High-quality customized plastic shell mold parts injection molding
services
Plastic shell mold Parts Injection molding is a manufacturing
process used to produce plastic parts with complex geometric
shapes. It
involves injecting molten plastic into a precision mold cavity,
where it solidifies to form a specific shape. Plastic shell mold
parts are
commonly used in a wide range of industries due to their light
weight, durability, and cost effective nature.
What is injection molding?
Injection molding is a manufacturing process in which molten
plastic is injected into a metal mold. The plastic molded part is
then cooled
and ejected from the mold cavity using a pin.
Plastic mold manufacturing
Plastic injection molding is an efficient manufacturing method and
manufacturing process, which is widely used to manufacture plastic
parts
with various specifications and precision. At JYH, we use advanced
machines and a team of experienced engineers to melt plastic
particles
and inject them into molds under high pressure. The process ensures
the production of high-quality plastic parts and products suitable
for industrial molding applications.
The temperature in injection molding plays several important roles
in ensuring quality control:
| Material Flow and Fill: |
The temperature of the molten plastic material affects its
viscosity, or flowability. Higher temperatures reduce the
material’s viscosity, allowing it to flow more easily into the mold
cavities during the injection phase. Proper temperature control
ensures optimal material flow and fill, preventing issues such as
short shots, flow marks, or incomplete part filling. Temperature
control also helps ensure consistent material properties and
dimensional accuracy in the final parts.
|
| Melting and Homogenization: |
The temperature must be carefully controlled during the melting
process to ensure complete melting and homogenization of the
plastic material. Insufficient melting can result in unmelted
particles or inconsistent material properties, leading to defects
in the molded parts. Proper temperature control during the melting
phase ensures uniform melting and mixing of additives, enhancing
material homogeneity and the overall quality of the molded parts.
|
| Cooling and Solidification: |
After the molten plastic is injected into the mold, temperature
control is crucial during the cooling and solidification phase.
Proper cooling rates and uniform cooling help prevent issues such
as warping, shrinkage, or part distortion. Controlling the
temperature allows for consistent solidification throughout the
part, ensuring dimensional stability and minimizing internal
stresses. Temperature control also affects the part’s crystallinity
and microstructure, which can impact its mechanical properties.

Plastic shell mold parts are widely used:
- Consumer electronics: as a housing for smartphones, laptops and
other electronic products.
- Automotive industry: For internal and external components,
including dashboards and control panels.
- Medical devices: enclosures for diagnostic devices and portable
medical tools.
- Telecommunications equipment: enclosures for routers, modems, and
communication equipment.
- Toys: Structural parts assembled as toys.
The key steps of the injection molding cycle are:
Clamping:The two sides of the mold are closed and clamped shut.
|
Injection:The material is fed into the machine and pushed towards the mold.
While this is happening, the material is melted by heat and
pressure. The plastic is then injected into the mold — this is
called the “shot.”
|
Cooling:The plastic in the mold cools and solidifies into the shape of the
part.
|
Ejection:After the part cools, it is ejected from the mold.

Injection Moulding Process:
Plastic injection moulding allows to produce large numbers of parts
with great accuracy and A quick cycle times from multi-cavity
tools.
The process of injection mould involves a certain amount of polymer
materials being heated, melted, and injected into a mould under
high pressure. Further into the process, main units of the
injection moulding machine are:
- feed hopper;
- heated barrel;
- crew (known as the injection unit);
- clamp unit (which holds the mould together under the injection
pressures);
- ejection unit (which removes the part from the mould).
According to the structure and technical analysis of the shell, the
shell has an outer groove and an inner groove structure, and the
two
groups of inner groove are located in the fixed die part and the
moving die part respectively. The mold structure needs to use
external core
pulling and internal core pulling mechanism to form grooves to meet
the molding requirements of the shell.
Excellent efficiency and fast manufacturing:
Plastic injection molding is the most common and successful type of
injection molding for many different reasons, which makes it ideal
for many different businesses.
It is also more efficient and, therefore, it has a larger
production yield. In addition, it is more cost-effective. The
complexity of the design and the requirements of the mold directly
affect the yield of the product. However, the cycle is usually
between 15,000 and 70,000 seconds.
