乙烯基花样包装方法分享

2019-05-13

Over the years we've had some interesting objects come in to be wrapped. Vehicle interior parts, tool cabinets, helmets, an X-wing jet pack and a skeleton sled used in the Winter Olympics are just a few that come to mind.

多年来,我们逐渐再包装一些有趣的东西,汽车内部部件、工具箱、头盔、x翼喷气背包和冬季奥运会使用的骷髅雪橇...这只是我想到的一些。


Each of these items was a fun change-up from the vehicles and trailers that we normally wrap. What doesn't really differ though is the approach to wrapping unique items. Whether you're wrapping a van or a jet pack, the techniques to wrap either one are basically the same.

每一项都是一个有趣的变化,从我们通常包装的车辆和拖车。但真正不同的是包装独特物品的方法。无论你是包装一辆货车还是一个喷气背包,包装它们的技术基本上是一样的。

Prep

准备功课


No matter what object or vehicle you're wrapping, prepping the object properly is the first step. Start by removing any parts that you can for an easier and cleaner install. All objects need to be thoroughly cleaned to remove any adhesive, oil or other surface contaminants. If necessary, a light coating of 3M Tape Primer to promote adhesion can also be applied.

无论包装的是什么对象或车辆,首先要准备好被包装的物体。尽可能的删除任何没必要的部件,您可以更容易和更快速的包装。所有物体都需要彻底清洗,以去除任何粘合剂、油或其他表面污染物。如有必要,也可采用3M胶带底漆轻涂,以增强附着力。


Beyond prepping the surface of your object, you should also gather together your tools. Depending on your material, you should have the right squeegee for installation. A heat source and proper finishing tools should also be on hand.

除了准备对象,还应该准备好工具。根据你的材料,你应该决定是否需要橡皮清洁刷安装,或者一个热源和适当的整理工具也应该在手。 


Another step is to apply masking tape to any high-surface-energy objects that you are not wrapping. During installation this will keep the vinyl from sticking to these objects as aggressively.

另一个步骤是将遮蔽胶带应用于任何未包裹的高表面能物体。在安装过程中,这将使乙烯基材料不会粘在这些物体上。


Prior to application you should measure or fit the vinyl to the object and cut away any excess material before you start wrapping. Doing this not only gives you scraps that you can possibly use later, but it also removes excess material that will just cause issues as you're wrapping.

在使用前,你应该测量或安装在物体上的乙烯基,并切断任何多余的材料,然后开始包装。这样做不仅能让你得到以后可能会用到的边角料,而且还能去除包装过程中会产生问题的多余材料。 

 

Material

材料


Be sure to choose the right material for the application—interior/exterior, long-term or short-term, deep concave or compound curve areas, etc. Also choose a vinyl that works best with the high or low surface energy of the object you're wrapping. Textured plastic has a low surface energy and will require a vinyl with a more aggressive adhesive while painted metal has a medium to high surface energy and a less aggressive adhesive will stick fine.

一定要为包装对象选择合适的材料——内外、长短、深凹或复合曲线区域等。还可以选择乙烯基材料,这种材料对你要包装的物品效果最好。有纹理的塑料具有较低的表面能量,将需要乙烯基与更具侵略性的胶粘剂,而涂漆的金属具有中等至高的表面能量和较低的侵略性胶粘剂会更好一些。


Beyond surface energy, you need to be familiar with the adhesives that come with different film types and how they should be applied. A calendared film may have a permanent adhesive that leaves little room for error and makes lifting and repositioning the material very difficult. Premium vinyl that is repositionable, with a pressure-activated adhesive will be much more forgiving to work with.

除了物体表面,你还需要熟悉不同薄膜类型的粘合剂以及它们应该如何使用。压延薄膜可以具有永久性粘合剂的性质,这种粘合剂几乎没有留下误差的空间,如果包装出现误差是很难把它重新揭开重新贴的。但优质乙烯基是可复位的,与压力激活粘合剂将允许工作有基本的误差。 

 

You should also be familiar with the properties of the film itself. If the material is not laminated, you need to be sure to use the right squeegee and possibly a water and soap solution. If the material is textured, be aware that it's directional and be sure that you apply it in the same direction across the object. Also be conscious of any heating or stretching that could alter the film's texture.  

你也应该熟悉胶带本身的性质。如果材料没有叠层,你需要确保使用正确的橡皮清洁刷,可能还需要水和肥皂溶液。如果材质有纹理,要注意它是有方向的,并确保你在物体上以相同的方向应用它。还要注意任何可能改变薄膜质地的加热或拉伸。

Some materials require water to install properly while others require a dry installation. Know your material so that you know the best approach for the installation.

 一些材料需要水才能正确安装,而另一些材料则需要干燥的安装。了解你的材料,这样你就知道最好的安装方法。 

Pre-Stretch

预拉伸


No matter what object you're wrapping, knowing a few simple techniques will make a huge difference in the final results of your application. One example is the pre-stre无论包装的是什么对象,了解一些简单的技术将对应用程序的最终结果产生巨大的影响。一个例子是预拉伸技术——TCH技术。


In this technique the material is heated, stretched then placed around an object. Once it's placed on the object, with a few inches of overlap at the edges, the material is reheated so that it shrinks back and conforms around the object, much like shrink-wrapping.

