Automotive Parts Trays: Fit, Handling and Tooling Review

AUTOMOTIVE · PROJECT DEVELOPMENT

Parts that stay located.
Room to lift them out.

Developing four automotive tray designs meant balancing component fit, removal space and stacking. We worked from the customer’s layouts, marked the sample observations and carried those details into local tooling revisions.

APPLICATION

Automotive component handling

DEVELOPMENT SCOPE

Four tray designs, tooling and sample review

DESIGN PRIORITIES

Location · removal · stacking

The tray had to work with the equipment.

The customer needed parts to remain located without becoming difficult to remove. The brief also called for stacking and features that the automated equipment could recognise.

Those requirements could not be resolved independently. Tightening a pocket could restrict removal; changing a corner could affect stacking. Our design work considered the component, its handling path and the thermoforming geometry together.

Each layout has a different component arrangement. The original drawings retain their model-identification marks; the descriptions below explain the features in English.

Layout A — compact component pockets

The pockets and notch positions define this tray layout.

Layout B — elongated component pockets

The long pockets follow the component envelope and its support requirements.

Layout C — an alternative pocket arrangement

Make the handling features manufacturable.

We developed the supplied layouts into thermoforming designs. Model-identification notches, moulded direction arrows and trimming references had to remain consistent with the equipment brief.

The handle needed a second kind of review: how it would be gripped in use, and how the formed tray would release from its tool. The design included sliding tooling for demoulding. This is where the handling requirement met the practical work of making the part.

Stay with the detail, not just the drawing.

With components placed in the samples, the team recorded where they moved and which local surfaces could be adjusted. The notes describe approximately 0.5–2 mm of play and pieces of 1 mm sheet used as gap-checking aids—not a final tolerance specification.

We linked the marked photographs to selected areas on the tool drawings. That made the discussion specific: where was the unwanted movement, what could be changed locally, and what space still had to remain for removal?

The aim was to address the fit without making unnecessary changes elsewhere in the tooling.

From an observation to a tooling decision.

The photographs and corresponding drawings below show how the sample review was carried into local revisions. Two groups of full-length workshop videos keep the original and follow-up checks available for a closer look.

In the annotated images, the arrows and highlighted surfaces identify areas selected for review. Any machining dimensions belong to those local proposals; they are not finished-part tolerances.

Does a part move—or catch—inside your tray?

A marked photo and a short handling video can make the issue easier to discuss than a drawing alone.

Discuss the Fit of Your Tray

Keep stacking in view when changing a corner.

On one tray, eight corners were noticeably thin and could be depressed by hand. The review identified stepped geometry with very little draft in those areas.

The proposed revision replaced abrupt details with bevelled transitions to ease local stretching. But forming was only part of the decision: the tray still needed the geometry required for stacking.

A separate deep, narrow region also needed attention. The proposed sloping transition addressed the local geometry while preserving the component space. The available record does not quantify the resulting wall thickness.

What this project shows.

The work did not stop at translating a layout into a tool. We followed the sample observations into particular contact surfaces and corner details, then kept the follow-up checks connected to those changes.

That is the practical value of working through a project together: a fit concern becomes a location to review, a proposed adjustment and a question for the next sample—not just a general request to “make it better”.

Project stage & evidence

This case documents design, aluminium tooling and sample-review work. Final customer acceptance and production-line validation are not reported here. Manual checks do not establish robot cycle performance, service life or a quantified improvement in wall thickness.

All 17 project images and four full-length videos are retained on this page. Open the labelled sections to explore the complete record. Identifying labels are masked and video audio is removed for confidentiality.

Show us how your parts need to be handled.

Send the component layout, explain how the parts are loaded and removed, and point out any movement or catching. Include stacking requirements if they affect the design.

We can discuss the locating features and forming constraints with your team, then identify what the next sample needs to demonstrate. A drawing, marked photo or short handling video is a useful starting point.
