RTM, Resin Transfer Molding is a manufacturing process where a fiberglass continuous mat is placed in a closed female / male tool. Under pressure the mold cavity is filled with liquid resin. An injection machine is used to fill the mold.
ACS’s RTM process utilizes large presses and heavy tooling to ensure high quality parts. ACS’s proprietary molds are computer temperature controlled for repeatability and part consistency. Average tool weight is 4-5000lbs
ACS parts are smooth on both sides, and are prepped and primed. The rest is in the formulation and durability of the part. Time will tell you… It is all about the process and materials used…
ACS’s RTM process utilizes large presses and heavy tooling to ensure quality parts. ACS’s proprietary molds are computer temperature controlled for repeatability and part consistency. Average tool weight is 4-5000 lbs. Another secret, unlike typical hand laminated parts, which are made in low cost lightweight composite tools, which tend to distort and bend over time.
•Parts are same thickness throughout, insure proper stack height and an excellent fit on the vehicle
•Smooth finish on both sides of panel
•Similar mechanical properties to SMC (Sheet Molding Compound)
•Consistent glass/resin ratio content
•Fully cured in mold
•High filler rate for great heat distortion resistance
•Tested for automotive glass A finish
•No air pocket or dry spots
•Tested for durability and show finish, will not distort under extreme heat
•Environmentally friendly, low VOC emissions as part is cured in a closed mold
Many will say they can purchase fiberglass hoods for half the price. Just like cars, performance will vary with each model. ACS’s RTM manufacturing process has been tested and validated by both GM and Ford and can be found on some of America’s most recognizable muscle and supercars like Camaro’s and the centennial Ford GT. Unlike most aftermarket composite panels, ACS’s process has been tested to withstand High Heat and 7 yr. durability standards; a requirement for class A automotive panels.

ACS uses a Motoman robotic water jet to trim every inner hood panel. A 50 000 psi ultra thin water jet cuts trough every panel with great precision. This warrants a perfect vehicle fit. The inner panel mounting holes and latch location are predetermined by the robot. Cut outs are also performed on the inner panel to reduce weight and insure the hood’s absorption of impact in the event of a frontal collision.
A model specific holding fixture is in house designed. Once the panels are trimmed and dried they proceed to the bonding department where another Motoman robot applies the required adhesive.
A few advantages of water jet cutting are
– Consistency and repeatability
– Precision
– Ability to cut true squares
– Smooth edge
– No part / tool contact
– Dust free environment
