Tool free enclosure manufacturing enables the production of fully customised enclosures without moulds, using CNC machining, cutting, heat bending and assembly techniques applied to flat plastic sheets.

This approach removes expensive tooling costs and significantly reduces lead times, making it ideal for prototyping, proof of concept work and low to medium volume production.

Key benefits

  • No tooling costs or upfront investment
  • Faster turnaround times (typically 3-4 weeks)
  • Easy design changes and iteration
  • Suitable for prototyping and low to medium production volumes

When should you use a tool free enclosure?

Tool free enclosures are best suited to projects where flexibility, speed and cost control are priorities.

They are typically the right choice when:

  • An off-the-shelf enclosure is not suitable
  • You want to avoid high tooling costs
  • You need a fast turnaround
  • You are developing a prototype or proof of concept
  • Production volumes are low to medium
  • Design changes are likely between iterations

For higher volume production, injection moulding may become more cost effective. However, for many industrial and electronic applications, tool free manufacturing offers a more practical and efficient solution.

How tool free enclosure manufacturing works

Tool free enclosures are produced using a structured fabrication and assembly process, allowing for precision, repeatability and flexibility.

Step 1 – Consultation

Discuss your design requirements with our team, including material selection, sizing and assembly needs.

Depending on complexity, CAD files may be required, but we can also work from simple sketches or create enclosures around assembled components such as PCBs.

Step 2 – Final Design

Before manufacturing begins, the design is finalised between Evatron and the customer.

For more complex projects, a sample may be provided for approval. Material specifications such as temperature resistance, flame retardancy and colour are also confirmed at this stage.

Step 3 – Production

Once approved, manufacturing begins.

Enclosure components are precision cut from flat plastic sheets using CNC routing, including apertures, vents and fixing points. Panels may also be prepared for bending using scoring techniques, allowing accurate forming during the next stage.

Artwork such as logos and labels can also be applied during production.

Step 4 – Assembly

All components are assembled by folding and bonding each segment to create the final enclosure structure.

This includes solvent bonding techniques to create strong, seamless joints, along with the installation of inserts or fixings where required.

Final finishing processes such as printing or surface treatments can also be applied. Your designs are securely stored for repeat orders, and thanks to the tool free approach, future modifications can be made quickly and easily.

Applications and use cases

Tool free custom enclosures are used across a wide range of industrial and commercial environments where standard enclosures are not suitable.

Typical end uses include:

  • Industrial control panels and systems
  • Electronic and PCB housings
  • AV and display installations
  • External equipment housings requiring sealing (e.g. IP-rated use)
  • Custom machinery or specialist equipment

Case Study

BMS Interface Housing

Challenge

A building automation specialist required a custom housing for a high-performance interface device used to monitor and control large-scale HVAC systems. As a plug-in replacement for a legacy product, the enclosure needed to accommodate modern hardware including a touch screen and web-browser interface while maintaining a form factor compatible with existing infrastructure and mounting points.

Solution

Using tool free manufacturing, a custom plastic enclosure was developed to house a specific PCB and touch-screen components without the limitations of a standard “off-the-shelf” enclosure. High-precision CNC machining ensured perfect apertures for the display and connectivity ports, while the internal architecture was optimised for rapid assembly as a direct replacement unit.

Outcome

The tool free approach allowed the client to bring their updated interface to market significantly faster, bypassing the high costs and long lead times associated with traditional injection moulding. The result is a high-spec, professional finish that reflects the advanced technology inside.

Furthermore, the process provides long-term design flexibility. As hardware specifications evolve, the enclosure design can be refined without the cost or delay of new tooling ensuring the client can consistently meet tight project deadlines and stay ahead of industry standards.

Tool Free Material

Materials and finishes

A range of materials can be used depending on the application and performance requirements. Common options include:

  • ABS
  • HIPS
  • Polycarbonate (including flame-retardant grades such as UL94-V0)

Enclosures can also be customised with:

  • CNC-cut apertures and features
  • Inserts and fixing points
  • Printed branding and labels
  • Surface finishing and coatings
  • Environmental sealing where required

FAQs

What is tool free enclosure manufacturing?

It is a method of producing custom enclosures without moulds or tooling, using fabrication processes such as CNC machining, cutting, bending and bonding.

Is tool free manufacturing suitable for production runs?

Yes, it is ideal for low to medium volume production where flexibility and reduced upfront cost are more important than mass production efficiency.

How does tool free compare to injection moulding?

Tool free manufacturing eliminates tooling costs and reduces lead times, making it ideal for smaller runs and custom designs. Injection moulding is typically better suited to very high-volume production.

How do I get started with a tool free enclosure?

You can start with anything from a full CAD design to a simple sketch or even a physical component.

Evatron will work with you to define the requirements, refine the design and recommend suitable materials and manufacturing approaches.

Can Evatron manage the full process?

Yes, Evatron can manage the entire process from initial concept through to design, production, assembly and finishing.

This ensures consistency, reduces risk and provides a single point of contact throughout the project.
