Common Overmolding Materials and their Advantages

Plastic Injection Molding Blog|

While overmolding is a versatile manufacturing process, it
is important to consider and understand the requirements needed for every part
created. Overmolding material compatibility is the most important consideration
because if the materials used are not chemically and thermally compatible, the
product may be deformed and have poor performance.  

Materials for Overmolding

Overmolding allows manufacturers to create strong, durable,
and consistent parts by combining multiple materials. There are many combinations
of materials that can be used to create any one part. Luckily, there are many
resins common in the industry that each have their own advantages.  

High Density Polyethylene (HDPE)

HDPE is one of the most versatile and popular plastics used in the industry. Its properties are great for large parts that require outstanding physical performance like corrosion-resistant piping, plastic lumber, and many other products. HDPE has many other benefits that make it an ideal material including:

Excellent strength but very lightweight Impact and weather-resistant to keep product quality intact in harsh environments Very malleable and can be easily molded into any shapeGreat for replacing heavy materials and sustainability value.

Acrylonitrile Butadiene Styrene (ABS)

ABS is an industry chosen material in overmolding processes to reach specific requirements in applications such as consumer electronics or automotive parts. […]
