Precision casting

Our factory possesses end-to-end precision casting production capabilities, with the complete process comprising the following stages in sequence: wax pattern fabrication, shell mould fabrication, dewaxing, shell mould baking, metal smelting, casting, heat treatment and shot blasting finishing. All processes are carried out in-house, enabling integrated production and delivery from rough castings to finished products.

The materials we routinely produce include mainstream industrial metals such as stainless steel, carbon steel, low-alloy steel, medium-alloy steel, high-manganese steel and nickel-based alloys; all materials are manufactured in strict compliance with the relevant industry standards. For special custom material requirements, we can adapt our processes and carry out production in accordance with the material specifications provided by the customer.

The product’s weight range is from 0.1 kg to 100 kg, covering everything from small, precision components to medium-sized industrial castings. Dimensional accuracy strictly complies with leading international tolerance standards such as VDG-Merkblatt P-690-D2, DIN 1680, JIS B 0403 and ISO 8062, ensuring high-precision moulding for products of all specifications.

Our factory strictly adheres to four major international standards for dimensional tolerances: German VDG-Merkblatt P-690-D2, DIN 1680, Japanese JIS B 0403 and International ISO 8062. The production and inspection of all products are benchmarked against the corresponding standards. Through process optimisation and precise control, we can consistently ensure that product tolerances comply with specifications and that dimensional errors remain within controlled limits, thereby meeting the requirements of precision assembly. Detailed tolerance parameters can be found in the Product Quality Standards Manual.

Magma is a state-of-the-art casting simulation system, primarily used for preliminary process design. It enables the simulation of the entire process—from metal melting and pouring to solidification—in advance, allowing for the accurate prediction of potential defects such as porosity, shrinkage cavities, deformation and segregation that may occur during the casting process. This facilitates the early optimisation of parameters such as pouring temperature, pouring speed and mould parameters, thereby eliminating production defects at source, improving product yield and process stability, and is particularly well-suited to the process development of complex castings.

Yes. Utilising a ceramic sand core moulding process combined with proprietary specialised casting techniques, and optimised through Magma simulation, the equipment overcomes the limitations of traditional casting structures and is capable of consistently producing a wide range of castings featuring irregular shapes, complex internal cavities, irregular curved surfaces, openwork structures and other highly challenging castings, meeting the development and mass production requirements for all types of non-standard, complex and precision components.

Yes. The complete production process includes heat treatment and shot blasting. Heat treatment effectively optimises the internal microstructure of castings, enhancing mechanical properties such as hardness, toughness and wear resistance, whilst eliminating internal casting stresses; Shot blasting removes scale and burrs from the surface of the castings, optimises surface roughness, and improves the product’s visual quality and corrosion resistance, ensuring that the finished products meet both performance and aesthetic standards.

Comprehensive support. For new products with complex structures, we can utilise Magma simulation processes and ceramic sand core technology to carry out rapid process development and prototype production; at the same time, we cater to both small-batch customisation and medium-to-large-scale mass production requirements, with standardised production throughout the entire process. This ensures both the precision of new product development and the stable delivery of bulk orders, striking a balance between flexibility and efficiency.
