This document discusses thermosetting materials and their applications in plastic molding. It notes that thermosetting materials are commonly used in micro molding and other industries. Once heated and hardened, thermosetting materials cannot be remelted or remolded. Their melting points vary, with some having extremely high melting points. Vulcanized rubber, which is harder than natural rubber and cannot be recycled once solidified, is used to make automobile tires and for insert molding due to its strength and insulation properties. Bakelite is commonly used to make colored bangles, bracelets, and artificial jewelry due to its ability to be manufactured in various colors.

2. • Thermosetting materials are one of
the plastic molding tools used in making items
that are applicable to numerous industries,
including micro molding companies. There are
several types and their applications vary.

3. • A thermosetting material (alternatively known
as thermosets, thermosetting resin, or
thermosetting polymer) is a normal liquid
material that hardens irreversibly when
heated. Thermosets have high melting points,
but they get solid after being exposed to a
level of heat. However, once they are
hardened, they can’t be remolded or liquefied
anymore.

4. • Also, the melting points of thermosetting
materials are different. Some have extremely
high melting points, while others have a less-
higher melting point. In cases where they are
overheated, they disintegrate and get
disfigured. This is why delicate and medical
molding processes, such as medical plastic
injection, insert molding, and medical
overmolding injection molding rely
on thermosetting materials‘ behavior.

5. • THis type of rubber is more hardened than
natural rubber. Once it solidifies, it can’t be
recycled. It’s used in the production of several
goods as it has both electrical and thermal
insulation characteristics. It also has good
abrasion properties and it’s not expensive.

6. • Vulcanized rubber is used to make automobile
tires because of its high tensile strength,
which decreases the risk of tire punctures. It is
also used by insert molding suppliers to shield
metal and iron items.
• Bakelite

7. TYPES OF PLASTICS
It also has the unique quality of being able to be
manufactured in various colors, which is why it is
commonly used in the production of colored
bangles, bracelets, and artificial jewelry. You can
also find it in a variety of kitchenware products.
