Our Advanced Injection Molding Options

We can produce thousands of parts to pace up your product development cycle. You can choose from a large variety of materials. We keep over 100 plastic resins materials in the inventory to kick start the production. For molded end products, we have many finishing options. Our injection molding capabilities are plastic molding, insert molding, over molding, and family molding.

We employ finest thermoplastic materials to produce superior quality injection molded parts. We scientifically execute whole process from gathering requirements to design evaluation, die and mold production and up to final product.

In insert molding, we use a pre-manufactured part (mostly a metal) which is inserted into a mold. To get the final product, preformed mold is over molded with required thermoplastic resin. Availing our insert molding services, you can have exceptional quality products.

In over molding process, we can mold a thermoplastic material into a second thermoplastic or liquid silicone rubber material. Which provides us the ability to achieve required product attributes and functionality.

When customer demands speedy project deliveries then we use family injection mold. It gives us the ability to manufacture multiple parts with the same material in a single cycle. This injection molding technique has more than one cavity cut into the mold. Each cavity can make different part.

Materials Options for Injection Molding Services

We can process numerous plastics and polymers. We have in-house capacity of a large collection of different injection molding materials. That includes PPS, PP, POM, ABS, C-GF, HDPE, LDPE, PBT, TPV, PC, POE, PMMA, PA66, PA-GF, PS-PPE, TPE, and TPU.  We can process customers provided materials too.

Different Surface Finishing Options

With various surface finishing options, Prototool can make your injection molded products look and work better. Different finishing methods can be chosen for different needs. Below are some of the techniques we use to refine your injection molded parts:

Bead Blasting

Bead blasting is a way in which injection molded parts are cleaned and refined. It uses high-pressure glass or steel beads to blast the surface into a uniform, matte finish. It's a good method if you want to look uniform and professional.

Pad Printing​

The multi-functional pad printing process is excellent for applying company logos and brand names, as well as all kinds of decorative designs, to the surface of injection molded products. This is a good choice if you're looking to customize your own personalization and increase the attractiveness of your parts.


To raise the roughness of injection molded parts, our surface etching method is used. By chemical or physical means, we can create texture and finish that meets your needs.

Laser Finishing

Injection molded parts can undergo laser surface treatment. This is a very exacting thermal process. It engraves fine lines and pictures, firm company taglines or little logos with great precision. It can heat up to several hundred degrees Celsius by absorbing the light on its surface layer.

Industrial Application of Injection Molding

Due to its manufacturing friendly properties, injection molding is being harnessed in many sectors in the world. It is employed in almost every industry in one or the other way.
