Casting Mold Seam Width 0.5mm Copper Exhaust Plug Ventilation Particle Foam Mold Gas Cork Lost Foam Copper Gas Cork

Our company specializes in the production of vent plugs (vent capsules), which are developed for casting mold venting and foam molds. they are easy to replace and have excellent performance. this exhaust plug has a variety of series such as honeycomb-shaped, groove-shaped, porous-shaped, and mesh-shaped. it has been widely used in gravity casting, vacuum casting, injection molding and other processes. the outer diameter is a standard size, with a total of 30 types from φ4--φ25. materials are divided into: brass, aluminum; etc. cheap and widely used.

 

An exhaust plug is a mold component used to vent air and other contaminants from within the mold cavity, thereby improving the quality of the molded product. also known as: honeycomb vent plug, breather plug, vent plug, or cylindrical vent plug.

Usage: used for aluminum alloy, copper, tin and other non-ferrous metals and alloys for low-pressure casting mold exhaust, such as injection molding molds, gravity casting molds, vacuum casting molds, and low-pressure casting molds. the casting exhaust plug has two functions: 1. make the sand core solid; 2. for the cold core box, it is to ensure that the blowing gas penetrates the entire sand core without producing dead ends.

In a broad sense, casting includes die casting, but what we usually say is die casting is high-pressure casting through a die casting machine. narrowly speaking, casting refers to sand core casting.

We offer exhaust plugs for casting molds, available in materials such as aluminum and copper.
