Tape Wrapping Wire & Cable Harnesses Guide
This document describes generic methods for applying insulating, thermal or EMI tape materials. It applies to all tape materials which can be helically wound around a wire and cable bundle. The methods described are typical of industry installations and may or may not apply to customer-specific installation requirements. In-house engineering requirements should always be consulted prior to making any production installation. These instructions are provided as an “idea guide” rather than a rigid requirements document. All procedures described herein have been found to provide good mechanical and electrical performance, however, The Zippertubing® Company cannot guarantee end performance results.Get more news about Wire Harnessing Tape,you can vist our website!
Tape users should be aware that a tape wrap jacketing installation is a highly inefficient and costly harnessing solution. Although the tape materials are extremely versatile and appear inexpensive at the buyer level, the finished assembly cost will generally be high because tape wrapping is a very labor-intensive process. Furthermore, tape wrapping is a “craft sensitive” process and the finished installation can vary from installer to installer. Generally, tape wrapping should be limited to short run lengths, cable branch intersections and cable branch legs. To maximize harness assembly efficiency, long run sections of a cable harness should be jacketed using a wrap-around, zip-on jacket material with tape wrap areas kept to a minimum.
Tapes
You need to define what type of tape is being used and what the purpose of the tape wrap is. Is the material an adhesive-backed, elastic polymer film, a woven fabric or a metal foil? Is it intended to loosely hold a group of wires together so they all follow the same general direction or is it intended to constrict the wiring into the smallest possible bundle diameter and/or provide a secondary performance characteristic? There are specific tape types which are designed to provide additional performance characteristics to cables such as adding abrasion protection, improving dielectric insulation, providing thermal protection, providing EMI shielding or a combination of these. Knowing the intended use will dictate how much coverage is required, how many layers are required and how precise the installation technique needs to be.
Tape Quantity
The most common question customers ask is “how much tape will I need for my project”? This can be a difficult question to answer since no two installations are the same and some material types are thicker than others. Also, EMI and Thermal materials will require greater coverage to perform correctly. The table below provides a rough approximation of the tape length required to cover one linear foot of cable. The values shown are based on mathematical calculations using a 50% overlap, a straight run of cable and using a tape material thickness of zero. Wrapping a cable that has bends in it will increase the quantity of tape required per foot to maintain the 50% coverage. A good rule of thumb is to add 1/3 of the length/foot to all linear tape length values shown in Table 1. Do not fall into the trap of trying to use a wider tape on a small cable to minimize the footage of tape required. Using too wide a tape for the cable diameter will result in large wrinkles and open gap areas which can defeat the functional purpose of the tape as well as look bad cosmetically. Material widths shown in “Red” are generally considered too wide for use on the corresponding cabled diameter.

If the success of your company depends on buying rigid PVC films of the best quality and highest value, then you’ve come to the right place. KASSEL IMPORTS sells and distributes the highest quality vinyl films, manufactured to our customers’ specifications. PVC film is the core product on which our company was built. We continue to supply superior films made to exacting standards. At the same time we provide value to our clientele.Get more news about rigid PVC film,you can vist our website!
PVC film has come to be recognized over the decades as one of the most diverse and valued resins and films commonly available. As a result, PVC is valued for its resistance to caustics, oils, acids, alcohols, and permeability. In addition, PVC film is flame-retardance. It is said to be self-extinguishing.PVC Films are manufactured in a diverse ranges of thicknesses, colors, clarity, heat- and cold-resistance, impact-resistance, surfaces, and embossings. As a result, it can be heat-formed, metallized, coated (colors or adhesive), slit, and die-cut.
Rigid PVC films can be supplied in thick or thin gauges. KASSEL IMPORTS specialization is in THIN GAUGES, roughly from 0.8 mil up to 8 mil rigid PVC. The most common end-uses in this category have been adhesive tapes and decorative films (holiday & novelty).
We also supply thicker gauges of rigid PVC, which are used for packaging (thermo-forming), credit cards, printing & graphic arts. Please ask us about thick PVC films, which are delivered directly from our factory to yours, made to your specifications.Polyvinylchloride Film is commonly called “vinyl” or “PVC” film, or “sheeting”. It has become one of the first thermoplastic resins invented. KASSEL IMPORTS and its predecessor corporations began to import these films from Europe in the 1960’s. Consequently,this is now the legacy of our third-generation enterprise.
There are two broad categories of vinyl film. The first is Rigid (unplasticized, or “UPVC”). This first type of vinyl is used for packaging, adhesive tapes, decorative applications, among other markets. The second category of vinyl film is known as Flexible (plasticized). Flexible vinyl is softer and more pliable than Rigid vinyl. Therefore the uses for flexible vinyl include faux leather, notebooks/file folders, pouches, and similar products.
