Description
Large single-cavity molds for interior trim
Interior automotive parts such as door trims and panel parts are large and full of curves. They are usually molded in a single-cavity mold, because one cavity is already large enough to need a big press. Compared with most plastic parts, these molds involve much more work in mold design and mold making.
What a large automotive mold requires
- Large-stroke CNC machines to machine big cavities and cores in one setup; our Hartford gantry CNC has 2060 × 1560 mm travel.
- Double-head EDM to burn deep ribs and details faster on large inserts.
- An engineering team experienced in automotive mold design: lifters for clip undercuts, slides for side features, and cooling for large curved surfaces.
- Hot runners to fill long flow paths with even pressure and good surface.
Mold design for automotive trim
Our engineers design the parting line around the visible surface, plan gate positions so weld lines avoid class-A areas, and choose steels that hold texture and polish. Moldflow is used to predict filling and warpage on large curved parts.
We have built large interior tools for many years. Molds up to 10 tonnes and 1700 × 1500 mm can be produced in our shop.

How we work
How a project like this works
- Tell us what you need – the mold only, molded parts, or both, and your estimated annual volume.
- Send drawings – STEP, IGES, STL, DWG or PDF, or a sample. We sign off moldability in a DFM review.
- Quotation – tooling price, part price and a schedule, with steel, cavities and runner proposed.
- Mold design approval – you approve the 3D mold design before steel is cut.
- T1 samples + FAI report – production or mold shipment starts after your approval.
Shipping molds and parts
- Molds are cleaned, rust-protected, marked and checked against a shipment checklist: cooling circuits, sprue, locating ring, ejection and support pillars.
- Molds ship with drawings, a spare-parts list and the T1 process sheet.
- Parts are packed to your packing instruction and inspected before shipment.
- We ship to customers in Europe, the USA and Asia.
After-sales
Our after-sales team supports mold maintenance and modifications remotely and can supply spare inserts. Contact customerservice@precisemoulds.com.
FAQ
How large a mold can you build?
Up to about 10 tonnes and 1700 × 1500 mm. Our Hartford gantry CNC has 2060 × 1560 × 1070 mm travel for large mold plates.
Why single cavity for interior trim?
Interior trim parts are large, so even one cavity needs a big press. Left- and right-hand parts are sometimes combined in one mold when size allows.
How do you protect the class-A surface?
The parting line, gates and ejectors are placed on hidden areas, and the cavity is polished or textured to the vehicle standard and protected during assembly.
