Insert Molding

The custom insert molding process consists of several key steps:

• Insert Placement: A metal, plastic, or composite insert is precisely positioned within the mold cavity.
• Plastic Injection: Molten plastic is injected around the insert, encapsulating it within the final part.
• Cooling and Solidification: The plastic material cools and solidifies, bonding seamlessly with the insert.
• Part Ejection and Quality Inspection: The finished part is ejected and undergoes strict quality checks for strength and accuracy.

This single-step molding process eliminates the need for secondary assembly, making it an efficient solution for complex insert molded components and parts.

At UGP Plastics, we utilize cutting-edge molding technology to manufacture high-quality insert molded components and parts for various applications. Our advanced capabilities include:

• Threaded Insert Molding: For those situations where you need to have some kind of a fastening point, it’s ideal to put metallic threads into plastic so that in products which are used frequently or which are taken apart and put together fairly often, you get a stronger and more lasting connection.
• Multi-Material Insert Molding: When combining different materials, for example, rigid plastics, soft elastomers and metal inserts, it is possible to create parts that have improved functionality, impact resistance and user comfort.
• Overmolding with Inserts: We offer soft touch coatings or ergonomic grips integrated into metal or hard plastic inserts – medical instruments, power tools, and automotive controls.
• High-Volume & Low-Volume Insert Molding: We offer our plastic insert molding services across multiple production levels, including prototypes, low-volume batches and high-volume manufacturing based on your project needs.

How does insert molding compare to overmolding?

Insert molding is a process where pre-formed inserts are placed inside a mold before plastic injection, whereas overmolding is a process of molding one material over another to form a multi-layered product.

Can UGP Plastics handle both low-volume and high-volume insert molding?

Yes! We offer low-volume insert molding for prototypes and small production runs, as well as high-volume insert molding for large-scale manufacturing needs.

How precise is the insert molding process?

We achieve high precision and tight tolerances combined with consistent quality in all our manufactured parts thanks to state-of-the-art equipment and process controls.

What types of inserts can be used in the molding process?

We can mold around metal, ceramic, plastic, fibre reinforced materials, electronic components etc. to meet specific industry needs.

How does insert molding improve product strength?

Using inserts at moulding time improves the part’s structural strength, removing potential weak points that additively assembled parts might have.

What industries use insert molding?

Industries such as automotive, medical, aerospace, electronics, and industrial equipment rely on insert molding for high-strength, lightweight, and precision-engineered parts.
