Secondary Operations Services

Assembly & Kitting

From manual assembly to automated manufacturing cells, Aroplax provides complete product assembly, insert installation, hardware integration, sub-assemblies, kitting, and final product assembly. Our goal is to deliver production-ready components that reduce handling, improve quality, and simplify our customers' manufacturing and supply chain operations.

Custom Labeling & Packaging

Aroplax works collaboratively with our customers and packaging suppliers to develop packaging solutions that protect products, improve manufacturing and shipping efficiency, and support retail or distribution requirements. Services include custom labels, barcoding, lot traceability, instruction inserts, private labeling, custom corrugated packaging, retail-ready packaging, and custom protective inserts designed specifically for each application.

Ultrasonic Welding

Aroplax performs ultrasonic welding for multi-piece plastic assemblies using custom fixtures and tooling to ensure consistent weld quality. Using high-frequency vibrations and pressure, our team can melt and fuse delicate plastic parts and high-tolerance components.

Drilling, Tapping, & Machining

We provide secondary machining operations including drilling, tapping, reaming, milling, trimming, and other custom modifications when required. Whenever possible, we engineer tooling to mold these features directly into the part, reducing secondary operations, lowering cost, and improving consistency.

Aroplax offers flexible inventory management programs tailored to each customer's production requirements. Whether manufacturing larger production runs with scheduled releases, maintaining customer inventory at our facility for ongoing shipments, or replenishing inventory as stock levels change, we work closely with our customers to improve supply chain efficiency, reduce inventory carrying costs, and ensure product availability when it's needed.

Frequently Asked Questions

Are secondary operations available without injection molding?

No. Secondary operations are offered as part of Aroplax’s full-service injection molding offerings rather than a standalone service.

Does every injection molding project need secondary operations?

No. Whenever possible, we try to eliminate the need for secondary operations by manufacturing features directly onto the part so post-production machining, assembly, and other operations aren’t needed.

How do Aroplax secondary operations services compare to other injection molding companies?

Many manufacturers rely on outside suppliers for value-added operations after molding. Aroplax performs a wide range of these services in-house, allowing us to maintain greater control over quality, scheduling, lead times, and overall manufacturing efficiency. Keeping these operations under one roof also reduces transportation, handling, supplier management, and the risk of quality issues between multiple vendors.

What secondary operations does Aroplax offer?

With our full-service precision injection molding services, we also offer secondary operations, including:

Ultrasonic welding
Drilling, tapping, and machining
Assembly and kitting
Warehousing and inventory management
Custom labeling and packaging

Why is Aroplax preferred for precision injection molding and secondary operations?

Aroplax provides a true single-source manufacturing solution, combining injection molding with value-added services such as assembly, machining, ultrasonic welding, packaging, labeling, and inventory management under one roof. This reduces suppliers, handling, lead times, and overall manufacturing costs while improving quality and production efficiency. Our engineering team also looks for opportunities to automate, integrate, or eliminate secondary operations through better part design and tooling strategy whenever practical.
