Air Valves & Date Stamps

Air valves and date stamps are precision mould components used to support reliable part release, mould venting and product traceability in injection moulding applications. Correct selection and accurate installation help improve mould performance while providing clear identification of manufacturing dates, batch information or production cycles where required.

Gumao Precision supplies air-control and identification components designed for dependable operation in high-cycle mould environments. Accurate machining and consistent dimensions help ensure components integrate correctly with the surrounding mould structure and continue to operate reliably during repeated production cycles.

Reliable Mould Operation and Traceability

Air valves can assist with controlled air release and part ejection, helping reduce sticking and support smoother demoulding. Date stamps provide a practical way to identify production information directly on moulded components, supporting quality management and manufacturing traceability.

Gumao Precision manufactures precision mould components for injection mould applications from its manufacturing base in Dongguan, China. Standard and custom component requirements can be discussed according to the mould design, dimensions and intended application.
