Typical MOQ

Depends on part complexity and whether tooling already exists; with a new mold, per-part MOQ is often driven by amortizing the tooling cost rather than a fixed unit minimum.

Typical Lead Time

New mold/tooling: 4–8 weeks. Production once tooling exists: 2–4 weeks per run.

Plastic Injection Molding OEM — FAQ

Who owns the mold/tooling — the factory or me?

Standard practice is that the buyer who pays for the tooling owns it, and can request it be released to a different factory later. Get this in writing before paying for a mold — it's the single most common dispute in injection molding OEM.

Can a Thai molder handle my resin spec, or only their standard materials?

Most factories run a standard set of resins (PP, ABS, PC, nylon, etc.) they stock in volume for cost efficiency. A less common or medical/food-grade resin may require the factory to special-order material, which affects both price and lead time — confirm before quoting.

How many cavities does a typical mold have, and does that matter for my order size?

Cavity count directly drives cycle output — a single-cavity mold is cheaper to build but slower per part; multi-cavity tooling costs more upfront but lowers per-unit cost at volume. Ask the factory to quote both options if your order size isn't fixed yet.
