Insert molding is one the popular molding methods, which are widely used to make insert-molded couplings, filters, threaded fasteners, and electrical components in a wide range of industries. Insert molding preserves the strength and functionality of metal parts by embedding these elements in more economical and efficient plastic parts, giving you the best of both worlds.

What is Insert Molding & Insert Molds?

Insert molding refers to a molding method in which one or more previously fabricated molten plastic resins encapsulated and injected into a insert mold, and the molten material is bonded and solidified to form an integrated single finished part. The Insert mold components are usually simple objects made of metal or different types of plastic, metal materials are used to improve strength and electrical conductivity, while plastics are used to improve wear resistance, tensile strength and weight. Plastic insert molding can help save costs and reduce production time by eliminating the need for secondary operations such as soldering, connectors and adhesives, and is ideal for increasing component strength and reliability.

• Reduce part size and weight, improve component reliability, strength and structure
• Insert molding allows retention of essential metal elements within a plastic part
• Strengthen fastening areas and eliminate creep potential
• Enhanced design flexibility by integrating features not possible with plastic alone
• Insert molding saves those assembly and labor costs

Insert Molding Applications:

• Electrical components: Screws, studs, contacts, clips, spring contacts, pins, surface mount pads, and more
• Automotive parts: Insert-molded couplings, threaded fasteners, filters
• Medical products: Plastic parts with metal parts are widely used in medical and surgical equipment
• Industrial and consumer goods: Insert molding is used in many industries such as electronics, HVAC systems, etc.
• Defense and Aerospace: Insert molding for aircraft interior, control, communication and guidance/navigation components.
