Custom cable-Commonly Supported by Custom Cable Manufacturing

Our modern worldComposite cable depends on the accurate and reliable transmission of energy and data。 Believe it or not， the technologies that support these transmissions are amazingly simple in terms of technology， however， requires sophisticated production processes in order to create the most reliable wiring and cables for a variety of different applications and industries。 The entire industry of custom cable manufacturing has arisen simply to provide these capabilities to the general public。 Here are 7 of the most common cabling industries。

1。 Telecom - When you pull out your smartphone to check your email， check Google Maps， or look up that actor that was in that thing， you rely on wireless or 5G networks。 Or， if you use your laptop to access the Internet， you often do so over ethernet or fiber optic cables。 Ultimately， all of those networks are powered by customized cables designed to transfer digital information quickly and accurately。

2。 Public Utility - From transmitting power to a municipality´s general public， or ensuring the accurate timing and powering of common street lights， public utility is another one of the big consuming industries of custom cable。

3。 Aerospace - The wiring in the instrument panel of an airplane， from a single engine bi plane to an F-16 fighter jet， can be up to miles in length from if strung together end to end。 This wiring is often complex and requires extremely specific requirements to aid in the installation and maintenance of the aircraftCustom cable。

4。 Military & Defense - Every branch of the military has a use for wiring and cabling。 From providing power to an overseas military base or outpost， to providing secure and high fidelity strategic communications to key units in the field， having reliable wiring that can perform in some of the most rugged environments in the world is critical to mission success。

5。 Medical - The cabling and wiring necessary for hospital and healthcare applications also have very specific requirements。 For instance， many medical instruments must be sterilized， a process that involves extreme temperatures and moisture， two things known to break down the integrity of electricity and signal conducting wires。 Medical wiring and cabling needs to be able to withstand repeated exposure to a sanitizing machine。

6。 Public Safety - From the wiring in the dashboard of a police cruiser or ambulance， to the various communications technologies， public safety is a frequent purchaser of wire and cable。

7。 Industrial Control - Imagine an automotive production line， and all of the machinery， from the robotic arms used toMedical cable assemble parts to the vehicle´s frame， to the robots used to deliver and replenish inventory to the assembly line， the wire and cable needs of major industrial applications and manufacturing。

Die Casting - Advantages and Disadvantages

Die casting is adie casting machine process inMulti slider die casting machine which molten metal is forced under high pressure into mold cavities。 The metal hardens to get a desired shapedie casting machine。 In recent times， plastic molded parts have replaced die-casting， as they are cheaper and lighter than die cast parts。 Die-casting can be done using a cold chamber or hot chamber process。

About Die casting Process
widespread non-expendable technique in which metal are forced into the mold cavity under high pressure。 Die casting mold that are known as dies can be used repeatedly to produce castings in a variety of sizes， shapes and wall thickness。 The mold cavities are designed with intricate designs that enables in producing complex shapes with accuracy， surface finish and attractiveness。。

History of Die Casting

In theMulti slider die casting machine early days of die casting only low-pressure injection method was used， but today high-pressure casting techniques like squeeze casting and semi-solid die casting methods are use to cast more than 4500 pounds per square inch。 Initially， only tin and lead were die caste， but now magnesium， copperzinc die casting and other alloys are also to cast using this highly popular process。

Die Casting Process

In this process molten metal or other materials are forced， under high pressure into the cavities of the steel mold。 Dies are two part molds that are made of alloy tool steel - The fixer die half and the ejector diezinc die casting half。 The die or mold is fabricated with the impression of the component that is to cast。 There are four types of dies:

Single cavity to produce one component
Multiple cavity to produce a number of identical parts
Unit die to produce different parts at one time
Combinations die to produce several different parts for an assembly

The molten metal is injected into the die under high pressure and high speed， which helps in producing a casting that is smooth and precise as the original mold。 The pressure is maintained on the mold until the hot metal solidifies。 When the metal is hardened， the die is opened to remove the casting。

There are several variations on the basic process that can be used to produce castings for specific applications。 These include:

Squeeze casting - A method by which molten alloy is cast without turbulence and gas entrapment at high pressure to yield high quality， dense， heat treatable components。

Semi-solid molding - A procedure where semi-solid metal billets are cast to provide dense， heat treatable castings with low porosity。

Alloys used

Aluminum， copper， lead， zinc and tin based alloys are predominantly used in die-casting。

Automation

In modern day， sophisticated s are used that ensures consistent quality control。 Every machined die-casting differs in the method in which molten meal is poured into the die。 Automations are used to lubricate dies， pour the metal into the chamber， etc。 Two processes called the hot chamber and the cold chamber methods are used for die casting。

Applications

Die casting is most suitable for casting medium sized parts with complex details。 Die-casting is the largest casting technique that is used to manufacture consumer， commercial and industrial products like automobiles， toys， parts of sink faucet， connector housing， gears， etc。 Most die castings are done from non-ferrous metals like aluminum， magnesium， etc。