The biggest use of the vinyl resin is in construction. It is used primarily for pipes and siding. Vinyl resin is also used fences and decks from time to time. The rigid film has been used most extensively in thermoforming (vacuum-forming) packaging. Therefore, this is the basis for innumerable food and pharmaceutical trays, containers and blister packs, with extended shelf-life. These FDA-approved PVC films have been a backbone of that market for decades. Industrial or non-food packaging for household goods, toys, and other consumer retails packs, are also an important and ongoing market for vinyl films. These could be blister cards, clear folding boxes and lids, and trays.

How To use Firesilicone B1 FR, fire rated silicone sealant?
Take care to follow the standard industrial hygiene methods for applying sealants. Make sure to clean the surface and remove all traces of dust and grease.
If the sealant is applied to porous substances, Primer 150 should be used to prime the surface. It is recommended that a preliminary compatibility test be conducted before you proceed.
To enhance the adhesion properties on smooth surfaces, we advise you to use Soudal Surface Activator.
Use a caulking gun as the method of delivery for maximum impact.
As for backing material, we suggest the use of PE backer rods for correct joint dimensions.
Take care that during the application, the atmospheric temperature does not exceed room temperature conditions.
After application, clean the caulking gun with white spirit immediately. If the sealant cures, then it has to be mechanically removed by chipping it off.
Finish the applied sealant properly by using a soapy solution.
Why Choose Thin Porcelain Tiles?
A few years ago, a new trend appeared in the tiles showrooms: the thin tiles. They are made in ceramic, and their weight is two times lighter than a standard tile.Get more news about Thin Porcelain Tile,you can vist our website!
To obtain a professional and clean result, special care should be taken when handling and fixing these tiles.
Until recently, floor tiles have been 8 to 12mm thick and tiles less than 7.5mm were not intended for floors. However, tiles engineered to be thinner have now entered the marketplace. Made of porcelain, they are being marketed as “thin tiles.” Are they the same as their thicker brethren, except thinner? Being thinner they take fewer resources to manufacture and ship, but where and when can they be used?
What are Thin Tiles?
There are three categories of products being promoted as thin tiles. All three are 6mm or less, but there are important differences between them.
In the first category, tiles are formed using the traditional dust pressing methodology. Such products are similar to traditional pressed porcelain tiles, except they are only 5 to 6mm thick and have a lower breaking strength.
In the second category, tiles are formed using a lamina process. Lamina tile products are produced in large, thin ceramic sheets, from which individual tiles can be cut. They are 3 to 4mm thick, are much lower in strength, and bend sufficiently to be installed on curved surfaces.
In the third category of thin tiles, lamina products are reinforced with backing materials. These backing materials are fiberglass or polymeric materials woven into a reinforcing mesh. Fused directly to the back of the lamina products with epoxy or other resin adhesives, the reinforced lamina tiles can be bent further and better resist breakage.
Porcelain panels are unique and versatile building materials that are available in extra large formats and thicknesses. Panels are sized up to 5’x10’ with 3mm-5mm thicknesses for walls and floors, and 12mm thicknesses for countertops. Our designers can help you transform your home using thin porcelain clay tiles that are easy to install, eco-friendly, and guaranteed to last. We carry a unique selection, including products from Florida Tile, Cotto d’Este, and Florim.

How to design parts for CNC machining
To take advantage of the capabilities of CNC machining to the fullest, a designer must follow certain Design for Manufacturing rules. This can be challenging though, as specific industry-wide standards do not exist.Get more news about Desktop Cnc Machine Parts,you can vist our website!
In this article, we compiled comprehensive guidelines with the best design practices for CNC machining. We asked for feedback from industry experts and CNC machining service providers to compile an extensive list of up-to-date information.
We focused on describing what is feasible with modern CNC systems, neglecting the associated cost. For a guide on designing cost-effective parts for CNC, please refer to this article.CNC machining is a subtractive manufacturing technology. In CNC, material is removed from a solid block using a variety of cutting tools that rotate at high speed (thousands of RPM) to produce a part based on a CAD model. Both metals and plastics can be CNC machined.
CNC machined parts have high dimensional accuracy and tight tolerances. CNC is suitable for both high volume production and one-off jobs. In fact, CNC machining is currently the most cost-effective way of producing metal prototypes, even compared to 3D printing.
CNC offers great design flexibility, but certain design restrictions exist. These restrictions are related to the basic mechanics of the cutting process and are related mainly to tool geometry and tool access.
Tool geometry
Most common CNC cutting tools (end mill tools and drills) have a cylindrical shape and a limited cutting length.
As the material is removed from the workpiece, the geometry of the tool is transferred to the machined part. This means, for example, that the internal corners of a CNC part will always have a radius, no matter how small a cutting tool was used.
Tool access
To remove material, the cutting tool approaches the workpiece directly from above. Features that cannot be accessed this way, cannot be CNC machined.
