1. Start with one controlled RFQ package
When files arrive in many emails, mistakes become more likely. A controlled RFQ package should include latest drawings, material, surface finish, expected volume, target market, critical dimensions and packaging requirements.
2. DFM feedback should be written and traceable
DFM comments about wall thickness, draft, ribs, parting line, gates, slides, tolerance and assembly risk should be recorded before mold design approval. Written decisions reduce misunderstandings across time zones.
3. T1 samples need more than photos
Photos are useful, but buyers also need sample quantity, material batch, process condition, dimensional inspection, appearance notes and a correction list. This information helps decide whether T2, texture, painting or pilot production can proceed.
4. Separate design changes from mold corrections
Design changes after steel cutting affect time and cost differently from mold corrections. A good supplier explains the impact before work begins, so buyers can approve changes with clear expectations.
5. Keep production records for repeat orders
For repeat molded plastic parts, process records, inspection results and approved samples help the next batch stay consistent. This is important for plastic housings, connector parts, automotive components and medical device enclosures.
6. Communicate with Huanze directly