Advantages

Economical process that can be used for a wide range of complex application
Parts have longer service life， dimensional accuracy and close tolerance
Post machining can be totally eliminated
A process that can be fully automated
Mold can be use repeatedly。

Rubber O-Ring-Silicone RTV Rubber Moulds And Mould Making Compounds

RTV-2 silicone rRubber Gasketubbers are pourable， spreadable or kneadable compounds， which will crosslink in the presence of a second component to form flexible rubbers。 They are outstanding as mould-making materials because of their excellent properties:

• Easy to use

• Excellent release properties

• Accurate reproduction of surface details

• Good heat resistance

• Little or no shrinkage
ubbers can also be use for encapsulation and sealing， or for making flexible parts。
ubbers always consist of two components， namely the rubber base itself and a catalyst， or the components A and B。 They are cured or vulcanised at room temperature (RTV= room temperature vulcanising)。

Different grades are available， with different properties suitable for a wide range of applications。 They can be classified according to the following criteria。

1。 Vulcanising system (condensation-curing or addition-curing)

2。 Consistency (pourable， spreadable or kneadable)

3。 Mechanical properties of the curedCustom Mold Rubber Parts rubbers (e。g。 tear resistance and elasticity)

Condensation-curing RTV-2 silicone rubbers

These cure at room temperature after addition of catalyst， volatile alcohols being liberated during the reaction。 Shrinkage occurs， which is completed after about a week。 Although not very effective， the vulcanising process can be speeded up by heating。 The temperature should under no circumstances exceed 70oC。 It is also most important that freshly made moulds， i。e。 which still contain the alcohol produced during the curing reaction， are not subjected to temperatures higher than 80oC， since this would cause a loss of elasticity and softening or stickiness of the silicone rubber (see also Mould pre-treatment)。

Addition-curing RTV-2 silicone rubbers

These vulcanise without the formation of reaction products， so that there is practically no shrinkage。 The cured rubbers can therefore be used immediately after they are fully cured。 Vulcanisation can also take place at higher temperatures (up to 200oC) which greatly reduces the required curing timeRubber Seal。 In this case however， one must take the high coefficient of thermal expansion of silicone rubber into account。

Cleanliness is especially important when processing addition-curing RTV-2 rubbers， since the platinum catalyst can lose its power through contamination。 Catalysts used for condensation-curing silicone rubbers， for example， can interfere with vulcanisation already in small amounts。 Furthermore， vulcanisation of addition-curing rubbers can be delayed or completely prevented if they are in contact with certain materials such as natural and synthetic rubbers， PVC， amine-cured epoxy resins， plasticine， adhesives， soldering tin etc。 Preliminary tests are therefore vitally important。

Storage stability

RTV2 silicone rubbers will remain in usable condition for at least 12 months， provided they have been stored cool and dry， in tightly closed containers。 The T series of catalysts have a shelf life of at least 6 months in closed containers， and should be protected from heat and moisture。 All containers should be tightly re-sealed every time some of their components have been removed。
ubbers and food regulations

Finished products made from addition-curing silicone rubbers are suitable for food contact applications in compliance with food regulations。

Condensation-curing RTV-2 silicone rubbers

These are vulcanised by adding a liquid or paste-like catalyst。 The pot life of the resultant mix， as well as its vulcanising time， will vary between a few minutes and several hours， depending on the type of catalyst and the amount used， the ambient temperature and relative humidity， as well as the amount of movement in the air。 Optimum characteristics of the cured rubber can only be achieved if a suitable catalyst is used in the prescribed amounts。

Addition-curing RTV-2 silicone rubbers

Here the mixing ratio for components A and B is fixed and must be adhered to precisely in order to achieve the desired end product properties。

Preparation of components

All pourable components should be stirred thoroughly before use to ensure even distribution of the filler。 Stirring also improves flow in higher viscosity systems。

Mixing of components

Even mixing of the rubber base and catalyst (in the case of condensation-curing rubbers) or the components A and B (in the case of addition-curing rubbers) is easily achieved for pourable and spreadable compounds， using a spatula。 Larger batches are best mixed with a mechanical stirrer。 Kneadable compounds can be mixed by hand， on the rolls or in a compounder， depending on the size of the batch。

Removal of entrapped air

To ensure bubble-free moulds， pourable mixes should be deaerated under vacuum。 The catalysed mix is poured into a vessel so that it is no more than a quarter full。 A vacuum of 10 - 20 mbar is then applied which initially causes the mix to rise， usually collapsing before the vessel´s rim has been reached。 If， however， there are signs that the mix will run over， a small amount of air is introduced and the process is repeated until the mix collapses。 Evacuation is discontinued immediately afterwards， in other words the mix should under no circumstances be evacuated until no more bubbles form， since certain substances essential for vulcanisation to take place could escape under these conditions。

