NTPT offers Automated Tape Laying (ATL) equipment for the efficient incorporation of prepregs into molded parts, allowing users to save on both materials and labour costs, whilst retaining full design freedom for the manufacture of advanced composite parts.
Offered with full design, kitting, and stock management software, NTPT says its ATL solutions are widely used on a daily basis.
NTPT estimates that a single ATL can handle the work of eight to ten composite laminators, with full traceability, and no possibility of prepreg backers being left within the laminate. High quality, efficient part production, reduced part contamination, and reduced exposure of uncured polymeric materials to the workforce are some of the many advantages NTPT’s ATL equipment brings. A new generation of ATL machine, marketed at an ‘everyday’ price is affordable to smaller molding companies looking to reduce labour costs, reduce material wastage, and increase part quality.
The plotting surface is defined as the area on which tapes can be laid in any direction and cut at any angle. surface footprints are offered according to the following ranges:
S series: W= M series: W= 3m to 4m x L = 3 to 6m (9 to 24sqm)
L series: W= 4 to 4.5m x L=6 to 14m (24 to 63sqm)
Custom: by arrangement
The top of the table is located at 800mm.
Laying down tapes
NTPT ATL lays down prepreg tapes, the fibre areal weight can range from 30gsm to 300gsm.
Drawing and cutting curves
NTPT’s ATL machines are supplied with an integral cutting gantry. Curves can be drawn or cut in the entire working surface. by the cutting plotting gantry.
An onboard camera enables a remote and real time control of the tape laying operation. A remote operator is able to view the most critical aspects of the tape laying operation live from a remote computer.
Production rates of up to 300lm per hour are achievable as standard rates, depending on part geometry and tape length. Productivity can be further improved depending on nesting – with a potential to double this rate.
NTPT says its ATL equipment was used to manufacture the preforms for its award winning Thin ply quartz prepreg.
