We stock and process 50+ engineering resin grades. Common materials always in stock include: PP, ABS, PA6, PA66, PA66+GF30, PC, POM, TPU, TPE, PBT, PC/ABS, and more.

Specialty grades such as PEEK, LCP, PEI, and reinforced compounds are available via 3–5 day regional procurement. If you have a specific material spec, just mention it in your inquiry and we’ll confirm availability immediately.

If parts arrive defective, out-of-spec, or incorrect — and the issue is attributable to our production — we take full responsibility. Our standard resolution is replacement production at no cost, prioritized in our schedule.

To process a claim, please send us: photos of the issue, affected part quantity, and the specific defect description. We’ll respond within 24 business hours with a corrective action plan. We ask that you report quality issues within 30 days of receipt for us to initiate a claim.

We primarily ship on FOB Xiamen terms — major international ports are within close proximity to our Zhangzhou facility. You handle freight from there using your preferred forwarder.

We also accommodate CIF (Cost, Insurance, Freight) and DDP (Delivered Duty Paid) for buyers who prefer a door-to-door arrangement. If you have a preferred freight partner, we can work with them directly.

Simply submit an RFQ with your part drawing (or description), estimated quantity, and material preference. A real engineer reviews every inquiry — we don’t use auto-response pricing calculators.

For standard parts, we typically respond within 4–8 business hours. For complex custom parts requiring a full DFM review, expect a response within 24 business hours. The quote will include itemized mold cost, unit price, lead time, and material spec — no bundled or hidden figures.

Yes — T1 trial samples are a standard part of every new mold project. After the mold is built, we run first-shot samples and send them to you physically for dimensional, functional, and visual evaluation. We don’t proceed to mass production until you approve.

For existing catalog-style products (parts we already produce), we offer physical samples for qualified buyers — you cover shipping costs only. Contact us to request samples of specific parts.

Every production batch goes through a three-stage QC process:

1. First-Article Inspection — the first shots of every run are measured against drawing dimensions before full production begins.

2. In-Process Checks — operators perform dimensional spot-checks and visual inspection at regular intervals throughout the run.

3. Final Inspection — 100% visual inspection of all finished parts before packing, with AQL-based dimensional sampling for critical features.

Batch traceability records are maintained so any issue can be traced back to specific production parameters.