Application to the pattern

A thickening of the catalysed mix marks the start of vulcanisationRubber O-Ring。 The material should be used well before the pot life has expired， i。e。 whilst it is still in a free-flowing state which makes application that muchRubber Parts easier。 Every increase in temperature reduces the pot life。

The reason inforsunlight readablemation technology is such a success today is because of computers。 The evolution of computers has helped mankind in ways more than one。 Today， the most complicated work is done in a matter of few secondsAll in one computer， all thanks to the computer technology。 We， humans have become totally dependent on computers because we use it everywhere。 Computers have become an integral part of all sectors， public and private included and the medical sector is no different。

Actually， the introduction of computers in the medical sector has only made the health care facilities more efficient in fulfilling their duties。 From storing data， to helping diagnosing the patients， medical PCs have come a long way to benefit the mankind。 If you are a part of a health care facility and are looking to upgrade your infrastructure then considering fanless medical computers isn´t a bad idea，

On a more serious note， if youpanel PC are considering such PCs then here are 5 things you must know before buying computers for hospitals:

• Computers help storing in important data in a more expeditious manner。 Maintaining registers for all information is a headache。 Computersdigital signage efficiently store data like patients´ personal information， prescriptions， their cases or sicknessFanless pc， and the kind of medication prescribed to the patient。 Also there is no difficulty in retrieving any information at any time。

• Medical computers can be used for the purpose of imaging (MRI， Ultrasound， and CT scan etc。) because it is crucial especially in the process of scanning。 In this process oftouch screen monitor imaging hospitals useIP66 different types of special gadgets to click an image of our different organs and bones as per the requirement。

•Industrial pc Gone are the days， when doctors had to be present near the patient to perform any operations or any check-ups。 Today in the age of this cutting-edge technology， operations have been made computerized。 With the useIndustrial monitor of medical PCs， health care facilities are now using technology and modern methods of treatments， where the doctor doesn´t has to be physically present。 The doctors can perform their duties far from the patient。

• With the help of computers，Video wall internal diagnosis has also been made computerized。 Some cases require the doctor to perform an internal diagnosis to catch the reason behind the patient´s illness。 This diagnosis also helps the doctor understand what the condition of their patients is。 Doctors conduct internal diagnosis throughBox PC computers so that they are sure of their patient´s situation。 Without such diagnosis， delay can happen in the treatment or wrong treatment may be given to the patient leading to serious consequences。

sintered metal-Test Strips for Carbon-Fired Metal Clays

Ever since I´ve sintered metalbeen using carbon-fired clays， I have become a big advocate of test strips。 A lot of work can be wasted without the information that they provide。

Test strips give clues to how completely sintered your piece is， and how good your firing schedule is。 There are so many variables to working in carbon-fired metal clay， it is often difficult to arrive at a proper firing schedule just by following the manufacturer´s suggestions。 Many times you need to customize your own firing plan。

Another use for test strips is as a "witness strip" (a term coined by Mardel Rein， owner of Cool Tools and expert on firing metal clays and troubleshooting)。 A witness strip is fired alongside your piece。 Upon removing your work after firing， you can perform tests on the strip， which will give an indication as to what is going on inside the piece you fired it with。 If it is under-fired you will be able to re-fire the piece。 This isn´t a substitute for testing to arrive at a firing schedule。 This is a technique to do after the firing schedule is already determined， anytime you would like to be informed about a particular piece or group of pieces you are firing。 Gordon Uyehara describes this use for test strips in his excellent book， Metal Clay Fusion。

So， how do we "read" a test strip?

For this article， I talked with Bill Struve， inventor of BRONZClay and COPPRClay， and owner of Metal Adventures， manufacturer of those brands。 Bill provided me with a wealth of information and also directed to me Mardel Rein´s very informative Learning Center page about firing bronze metal clay。

There are many tests you can perform on a metal clay strip。 The first one is done after removing the strip from the carbon。 Drop it onto a steel bench block。 It should make a particular type of ringing sound， very metallic。 If it has a dull sound or a "clunk"， something is wrong。

The next test is topowder metal bend the strip。 This test is designed to help determine if the piece is sintered enough to be malleable。 You bend the strip into a tight "u" shape， approximately。2 inches (5 mm) inside the "u"。 During this test， the outside surface of the strip is stretched， while the inside is compressed。 The strip should not crack， tear or break。 Thicker pieces will crack or break more easily than thin， so that is why test strips are done at a thickness of 4 or 5 cards-sort of a happy medium thickness。

The last test is to mix a tiny bit of detergent into a small amount of water， then place a drop of thispowder metal water on the strip。 The water should not be absorbed*， but sit on top of the strip。 This is because with the progression of sintering， the piece becomes less porous。 The water test indicates a "closed" porosity。

*This test will indicate a relatively full sintering。 It is possible for the strip to pass the bend test but not this test。 Not passing this test does not always indicate a problem with your piece。 But if you are looking for full sintering， this is a good test。

Another test that can be performed on a strip is to hammer it really hard。 The stripsintered metal should not crack or break。
