Our Finishing Line
From injection molding through assembly, finishing and packaging, PPI integrates the secondary operations required for your project. Our goal is to deliver molded components, technical subassemblies or finished products ready to enter your production or logistics flow, reducing additional handling, coordination and supplier management.
Integrated Manufacturing
One Partner for More of Your Manufacturing Process
Producing the molded plastic component is often only one stage in delivering the finished product.
Assembly, accessory integration, marking, packaging and logistics preparation all require additional coordination, quality control and material flow management.
PPI integrates these operations directly into the manufacturing process, helping customers simplify project management and reduce the number of suppliers involved.
With one dedicated point of contact, your project can be managed from product engineering and injection molding through assembly, finishing, packaging and delivery.
An Integrated Manufacturing Flow
Assembly Solutions
Assembly Methods Matched to Your Product
Our teams perform different assembly operations depending on the product's technical and functional requirements. The appropriate assembly method is selected based on part design, production volumes, expected performance and product lifecycle requirements.
Screw Fastening
Screw fastening provides a durable mechanical assembly while allowing components to be disassembled when maintenance, servicing or part replacement is required.
Snap-Fit Assembly
Snap-fit assembly provides an efficient solution for joining plastic components without requiring additional fastening hardware. When properly integrated into the product design, snap features can simplify assembly and reduce component count.
Bonding
Adhesive bonding can provide discreet, reliable assemblies when product geometry, technical constraints or appearance requirements make mechanical fastening less suitable.
Ultrasonic Welding
Performed directly at our facility, ultrasonic welding provides a fast, clean and repeatable process for joining compatible plastic components. It is particularly well suited to applications requiring consistent joint quality without additional fasteners or adhesives.
Low & Medium Volume Production
Manual Assembly
Well suited to low- and medium-volume production, complex products or applications requiring skilled manual operations.
High Volume
Automated Assembly
For higher production volumes, automation can improve throughput, repeatability and consistency while reducing manual handling.
Finishing & Customization
Finishing, Identification and Product Customization
Beyond assembly, PPI can integrate a range of secondary finishing and decoration operations to add identification, traceability, functionality or visual customization to molded components.
Laser Marking & Identification
Laser marking and identification can be used to add permanent traceability information, product identification or customized markings directly to the component.
Digital Printing
Full-color digital printing enables high-quality visual decoration for products with specific branding, identification or appearance requirements.
Painting & Chrome Plating
For applications requiring specific functional or decorative finishes, PPI works with selected specialist partners for painting and chrome-plating operations.
These services remain integrated into the overall project workflow, allowing PPI to coordinate the complete manufacturing process and maintain consistent quality expectations.
Pad Printing & Screen Printing
Through selected specialist partners, PPI can also provide pad printing and screen printing for functional, regulatory or decorative markings. These technologies can be used to apply logos, text, pictograms, scales and graduations, or technical information. Integrated into the overall manufacturing process, these operations help deliver a consistent finished product without requiring the customer to manage additional suppliers.
From Component to Finished Product
Components, Subassemblies and Products Ready for the Next Step
Depending on your requirements, PPI can deliver molded components ready for integration, technical subassemblies, assembled products or packaged products ready for shipment. By integrating these operations into a single manufacturing workflow, we help reduce handling time, simplify supply flows and maintain consistent quality throughout the project.
Packaging & Logistics Preparation
Packaging Integrated into the Manufacturing Process
PPI can integrate packaging and logistics preparation into the manufacturing process so that parts and assembled products arrive in the format required for downstream operations or distribution. This helps reduce intermediate handling and simplifies customer supply flows.
Our capabilities include:
From Component to Shipment
Simplifying Your Supply Chain
Our assembly and secondary-operation capabilities support a wide range of customer projects. By integrating these operations with injection molding, PPI can reduce processing time, simplify procurement and help maintain quality across the complete manufacturing scope.
Depending on project requirements, we can supply:

A Natural Extension of Our Injection Molding Expertise
One Continuous Manufacturing Process
Assembly and secondary operations complement PPI's core expertise in plastic injection molding. These services are provided as part of the plastic component programs manufactured by PPI, enabling us to maintain control over the product, its quality and its manufacturing performance.
By integrating injection molding, assembly, finishing and packaging, we provide customers with a consistent end-to-end manufacturing solution.

Frequently Asked Questions About Assembly & Secondary Operations
FAQ
What assembly processes does PPI provide?
Depending on product requirements, PPI can integrate screw fastening, snap-fit assembly, bonding and ultrasonic welding into the manufacturing process.
Do you perform ultrasonic welding in-house?
Yes. Ultrasonic welding is performed directly at our facility, giving us greater control over quality, responsiveness and production scheduling.
Do you provide both manual and automated assembly?
Yes. PPI can use manual or automated assembly depending on production volumes, product complexity and project objectives.
What finishing and decoration options are available?
Depending on the project, we can integrate laser marking, digital printing, painting, chrome plating, pad printing, screen printing and labeling. Some specialist finishing operations are performed through selected qualified partners and coordinated by PPI as part of the overall manufacturing project.
Can PPI also handle product packaging?
Yes. Our capabilities include individual bagging, kitting, labeling, cartoning and logistics preparation. Packaging requirements can be integrated directly into the manufacturing flow to reduce intermediate handling and simplify downstream operations.
Does PPI provide assembly as a standalone service?
No. Our assembly and secondary operations are provided as part of plastic injection molding programs manufactured by PPI. This integrated approach enables us to maintain control over product quality and manufacturing performance from the molded component through the final assembly.
