AoTo Precision Mold Co., Ltd. is based in Dongguan, Guangdong, and focuses on injection molds for high-performance resin and engineering plastics — mold development, molding and small-batch rapid tooling for PEEK, PEI, PPS, PPSU and related specialty grades.
We keep material specialists and experienced injection engineers on the team, and we deliver a one-stop steel-to-plastic solution from material analysis and material testing through to small-batch production.
We do not spread across general-purpose molding. Capacity, drying, temperature control and our process database are all built around high-temperature engineering plastics. That focus is the whole proposition.
Capacity and process system are built around high-temperature engineering plastics — oil temperature control, desiccant drying, a dedicated process database.
Every project starts with grade selection. Brand grades (Victrex / Solvay / Evonik) and domestic alternatives are evaluated in parallel, with a CoA supplied with the goods.
Moldflow before steel, full-dimensional first-article FAI, key dimensions under SPC at CPK ≥ 1.33.
DFM feedback in 48 hours, rapid tooling samples in 7–15 days, and proactive updates at every milestone.

Specialty-plastic molding is an industry built out of details. Half an hour short on drying, 5 °C off on mold temperature, 0.005 mm short on venting — and the result is a different part. "Ao Tu" is the Chinese for concave and convex: two surfaces that only work when they match exactly.
We hold the detail and take on the difficult part. That is the whole idea behind the name.
