The most necessary workshops in the automotive industry is a car film, they are designed to protect the car’s paint from scratches, dents, and whatever other damage you could think of. At Oriency Sign, we are dedicated to delivering premium car films for our customers. Today, in “The Focus,” let’s talk about how shrink varies between cast and calendered car films.
An in-depth analysis
Shrink is the characteristic of how much a car film will shrink when heat is applied and the film is placed on a vehicle. This is a make-or-break stat to consider when selecting a car film, as it affects how closely the film bonds to the car. ## The shrink behaviors of different car films There are different types of car films that are divided into cast and calendered films.
Understanding the shrinkage
Shrinkage in is the process in which the car film is applied at a higher temperature. Stretch & mold car films are created using a manufacturing process that gives them the ability to be stretched and shaped once fitted to the car, making it have minimal shrinkage. Another material is calendered car film, which is produced using a compression process and has a relatively high shrinkage.
Shrink behavior by cast and calander car films
The cast car film is recognized for its superior wrapability and durability. Not only do they have minimal shrinkage, allowing them to adhere to the vehicle's curves like it was painted on, they give a professional, clean looking wrapjob. Meanwhile, calendered car films have higher shrink-plasticity, which makes them potentially more difficult to apply, particularly for curved surfaces.
The influence of production on the shrinkage behavior in automotive films
The way a car film is made is a major factor in how it will (or won't) shrink. C… Submitted cast vehicle films are made by casting a formulation onto a planar substrate and curing. Such a film has very little shrinkage and retains its shape well. Calendered car films, on the contrary, are made with a process of "squeezing" the material, resulting in a film with more shrink back.
Investigation of the cast and calendered car films heat shrink properties
It can be seen that shrink behavior represents the major distinguishing factor between casted and calendered car films. Car films have minimal shrinkage allowing for a faster and easier installation. Calendar film on the other hand shrinks more, which can make it more difficult to work with, especially on shaped surfaces. At OriencySign, we provide a variety of premium cast automotive films to ensure the best protection for your car. Select Oriency Sign for all of your vehicle film requirements.
