Price Comparison Among Top Suppliers: Balancing Cost and Value

While price is a significant factor, it should be analyzed in context with quality, lead time, and total cost of ownership. Consider the following comparative scenario for aluminum die-cast enclosures (1,000 pcs, 200g each):

Supplier	Unit Price (USD)	Lead Time	Mold Cost	Notes
Ningbo Surely Metal Technology Co., Ltd.	$1.45	25 days	$800 (refundable after 5K units)	Includes surface polishing and anodizing options
Qingdao Baoshengxin International Trade Co., Ltd.	$1.30	30 days	$1,200 (non-refundable)	Lowest unit price but longer lead time; ideal for budget-sensitive bulk orders
Huizhou Jiyan Hardware Co., Ltd.	$1.60	20 days	$900 (credited against first three orders)	Premium pricing justified by fast turnaround and free sample program
