Expert Extrusion Design Services
Nenplas have a dedicated team of product development engineers who will help you with all aspects of the plastic extrusion design process to ensure your extrusion requirements are fully achieved.
Our Plastic Extrusion Design Process
Once a project has been approved and we’re ready to create a plastic extrusion for your bespoke product, our dedicated NPD department takes complete ownership of the process. We manage each step from plastic extrusion design to manufacturing.
We take the time to discuss your exact vision and needs to make sure we fully understand the functional requirements involved and the end-use conditions for the product. During the planning process, we use 2D, 3D and CAD prototyping, working closely with you so that your feedback can shape the direction of the work.
We don’t lock customers into the first draft. We work with you until you are satisfied with and have signed off a master sample, giving you confidence that the final extrusion will meet your exact specifications.
Collaborative Design Engineering
2D, 3D and CAD Extrusion Prototyping for Design Validation
At our Ashbourne premises, we have a fully-staffed product development department with 2D and 3D CAD specialists and a rapid prototyping facility to bring your custom plastic extrusion designs to fruition. Having on-site 2D, 3D and CAD extrusion prototyping capability means our specialist design and engineering teams will work cohesively with you to deliver fully integrated solutions for your plastic extrusion profiles.
Plastic extrusion modeling helps us verify the final product has the correct dimensions and visual features and allows us to communicate clearly with you to support this. Concepts can be amended at each stage based on customer feedback.

Tooling Support as Part of the Design Process
Plastic Extrusion Tooling Design
Nenplas offers a plastic extrusion tooling design service to allow extrusion profile concepts to be built with manufacturability in mind from the outset. This approach helps integrate tooling considerations early on in the design process, shortening lead times and reducing the need for revisions while making the transition from design validation to production smoother.
Nenplas has made significant investments to our Ashbourne tool room to ensure it is a world class facility that allows us to produce exceptional PVC extrusion profiles. Our bespoke tooling is designed and manufactured in a state of the art tooling room by experienced in-house teams using modern equipment including wire erosion technology. Our toolmakers closely collaborate with our design engineers to make sure extrusion profiles are optimised before tooling is finalised.

Plastic Extrusion Design FAQs
Plastic extrusion design is the process of engineering and planning your custom plastic profile and involves planning the dimensions, shape and raw materials as well as the cutting, cooling and post-processing steps.
This stage is integral to the final result as it dictates its functionality in end-use conditions as well as structural integrity and manufacturing efficiency.
Offering in-house plastic component design shortens our lead times as it removes the need to rely on third-parties and it also allows for a smoother feedback loop between us and the customer and the opportunity to adjust the approach as needed at each stage.
Nenplas has vast experience in planning and engineering of custom plastic extrusions, having supplied a vast range of markets and applications both nationally and internationally for decades.
What’s more, we always prioritise communication with the customer, not only to be able to apply your requirements in the best way possible but also to use your feedback to guide the process. We use 2D, 3D and CAD prototyping for easy visualisation and validation of the model’s properties.
We’ve made significant investments in our facilities to make sure we’re able to provide you with the highest quality plastic extrusion profiles while keeping lead times short and your project as cost effective as possible.
2D, 3D or CAD prototyping supports easy visualisation and validation of properties at concept-level. It helps us detect any flaws early on preventing expensive large-scale production failures, reducing material waste and helping us make sure the final product meets your exact requirements.
At Nenplas, the plastic extrusion design process is managed by our expert product development department, including 2D, 3D and CAD specialists. They work cohesively with customers to deliver fully integrated solutions for your plastic extrusion profiles that meet project requirements and are fully fit for purpose.
