In-House & River Testing

Monitoring our molding process prior to the finished product has allowed us to exceed our supplier’s published polymer strengths by 30%.

How are we able to determine this you ask?


We strictly monitor all of our high tech rotational molding ovens, molds, processes, and materials. We use a high temperature profiling system that allows us to follow an intense series of combinations and experimentation. Our engineered polymer design requires specific cooking and cooling methods to ensure the best mechanical strengths. Great efforts go into maintaining consistent, repeatable, and reliable plastics. Monitoring our oven and cooling cycles allow us to exceed our supplier’s polymer strengths by 30% as determined through the use of destructive mechanical in-house and field analyses.

Dart impact testing allows us to evaluate the impact strengths and toughness of our plastic. We use the dart impact to determine the amount of impact that may be applied to our finished product when placed on the river with our customers. In testing, we consider the effects of various environmental factors, including temperature. Our favorite testing method uses destructive mechanical in-house testing. In-house product testing subjects plastic to -40 Celsius. This is all based on the time and temperature at which we cook and cool our plastic.

Dart impact also allows us to study our plastic for abnormalities to better provide you with the best plastic in the market. Consequently, we have a library of archived data that will help us provide you with the best customer service if there are ever materials not performing to our standards.

The Pull Bar is a test performed to simulate what a typical bar, the hull plastic, and the insert may be subjected to during a real life rescue. This is a threefold analysis that simulates a swift water rescue. A force is applied downward to the boat, while another force is applied upward to the grab handle. The plastic and the grab handle are held together by a strong force, specifically, a specialized and custom insert. We measure the amount of net force being applied to the boat. The results have allowed us to make the best choices regarding parts we use and the boat creation processes. Ultimately, the plastic is cured to its optimum mechanical strength with an added superior grab handle backed by custom made inserts and we have a product that withstands forces stronger than any boat on the market, more importantly, a reliable boat during a swiftwater rescue.

Laboratory results and Field experiments. This drop testing goes hand in hand with nature’s unpredictable force. This is a mechanical energy that can not be controlled or can not account for all variables. The unforeseen and variable outcomes can influence whether your boat can withstand impact forces taking sudden impacts at places like “go left and die”. These results, although hard to measure impact forces, can help us gauge environmental measures.

After the in-house testing has been completed and we feel confident with our results, liquidlogic’s employees are given the opportunity to take the product out and test it in our very own backyard. The Environmental sample design experiment is measured on ultra low volume. The data collected is then compared to our control experiment, our in-house mechanical impact analysis.

The data collected is based on the amount of time spent on the water, cfs, and the potential energy of impact applied. Our data collected is based on subjecting our material to the most extreme and varied cases. Even if our results are acceptable in-house but the experimental results are poor, we will re-design our experiments. We allow these trials to continue from several weeks and up to two years before determining the plastic is certifiable.

Once we have collected all of the information on our post-river trials and are confident in a well-developed sampling design, a sound, science-based decision is founded on the data collected and is then ready to be certified and released to you.
