The number of surfers using saunas to recover from intense physical exercise in low-temperature waters is growing. Here's why the two match.

What LS Mtron calls the first-ever application of AI technology to the injection molding process synthesizes AI into the process optimization of the injection molding machine, reducing production downtime. CSI4.0 is composed of AI Weight Control, which detects changes in the weight of the molded product through a weight meter linked to the injection machine, and the AI Molding Assistant, which reduces the time it takes to stabilize the initial process by adjusting process conditions through learning and emulating skilled molding experts, said the company.

All in all, the H4 Series promises to create maximum power output for effort, minimal drag for optimum speed, and deliver a feeling of predictability and effortless control at every riding moment.

The base is skewed forwards, offsetting the high rake angle in the tip to minimize drag, maximize speed and maintain the smooth turning nature of a more traditional shaped template.

FCS states that the two radically different side and center fin templates create a set with ultimate speed and drive that doesn't compromise control or maneuverability.

With a focus on speed, newly developed foils on the side and center fins significantly lower drag and introduce flex in the upper half of the fin precisely where it's needed.

The center fin's tapering elliptical outline offers progressive stalling behavior at the most critical moments, meaning the fin will release precisely when you need it.

The injection molding machines incorporate Industry 4.0 features to improve productivity, added LS Mtron. By integrating smart molding functionality acceleration performance is improved, plasticity is increased through adaptable screws with increased RPM, and clamp force monitoring is enabled through a tie-bar sensor. Automated clamping force calibration and an automatic zero adjustment mode function for spring molds are also supported. In addition, the One-E line utilizes a dual center press die structure to minimize mold deformation while boosting. As a result, mold face pressure distribution is improved by 33% on the fixed plate and the life of the mold is extended, according to LS Mtron.

The surfboard fin company says that "when you initiate a turn, H4 will supply speed when you need it, and then release it at the ideal transition point."

It all started with the H2 Elliptic fin, which married a nautical-inspired template, a unique side fin foil, and extreme cant angles.

The Qiantang River in China is home to the world's largest tidal bore. It is also the spiritual crib of the country's first wave riders.

"The project has always been about pushing boundaries and adapting functional design theory to hardware with a goal to enhance the surfing experience through a better performing fin," FCS explains.

So, FCS teamed up with a Swiss company to use precision injection molding and fused unidirectional carbon to produce a fin that optimizes all variables - materials, geometry, and flexibility.

Furthermore, the hatchet-like shape of the tip creates stability and a feeling of control and certainty under extreme loads.

These foils also create a very high stall limit providing a feeling of predictability through the most acute turns and in critical wave moments.

The side fin's upper section serves to produce instantaneous acceleration from take-off to bottom turn via an efficient rebound effect.

The CSI4.0 — Connected and Smart Injection — function is a singular feature of One-E injection molding machines. It provides customers with flexibility and ease of implementation of digitally enhanced operations, including data collection, data analysis, and big data processing technology, said the company. An artificial intelligence (AI) stage applies the data from this process to help customers achieve precisely molded parts with excellent surface finishes.

"We applied our learnings to the H3 Nexus and took it one step further by combining an elliptical template with a three-dimensional flex pattern that could harness and release energy in the form of projection and speed."

LS Mtron Injection Molding Machines USA has expanded its One-E line of electric injection molding machines with 55-, 90-, 145-, and 440-ton machines. The high-speed line complements the complete range of standard all-electric machines, which range from 35 to 950 tons, said company President Peter Gardner.
