Injection Molded Part Assembly & Kitting

Assembling of plastic injection molded components can be done by several different methods.  The following four are the most common assembly methods:

  • Solvent and Adhesive Bonding
  • UV Bonding
  • Ultrasonic Welding
  • Mechanical Fastening

Injection molded parts kitting consists of a post-molding operation that puts together a range of products.  Having these pre-built batches of product ready to go remains a cost effective manufacturing solution instead of building these out every time an order is placed.   With large production the kitting time will be further reduced because of the streamlined approach.

More than just a supplier, the Crescent team is here to provide the most comprehensive kitting, assembly, and value added solutions for you. By investing so heavily into our post-molding capabilities, we have the ability to be a single source partner for you and offer competitive pricing by taking some of the workload off your plate. Whether you need assembly in-house or sending products to a different supplier, our injection molding part assembly and fitting expertise cuts down lead time and allows the option for JIT delivery of your fully assembled products.

Insert Molding and Overmolding for Assembled Injection Molded Products

You can achieve an assembled component during the injection molding phase by using the techniques of insert molding or overmolding.   Insert molding often combines a metal insert placed in the injection mold so that the molten plastic flows around the insert, creating a mechanically bonded single component.

Overmolding consists of injection molding one base layer and molding over the base layer to make one completed part. The outer layer is an elastomer material to give the product pliability and texture.
