BEFORE YOU SEND AN RFQ
Practical questions,
straight answers.
What information gives the most accurate quote?
A dimensioned drawing, material and finish requirements, quantity per order, estimated annual demand, inspection needs and packaging requirements.
Can you work from a physical sample?
Yes. We can begin with photos and measurements, then confirm whether reverse engineering or a physical sample is required.
Do you accept lower-volume custom projects?
It depends on the manufacturing process and tooling. Share the target volume and we will identify a realistic route or explain the constraint clearly.
Who is responsible for export and delivery?
Coland coordinates the commercial order, export documentation, agreed inspection and shipment terms with the customer.
