Comprehensive Secondary Operations for Plastic Moulding

At Paul Norman Plastics, we understand that achieving the perfect product often requires more than just the initial moulding process. Secondary operations and post-moulding services can be crucial to meeting budget constraints, enhancing product features, and ensuring the highest quality outcomes that standard tool configurations might not achieve independently.

​

Our extensive range of secondary operations allows us to offer a complete one-stop plastic moulding solution under one roof. This integrated approach streamlines the production process and ensures consistency and efficiency, providing you with a seamless experience from start to finish.

​

Below is a full list of the secondary operations that we can provide:

​

Drilling and Tapping: Precision machining processes for adding holes and threads to moulded parts.

​

Ultrasonic Welding: Creating strong, high-quality joints between plastic parts without adhesives or fasteners.

​

Assembly Services: Combining multiple components into a final product, ensuring perfect fit and function.

​

Pad Printing: Applying detailed, durable graphics and text to plastic parts for branding and labelling.

.

Trimming and Deburring: Removing excess material and ensuring smooth edges for a clean, professional finish.

​

Custom Packaging: Providing tailored packaging solutions to protect and present your products effectively.

​

By offering these secondary operations, we help reduce initial tooling costs, meet budget constraints, and achieve specific product features that standard moulding processes might not deliver. Explore our comprehensive range of post-moulding services to see how we can support your project from start to finish.

Secondary / Assembly Operations Capabilities

Ultrasonic Welding of plastics

Ultrasonic Welding

An industrial technique whereby high-frequency ultrasonic acoustic vibrations are locally applied to workpieces being held together under pressure to create a solid-state weld. 

Ultrasonic welding of plastics
Spot Face plastic moulding to cut cost instead of hot sprue bush

Spot Facing /Machining

Spot facing is the process of cleaning excess material from the part.

​

Machining incorporates various applications additional to moulding such as turning, drilling, and milling.

Remove the sprue from plastic moulding by spot facing
Drill additional holes in plastic part to save mould tool costs

Drilling/Milling

Drilling is the process of adding holes that cannot be carried out during the moulding process.

​

Milling is a way of removing excess material to tighter tolerances that cannot be moulded.

Drilled Holes in plastic sub components for low volume manufacturing
Chrome plate finish silver or gold

Chrome/ Metalizing Plating 

Plating is the process of covering the surface of a part to decorate or protect it, however occasionally it is a necessary process due to functionality and the parts end application.
