A processing method which forms
the rubber in the mold by the application of pressure and heat
which shapes and cures the parts.
Injection Molding
A repetitive process in which plastic is melted and injected
into a mold cavity where the article is cooled down. After
cooling, the mould opens and the article is ejected.
Blow Molding
Process of inflating a hot, hollow, thermoplastic preform or
parison inside a closed mold so its shape conforms to that of
the mold cavity. A wide variety of hollow parts, including
plastic bottles, can be produced from many different plastics
using this process.
Rotational Molding (rotomolding)
In rotational molding, or rotomolding, a product is formed
from fine powder within a closed mold, which is rotated in a
heating chamber and then a cooling chamber. While the mold is
slowly turning and tumbling, it is heated by forced hot air in
an oven. As the mold wall heats, the resin begins to stick to
the inside of the mold forming a hollow part.
Compression Molding
Technique for molding thermoset plastics in which a part is
shaped by placing the fiber and resin into an open mold cavity,
closing the mold, and applying heat and pressure until the
material has cured or achieved its final form.
Insert Molding (overmolding)
Insert molding is an integral process for directly producing a
complete product by molding the resin material together with
metallic, fabric, and resin components placed in the die. Unlike
the conventional production process that separately assembles
(inserts or adheres) components and accessories, strength and
durability are much higher.
Dip molding
Process where a mold or part is dipped into a polymer for dip
molding or dip coating a part. This dip molding process is used
to make items such as surgeons gloves and hand tool handles.
Transfer Molding
Resin transfer molding (RTM) is a liquid molding process that is
commonly used in the aerospace and automotive industries. In
the RTM process, a resin is mixed with a hardener and then
injected at low pressure into a mold containing dry fibers.
Structural Foam Molding
Structural foam molding is a type of injection molding process commonly
used for parts that require thicker walls than standard injection
molding. Introducing a small amount of nitrogen or chemical blow agent
into the plastic material allows for the creation of the thicker
walls. Foaming occurs as the melted plastic material enters the mold
cavity. |
