Glass-Filled Interior Automotive Molded Part

Glass-filled nylon instead of metal

Glass-filled nylon is replacing metal in many interior automotive parts. This component is molded in 30% glass-filled PA66, which is strong, stiff and stable at cabin temperatures, yet much lighter than a die-cast or stamped part. Lower weight helps fuel economy, and in electric vehicles it adds range. Molding also allows shapes, clips and ribs that would be expensive to machine.

Tooling for glass-filled PA66

Glass fibre is abrasive and PA66 runs hot, so the mold needs the right steel and the right design:

• Two cavities in AISI H13, a hot-work steel that resists wear from glass fibres.
• HASCO standard base and components.
• Gate size and position chosen to control fibre orientation, which affects both strength and warpage.
• Vents and cooling balanced so both cavities produce the same dimensions.

Built by the team that molds it

We have made molds for interior automotive accessories for decades. Because our own presses run the T1 trial, we see the real behaviour of the glass-filled resin before the mold leaves our shop, and we correct shrinkage or warpage in the steel, not in your plant.

For customers looking at sustainability targets, we can mold the same tool with recycled or partly recycled PA66 grades approved by your engineering team.

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.
