1. Start with a complete RFQ package
Send 3D files, 2D critical dimensions, material, texture, color, annual volume, cavity target, packaging needs and delivery milestone together. A complete package lets the supplier raise key questions before the tooling schedule is committed.
2. Set a fixed DFM and mold design approval window
Define who approves parting line, gate, sliders, lifters, cooling and ejection. Use one controlled revision for the design review and record open questions. Late changes after steel work starts are a common cause of rework and schedule loss.
3. Plan T1 around measurable acceptance criteria
Before the trial, agree on sample quantity, material, machine conditions, critical dimensions, appearance standard and assembly checks. After T1, classify issues as part design, mold correction or process adjustment so the next action is clear.
4. Protect the handover to production
Approval should include stable samples, inspection records, process notes, mold maintenance information and any spare insert list. For low-volume launches, a pilot run can expose packaging, assembly and batch variation before mass production.
5. Review your schedule with Huanze
Huanze supports overseas buyers with RFQ review, DFM, mold design, T1/T2 trial, inspection and production handover for plastic housings and precision molded parts. Contact Annie by WhatsApp, WeChat or phone at +86 15801883001, or email annie@huanzekeji.com.
