Ruian Yumin Machine Screw Co., Ltd.

Ruian Yumin Machine Screw Co., Ltd. offers a full range of industrial machinery including screw pumps, filters, gear boxes, and plastic recycling equipment — ideal for buyers in manufacturing or waste processing sectors. Being based in China since 1988 gives the company long-term experience and stability in supplying reliable mechanical solutions. The lack of verified work email, phone, and documents raises concerns about identity and communication reliability — buyers should request additional proof before placing large orders. Without verified contact details, it's harder to confirm responsiveness or track inquiries, which increases risk in negotiations. While the company has a long operating history, the missing verification signals a need for due diligence before trusting the business with sensitive or large-volume purchases.
