Overview: Plastic Injection Molding
Injection molding plastic is a manufacturing process that melts raw plastic pellets and injects the liquid resin into a metal mold under high pressure. Once the plastic cools and solidifies, the mold opens to release the finished, perfectly formed part.
Flexibility: Manufacturers can choose the plastic injection mold design and type of thermoplastic that's used for each component. This means the injection molding process can produce a variety of components, including parts that are complex and highly detailed.
Efficiency: Once the process has been set up and tested, injection molding machines can meet high volume production. Using electric injection molding machines also makes the process relatively energy efficient.
Consistency: If the process parameters are tightly controlled, the injection molding process can produce thousands of plastic parts quickly at a consistent quality.
Cost-effectiveness: Once the mold (which is the most expensive element) has been built, the cost of production per component is relatively low, particularly if created in high volumes for mass production.
Quality: Whether manufacturers are looking for strong, tensile or highly detailed components, the injection molding process is able to produce them at a high quality repeatedly.
Common types
Thermoplastic injection molding
This is the most common process you'll see in injection molding. It involves hot plastic resin entering a mold before cooling to create the finished product.
Overmolding
Overmolding allows parts to be made with multiple materials. It's commonly used to make products more flexible or easier to grip.
Insert Molding
A specialized process that involves inserting a component (usually metal) into the mold before liquid resin is added. This creates a single, integrated part that is typically stronger and more durable than those made without an insert.
Two-shot molding
Like overmolding, two-shot molding makes it possible to manufacture products with multiple materials. In terms of production volume, two-shot molding is best for high-volume runs, while overmolding may be preferred for low-volume runs.
Material Compatibility
Our plastic injection service team selects the appropriate material based on mechanical strength, heat resistance, impact resistance, transparency, flexibility, or chemical stability required by your application.
