Several roadblocks have been preventing successful permanent mold casting of magnesium, the most important of which is a lack of suitable mold coatings.
In the absence of a satisfactory, ready-made mold coating, older research was consulted to determine that boron nitride might be a suitable material.
Earlier research also suggested the factors that would need to be optimized in the use of the coating--slurry dilution, mold temperature on application and final thickness of the coating.
Designs and builds injection molds primarily for thermoplastics.
Designs and manufactures high-precision and high-production steel injection molds. Insert, automatic unscrewing, and encapsulating molds.
On one hand, researchers know that harm can come from ingesting large amounts of mold in food or by inhaling high levels of mycotoxins--the toxins produced by a fungus--at some work sites.
That's why bodily injury claims based on mold exposure need to be examined on an individual basis, he said.
Most problems are small and easy to correct, but Dearborn says that the news about toxic molds has led to some hysteria.
"There are hundreds of species of molds, and the prudent approach is to avoid a moldy environment and to keep ahead of it." CONTACT: Toxic Mold and Tort News Online, www.toxic-mold-news.com; Toxic Mold Resource Center, www.geocities.com/toxicmolds.
Custom and stock blow molds of various shapes range from 0.5 oz to 10 gal.
Blow molds for 20-ml to 360-liter containers and specialty parts.
But exposure to other types of mold results in allergic reactions that are of less concern for a healthy individual.
However, if a person has a compromised immune system or has pre-existing dangerous sensitivities to certain allergens, an exposure to even the mildest levels of mold can cause a reaction that can be life threatening.
It is fairly well established that mold can trigger allergies and aggravate asthma, but other reported health effects, such as neurological and gastrointestinal symptoms, are less certain.
One of the key difficulties in such studies is that there's no method to measure mycotoxins--secondary metabolites produced by certain mold species under certain conditions--in home environments.
