Sourcing Plastic Injection Moulding in Vietnam
What an industrial buyer needs to know before requesting quotations for plastic injection moulding from Vietnam-based suppliers.
Overview
Sourcing plastic injection moulding from Vietnam is one of the recurring decisions of any industrial buyer who needs to balance unit cost, quality control and lead time. This page collects what an EU buyer should know before opening a Request for Quotation for plastic injection moulding suppliers in Vietnam: typical materials, tolerances expected on the drawing, certifications worth asking for, current price positioning and shipping turnaround.
From a pure cost angle, Vietnam prices plastic injection moulding roughly 40–60% lower compared to the average European baseline. Real numbers depend on volume, alloy and surface treatment, but this gap is what justifies a sourcing exercise toward Vietnam in the first place. Cost is rarely the only variable: lead time, audit access, certifications and supplier capacity at the right volume usually decide which suppliers actually make the shortlist.
A typical first article from a Vietnam-based plastic injection moulding shop takes 30–90 working days, plus 28–42 shipping days of shipping to central Europe. Series production lead time depends on volume and capacity reservation: most established shops want a forecast horizon of 60 to 90 days to plan raw materials and surface treatment subcontractors.
When to choose this process
Pick injection when volumes are >5k pcs/year and geometry tolerates 0.5–2° draft and shrinkage compensation.
Injection moulding melts polymer pellets and injects them into a steel/aluminium mould. Tooling is expensive (€8k–€80k+) but unit cost drops dramatically above 5–10k pcs/year.
Why source here — Vietnam
- EU-Vietnam FTA (EVFTA): most tariffs eliminated by 2027
- Hourly cost 30–40% below China
- Lower IP risk than China, English-friendly export staff
- Korean and Japanese investors raised QA bar across clusters
What to watch out for
- Sea freight 28–42 days, sensitive to typhoon season
- Limited capacity on very large castings and forgings
- Power outages possible in Q2/Q3 — check supplier backup
Typical materials
- ABS
- PP
- PA6/PA66 (+GF)
- POM
- PC
- PEEK (high-end)
Typical tolerances
±0.05–0.2 mm depending on size; mind shrinkage and warpage.
Certifications to ask for

Frequently asked questions
Is it worth sourcing plastic injection moulding from Vietnam?
It pays off when the lower hourly rate (40–60% lower) beats the logistic friction (28–42 shipping days) and the selected supplier holds the required certifications (ISO 9001, IATF 16949 (top tier)). Below ~200 pcs/year it often doesn't; above ~1,000 pcs/year the math almost always tips in favour.
How much does an injection mould cost?
Single cavity prototype mould €8–15k, 2–4 cavity production mould €25–60k, hot-runner 8+ cavities €70k and up. Steel grade and life cycle drive cost.
Vietnam or China?
Vietnam if you want China+1 risk diversification, smaller volumes with friendlier IP, or to benefit from EVFTA duties. China if you need full vertical integration or massive volumes.
