Qingdao Damuyuan Machinery Manufacturing Co., Ltd. Supplier Evaluation
Executive Summary
Qingdao Damuyuan Machinery Manufacturing Co., Ltd. is a China-based supplier located in Shandong, focused on aluminum axial fan impellers and industrial axial flow fan products. The supplier shows a relatively solid platform profile, with 3 years as an Gold Supplier, Trade Assurance support, verified supplier status, and platform labels including Finished Product Inspection, ODM service, Full Customization, and Warranty available. Its factory area of 8,100+ m2 indicates a meaningful production footprint, although the reported workforce of only 10+ staff limits the visible evidence of large-scale operational capacity. Business performance appears stable, supported by 40+ orders and CN¥3M+ transaction value over the past six months, combined with a strong 4.9 store rating. However, the review count is limited at 10, and the on-time delivery rate of 83.3% indicates acceptable but not excellent delivery reliability. This supplier is most suitable for buyers seeking customized or low-MOQ aluminum axial fan components with moderate procurement risk.

Detailed Analysis
1. Company Strength
Basis:
- Factory location: Shandong, China
- Factory area: 8,100+ m2
- Employees: 10+ staff
- Verified supplier: True
- Main listed products include aluminum axial fan impellers and industrial axial flow fan products
Elaboration:
The supplier has a relatively sizeable factory area, which suggests the availability of physical production space for machinery manufacturing activities. The listed product range is concentrated around aluminum axial fan impellers and axial flow fan products, indicating a focused product category rather than a highly diversified industrial portfolio. The verified supplier status adds credibility to the factory profile. However, the reported employee count of 10+ staff is relatively small compared with the factory area, so the available data does not fully demonstrate large-scale staffing, production line depth, or high-volume manufacturing capability.
Scoring Rationale:
The company demonstrates a basic-to-medium production foundation through its 8,100+ m2 facility and verified supplier status. However, the limited workforce data prevents it from being classified as a large-scale stable supply chain. There is also insufficient data on annual production capacity, equipment quantity, factory audit details, or formal factory certifications beyond supplier verification.
Final Score: 14 / 20
2. Platform & Compliance Credibility
Basis:
- Gold Supplier: True
- Gold Supplier tenure: 3 years
- Trade Assurance: True
- Certification / industry labels: Warranty available, Finished Product Inspection, ODM service available, Full customization
- Verified supplier: True
Elaboration:
The supplier has several important platform credibility indicators. A 3-year Gold Supplier history provides some operating continuity, while Trade Assurance improves transaction security for buyers. The presence of Finished Product Inspection and customization-related labels also strengthens the supplier’s platform profile. However, 3 years is not a long platform history compared with more established long-tenure suppliers, and no independent international certifications or specific compliance certificates are provided in the data.
Scoring Rationale:
The supplier has the core platform trust elements: Gold Supplier status, Trade Assurance, supplier verification, and relevant service/quality labels. This supports a solid credibility rating. The score is not higher because the Gold Supplier duration is moderate rather than long-term, and there is insufficient data on third-party factory certifications, ISO certification, product compliance certificates, or export compliance records.
Final Score: 16 / 20
3. Business Performance
Basis:
- Orders in the past 6 months: 40+
- Transaction value in the past 6 months: CN¥3M+
- Store rating: 4.9
- Review count: 10
Elaboration:
The supplier’s six-month transaction value of CN¥3M+ indicates meaningful commercial activity. The 40+ order count shows that the supplier has recent transaction records rather than being commercially inactive. A 4.9 store rating is strong and suggests positive buyer satisfaction among available reviewers. However, the review count is only 10, which limits the statistical confidence of the rating and makes customer feedback less representative.
Scoring Rationale:
Business performance is above basic level due to the combination of recent orders, significant transaction value, and a high store rating. The score is moderated because the order volume is not exceptionally high and the review base is small. The available data supports a stable medium-level commercial profile rather than a top-tier high-volume supplier profile.
Final Score: 16 / 20
4. Service Capability
Basis:
- Communication response time: ≤2h
- Full Customization: Listed
- ODM service available: Listed
Elaboration:
The supplier’s response time of within 2 hours indicates reasonably efficient communication, suitable for buyers requiring timely pre-sales or project discussions. The presence of Full Customization and ODM service labels suggests that the supplier can support customized requirements beyond standard catalog sales. This is relevant for axial fan impeller products, where buyers may need different dimensions, blade designs, or application-specific configurations; however, the provided data does not specify actual customization scope, engineering capacity, or sample development timelines.
Scoring Rationale:
The supplier has good service indicators, especially customization and ODM labels. However, the response time is ≤2h rather than ≤1h, so it does not meet the highest service-performance threshold. In addition, there is insufficient data on technical support team size, drawing capability, sample lead time, or after-sales response process.
Final Score: 8 / 10
5. Delivery Performance
Basis:
- On-time delivery rate: 83.3%
Elaboration:
An on-time delivery rate of 83.3% indicates that the supplier generally completes shipments within the expected timeframe, but there is still a visible risk of delay. For buyers with flexible procurement schedules, this level may be acceptable. For buyers operating strict production planning, maintenance schedules, or project-based installation timelines, the delivery performance should be monitored carefully.
Scoring Rationale:
According to the scoring standard, an on-time delivery rate between 80% and 89% corresponds to 7-8 points. Since the supplier’s rate is 83.3%, it falls in the lower-to-middle part of that range. The score reflects acceptable but not strong delivery reliability.
Final Score: 7 / 10
6. Quality & Customer Feedback
Basis:
- Store rating: 4.9
- Review count: 10
- Finished Product Inspection: Listed
- Verified supplier: True
- Warranty available: Listed
Elaboration:
The supplier’s 4.9 rating is a positive quality signal, and the Finished Product Inspection label indicates that some level of outgoing quality control is available. Warranty availability also supports buyer confidence. Verified supplier status further strengthens the quality credibility profile from a platform perspective. However, the review count of 10 is limited, so the rating is based on a relatively small customer feedback sample. There is also insufficient data on defect rates, inspection standards, test reports, quality management certifications, or product-specific compliance testing.
Scoring Rationale:
The supplier shows good quality-related indicators, including a high rating, Finished Product Inspection, warranty label, and verified supplier status. The score is not placed in the highest range because customer feedback volume is limited and no detailed quality certification or inspection documentation is provided. The quality profile is credible but not fully proven at scale.
Final Score: 16 / 20
Total Score
77 / 100
- Company Strength: 14 / 20
- Platform & Compliance Credibility: 16 / 20
- Business Performance: 16 / 20
- Service Capability: 8 / 10
- Delivery Performance: 7 / 10
- Quality & Customer Feedback: 16 / 20
Procurement Recommendation
Cooperation is recommended with controlled risk management. Qingdao Damuyuan Machinery Manufacturing Co., Ltd. appears suitable for buyers seeking aluminum axial fan impellers or axial flow fan products with low MOQ requirements, customization support, ODM service availability, and moderate transaction assurance through .
The supplier is best suited for small-to-medium procurement projects, customized component sourcing, trial orders, replacement part purchasing, or buyers who value Trade Assurance and platform-verified supplier status. It may be less suitable for buyers requiring fully proven large-scale production capacity, extensive customer review history, or very strict delivery reliability.
Main risks include limited employee scale data, only 10 available reviews, an 83.3% on-time delivery rate, and insufficient data on formal factory certifications, production capacity, testing standards, or international compliance documents. Growth potential exists due to its verified status, CN¥3M+ recent transaction value, customization labels, and focused product category, but buyers should request samples, inspection records, production lead-time confirmation, and quality documentation before placing large-volume orders.
