Introduction of three process methods for lost foam casting

The development and continuous improvement of the lost foam casting method is the evolution process from the foam model wet sand method (FM method) to the foam model thousand sand negative pressure method (FV method). This kind of evolution is not only the evolution of the modeling method, but the fundamental change of the process […]

Lost foam casting process and precautions

Lost foam casting is mostly made of foam as a mold, and is also called “dry sand solid casting” and “negative compact casting” in China. In the casting process, it includes the design of the riser system, the pouring temperature control, the pouring operation control, the negative pressure control and other links, which need to […]

What are the differences between lost foam casting and sand casting?

With the continuous development of the foundry industry, the most popular casting process used by Chinese foundry manufacturers in 2017 is lost foam and sand casting. Generally, manufacturers of single large-volume precision castings generally adopt the lost foam casting method, which mainly undertakes outsourcing and zero-lived foundry manufacturers. Most lost foam and sand casting are […]

Sand casting method, full solution of technical parameters

The sand molding process plays an important role in the casting production process, which directly affects the quality level, production cost, production efficiency and environmental pollution degree of the casting. The sand casting method can be divided into two categories: physical hardening modeling method and chemical modeling method. The physical hardening modeling methods mainly include […]

Casting mold parts take advantage of the forging process

Blanks of lost foam casting mold parts are generally formed by forging, and the purpose of forging is to obtain a certain geometric shape, so as to save raw materials, save processing time and reduce cost. First. Forging temperature The initial recrystallization temperature of steel is about 727 ° C, but 800 ° C is […]

Lost foam casting process

Lost foam casting, also called solid casting, is a model of a foam model with the same shape and shape as the casting. After brushing the refractory paint and drying it, it is buried in the dry sand and is molded under vacuum and under vacuum. The gasification of the model, the liquid metal occupying […]

Defects and preventive measures in the heat treatment of lost foam molds!

Although the application of lost foam casting technology in China has been slow, it has developed rapidly in recent years. In particular, due to the low investment in lost foam casting equipment and short process routes, many original small and medium-sized foundry companies are increasingly adopting this technology. However, some companies have failed to pay […]

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 […]
