Product Testing

U.V Weather Testing

If your product is designed for external use, you may have some concerns about the possibility of plastic degradation from constant U.V exposure. As part of our commitment to produce and supply the best quality injection moulded parts available, we are constantly testing both our products and the materials we use for their resilience against U.V Light damage.

The Process

Random components are selected after moulding and tested using our onsite Q.U.V Weathering Tester. The components are placed in the machine and are subjected to U.V levels at a temperature of 60ºC. The test conditions represent a clear day, where no pollution is present. The system we use also ensures constant U.V exposure throughout the test, more intense than in natural conditions where U.V is broken up by differing weather conditions and nighttime.

The duration of testing is based on the average sunshine hours of England & Wales (1671.4 Hours P.A). Our system allows us to speed up the process, so that you do not have to carry out lengthy product development and field tests; the duration conversions are shown below:

Duration In Weather tester: Equivalent Real Life Duration:
6 Days (139.28 Hours) 1 Year
12 Days (278.56 Hours) 2 Years
18 Days (417.84 Hours) 3 Years
29 Days (696.40 Hours) 5 Years

Our experience from previous testing shows that including 3% U.V additive at the moulding stage, provides sufficient U.V protection for a component throughout its lifetime. Adding more additive at the moulding stage does not yield any further benefits in terms of U.V protection.

Pull Testing

Will the final product be strong enough?

If the component is expected to withstand a certain amount of weight when in use, we are capable of simulating that and fine tuning a product to be strong enough for your requirements. Originally used to test and prove the strength of our range of leisure vehicle grab handles, we have adopted a test recommended by the National Caravan Council.

The grab handle is placed on the test cradle, once in a horizontal position, & once in a position 60 degrees to the vertical. A webbing strap of 4” maximum length is placed along the body of the handle in a central position. A weight of 125 kg is then placed on the handle in a straight vertical pull for both handle positions. This is maintained for a duration of 15 minutes for each position. After the test the handle is allowed a period of 24 hours to normalise back to original shape, this is assuming the handle passed the test without component/fastening failure.

Often we exceed the 125kg mark, and in the past have tested up to 170kg hanging from a grab handle moulding without breakage. Of course this test can be adapted and weights adjusted accordingly to test the strength and flexibility of any component you desire.
