3.1 The five questions¶
To understand how AI is used in the engineering of automotive moulded plastic parts today, we looked at the companies that actually shape the field — across the tiers and layers introduced in §1.5 — and asked a different question of each. Five groups came into focus.
3.1.1 The five groups, in Chapter 1's terms¶
Chapter 1 described the industry along two axes: the functional roles (who does which kind of work) and the supply tiers (who sells to whom), with the software and equipment "platform" vendors sitting as a horizontal layer outside the pyramid. The five groups studied here map onto that picture:
- Platform Vendors — the horizontal software layer from §1.5: the companies that build and sell the CAD, CAE and moulding-simulation software everyone else runs. They sit outside the supply pyramid and sell into every tier.
- Engineering Service Providers (ESPs) — §1.5 noted that the functional roles are competencies that "may be bought in." ESPs are the companies you buy them from: paid to do the design and product-engineering work, using the vendors' tools on real parts.
- Automotive OEMs — the carmakers at the top of the pyramid, who specify and style the parts and delegate most moulded-part engineering downward.
- Tier-1 Suppliers — the suppliers that sell systems directly to the OEM, and that typically own the product engineering and often the moulding of the part. This is where the moulding pain concentrates.
- External AI entrants & startups — a second layer outside the pyramid, one level beneath the platform vendors: the model-and-compute layer the industry rents its AI from, and the young companies trying to build moulding AI directly.
A word on how these relate to Chapter 1's axes, since they do not line up one-to-one. OEM and Tier-1 are supply tiers; Platform Vendors and External/AI are horizontal layers outside the pyramid; ESPs are role-for-hire companies that occupy no fixed tier. The five are a study cohort that cuts across the two axes of §1.5 — a way to divide the companies worth studying, not a redrawing of how the industry is structured.
3.1.2 How the groups relate¶
The Platform Vendors sit across the top as a single supplier bar — they sell tools into every other group. The three automotive groups form a chain of upstream/downstream relationships: OEMs specify and delegate, Tier-1s mould and supply, service providers engineer for both. The External & Startups layer is drawn deliberately unconnected — it supplies the AI the others rent, but has not yet landed in the moulding chain itself.
3.1.3 One question per group¶
Reading each group closely, we set out to answer one question apiece. The answers are deliberately held back to the Conclusion, earned only after the evidence in between — the group studies that follow in §3.3 and the cross-cutting Analysis.
| Group | Question |
|---|---|
| Platform Vendors | What capabilities exist? |
| Service Providers | How are they implemented in practice? |
| Automotive OEMs | What problems matter most? |
| Tier-1 Suppliers | Which component workflows are optimised? |
| External & Startups | Who owns the model layer beneath the industry — and who is climbing toward the moulded part? |
The fifth question is different in kind. The External AI entrants and startups are not an automotive tier but the bracket around one, so their question looks beneath the industry rather than inside it — at the model-and-compute layer everyone rents their AI from, and the young companies trying to climb it toward the moulded part.
Before the group studies, the next section explains how to read the evidence — the tags that qualify every claim that follows.
