Insert Molding Services

Creates Strong Parts

Cost-Efficient Tooling

High-Quality Finishing

Reduced Production Time

Insert molding is a common manufacturing process where the insert is placed into the mold. This placement of the insert can be automated or manual, depending on the production volume of the parts. For high volumes, the placement is typically automated, and for low volumes, it is manual.

Design Guidelines for Insert Molding Services

Our insert molding services allow you to manufacture parts so that they can meet a variety of functional needs. We ensure the quality of your insert molding project with the following molding design needs that are executed in a specific manner.

The Machining

We have vertical machines of wide capacities that are designed to carry out the plastic molding process through insert injection molding, and have a set of design guidelines that are accurately followed by our expert and experienced engineering team. The machines we use for our insert molding have an exceptionally tight tolerance, which ensures that the information on the plastic parts is accurate in plastic injection molding. We know that even a minor misalignment in millimeters can end up causing failure for the product, which is why we ensure no inaccuracy.

The Inserts

There are many different types of inserts used in the designing and manufacturing of molded components. These metal insert in the insert molding is usually made of brass, stainless steel, or the usual steel. The molds are placed vertically in the machine, manually or automatically through the CNC machining. The vertical position is to make sure that the mold stays safely in its place during the process of insert molding with the help of gravity. Now the molten plastic is poured into the mold, and the mold is closed.

Thread Options

Thread options allow the manufacturer to place pipes, screws, or anything else into the mold at specified locations. They aim to ensure that the mold does not make the product insert. As the product needs to be connected to external conduits in many ways, the mold will allow the final product to stay functional and useful.

Injection Molding Plastic Materials

tolerance

For our insert molding services, we are typically able to maintain a machining tolerance of +/- 0.003 in. (0.08mm) with an included resin tolerance that can be more than but not less than +/- 0.002 in. /in. (0.002mm/mm).

Finishing

We offer multiple finishing options to complete the products made with the insert molding process. You can choose from any of the following depending upon your application’s requirements:

Standard Finish
Interior, non-cosmetic finish according to the geometry of the mold.

SPI Finishes
Range of SPI finishes from Grade 3 diamond / high polish to 320 stone low polish. These Finishing options include SPI A-1, SPI A-2, SPI A-3, SPI B-1, SPI B-2, SPI B-3, SPI C-1, SPI C-2, SPI C-3, SPI D-1, SPI D-2, and SPI D-3.

Threaded Inserts
We can install the most commonly used and popular standard inserts in UNF and metric sizes.

As Molded
As the name suggests, the mold will remain ‘as it is’ – without any secondary texturing or polishing.

Mold Texturing Creating textures on the molds so that it shows on the final product. This finishing option includes matte, swirls, patterns, and lines.

Laser Engraving Engrave part numbers, designs, logos, or any other specified printing onto your parts.

Pad Printing Application of an ink-based design to the surface.

Painting Painting the surface with standard colors or Pantone matching, including Primer and topcoat. Masking available; EMI (copper) paint.

What is Insert Molding?

Insert molding refers to the process of manufacturing plastic parts around other, non-plastic parts, also known as inserts. The inserted component is typically a simple object, such as a thread or rod, but in some cases, inserts can be as complex as a battery or motor.

Once the insert is placed, the molten plastic is injected such that it surrounds the insert to form a tight and secure bond. As a result, a single joined piece of sturdy, long-lasting part is formed.

why you should choose CNC machining

  • Creates Strong Components

Injection-molded parts are manufactured in a mold cavity that does not leave room for any potential dimensional changes, guaranteeing that every part is strong and durable.

  • Reliable and Consistent Results

The insert molding method produces perfect products every time as it eliminates the need for manual after-production trimming and finishing.

  • Material Variety

The process of insert molding offers a wide selection of materials to help you choose the one that fits your needs.

  • The Complexity of part design

Injection molding can handle the production of extremely complex parts while ensuring uniformity and accuracy.

F.A.Q.

Overmolding refers to the process when plastic is molded over another molded part. The first component is made inside an injection mold, and it is then placed into a second mold to add the over-molded material. On the contrary, Insert molding refers to combining other parts, particularly metal parts, directly into the injection-molded product.

We want to evaluate the part using a 3D file output from any number of designing software packages. You will also have to share the material and other estimated information, including the timeframe, budget, and so on.

The material to be used for your project depends totally on the end-use application for your part.

Depending on size and complexity, we take from 4 to 12 weeks generally to complete an insert mold project.

Insert molding is suitable for plastic over other materials. If your product has a non-plastic component, then insert molding is the perfect solution for you.
