Penetraor P620 T300 Carbon Fins
Our Famous NAKED CARBON T300FINS now come in a compact version to suit smaller framed divers. The P 620 range features a 62cm working length blade in SOFT flex only. The blades are 19cm wide. The shorter blade promotes a more efficient fining style in divers with shorter leg length reducing excessive knee bend that can be caused by longer blades.
Penetrator blades are manufactured using a proprietary Capillary Closed Moulding System (CCMS). This system is a culmination of 25 years’ composites manufacturing experience applied to fin blade development over the past 8 years by Penetrator Fins founder Larry Gray.
The process eliminates the requirement for secondary processing materials used by other manufacturers producing an outstanding surface finish on both sides of the blade and reduces waste. These 2 outcomes alone produce a blade with a smoother flex curve and reduces the environmental footprint of the manufacturing process.
All metal production tooling has been produced in-house utilising Penetrator Fins CAD design and CNC manufacturing capabilities. Mould temperatures are digitally controlled through the process to ensure the specially formulated resin system reaches its ultimate mechanical properties. Only certified carbon and glass fibres issued with a certificate of conformity (usually reserved for aerospace applications) are used. Full process control over these parameters ensures engineering performance measures are consistently achieved.
Carbon Fiber blades receive a protective layer of Kevlar 49 multi-axial reinforcement in the tip of the blade to prevent chips and cracking. This system is unique to Penetrator blades. Kevlar is an extremely resilient and flexible material providing added impact resistance while allowing full flexibility of the blade tip.
Once moulding is complete fin blade profiles are CNC machined to an accuracy of .01mm. Penetrator Fin’s proprietary rubber water rail is then added with cyanoacrylate adhesive in purposed built pneumatic clamping jigs.
