Low Pressure Die Casting
Molten aluminium fills the mould upward under low pressure, delivering dense structure with minimal porosity for thin-wall, pressure-tight parts.
Low pressure casting, gravity casting, CNC machining and X-ray inspection all under one roof — from tooling to finished parts.
Two casting processes plus an in-house machine shop
Molten aluminium fills the mould upward under low pressure, delivering dense structure with minimal porosity for thin-wall, pressure-tight parts.
Tilt-pouring into permanent moulds — ideal for medium to large thick-wall castings with lower tooling cost and faster sampling.
In-house machining centres deliver casting + machining from one source, with full control over dimensional and geometric tolerances.
Founded in 2018, Zhejiang Mingdao Thermal Technology Co., Ltd. is a technology-oriented SME in Quzhou, Zhejiang, covering tooling, aluminium casting and precision machining on a 4.1-hectare site.
We develop and manufacture condensing gas boilers, boiler parts and aluminium castings. Our 7,500 m² foundry workshop (18 m clear height) operates under an approved casting capacity of 20,000 t, covering aluminium casting, sand reclamation, pickling and powder coating, with environmental, safety and energy assessments all approved.
