Plastic Injection Molding OEM in Thailand
Plastic injection molding is one of Thailand's deepest manufacturing capabilities, serving automotive, electronics, packaging, and consumer-goods OEM production. These are injection molding and mold-making factories — cross-checked against Thailand's DBD company registry and Google review history.
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.
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.
