Unitedparts’Plastic Injection Integration Services

Plastic injection molding is a mature and highly efficient forming technology, with most molded parts ready for direct use after production.
Unitedparts provides comprehensive injection molding integration services, covering single-shot molding, two-shot molding, insert molding, and ultrasonic welding. For insert molding projects, we can also coordinate the required metal components, enabling plastic parts and embedded inserts to be completed in parallel.

Beyond injection mass production, Unitedparts integrates downstream operations such as plastic-to-metal assembly and multi-component packaging.

Unitedparts’Plastic Injection Integration Flow

All stages from molding and assembly to packaging are centrally managed by Unitedparts, forming a complete and coordinated production workflow. This integrated approach ensures consistency in both quality and process control, resulting in stable and reliable product delivery.

Unitedparts’Plastic Injection Integration Scope

	Features	Typical Applications	Materials
Injection Molding	• Single material injected into the mold and formed in one cycle • Most common process with high production efficiency	• General housings • Home appliance enclosures • Automotive interior components	General-purpose plastics: PE, PP, PS, PVC Engineering plastics: PC, PA (Nylon), POM, ABS, PMMA High-performance materials: PEEK, PA+GF, TPE Unitedparts commonly used materials: FR3005, PP, PVC, PA, PA+GF, ABS, TPE
Two-shot Molding	• Two different plastics were injected sequentially into the same mold • Enables integrated structures combining functionality and visual design	• Handles (machine tools, bicycles) • 3C products • General housings • Buttons
Insert Molding	• Metal or other components placed into the mold prior to injection • Plastic encapsulates inserts to form a single integrated structure	• Electrical connectors • Components with metal inserts
