Typical application examples and the ways to apply the antifriction coatings
Applying the LIP range
The type of materials and applications encountered are numerous. and it is impossible to give hard rules on application due to the numerous permutations of surface type, material shapes and process issues (production or aftermarket) so we recommend you get in contact if you have a specific problem you need help with. On this page are just a few examples of how we can problem solve for customers.
The automotive interior trim business is such a that there is a huge variety of part design and material combinations, so managing the product selection and application process can be challenging. Our general product selection guide is show opposite but we always suggest you communicate with us directly to make sure you have all the information before proceeding
Leather & Vinyl Seating Noise
AC612/21 is the ‘go to’ product for any leather or vinyl stick-slip applications and leather creaking issues; the product can even be used on some Class A surfaces as it is virtually invisible in thin layers. AC612/21 is the best for larger surface areas as it can be applied with a sponge or cloth. For high pressure contact areas, the PEOX DF could be a second option as it has a higher solid content and will cope better than AC612/21 when contact pressures are higher. PEOX DF is also preferred by customer for very small surface area applications.
Car Door Handle Ticking
Some door handles can produce ticking or creaking sounds when gripped by customers. On the example below the handle fascias were clipped into position and so it was a plastic on metal noise issue. AC F-27 was applied as a containment to the plastic side until the problem was designed out by the automotive tier one. The customer considered using a self-adhesive felt but F-27 was chosen as an easier solution even though there is a short drying time associated with the F-27 dry film product.
Centre Console Twisting
A tier one supplier had a problem with a large centre console designed for an SUV that was twisting while the vehicle was in motion, which created a creaking noise. The centre console consisted of two ABS muoulds heat welded together. It was the friction between the two ABS surfaces that was generating the problem. PEOX DF was chosen to be applied in the areas of concern between the parts before the hot welding process and this corrected the problem.
An automotive manufacturer needed assistance as a EPDM seal was causing noise when a new design of vehicle was in motion on certain types of uneven road surface. The design of the rubber seal was such that two overlapping seals were causing a popping sound and low speeds. An application of our AC602/2 to one of the surfaces prevented the noise occuring until a redesigned seal could be introduced before start of full vehicle production.
Vehicle Headrest Stems/Posts
This is actually a headrest movement issue, not a noise problem. AC612/21 was not originally designed for this application but has solved a big headache for the automotive market. Some seat/headrest designs require a lubricant to ease the movement of the headrests up and down. Applied directly to the metal stems/posts, AC612/21 dries to leave a think layer of solids ensursing a smooth movement but is dry to the touch.
Moving Plastic Parts
Moving plastic parts can be a problem in automotive interior trim. The ability to achieve a smooth movement with zero or minimal noise can be a challenge. Where tolerances are tight or there are design problems that cannot be overcome, an antifriction coating such as F-27 can assist with reducing the friction between plastic parts. The thicker, more viscous AC644-W is also useful to enable sliding mechanisms to more easily interact.
Selecting a product from the range proving difficult?
If you have a noise issue, we recommend you get in contact before choosing a product, especially if you are an automotive manufacturer or parts supplier. Choosing the correct product can be tricky if you are new to the range plus our experience staff help if you have to select a product with manufacturing application of a chosen product in mind. Remember only one of a the two surfaces that are creating the noise need to be treated; however process issues can sometimes dictate which surface will be chose for application of a coating.
If after reading the information available about our products you cannot find a suitable product for your application then please do contact us as we have some industry partners that could assist with a product from a different range.
