Vacuum Docking Machine

The pneumatic vacuum docking machine is a critical connection device between sand boxes and the vacuum system in a lost foam casting production line. It uses pneumatic drive technology to achieve fast, automatic, and sealed docking and separation between the sand box vacuum chamber and the fixed vacuum pipeline, establishing a stable vacuum environment. The reliability and stability of this device directly impact production line efficiency and final casting quality.

Core Functions

1. Automatic Docking and Separation:
Under production line takt control, the machine automatically connects the vacuum pipeline when the sand box reaches the designated position and disconnects after pouring is completed.

2. Ensured Sealing:
Provides high sealing performance at the vacuum interface during docking, maintaining the required vacuum level inside the sand box and preventing air leaks that could cause casting defects.

3. Adaptation to Production Line Rhythm:
Fully pneumatic or combined pneumatic–electrical control ensures fast response, meeting the continuous operation requirements of automated production lines.

This device is essential for maintaining a stable vacuum environment, ensuring consistent casting quality, and supporting smooth, automated lost foam casting operations.

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.
