BEFORE WE START
Good questions.
Clear next steps.
Everything starts with understanding the wire your process needs.
Talk to JinweiWhat information is needed for a quotation?
Send conductor diameter, wire type, insulation build or finished outside diameter, thermal class, application, spool requirements, trial quantity and delivery destination. Attach an existing datasheet or drawing if you have one.
Can I discuss a trial sample first?
Yes. We review the specification before discussing a trial. Sample quantity, availability, charges, freight and evaluation requirements are agreed for each enquiry.
How are price and lead time confirmed?
Price, minimum order quantity, production lead time, packaging, payment terms and delivery terms are agreed in the quotation after we review your requirements.
Can you help identify an equivalent wire?
Send your current wire designation and datasheet. Similar model names do not always mean identical performance, so the proposed specification is reviewed before sampling.
