John Steel asked:


In the past, automakers designed headlight lenses made from glass so they were limited in the size and shape they could produce. Since then, auto manufacturers began designing cars with plastic headlights. This modification mainly occurred due to the change in the design of cars—cars became lighter and more aerodynamic, plus plastic was by far less expensive to produce than glass. Today this plastic material is the chosen choice because it is very light and can be transformed into unlimited sizes and shapes to satisfy new car designs.

Polycarbonate has its advantages but also has its disadvantages—namely oxidation / discoloration. To the naked eye one cannot tell that these plastic lenses are actually a porous material that expands ever so slightly when it gets hot. Degradation of the lens occurs over time. Having your headlights on or being exposed to the heat of the day causes the pores to open allowing debris from the road to get in. Debris, together with a combination of environmental factors such as the sun (UV rays), smog, acid rain, car exhaust, and harsh chemicals used to wash you car can cause the plastic headlight lenses to become oxidized.

Plastic oxidation leads to lens discoloration, which transforms new, clear, bright, shiny plastic to a dull yellow tint that appears to be foggy, hazy, or cloudy. This process (oxidation), as described above, not only becomes an eyesore but also is unsafe. Because of the degradation of the plastic lens, less light passed through resulting in diminished visibility during night driving. The car owner either had to deal with these cloudy yellow, oxidized headlight lenses posing serious safety issues or purchase expensive replacement headlights costing hundreds or thousands of dollars.

“The Headlight Solution” at www.headlightsolution.net wants the public to know and learn how to restore, clean, polish, and clear those cloudy, yellow plastic headlight lenses on their own without putting more money into the car manufacturer’s pocket. One can restore headlights to like-new condition by taking off the top layer of oxidized plastic. This can be achieved through polishing, wet sanding, or through the use of chemicals. Auto manufacturers would rather you go to them for a headlight repair (charging as much as $150) or headlight replacement ($100-$1,000). The top layer of plastic on the headlights contains a UV polymer that retards or slows down the aging of the plastic lens. Therefore, it is important to use a polish (containing UV polymers) or UV coating to slow down the oxidation or discoloration of the lens. Parking your car in the shade or garage, or maintaining the lens by washing, waxing, and polishing a minimum of every three months, could avoid damage to the headlight lens.

“The Headlight Solution” specializes in headlight restoration. The products we use on a daily basis to renew headlights are indeed the products we sell. Rest assured that when placing an order for any of our headlight restoration kits you are getting the real deal and top quality products. Our business is restoring headlights on used vehicles, as well as restoring the emergency lighting on service vehicles. We not only come to your home or place of business to refinish your headlight lens, but also sell a headlight cleaner or headlight lens cleaner. As a matter of fact, we sell two types of plastic lens cleaners:

1. Basic Headlight Restoration Kit (for light discoloration)

2. Advanced Headlight Restoration Kit (for more severe discoloration)

Both kits work extremely well. Choosing a kit depends on the severity of your vehicle’s lenses. Our kits are very easy to use and do not require the use of special tools or training. Beware of kits that offer backing plates and drill attachments. While they may save time, they may cause irreversible damage due to various drill speeds causing burning or swirls in the plastic lens. First-time users should avoid these kits because it takes skill and practice to control the drill from making these mistakes and possibly slipping off and ruining a perfectly fine paint job.

In our Advanced Headlight Restoration Kit, we even supply a small roll of blue painters tape to mask your headlight to protect your paint job during the restoration process. Along with both kits, one also receives a step-by-step brochure outlining how to clean headlights appropriately to obtain bright, shiny headlamps while restoring optical clarity to your lenses. Both of our kits carry a satisfaction guarantee. If you are not satisfied with either of our products, simply return the remaining contents of the kit for a full refund. If anyone has any questions while reconditioning their headlamps, feel free to email us and one of our trained technicians can walk you through the quick and easy process of headlight restoration.

Plastic bed liners may be better for your truck than an expensive spray on liner. Not just because they’re cheaper either.

Pickup truck bed liners are one of the best ways to keep your truck looking good. You can choose from several types of liners. Plastic bed liners may be the best choice if you really use your vehicle for serious hauling. If you only haul groceries, any liner will do or maybe you don’t even need a bed lining. Often the spray on liner is considered the top choice and they have several advantages. But plastic truck bed liners may be better sometimes and here’s why.

