Professional AODD Pump Mold Manufacturing | Full Size & Full Material Experience

Air-Operated Double Diaphragm (AODD) pumps are widely used in chemical, sewage, coating, food and mining industries due to their explosion-proof performance, strong corrosion resistance and flexible conveying capacity. Different from ordinary plastic products, pneumatic diaphragm pump parts feature complex structures, strict assembly tolerance, high anti-leakage requirements and diverse material adaptation, which bring high technical challenges for mold development.

As an experienced custom injection mold manufacturer, Hongmei Mould has extremely rich experience in diaphragm pump mold development. We have completed mold manufacturing for full sizes and full series of pneumatic diaphragm pumps, covering aluminum alloy pump casing, stainless steel pump structure, PP anticorrosive pump, PVDF strong acid-resistant pump and various rubber & PTFE diaphragm accessories. Whether it is small industrial pumps or large-flow engineering pump molds, we have mature and mass-proven solutions.

We fully understand the structural principles and industrial application requirements of AODD pumps. During mold design, we precisely control the sealing surface tolerance, diaphragm assembly position, valve ball flow channel and air passage structure. Our optimized mold structure effectively solves common problems such as liquid leakage, poor suction, unstable flow and assembly failure during pump operation, ensuring high matching accuracy and long service life of finished pump parts.

We provide reliable one-stop mold customization services, covering product structure optimization, professional mold design, high-precision CNC machining, full-process mold trial and mass production verification. All diaphragm pump molds adopt standard high-quality mold bases and optional high-grade steels including 718H and S136. Strict pre-delivery testing ensures stable size accuracy, good wear resistance and excellent sealing performance for long-term industrial use.

With standardized quality control standards throughout production, our delivery cycle is stable at 25–35 working days. With abundant full-size and full-material diaphragm pump mold project experience, Hongmei Mould has become a reliable partner for global industrial pump manufacturers, supporting customized development of various new pneumatic diaphragm pump products.
