jewelry mold maker jobs
Looking for jewelry mold maker jobs? Or, in the natural
rubber or silicone rubber industry? In the world of lost
wax casting, this question is hardly an academic one.
The mold material chosen must be up to the task of
turning a single original model into hundreds or even
thousands of wax models for casting, and choosing the
wrong material can lead to some serious hair-pulling in
the jewelry mold maker jobs department.
Why are jewelry mold maker jobs in demand?
There are actually three primary categories of rubber
mold making materials: natural rubber, vulcanizing
silicone rubbers, and room temperature vulcanizing (RTV)
rubbers, a non-shrinking, no-heat option. Each has its
advantages and disadvantages, and as a result, each may
be the best choice in certain situations. The key to
choosing between them is to understand the properties of
all three, and then decide which to use based on what
qualities are most important for a given situation.
jewelry mold maker jobs advantages
Natural rubber's advantages include high tear and
tensile strength and a long shelf life. As the industry
standard for decades, it's also a more familiar material
to many mold makers.
Tensile strength is commonly measured by the number of
pounds per square inch (psi) required to tear a standard
sample. Natural rubber can withstand up to 3,000 to
3,500 psi, while silicone rubbers can handle 1,000 to
1,400 psi. RTVs are the most prone to tearing at 100 to
200 psi. Contact us for more information about jewelry
