TPU 95A Tooling Covers for Aerospace

Aerospace manufacturing requires precision at every stage of production. From the components that eventually enter an aircraft to the tools and equipment used to manufacture them, every part of the process needs to be carefully considered.

This is one of the reasons additive manufacturing has become such a valuable technology for aerospace and advanced manufacturing. 3D printing allows engineers to create specialized tooling, protective components, fixtures, and covers without relying on long lead times or expensive conventional tooling.

For applications that require flexibility and protection, TPU 95A is an especially useful material.

What Is TPU 95A?

TPU, or thermoplastic polyurethane, is a flexible engineering material known for its resilience, impact resistance, and ability to deform and return toward its original shape. The 95A designation refers to its Shore hardness, placing it in a semi-rigid range that can provide a useful balance between flexibility and durability.

Unlike rigid plastics, TPU 95A can absorb impacts and provide a softer interface between a tool and the component it is designed to protect. These characteristics make it well suited for protective coverings, flexible tooling components, grips, gaskets, and other manufacturing applications.

TPU 95A Tooling Covers

In an aerospace manufacturing environment, tooling and production equipment are often exposed to repeated handling, contact, vibration, and impact. A tooling cover can help protect the equipment while also protecting surrounding parts and surfaces.

Traditional methods of producing custom flexible components can involve specialized tooling, additional fabrication steps, or minimum order quantities that do not make sense for a custom or low-volume application.

Additive manufacturing provides another option.

With 3D printing, a tooling cover can be designed around the exact dimensions of the equipment. The CAD model can incorporate mounting features, cutouts, retaining details, and other geometry needed for the application. The result is a purpose-built component rather than a generic cover adapted to the job.

TPU 95A is particularly useful where the cover needs to flex during installation or removal while still providing a durable protective layer.

Aerospace Manufacturing Applications

Aerospace manufacturing presents an especially strong case for customized tooling because many production environments use specialized fixtures and equipment that are not available as standard commercial products.

A 3D printed TPU tooling cover can be designed for a specific fixture, production station, or component interface. Its flexibility can help accommodate irregular shapes while reducing the likelihood of scratching or damaging sensitive surfaces.

TPU materials are also used in applications such as protective coverings, shock absorption, non-marring work holding, grips, and flexible tooling.

For aerospace manufacturers, this opens the door to practical improvements throughout the production process.

A protective cover does not need to be a complicated component to create meaningful value. Sometimes the simplest custom part can reduce damage, improve handling, simplify setup, or make a workstation more efficient.

Why Use Additive Manufacturing for Tooling?

The biggest advantage is flexibility.

A traditional tooling process can require significant planning before a part is ever produced. With additive manufacturing, engineers can make changes directly to the digital model and produce a revised component without starting the tooling process from scratch.

This is particularly useful during product development, equipment changes, process optimization, and low-volume manufacturing. It also supports rapid iteration when a tooling cover needs a slightly different fit, opening, thickness, or mounting feature.
