Improvement of design of cylinder liner centrifugal casting mold

Large cylinder diameter wet diesel engine cylinder liner (≥φ125), usually used for single casting. According to the traditional mold design process, the produced blank is heavier, the casting cost is higher, and the machining allowance is large. Therefore, it is imperative to reduce the weight of the cast blank and thus reduce the machining allowance. […]

Application Analysis of Aluminum Alloy Gravity Casting Mould

While advanced equipment is an indispensable factor in ensuring product quality, the role of molds in casting is also very important. Especially for aluminum alloy and aluminum alloy auto parts manufacturers, the accuracy and durability of aluminum alloy casting molds have an obvious impact on product quality. For ferrous metal casting, the mold is more […]

The advantages and disadvantages of metal casting and sand casting!

Sand casting, as the name suggests, uses the sand mold as the basic mold, and the metal solution is poured to form the desired casting. At present, iron, steel and many non-ferrous metals can be obtained by this method. Its advantages are: low material prices, easy access, adaptability, and a wide range of applications, whether […]

Importance of casting molds in sand casting

The factory refers to the casting mold as the “mother of casting”, which can be said to be a high-level summary of the role and status of casting molds in casting production. It is called “mother”. One of them is because in the factory, all the castings are made by molding the sand mold, and […]

Heat treatment technology and method for casting mold

With the continuous improvement of science and technology, the mold industry has gradually become an indispensable product in the manufacturing and manufacturing enterprises, resulting in a large increase in the number of molds. As the number of molds increases, people gradually become more and more demanding. Among them, the casting mold is a typical representative […]

Lost mold of motor casing

R&D background: As of 2017, China’s total installed capacity of electric motors has reached more than 400 million kW, and the annual power consumption has reached 1.2 trillion kWh, accounting for 60% of the country’s total electricity consumption, accounting for 80% of industrial electricity consumption, including fans, pumps and compressors. The total installed capacity has […]

Special requirements for molten iron in lost foam casting

The quality of molten iron has a great influence on the lost cast iron parts. The influence of improper misalignment temperature on the defects of lost cast iron parts and the requirements of hot metal quality of different cast iron parts are analyzed. The measures and adjustment methods to prevent casting defects are analyzed. Lost […]

How to obtain a uniform density of lost foam pre-expanded beads

The density of the lost foam pre-expanded beads determines the density and degree of fusion of the various parts of the die, and the quality of the die determines the quality of the casting. The main factors affecting the density of the pre-expanded beads of the lost foam are the quality of the raw materials […]

Automatic ejection for the application of lost foam technology

One of the characteristics of the mold-molding mold is that hot steam and cooling water need to be introduced into the closed mold gas chamber to mature and cool the foam particles, which is different from the molding environment of molds such as plastic molds, metal molds and die-casting molds. The mold needs to form […]

Application of lost foam coating on large mold castings

With the rapid development of the automobile industry, the production and use of large-scale stamping parts has increased sharply, and the demand for medium and large-sized molds has also increased significantly. In recent years, a large number of researches and practices have shown that the yield strength of nodular cast iron is higher than that […]