在这种技术中,材料被加热,拉伸,然后放置在物体周围。一旦它被放置在物体上,边缘有几英寸的重叠,材料就会被重新加热,这样它就会收缩,并在物体周围保持一致,就像收缩包装一样。 


Because vinyl has a memory to it, stretched vinyl wants to shrink back to it's original shape. However, if the vinyl is over-stretched, especially right to the edge of an object, the vinyl will lift and fail once the vinyl starts to shrink back. By heating, wrapping, then reheating the material you're conforming the vinyl to the object, while also relieving the tension at the edges that can cause failure. When the excess vinyl is cut away, the smooth tension-free vinyl remains around the object with little chance of lifting.

因为乙烯基有记忆,拉伸的乙烯基想要收缩回原来的形状。但是,如果乙烯基过度拉伸,特别是在物体边缘,乙烯基会在乙烯基开始收缩后升起并失效。 通过加热,包装,然后重新加热材料,使乙烯基材料与物体保持一致,同时还可以缓解可能导致失效的边缘张力。所以当多余的乙烯基被切除时,光滑的无张力乙烯基保留在物体周围,几乎没有提升的机会。

There are limitations to pre-stretching with heat. It works fine on gloss, satin and matte materials, but on chrome, brushed metallic and carbon fiber films the heated stretch can cause discoloration or distortion of the pattern.

热预拉伸是有限制的。它适用于光泽、缎面和哑光材料,但在铬、拉丝金属薄膜和碳纤维薄膜上,加热拉伸会导致图案变色或变形。 


Cold pre-stretching works similarly but heat is not used initially before wrapping the vinyl around an object. The vinyl is simply stretched over an object without heat, starting at the most difficult area, then smoothed out. Before taking the material all the way to the edge of the object it is heated to remove any tension right at the edge, then you finish squeegeeing the material to the edge. Because cold pre-stretching doesn't involve as much stretching of the material itself it allows you to use the techniques on a wider variety of materials.

冷预拉伸工作类似,但在将乙烯基包裹在物体周围之前最初不使用热量。乙烯基只是在没有热量的情况下在物体上伸展,从最困难的区域开始,然后平滑处理。 在将材料一直带到物体边缘之前,将其加热以去除边缘处的任何张力,然后完成将材料刮到边缘。由于冷预拉伸不涉及材料本身的拉伸,因此您可以在更多种材料上使用这些技术。 

Triangle

三角形


Another technique that Justin Pate often mentions in his videos is pulling the graphics in a triangle. In this technique you're anchoring the vinyl in an area with minimal tension then pulling the vinyl out toward the edges.

贾斯汀·佩特(Justin Pate)在他的视频中经常提到的另一种技术是将图形绘制成三角形。在这种技术中,你把乙烯基固定在一个张力最小的区域,然后把乙烯基拉向边缘。 


On larger objects the vinyl may be divided into multiple sections as you pull tension out all the way around the object. Depending on the shape of the object you're wrapping, you start at any curves or points and pull the vinyl out at a triangle. The curved point is the tip of the triangle. This distributes the excess vinyl away from the point, eliminating tension, and future failure.

在较大的物体上,乙烯基可以被分成多个部分,因为你把拉力拉出物体周围的所有地方。根据你包装的物体的形状,你从任何曲线或点开始,把乙烯基从一个三角形拉出来。曲线上的点是三角形的顶点。这就把多余的乙烯基从点上分散开,消除了张力,避免了将来的故障。 


If you see wrinkles forming along the edge of an object simply pull at a V away from the wrinkles to create a smooth glass-like surface. All of this pulling and smoothing is typically done before you even start squeegeeing. Once the graphics are smooth and wrinkle free you can simply squeegee the graphics to set the adhesive.

如果你看到沿着物体边缘形成的皱纹,只需从皱纹处拉出一个V,就可以形成一个光滑的玻璃状表面。 所有这些拉动和平滑通常在您开始刮擦之前完成。 当包装光滑无皱时,您只需刮擦图形即可设置粘合剂。 

Relief Cuts

浮雕包装


Another big part of wrapping—especially with unique objects and objects with compound curves—is knowing when to make a relief cut. As you move the vinyl over an object you can feel where resistance is created. If you feel like you're having to force the vinyl it may be best to create a relief cut. This allows the vinyl to separate and move in a new direction without over-stretching.

包装的另一个重要部分——尤其是独特的物体和具有复合曲线的物体——是知道何时进行浮雕切割。当你在物体上移动乙烯基时,你能感觉到哪里产生了阻力。如果你觉得你必须强迫乙烯基,这可能是最好的创建一个救济削减。这使得乙烯基在不过度拉伸的情况下可以分离并向新的方向移动。


These relief cuts may be large or very tiny depending on the object you're wrapping. They are very helpful and it's a great technique to master. Be careful that your cuts are not made too large or too close to an edge. You need to also be careful when pulling against a relief cut that you don't stretch it further causing you to come up short on the object.

这些浮雕可能很大,也可能很小,这取决于你要包装的对象。他们非常有用,这是一个伟大的技术掌握。注意你的伤口不要太大,或者不要太靠近边缘。你也需要小心,当你拉一个浮雕切割,要小心不要过度拉伸导致包装太短。 


When you need to create an overlap—which is essentially a relief cut that remains on the object—Knifeless Tape is a great way to create a straight line without cutting on the vehicle. You can also create overlaps in areas that are not visible in order to speed up installation while creating a lasting finish. If you do need to cut on the object, be sure to use a fresh, sharp blade and a light, steady hand.

当你需要创建一个覆盖层时,这实际上是一个保留在物体上的浮雕切割,无刀胶带是一种很好的方法来创建一条直线而不切割。您还可以在不可见的区域中创建重叠,以便在创建持久完成时加快安装速度。如果你确实需要切割物体,请务必使用清新锋利的刀片。
