Key Assembly Technologies & Joining Methods

Mechanical Fastening and Molded Inserts

We integrate features like molded‑in metal inserts, threaded bosses, and handles directly during part production to streamline assembly. These techniques:

  • reduce reliance on secondary tooling and fixtures
  • support automation or manual assembly depending on volume and complexity

Thermal Welding & Adhesive Bonding

We select advanced joining methods such as ultrasonic welding for high‑throughput similar‑material joints, or heat‑staking and structural adhesives for mixed materials or delicate parts, to match your product’s performance and service life. These options ensure reliable assembly even in high‑stress or regulated environments.

Kitting, Sub‑Assembly & Packaged Solutions

Beyond individual parts, we provide finished kits that arrive ready for your line. Our services include:

  • combining formed, machined or sourced components into one SKU
  • applying graphics, coatings, flocking, and other finishes in‑house
  • full pack‑and‑ship logistics, including direct drop‑ship to your customer or end‑user

Our Process for Assembly‑Ready Components

Number 1

Design Collaboration & DFA Review

We evaluate part geometry, joining strategy, and material behavior to prepare components for efficient assembly and high reliability.

Number 2

Manufacturing of Components

Parts are formed, molded or machined and delivered with inserts, features or finishes pre‑integrated to support assembly.

Number 3

Assembly & Finishing

Our team executes the assembly: inserting components, bonding, applying finishes like flocking, conducting inspection, and packaging.

Number 4

Kitting & Logistics

We assemble kits or full products, bundle components, apply tracking/SKUs, and ship directly to you or your customers, reducing your internal handling.

Our Assembly Capabilities Include

  • NPI-formed parts + sourced components: We combine plastics we form in-house with metals, hardware, or packaging you specify.
  • Mechanical and bonded sub-assemblies: Molded-in inserts, glue bonding, and ultrasonic welding.
  • Flocking and finishing: Interior-grade flocking and decorative appliqués enhance performance and aesthetics.
  • Packaged kits & drop-ship fulfillment: Barcode stickers, gel labels, printed boxes—all handled for you.
  • Scalable builds: From single prototypes to thousands of units, our operation scales with your demand.
