Springs
Composite SpringsComposiflex, Inc. is a manufacturer of high performance composite springs. For the past several years Composiflex has supplied a variety of E-glass/epoxy, carbon/epoxy and high temperature glass/epoxy springs to numerous vibrator and conveyor manufacturers. We supply cross-ply, spring orientation and unidirectional constructions as required. Many of Composiflex's customers use these constructions as direct replacements for 3M springs. |

Many of these manufacturers have performed demanding fatigue tests and small quantity in-service evaluations in order to guarantee superior quality. In all of these tests Composiflex springs have performed to the highest standards. In many cases our customers have praised the superior performance of our springs over other suppliers. Almost all of our customers have ordered on several occasions, acknowledging their trust in the quality and fatigue performance of our springs. Composiflex has never had a premature failure or an unhappy customer. In particular, the carbon/epoxy springs have performed extremely well in demanding high stress and start/stop situations. |
One customer has tested the carbon springs under extreme conditions only to have the attachment bolts fail time and time again without measurable loss of spring performance. Our success is in part a result of a modern high performance epoxy resin. This material is a toughened, high elongation resin demonstrating excellent fatigue properties. Although it is a 250 deg. Farenheit resin system, it is capable of temperatures as high as 300 degrees for short periods. This resin is impregnated in E-glass fibers and carbon fibers to form a unidirectional pre-preg that can be conveniently layed up into a variety of constructions.

| In response to the success of our springs and our desire to serve our customers, Composiflex has undertaken a significant test program to quantify the properties and performance of our spring material. To date only the low temperature E-glass springs have been formally tested by an Independant Laboratory. 4-point Bending test per ASTM D-790 for flexural strength and modulus and inter-laminar shear properties per ASTM D-2344 are recorded in the table below. |

Composiflex intends to continue testing the properties of its springs, including high temperature springs, carbon/epoxy and hybrid (carbon/glass)/epoxy springs. The data will be published in a brochure and made available to spring customers to assist in the design of new equipment. We now offer additional products for the vibratory conveyor industry. Conveyor pans can be made that are lightweight, metal free, and with food grade liners. These liners are tough and durable to withstand impacts and constant abrasion from conveying materials. We use a glass epoxy, similar to our springs, that is then covered with UHMW matting that is actually part of the finished part so it can't flake off, or peel off during use or installation. We can custom design full pans, pan sections, wear liners, dewatering sections, screening sections, discharge chutes or whatever else you desire. We can make various size widths, depths, and lengths up to 12 feet.
