What is Plastic Injection Molding?


At Premium Parts, we have designed our plastic injection molding processes for quick prototyping and on-demand, mass-volume production. Our parts can serve industrial, commercial, and household purposes.

The injection molding technique involves the infusion of molten resin into a metal die cavity under high pressure. The resin is then rapidly cooled to lower the temperature and aid in forming a solid shape that fits the shape of the die. Once the tooling has been made, the actual injection molding process lasts only a few seconds to mold parts depending on the material, part size, and design complexity.

Plastic injection molding is often reserved for making high-end parts with production-grade materials. Premium Parts can, however, apply low-tooling operations to carry our low-volume production for bridge-to-market, pilot testing, market validation, and other mid-scale operations.  

Our process flow makes your injection-molded parts in 6 key steps, as shown below:

Our Injection Molding Services


Premium Parts offers a range of services under our injection molding solutions. Some of our injection molding capabilities are summarized below:


Mold Making 
Premium Parts leverages digital design and manufacturing solutions like CNC machining and EDM to facilitate mold making. Our high-quality molds can manufacture thousands of quality end-use parts. We also carry out rapid tooling at affordable rates for low-volume production with aluminum molds. 

Insert molding and Overmolding
Make composite parts with our overmolding and insert molding capabilities. Overmolding is applied to making single parts from multiple thermoplastic and elastomeric materials. It involves the molding of a secondary material over a first to compliment performance and functionality.
Insert molding also creates composite parts by molding plastic fragments over pre-fabricated parts with metal materials. Insert molding is the technique applied in making parts like screwdrivers, fasteners, clips, and scalpels that house sharp features but require some grip for safe handling.

On-demand manufacturing and Plastic injection molding 
Our plastic injection molding can make high-quality plastic parts with excellent cosmetic finish quickly and affordably. Once the tooling has been designed and produced, our plastic injection molding can make low and high-volume parts for various prototyping, testing, and end-use applications.

Multi-cavity molding 
We can perform family/multi-cavity molding solutions for making plastic parts. Our family molds will produce two or more different parts of the same material in one injection molding cycle. Easy and efficient for the production of parts with multiple components.
Why Injection Molding?

Excellent quality 
Injection molding captures even the tiniest detail for your part and delivers on functionality and a cosmetic finish. Injection molding can also make plastic parts with complex geometries and dimensional accuracy. 

Scalability and mass production  
Plastic injection molding can make hundreds of thousands of identical parts. It has a high level of repeatability and consistency across manufactured parts. 

Tool life span 
Use your high-quality tooling to make and re-run thousands of parts in multiple production cycles. The tool life span depends on the material, geometry, and production process.

Material diversity and options 
Choose from a wide range of thermoplastic materials to make your plastic prototypes and end-use parts. You can also leverage overmolding and insert molding to make parts from a combination of materials. 

Low-volume manufacturing 
Use custom aluminum tooling to lower costs and run rapid injection molding for prototyping and low-volume production.

Finishing options 
Compliment your part appearance and functionality with the array of finishing options offered by Premium Parts.

Finishing options 


Premium Parts provides an array of finishing services to augment the beauty and cosmetic appearance of your part. We also have finishing options to increase the surface protection of your parts.  


As manufactured 
Parts are left as they are when ejected from the mold. Suitable for parts that will be used in closed areas or parts that make up the non-visible portion of a larger component. 

Media blasting 
Media blasting uses a medium (sand, bead, glass) to create a surface texture on the molded parts. 

Pad printing 
Pad printing is used to transfer logos, graphics, and texts to the surface of the part.

Etching 
Etching can be used when looking to make a marking or inscription on a molded part's surface.

Polishing 
Premium Parts can achieve glossy, semi-glossy, matter, and mirror-like finishing on your part by polishing and sandpapering the part as desired. 

Texturing 
Texturing can enhance grip, grab, and hold functionality for molded parts.

Painting 
Injection-molded parts may be wet-painted, or powder-coated in an array of color and texture-rich automotive-grade paints.

Custom
Choose from an array of custom finishing that is unique or a combination of some standard finishes.
