How are twist locks packaged for export?

Standard bundles (10 or 20 pcs) on wooden pallets, or bulk packed in heavy-duty steel wire mesh containers or wooden crates, all clearly marked.

What is the difference between a 'Fixed Head' and a 'Flux Head' Twist Lock?

Fixed Head is permanently attached for harbor/yard use. Flux Head is removable for cellular ships to prevent damage to cell guides during extreme lifting angles.

How do I choose between Manual, Semi-Auto, and Auto Twist Locks?

Manual is economical for yards; Semi-Auto reduces fatigue for frequent handling; Automatic is essential for high-speed terminals and container ships without manual intervention.

Can you provide custom marking or branding?

Yes, we offer full OEM services including forging company logos, custom packaging, labeling, and product modifications for specific requirements.

What is your MOQ (Minimum Order Quantity)?

Standard locks require 500 pieces, Flux Head/Special types require 200 pieces, and OEM/Large Project orders are negotiable based on container load quantities.

What is your production lead time?

Samples take 15-20 working days, standard orders 30-45 working days, and custom/OEM orders with certification 60-75 working days.

AI-Powered supplier vetting

SummaryWeifang Shengao Machinery Co., Ltd. is a limited company focused on mechanical parts, hardware, metal tools, CNC machine tools, and related components. It identifies as a professional technical supplier and offers 3D software design and broad customization services, including sample-, design-, full-, minor-, and flexible customization. The supplier has written procedures and records for service assessment, corrective actions, and complaint handling. Its export sales share is stated at 71%–90%, with three years of export experience. However, the supplier has nine employees, only two years of total R&D engineer experience, no new products in the past year, no ODM, SDK, or overseas service infrastructure, and no stated customer cases. Audit information is provided for a TUV Rheinland audit with a validity period from September 4, 2025 to September 3, 2026, but the evaluation result is recorded as 0 and no certification name is specified.

Supplier typeThe supplier explicitly identifies as a professional technical supplier and a limited company. Its stated business and product scope covers mechanical parts, hardware products, metal tools, CNC machine tools, functional components, forgings, and powder metallurgy products; the audit record identifies mechanical parts as the primary product.

After-Sales capabilityThe supplier has clear written procedures and followed records for corrective and preventive actions and for handling customer complaints. This directly supports an established service-response process, although the slices do not provide service performance results or response-time data.

Production capacityThe supplier reports an annual production output range, six to ten quality-control staff, on-time delivery, random production quality inspection, and its own factory. It has nine total employees, so the available evidence supports an operating production capability, while capacity beyond the stated output range cannot be determined.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization, and also welcomes OEM and ODM requests according to its company description. These repeated statements provide direct evidence of broad customization coverage, although the separate record states that ODM is not available, creating a conflict on ODM specifically.
