A handful of good automotive mold manufacturing pictures I found:

COMPOSITE REAR SEAT CUSHION FRAME
•OEM Make & Model: Hyundai Kia Automotive Group 2012MY Kia® K9® sedan
•Tier Supplier/Processor: Dymos, Inc.
•Material Supplier / Toolmaker: Honam Petrochemical Corp. / not provided
•Material / Procedure: PP / Vacuum bag, autoclave cure
•Description: Replacing a spot-welded steel structure with a 1-shot, injection-molded high-strength (lengthy-glass/high-crystalline) PP composite allowed for development of a lightweight, low-price rear seat cushion frame for a rear-wheel-drive sedan. The application reduced weight 25% and charges 10% whilst improving the manufacturing method and has generated 1 Korean patent and 2 added patents overseas.
Carbon string is employed as a conducting bridge in the preparation of specimens for observation in the scanning electron microscope (SEM). It is also representative of the preforms utilised in the manufacture of some carbon fibre based composite elements. Fibres can be woven into suitable shapes utilizing conventional weaving technology. The preforms can then be injected with the resin matrix by processes such as resin transfer moulding (RTM) or resin film infusion (RFI).
Carbon fibres are developed by oxidising polyacrylonitrile in air at 230 deg C whilst applying tension, and then carbonising the item in nitrogen at 1000 deg C
Carbon string is woven from the fibres that result from the drawing of carbonised PAN
Carbon fibre composites are utilised as a structural material in the aerospace and automotive industries, as properly as in specific high-performance sporting gear. They present exceptional stiffness and can be structurally optimised for distinct load-bearing applications.
