The special repair paste for lost foam casting is a paste-like material used in the lost foam casting process to repair defects in foam patterns (such as EPS and STMMA materials), including joints, pits, edge losses, and coarse bead structures. It helps improve casting surface accuracy and smoothness, thereby ensuring overall casting quality.

Features:

1.Strong Bonding Performance

The repair paste provides excellent adhesion to foam patterns and does not easily peel off after application, making it suitable for filling, leveling, and smoothing various pattern defects.

2.Easy Vaporization with No Residue

During pouring, the repair paste vaporizes rapidly and leaves no residue on the casting surface, effectively preventing inclusions and related defects.

3.Low Gas Generation

With low gas evolution during vaporization, the paste helps reduce the risk of gas porosity and improves the overall acceptance rate of castings.

4.Convenient Application

The paste can be applied manually or with simple tools. It cures quickly and does not interfere with subsequent coating application, making it suitable for fast on-site repairs.

5.Environmentally Friendly and Safe

Most formulations are water-based, with low odor, non-toxic properties, and no corrosive effect on foam patterns, ensuring safe and environmentally responsible operation.

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.
