BEFORE YOU SEND YOUR DRAWINGSA clearer start.
A clearer start.
Fewer unknowns.
Not sure which route to choose? Tell us what the part needs to do and which requirements matter most.
Talk with CKDo I need to choose a process before contacting CK?
No. Send the drawing, quantity and intended use. Our team can review manufacturability, material and finishing requirements with you before recommending a route.
Can I order a single part or a small batch?
Yes. Custom one-off parts, prototypes and low-volume production are part of CK’s service. Availability, cost and lead time are reviewed for the individual project.
Can metal printing and CNC machining be planned together?
Yes. Mark the critical interfaces, tolerances and surfaces on the drawing so machining allowance, tool access and workholding can be reviewed before printing.
Can one enquiry include several parts and different processes?
Yes. You can upload a drawing pack, ZIP file and Excel parts list together. Identify each part and include its quantity, material and finishing requirements in the files.
What files should I send for an engineering review?
Send the 3D model and a dimensioned drawing for critical features, together with quantities and relevant specifications. STEP is useful for machining review; printing files and the preferred format can be discussed with the team.
How are quality and delivery requirements confirmed?
The quotation and project review define the agreed material, finish, inspection scope and lead time. Include any required reports, material documents or delivery constraints with your enquiry.
