FAQ
Tooling-development projects are priced by the mold, with no hard MOQ; injection-molding mass production typically recommends batches of ≥5,000 pieces to amortize mold-change and setup costs. For small-batch prototyping, 3D printing or a simple mold may be used—please contact engineering for evaluation.
Conventional precision molds take about 25–40 days from DFM review to T0 trial, and complex two-color / export molds about 45–60 days. Milestone feedback is provided to ensure transparent and controllable progress.
Yes. All new projects undergo DFM review with a report, key parts receive a mold-flow analysis report, and we predict filling, warpage, and weld-line risks in advance to reduce mold-trial counts.
We support silk-screen printing, pad printing, laser engraving, spray painting, electroplating, vacuum coating (PVD), ultrasonic welding, and finished-product assembly, enabling one-stop delivery from parts to finished goods.
The company is certified to the ISO9001:2015 system, equipped with 2.5D, CMM, and other inspection equipment, and implements a full-inspection flow of incoming IQC, in-process IPQC, and outgoing OQC; measurement reports are issued for critical dimensions, with first-pass yield maintained above 99.5%.
