Case Constructions - What's the Difference?
In order to arrive at the best possible solution when it comes to shipping cases, custom cases and other durable packaging designs, understanding the basics about the types of constructions that are used can help a lot. These days, many different processes are used to create high quality cases; depending on which characteristics are important to you, one kind of construction may work better than another. To help differentiate between the different constructions that are available for carrying cases and other containers today, please take a look at the following brief overview of the most common types of case constructions.
Rotational molding - often referred to as rotomolding - is a popularly used process in the package design & development industry. A heated mold melts down high-density plastic - often polyethylene - forming a puddle. The mold is then slowly rotated over a period of time; meanwhile, the melted plastic sticks to the walls of the mold. Ultimately, highly durable hollow plastic containers are manufactured.
Blow molding is another very popular method for creating custom cases and many types of business to business packaging solutions. With this process, plastic is melted down and formed into a preform or parison, which is a tube-like form with a hole on one end. Pressurized gas - usually air - then expands the melted plastic, pressing it to the mold cavity until it cools and hardens. The results are lightweight carrying cases and other similar products.
With fabrication processes, durable packaging solutions and other types of industrial supplies are often manufactured using ABS extrusions with injected mold components. Frequently, custom cases are designed by taking ABS sheet panels and cutting them into custom sizes. This allows for precise measurements and shapes to be accommodated for, providing unique and more usable products.
In some instances, the unique properties of aluminum can help create specialized shipping cases, transit cases, carrying cases and other necessary items. Aluminum can be cut and bent into a wide array of forms, but it's aluminum's special properties that make these cases truly custom. Excellent heat conductivity, better grounding characteristics and great tensile strength all converge to make aluminum cases a natural choice for many applications and situations. Best of all, aluminum is cheap and easy to work with, making for more affordable products.
Many of today's top containers are manufactured with vacuum forming. In this case, a sheet of plastic is heated up to the appropriate forming temperature. Then, it it stretched out onto - or into - a mold, where it is held in place with a vacuum. The vacuum is created between the surface of the mold and the sheet of plastic, allowing for greater control and precision during the manufacturing process. Many of the most versatile and durable carrying cases on the market today have been manufactured using vacuum forming, and many other types of equipment supplies are produced using this unique and flexible process.
Basement waterproofing is both an art and a science. Contractors can waterproof new or old basements. Basement waterproofing is defined as preventing water from penetrating into your basement area. Use Basement Waterproofing and Crawl Space Moisture Control If you have a wet basement or crawl space moisture problem of any kind. Companies can help seal your basement and prevent expensive structural damage to your home's foundation.
In the past, drainage systems were not very efficient. Furthermore, new drainage systems can provide you with tremendous peace of mind with a Lifetime transferable warrantee included with some patented systems. Many systems come with lifetime transferable warrantiesFormenbau-spritzguss.de. Learn more about professional waterproofing systems and do-it-yourself systems. This approach ensures you the best waterproofing systems and solutions available.
Concrete blocks, particularly cinder blocks, are more permeable to water vapor than poured concrete. Concrete paints, waterproofing sealers or paint like coatings are a temporary fix only. The problem of foundation crack repair and concrete crack repair has troubled and frustrated homeowners and builders for decades. Hydraulic Cement and these types of cement based products are a huge problem because it costs approximately 4 times the original product cost to remove them and decontaminate the concrete due to routine failure. I always tell people to stay away from hydraulic cement.
Basement Waterproofing more often than not involves some sort of concrete or foundation repair. The drain tile is a system that is built on the outside wall of your foundation and diverts water through a ground drainage system away from the basement walls. In short, you should begin by keeping as much water away from the foundation of your house as possible. Also, gutters contribute to surface water running down next to the foundation walls. Many homeowners are under the assumption that their foundation has indeed been waterproofed when in fact it has only been damp proofed. Cracks in your homes foundation walls or slab are serious. Basic methods of foundation waterproofing include sump pump installation. As the foundation settles, stress cracks appear. This increases the water pressure on the foundation.
Repair cracks permanently with low-pressure crack injection. Repair holes in a concrete or concrete block wall in the same manner. Learn what is causing your basement water problems and the methods for a wet basement repair. This is one of the most important steps in the repair job.

Mold can grow almost anywhere there is water damage, high humidity, or dampness. Mold needs three things to grow: food, water, & the right temperature.... Mold and mildew, fungi, bacteria, and dust mites flourish in high humidity (over 50%). Mold spores cause allergies, asthma, airways infections, and other health problems, particularly in children. Wet basements have excessive mold and mildew.
The construction industry is full of products that are designed to keep your basement dry. If your builder built the structure properly this should be all of the basement waterproofing that you will need, but this doesn't always happen. Does your home need Basement waterproofing to stop leaks? Make sure you use a professional contractor to do your job.
