Advantages of Overmolding (3)

  • Combined Plastics for Overmolding

    It uses two or more plastics to create overmolded parts, which adds more possibilities to the design work. Being a molding parts manufacturer, we often apply these overmoled parts

  • Less Labor-Overmolding

    The process of overmolding is semi-automated by applying the robotic arms. It greatly reduces the labor cost.

  • No Assembly Required-Overmolding

    It does not need to assemble the parts as it produces the molding parts from different molds. It reduces the time and cost we spent.

Overmolded Parts

The overmolded parts can be applied in various industries.

Related Processing that Beska Offers (3)

  • Insert Molding

    It is another variant of injection molding. It is similar to overmolding. What makes insert molding different from it is that its substrate is a metal part.

  • Liquid Silicone Rubber Molding

    LSR molding refers to creating the molding components by using liquid silicone. The finished parts are recyclable.


  • Plastic Injection Molding

    Injection molding is a cost-effective technique to make plastic components with high volume. It involves mold designing and making. That’s why the cost of injection molding is much higher for low-volume production.

Beska’s Workshop

Surface Treatment for Prototype CNC Machining Parts

At Beska, we get our own surface finish workshop to serve  different needs of the clients.

Quality Checking for Custom CNC Machining Parts

There are multiple quality checkings on the finished parts, which can ensure the quality of your project.

Packaging for Prototype CNC Machining Parts

At Beska, packaging is also customable. We create the parts accordng to your requirements.

How to Ensure the Quality of the Finished Components?
Quality Checking

We usually use various quality inspection tools to ensure quality including CMM, height gauge, vernier caliper, etc. Before delivery, the quality checking department will do multiple inspections from raw materials, in-process, and final checking.

What Is Insert Molding
What Is Overmolding?
The Basics of Overmolding?

Overmolding is a two-step process that uses two or more plastics on top of each other to form an overmolded part.

The two steps of overmolding involve the fabrication of two parts: the substrate and the second layer. In the first step, we make that substrate first. After it is cured, we make the second layer directly on top of the substrate to form a single part. The common application of overmolded parts consists of cell cases, silicone handles, and toothbrushes. The common plastics are ABS, HDPE, PEEK, Nylon, PC, PE, TPU, PMMA, POM, etc.


What Is the Difference between Insert Molding and Overmolding?

Both overmolding and insert molding are variants of injection molding. The difference between them is that the substrate is different. The overmolding applies plastics as the substrate while insert molding uses metals.

Can You Overmold Polycarbonate?

Yes, we can overmold polycarbonate. At Beska, the common plastics used for overmolding are ABS, PMMA, POM, HDPE, PC, PE, PEEK, Nylon, etc.

Do You Provide Plastic Overmolding Design?

No, we don’t provide design. We only offer engineering suggestions and solutions.
