What is the recommended working current?

16-22mA is appropriate; excessive current will affect laser power and tube lifetime.

How should the laser tube be installed?

Support points should be at 1/4 of the tube length, with water cooling flowing in from top and out from bottom.

What is the minimum order quantity?

The minimum order quantity is 1 piece.

AI-Powered supplier vetting

SummaryThe supplier is a limited company and is described elsewhere as a trading company with a combined business type. Its stated scope covers laser machinery and parts, mechanical equipment and components, and related manufacturing and sales activities. Evidence shows product development during the past year, ODM services, OEM service for recognized brands, and broad customization options. Service procedures, corrective/preventive action procedures, complaint-handling procedures, and finished-product inspection instructions are documented and followed. However, no SDK, overseas warehouse, overseas showroom, overseas agents or branches, or offline trade-show participation is reported. Financial records are identified for 2022–2024, but their content is not provided. No certifications or specific customer cases are stated.

After-Sales capabilityThe supplier has written and followed procedures for service capability assessment, corrective and preventive actions, and customer complaints. However, it reports no overseas warehouse, showroom, overseas agents or branches, or offline trade-show participation, so the evidence supports formal service processes but not broad overseas service coverage.

R&D capabilityThe supplier reports new products during the past year and provides ODM services, indicating active product-development capability. It does not have an available SDK, which limits evidence of software or development-platform support.

Production capacityThe stated business scope includes mechanical-equipment and mechanical-parts processing, while the product range includes laser machines, laser tubes, engraving and cutting machines, and marking machines. Finished-product inspections are conducted using instructions that are uniformly followed, although employee count is 19 and no detailed production capacity is provided.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, and minor customization. These options are stated consistently across the R&D and design-service information, providing direct evidence of broad customization coverage.

Client casesThe supplier states that it provides OEM services for recognized brands, which is evidence of brand-related customer experience. No customer names, project details, order examples, or verifiable case studies are provided, so the depth of its customer-case record cannot be determined.
