Effective Auxiliary Materials for VProcess Casting with fused ceramic beads and electrofused alumina sand ideal for vacuum sealed molding

In the V-process (Vacuum Sealed Molding) casting, fused ceramic beads (electrofused alumina sand) are an ideal and widely used dry powder molding material.

Advantages:

1.Excellent Flowability (Core Advantage)

Principle: The fused ceramic beads are spherical and have smooth surfaces.

Effect: During sand filling in V-process molding, the spherical sand flows like water, easily filling deep cavities, internal corners, and complex geometries of the mold. It naturally compacts without bridging, greatly reducing manual compaction effort.

2.Low Thermal Expansion to Prevent Defects

Principle: The thermal expansion coefficient of fused ceramic beads is extremely low (approximately 1/10 of quartz sand).

Effect: During molten metal pouring, the sand mold undergoes minimal volumetric change, effectively preventing casting defects such as sand expansion or deformation. This makes it especially suitable for high-precision castings.

3.Good Permeability

Principle: The uniform void distribution between spherical particles ensures consistent airflow.

Effect: Combined with vacuum pumping, it efficiently evacuates gases from the mold cavity and vaporized gases from the plastic foam pattern, reducing defects such as porosity and pinholes.

4.Environmental and Occupational Safety Benefits

Principle: V-process sand handling generates large amounts of dust. Fused ceramic beads are synthetic, contain no free silica (silica dust), and generate less dust than quartz sand.

Effect: Significantly improves workplace conditions and protects worker health.

Zibo Tongpu Vacuum Equipment Co., Ltd. is located in the industrial machinery manufacturing base of China, the hometown of QlLU culture----.Gaoqing economic development zone, Zibo city of Shandong province.

Zibo Tongpu is a professional manufacturer that specialized in lost form and V-method casting equipment and all kinds of vacuum pumps. Here brought together a large number of science and technology workers at lost form and V-method casting for many years that have the rich experience. They are not only proficient in lost form and V-method design and manufacture of theoretical knowledge, but also have rich practical experience. So the equipment's new design could be more close to the users, more in line with the actual needs.

Zibo Tongpu founded in 2005, for the user to manufacture a number of lost form and V-method production lines successively. Including fully-automatic and semi-automatic production lines, but also tailored to the user's simple production line. Our products have a broad market, covering more than twenty provinces, cities and autonomous regions across in China. At the same time, exported to Thailand, South Korea, Taiwan, Vietnam, Indonesia, and Kazakhstan, Russia and so on countries and regions.

Zibo Tongpu has strong technical development and technology service capabilities. We can provide not only reliable casting equipment, but also lost form and V-method molding technology service. Meanwhile, we also undertake "turn-key" projects, according to customers’ demand. Besides, we have set up a foundry plant which adopts the lost form and V-method molding technique as main means of production so as to provide test base for customers to carry out first-phase product testing and stuff training. We provide a variety of services to need of customers at different levels.

We can willing to provide you our best and most sincere service! Let us join hands and work together for common development and growing. and achieve even greater glory. 

Zibo Tongpu can offer the following services:
