Heathcote Industrial Plastics have been manufacturing composite leaf springs in the UK since 1979, and are world leaders in the manufacture and supply of composite leaf springs for vibratory conveyors and feeders, offering unparalleled levels of service and support.
We manufacture all of our own composite materials in our factory here in the heart of Staffordshire. Combining the finest raw materials into our unique composite spring panels, which are engineered for performance and reliability, and all manufactured under our ISO9001 accredited quality system.
-
Four different materials available depending on your requirements.
-
Wide range of stock thicknesses from 0.8 to 8mm available for dispatch in as little as two working days.
-
Standard lead time is just 10 working days.
-
Ship globally, currently to over 30 different countries.
Our HiFlex Glass springs combine high performance unidirectional glass fibres with Heathcotes dark green epoxy resin. The quantities of glass and resin, and the fibres used are optimised to give the maximum performance in flexural strength and stiffness.
This material was engineered to replace the old 3M ScotchPly material, but with an increase in the flexural modulus from 28Gpa to 36Gpa.
For more demanding, high performance machines, Heathcote Industrial Plastics have designed HiCaFlex. These springs are engineered with aerospace grade unidirectional carbon fibres and Heathcotes dark green epoxy resin. to provide the highest levels of flexural stiffness.
HiFlex High Temperature Glass:
Heathcote Industrial Plastics high temperature glass springs uses an advanced epoxy resin system which is engineered to perform at higher temperatures. This allows the springs to operate at temperatures 60% higher than our standard HiFlex material.
Hybrid spring material is the latest innovative composite material from Heathcote Industrial Plastics. Using multi-layer technology to combine both glass and carbon fibres to give the benifits of both materials.
The added carbon increases the flexural modulus of the material far beyond what can be achieved by glass fibres alone, but the glass in the mixture reduces the overall cost of the product, giving the performance increases you see from carbon fibre without the price increase.
It is often necessary to bank the springs together in “spring packs” in order to get the required performance. To ensure springs are well clamped and to stop the springs rubbing together Heathcote Industrial Plastics manufacture high quality spring spacers from thin SRBF sheet.
Heathcote Industrial Plastics also manufacture shaped and curved springs and springs of non-uniform thickness. These are available in Hiflex Glass, HiCaFlex Carbon, HiFlex High Temperature and Heathcotes Hybrid materials and have applications in a wide range applications from Automotive to Electrical.
Jig checks can be applied to ensure the tightest of tolerances.
Springs are printed with Part number and LOT number, but custom printing is available
Spring sides can be painted to allow easy identification of different thicknesses.
Custom coatings can also be applied to our springs, such as PTFE or Teflon.
Not sure which material is right for you, how many springs you will need or what thickness they need to be?
In the Downloads section of our website we have our spring manual, a complete guide to how to use our springs on your vibratory feeder or conveyor.
We also have a number of Excel Calculators to help you with the calculations.
