Sourcing Plastic Injection Moulding in Mexico
What an industrial buyer needs to know before requesting quotations for plastic injection moulding from Mexico-based suppliers.
Overview
Sourcing plastic injection moulding from Mexico 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 Mexico: typical materials, tolerances expected on the drawing, certifications worth asking for, current price positioning and shipping turnaround.
From a pure cost angle, Mexico prices plastic injection moulding roughly 20–35% 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 Mexico 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 Mexico-based plastic injection moulding shop takes 30–90 working days, plus 18–30 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.

Frequently asked questions
Is it worth sourcing plastic injection moulding from Mexico?
It pays off when the lower hourly rate (20–35% lower) beats the logistic friction (18–30 shipping days) and the selected supplier holds the required certifications (ISO 9001, IATF 16949). 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.
Is Mexico useful for an EU buyer?
Yes if your end-customer is in North America: ship directly from Mexico to your US/Canadian warehouse under USMCA, skipping EU re-export friction.
