A: Priority should be given to: rated power, maximum speed, disc size, motor type (brushed/brushless), body weight, application (cutting/grinding/polishing), and overload capacity for specific working conditions.
Q: What price discounts can be obtained for bulk procurement?
A: Typically, orders of 50+ units receive a 5%-10% discount, 100+ units receive 10%-15%, and 500+ units allow for further negotiation. Exact discounts are determined through negotiation based on product model and quantity.
Q: What are the main stages in the customization process for handheld angle grinders?
A: The main stages are: Requirement communication → Model selection → Design of customized solution → Sample production and confirmation → Mass production → Quality inspection → Packaging and delivery. Intensive communication is required to ensure requirements are met.
Q: Which logistics methods are typically used for international shipping?
A: Based on volume and urgency: Sea freight (large batches, 15-45 days, low cost), Air freight (small batches, 3-7 days, higher cost), and Express (samples, 5-10 days). Customers can choose the most suitable method.
Q: What quality inspection stages are performed before the product leaves the factory?
A: The process includes: Incoming inspection (parts) → In-process inspection (assembly) → Finished product inspection (power, speed, insulation resistance, no-load test) → Third-party inspection (per client request) → Packaging inspection.