There is an exception to this rule: undercuts. We will see how you can use undercuts in your designs in latter section.
A good design practice is to align all features of your model (holes, cavities, vertical walls etc) to one of the 6 main principal directions. See this rule as a recommendation and not a restriction though, as 5-axis CNC systems offer advanced workpiece holding capabilities.
Tool access is also an issue when machining features with large depth to width ratio. To reach the bottom of a deep cavity, for example, special tools with long shafts are required. This lowers the stiffness of the end effector, increasing the vibrations and lowering the achievable accuracy.
Replacement Exhaust Pipe Information
The most obvious part of the exhaust pipe can be easily seen at the back of any vehicle on the road. Some vehicles incorporate these tail pipes into the design. You may see elaborate pipes, two pipes or even two sets of two.Get more news about Muffler Pipe,you can vist our website!
They may be chromed, customized, very large or very small. Whatever the case, these pipes serve the same purposes in the exhaust system of a vehicle. The first of these purposes is that they allow the exhaust gasses to escape from the exhaust manifold and provide a set path so that they are not trapped in the engine compartment.
Another purpose is to provide a large enough vent that the engine can operate without back pressure. And of course the most obvious purpose and one that nearly everyone knows is that this pipe provides a path through the muffler, resulting in dampening of significant quantities of engine noise. Once you acquired a car or truck, you made an investment that is likely to endure for many years, so bolster that decision by buying top-notch parts and accessories. If an auto part becomes too worn, the sensible solution is buying a well-rated OEM or replacement auto part to keep your car or truck in top running order. If you're in the market for a part as basic as antenna masts or something more advanced like harmonic balancers, PartsGeek is here to help you.
ERGONOMICS IN THE DENTAL OFFICE
Picture the most recent clinical procedure you performed. Are you leaning over the patient or is your back erect? Are you craning your head to get a better view or is your neck relatively straight? Are your hands twisted around or are your wrists level?Get more news about Ergonomic Dental,you can vist our website!
It is not uncommon for dental professionals to find themselves straining in awkward positions repeatedly throughout the day while delivering care to their patients. Unfortunately, this also puts practitioners at a high risk of musculoskeletal problems, including back pain, repetitive motion injuries, carpal tunnel syndrome, and more.
There’s a real cost to this pain, too. RDH Magazine reports that millions of dollars in income are lost every year when dentists must cancel patient appointments because the pain prevents them from working.
The solution to this pervasive challenge is ergonomics: the science of fitting the work to the worker, so the worker doesn’t need to strain to perform the work. Sounds straightforward, right? In dentistry, though, this often means rethinking the basic techniques dental professionals use every day when delivering patient care.
The clinician should always try to face the patient directly during treatment. To maintain a direct view into the oral cavity, ask the patient to turn their head as needed and use mirrors to improve visibility. Hold handpieces and instruments at roughly arm level and keep instruments within a 21-inch radius of the assistant to minimize the need to reach or turn. The overhead light should be positioned slightly behind and to one side of the clinician’s head to minimize shadows. A lightweight head-mounted light can also be an ergonomically friendly lighting alternative.
Ideally, the patient will be in a supine position for clinical procedures; a contoured cervical support cushion can improve the patient’s tolerance for reclining. In RDH Magazine, physical therapist and dental ergonomic consultant Bethany Valachi recommends placing the patient chair back at a 10- to 15-degree angle from the floor. She also suggests asking the patient to scoot to the end of the headrest to eliminate the need for the clinician to lean over the empty space on the headrest.
When treating the upper arch, the occlusal plane should be tilted 15 to 20 degrees from the vertical plane, while when treating the lower arch, the occlusal plane should be tilted about 30 degrees from the horizontal plane. The patient chair should be adjusted so the forearms are parallel to the floor or sloping 10 degrees upward.
Ergonomics should also be a key factor when selecting dental instruments. Lighter, larger-diameter instruments, particularly those with a textured grip surface, are easier to grasp and can reduce the amount of force needed during probing, scaling, and root planing.
EverEdge 2.0 Scaler with ResinEight handle
Additionally, maintaining dental instruments with sharp working edges is critical for reducing hand fatigue. Instruments that are not properly sharpened will require the operator to apply more force to achieve the same result, which can increase both working time and patient discomfort. If sharpening by hand, it’s essential to utilize the right sharpening tools and appropriate technique to avoid hand fatigue and ensure proper instrument maintenance. Of course, a professional sharpening service is always an option too.
AIRFLOW Master Piezon combination air polishing / Piezo tabletop device
Another important tactic for improving ergonomics is establishing a replicable process for treating patients that incorporates a variety of techniques. Guided Biofilm Therapy, for instance, advocates using a combination of AIRFLOW® and hand scaling (among other steps) as a comprehensive approach to preventive care. This not only provides a higher standard of care but also significantly reduces hand stress by incorporating power techniques with hand scaling.
