Insert Molding Services
Elimold is an ISO 9001:2015-, 13485:2016-, 14001:2015-certified manufacturer of insert-molded parts and assemblies for demanding applications. Regardless of design complexity, we can turn around products that fit, form, and function as intended on time and within budget.
High Precision and Consistency Insert Molding
Our cutting-edge insert molding solutions use a unique combination of process optimization and robotic automation to produce parts with an extremely high level of consistency. Whereas the competition races to embrace insert-molding solutions, Elimold leads the industry, having replaced the operator handloading and removing of an insert with the loading and removing of those inserts by precision robotics. The introduction of and expertise in the use of this automation minimizes the variables that affect final part quality by ensuring a consistent, reliable, and repeatable process.
Elimold’s capacity demonstrates our core expertise in injection molding. From the simplest geometries and lightest-weight components to the most complex shapes and 20-pound parts, we have the experience to manufacture the parts you need. With a clamping force capacity of 40 to 2,200 tons, we will meet the force requirements of your project.
Insert Molding Solutions - High Production Efficiency
Insert molding is typically characterized by molding these components, referred to as “inserts” directly into a part.Insert molding is an injection molding process used to insert metal parts into plastic to create a final plastic component. There are 2 basic steps of this process: Firstly, getting ready the molding insert and loading it onto the mold before molding. Secondly, injecting the molten plastic into the cavity, cooling down, and taking out the final plastic component. Applications for insert molding are wide. Due to the inserts can be just about anything, from alloy threads to electrical contacts, the application possibilities are seemingly endless. It is important to understand the insert molding process, then design the part correctly to optimize the production process. Benefits include lower costs by eliminating handling the part a second time in the secondary department and a part that has greater function that plastic alone. Products that are candidates for metal replacement can still have performance strength utilizing insert molding at critical design features.

Finishing
Standard Finish
Interior, non-cosmetic finish according to the geometry of the mold.
Threaded Inserts
We can install the most commonly used and popular standard inserts in UNF and metric sizes.
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.
Mold Texturing
Creating textures on the molds so that it shows on the final product. This finishing option includes matte, swirls, patterns, and lines.
As Molded
As the name suggests, the mold will remain ‘as it is’ – without any secondary texturing or polishing.
Painting
Painting the surface with standard colors or Pantone matching, including Primer and topcoat. Masking available; EMI (copper) paint.
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.
Insert Molding Benefits
Recently, insert molding has changed certain industrial practices. Many industries are replacing metal parts with plastic ones because plastic is less expensive, resistant to corrosion, durable, and lightweight compared to most metals. Here are the benefits of insert molding:
- Durability: Insert molding offers high precision and enhanced product designs compared to other molding processes. Plastic parts with integrated components are more reliable and robust.
- Efficiency: Insert molding does not require separate assembly, reducing the risk of manufacturing errors. Because the insert is integrated into the molding step, it saves time and labor costs, increasing the efficiency of your entire operation.
- Cost-Efficiency: Insert molding is a cost-saving process since it allows the use of less expensive thermoplastic resins, which are more affordable than metals. It also minimizes labor costs and requirements for specialized assembly equipment.
- Lightweight: Plastic parts are generally 50% lighter than metal but are comparable in terms of strength. This has made many industries opt for plastics to replace metals. The lighter weight contributes to better fuel efficiency in automotive components and easier handling for surgical equipment.
- Size: Insert molding allows the production of smaller and thinner parts without sacrificing performance and durability.
- Material Variety: Insert molding uses a variety of common engineering thermoplastics including Nylon, PBT, PEI, PC etc. Many of these plastics are recyclable throughout their life cycle. They are also durable, versatile, and ideal for various consumer and industrial products.
- Design Variety: The process also allows different types of designs and shapes, expanding possibilities for engineering and design across many fields.
