supplier has export sales, but no inventory, overseas warehouse, overseas showroom, overseas agents or branches, or offline trade-show participation. Financial credibility cannot be determined from the non-financial evidence provided.

Supplier typeThe supplier is explicitly identified as a factory located in Dongguan, while its associated companies are in manufacturing and the company type is recorded as combined. This supports classification as a manufacturing-oriented supplier rather than a purely trading entity.

CertificationsThe supplier holds CE certification for product compliance and an ISO 9001:2015 management-system certificate. It also reports an environmental impact assessment report and fire-drill activity, providing direct evidence of product, quality-management, and selected sustainability-related credentials.

Production capacityThe supplier has valid manufacturing-capacity contracts with each associated subcontractor, lists 12 qualified service-capability suppliers, maintains written assessment procedures and records, and reports lead times within 15 working days in both seasons. Its facility includes lathes, milling machines, and threading machines; however, a separate record states peak-season fulfillment takes one month, creating inconsistent lead-time evidence.

Customization capabilityThe supplier explicitly offers customization from samples, full customization, minor customization, flexible customization, and customization from designs. It also provides 3D design services and ODM/OEM services, directly supporting a broad customization offering.

Client casesThe supplier states that it provides OEM services for well-known brands, which is direct evidence of brand-customer experience. No specific customer names, projects, volumes, or independently verifiable case details are provided.

Product Q&A

Q:What is the delivery time?

We usually have stock in the factory. If out of stock, delivery takes 7-20 working days after receiving the deposit. For urgent needs, special arrangements can be made.

Q:What standards does the test bench meet?

The test bench meets the QJ815.2 Standard of the Ministry of Aerospace Industry of the People's Republic China, which covers requirements and methods for the accelerated simulation test of product road transport.

Q:What is the maximum weight capacity?

The maximum weight of the test object, including fastening fixtures, is 500kg. The machine's max capacity is under 1000KN.

Q:What types of road conditions can be simulated?

It simulates third-class highway intermediate pavement, fourth-class highway intermediate pavement, and low-level pavement. Speeds include 35Km/h for medium-level roads and 25Km/h for low-grade roads.

Q:What is the working surface size?

The working surface size is 2000X1400mm. The overall dimensions are 2000X1400X1000mm.
