TC760X
As part of its ongoing commitment to supporting the environment, Trelleborg's latest tooling board the TC760X provides a dust free machining experience reducing airborne particles and environmental impact, and improving production efficiency.
TC760X is a medium temperature, low density syntactic epoxy tooling board designed to act as a more durable/higher temperature master molding base or facilitate direct-to-part tooling.
TC760X is a superior quality tooling board, offering crack resistance and dust free machining.
Dust free machining
Excess product comes off in large flakes rather than dust, significantly reducing residue on machinery
A class surface finish
Can be machined to a high quality surface finish that requires virtually no finishing
Excellent toughness and durability
Maintains its shape at elevated temperatures with minimal cracking and edge chipping
Suitable for operation temperature use up to 135°C*
Easy to seal
Requires up to just 4 coats
Key Applications
Master models, direct to part tooling
Lay-up tools for low and medium temperature epoxy prepregs
Product sizes
TC760X is available in a standard board size of 24” x 60” at the following thickness: 2”, 3”, 4” and 6”
Cutting
TC760X can be sawn using carbide or diamond coated saw blades or cutting wheels
Bonding
Large patterns can be constructed from boards using the appropriately selected epoxy adhesive system. Trelleborg adhesive system 551A/B is recommended. The adhesive system must offer adequate pot life and be capable of meeting the mechanical and thermal properties of the tooling board.