No more dents.

Nothing makes a pickup bed look much worse than a lot of dents and dings. And some kinds of hauling just produces dents. It’s almost impossible to avoid. Here’s where plastic linings really shine. One of these liners is almost impossible to dent. Just the thickness and weight of a good liner is a clue about how tough these liners are. Plastic tough liners absorb shocks that would damage lesser materials. Now the best spray on liners absorb a lot of damage, but they’re more rubbery and not as hard and tough as plastic.

No more scrapes.

The other way to destroy a truck bed is with scrapes and scratches. Of course this kind of damage is bad enough, but the damage is a place for rust to get a start. Rust is the real killer. And unless you keep scratches repaired, you’ll get rust. A great plastic lining will eliminate scratches from any kind of cargo. Think about concrete blocks. No way you can avoid bed damage if you haul a few concrete blocks without a liner. And remember a spray on liner may keep gouges from reaching the bed. But that doesn’t mean the expensive liner doesn’t get scarred up. So a damaged spray on bed liner must be repaired or you live with the damage.

Good looks.

Which leads to the looks factor. A pickup just doesn’t look right without a bed liner. A custom drop in liner looks just as good as a spray on liner. But of course the spray liner is permanent. That isn’t all good since normal wear and tear may make your liner look shabby over time. With a plastic bed liner, abuse it all you want and just pull it out and slip in another at any time.

Cheap is good.

Replacing a plastic liner isn’t such a big deal, since they’re so much cheaper than a spray on liner. The price may be half or less than a spray liner. These liners are cheap protection for your truck bed and easy to maintain or replace. You have a couple of different types to choose from too. The most common drop in bed liners are one piece, custom made to fit a particular truck model. A really good alternative to the one piece model is a custom multi-piece liner. These liners have separate pieces for the bottom, sides, front and tail gate. You get a great fit, an even better custom fit than with a one piece unit. Plus the multi-piece plastic bed liner is easier to ship and still is quick to install and tough too.

A plastic bed liner is a great alternative to a spray on bed liner. Protect your bed from dents and scrapes. Do it a lot cheaper than many other liners too. A multi-piece unit is also easy to ship and fits even better than the one piece units.

Linda Moore asked:


Plastic has, quite literally, become the cornerstone of our society. We make so many things from plastic that it is hard to imagine what our lives would be like if it was never invented. With so many of our everyday products being made of plastic, it is easy to understand why plastic injection molding is such a huge industry.

Approximately 30% of all plastic products are produced using an injection molding process. Of this 30%, a large amount of these products are produced by using custom injection molding technology. Six steps are involved in the injection molding process, after the prototype has been made and approved.

The first step to the injection molding process is the clamping of the mold. This clamping unit is one of three standard parts of the injection machine. They are the mold, the clamping unit and the injection unit. The clamp is what actually holds the mold while the melted plastic is being injected, the mold is held under pressure while the injected plastic is cooling.

Next is the actual injection of the melted plastic. The plastic usually begins this process as pellets that are put into a large hopper. The pellets are then fed to a cylinder; here they are heated until they become molten plastic that is easily forced into the mold. The plastic stays in the mold, where it is being clamped under pressure until it cools.

The next couple of steps consist of the dwelling phase, which is basically making sure that all of the cavities of the mold are filled with the melted plastic. After the dwelling phase, the cooling process begins and continues until the plastic becomes solid inside the form. Finally, the mold is opened and the newly formed plastic part is ejected from its mold. The part is cleaned of any extra plastic from the mold.

As with any process, there are advantages and disadvantages associated with plastic injection molding. The advantages outweigh the disadvantages for most companies; they include being able to keep up high levels of production, being able to replicate a high tolerance level in the products being produced, and lower costs for labor as the bulk of the work is done by machine. Plastic injection molding also has the added benefit of lower scrap costs because the mold is so precisely made.

However, the disadvantages can be a deal breaker for smaller companies that would like to utilize plastic injection molding as a way to produce parts. These disadvantages are, that they equipment needed is expensive, therefore, increasing operating costs.

Thankfully, for these smaller companies, there are businesses that specialize in custom plastic injection molding. They will make a mock up mold to the exact specifications, run it through the complete process and present the completed piece along with an estimate to complete the job to the customer.
