Ven-Cast™ is designed as a premium foundry sand additive to improve sand flowability and to enhance physical characteristics of green sand molds.
Ven-Cast™ is a micronized, surfacemodified organic fiber derivative. It is composed of solid, elongated, fibrous particles which range in size from a few microns to 1 mm in length. Ven-Cast™ is prepared by chemical and mechanical degradation of selected organic fibers. The extremely fine fibers are chemically modified to produce a novel class of derivatives, having unique properties from most commercially available products.
The primary application of Ven-Cast™ is in sand systems used for casting aluminum, magnesium, brass and bronze alloys.
Ven-Cast™ provides the following benefits:
•improves flowability of the molding sand;
•increases dry strength;
•reduces water requirements;
•develops excellent pattern conformity;
•retains sharp edges of the mold;
•inhibits expansion defects;
•promotes cleaner sand peel;
•has negligible smoke and/or fumes;
•does not waterproof bentonites.
A Ven-Cast™/bentonite (Western and/or Southern) sand system is simple to control – insuring consistent high quality castings.
Ven-Cast™ is usually maintained at 1% to 2% by weight in the sand system. Because such a system is so efficient, special facing sands can often be eliminated. Most foundries will have no need for other additives such as cob wood flour, oat hulls, etc.
Maintenance cost of a Ven-Cast™ system is low and costeffective.
