Can you manufacture from drawings or samples?
Yes. The supplied product documents describe custom manufacturing based on drawings or samples. Share the drawing revision, dimensions, material, finish and quantity for project review.
Which materials can be considered?
Depending on the component, our product documents list aluminum alloys, stainless steels, brass and engineering plastics. Please specify the exact grade in your inquiry; material suitability is confirmed for the project.
What surface finishes are available?
Available options depend on the part and material. Examples in our product documents include anodizing, passivation, plating, sandblasting and polishing. Specify your finish requirement for technical confirmation.
What information is needed for a quotation?
Send drawings or samples, the material grade, quantity, finish, critical dimensions and inspection requirements. Include your company name and a contact email so our team can clarify requirements and respond.
What is the lead time?
Lead time depends on geometry, material, quantity, finishing and inspection needs. Different source documents describe different indicative schedules, so the website does not promise a single lead time. Your quotation will confirm the applicable schedule.
Can I review quality documentation?
The supplied company materials include an ISO 9001:2015 quality management system certificate. Contact us to discuss the certificate and the inspection or material documentation needed for your project.
