What is the Plastic Injection Molding Process?
Injection molding is a manufacturing solution for creating custom
plastic parts with fast turnaround times. Before mass producing
your custom plastic parts, you must first customize injection
moulds for your production line. The molten thermoplastic is then
injected into the mold to form your plastic parts. Inside the mold,
the plastic cools and hardens into your custom components.

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.

Injection Molding Processes
Plastic Injection Molding Plastic injection molding is a versatile manufacturing process that
utilizes high-pressure injection of molten plastic into a mold
cavity to produce a wide range of complex and durable plastic
products. This is an ideal process for producing large volumes of
standardized parts with excellent mechanical properties. | Insert Molding Insert molding involves the injection of molten thermoplastic
around a pre-placed insert to create strong, durable parts. This
technique offers advantages like reduced assembly time, improved
product reliability and the ability to combine multiple materials
in a single part.
|
Overmolding Overmolding is a process in which multiple shots of thermoplastic
are injected over or around a substrate to create highly
customizable parts. This technique offers versatility and
customization options, allowing for the creation of complex and
multi-material products with enhanced performance and visual
appeal.
| Micro Molding Micro molding is a specialized variation of the injection molding
process used to produce small parts with complex geometries. This
process allows for the creation of extremely small shot weights,
making it a popular option for medical devices, electronics and
automotive applications. Micro molding can produce components as
small as 0.00025 cc with high quality and repeatability and is
compatible with a variety of materials such as PEEK, ABS, Pebax and
polypropylene. |
Custom Plastic Injection Molding Materials
Acrylonitrile Butadiene Styrene (ABS).A common thermoplastic used for products that do not require
chemical, electrical, or UV resistance. ABS is a flexible and
lightweight material with good impact strength and durability. Many
everyday objects use ABS custom injection molded parts, such as
children’s toys, components in household appliances, and automotive
parts.
Low-Density and High-Density Polyethylene (LDPE and HDPE).As one of the most versatile thermoplastics, LDPE and HDPE have
high tensile strength, impact resistance, and moisture resistance.
HDPE is a material used in a range of consumer and industrial
products, while LDPE is a softer version popular in consumer and
industrial production.
Polycarbonate (PC).As a transparent, lightweight material, PC is a durable alternative
to glass. With high durability and extreme impact resistance, many
demanding applications use PC, including bulletproof glass.
Polyamide (Nylon).Nylon offers excellent electrical properties, strength, and
resistance to heat wear, and chemicals. Applications in the medical
and automotive industries often use nylon for custom plastic
injection molded parts.
High Impact Polystyrene (HIPS).As a versatile, impact-resistant, and economical plastic, HIPS
consists of crystal styrene and rubber. With non-toxic properties,
HIPS is ideal for food-grade components.
Polypropylene (PP).With excellent chemical and stress resistance and high impact
strength, PP is a robust plastic with a high melting point. PP is
often used as a food-grade polymer in the food and beverage
industry.
Why Choose An Injection Molding Service?
The plastic inside the patterns of an injection mold is compressed
and forced more firmly into the walls due to the high pressure
applied to
the mold. Plastic injection molding is the only molding process
that, in comparison to other molding processes, can successfully
combine all
of the part’s intricacies. This indicates that there should be no
restrictions placed on the amount of detail that should be included
in the design.
Plastic molding can produce detailed and extensive details without
incurring high costs thanks to high pressure, which is another key
contribution that high pressure brings to the process. The use of
injection molding makes it possible to produce elaborate designs
while maintaining a cost-effective manufacturing technique.
Prototype Injection Molding Considerations
Subject | Consideration
|
Tool Life | Tooling used for prototype molding applications is generally made
of softer materials and thus will wear out sooner than molds made
of tougher material.
|
Mold Texturing & Polishing | Texturing and polishing of prototype molds can be performed;
however, the effect is likely to wear out sooner due to the softer
tooling used and may not justify the increased cost. Typically we
recommend B to D SPI finishes for prototype molds.
|
Gating Methods | Gates may be constrained to edge, direct & fan techniques. Gating
that requires high shear or hot runners is better suited for Bridge
or Production tooling.
|
Mold Classes | Class 105 & 104 molds are the most suitable for prototyping molding
runs and are typically made of Aluminum or Mild Steel. Projects
requiring class 103,102 or 101 molds may be better suited for other
tiers of production and be made of higher tier materials.
|
Material Selection | All injection molding materials we offer are available for
prototype mold applications. That said, abrasive materials such as
glass-filled ones may result in increased wear on a prototype
tool's life.
