What are Aluminium Extrusions?

Extrusion is a process used to create objects of a fixed cross-sectional profile, of solid round, square or rectangular shapes, to L shapes and T shapes, tubes and many other different types. Metal is pushed through a die of the desired shape using either a mechanical or hydraulic press, resulting in the finished product. The cavity in which the raw material is pressed is lined with a wear resistant material which can withstand the pressure that is created when the material is pushed through, making extrusion possible without deforming or tearing the metal.

Aluminium extrusion is generally used in the manufacture of windows, doors and balustrades, but is also found in thousands of other items like vehicle parts, truck trays, boats and other marine products and refrigeration, etc to name a few.

Two advantages of this technique over other manufacturing processes are its ability to create very complex cross-sections, plus being able to work materials that are brittle, because the material only encounters compressive and shear stresses. It also forms finished parts with an excellent surface finish. Extrusions often minimise the need for secondary machining. They are not of the same dimensional accuracy or surface finish as machined parts, however, the process produces a wide variety of cross-sections that are hard to produce cost-effectively using other methods.

Extrusion may be continuous (producing indefinitely long material), or semi-continuous (producing many pieces). The minimum thickness of steel is about 3mm, whereas aluminum and magnesium is about 1mm. The extrusion process can be done with the material hot or cold.

Metals that are commonly extruded:

* Aluminium is the most commonly extruded material and can be hot or cold extruded
* Brass is used to extrude corrosion free rods, automobile parts, pipe fittings, engineering parts
* Copper pipe, wire, rods, bars, tubes, and welding electrodes
* Lead and tin pipes, wire, tubes, and cable sheathing
* Magnesium is used in aircraft parts and nuclear industry parts, and is about as extrudable as aluminum
* Zinc rods, bars, tubes, hardware components, fittings and handrails
* Steel rods and tracks -Usually plain carbon steel is extruded, but alloy steel and stainless steel can also be extruded
* Titanium is often used in aircraft components including seat tracks, engine rings, and other structural parts.

Clean Metals for Recycling

The cleaner that a metal is when it’s taken into a scrap metal yard to sell, the better price it will fetch per kilo, as foreign matter is costly to clean off, so this product will always be penalised accordingly in terms of the price. By this we mean no concrete, screws, glass, paper or any other foreign material attached.

All the metal we buy is processed by cleaning any non-metallic off it as required, cutting it into smaller pieces, and then it is put through a baling press to maximise the weights for export to South East Asia, where it will be melted down and manufactured into new products.

The Extrusion Process

The process begins by heating the material (for hot or warm extrusion). It is then loaded into the container for pressing. A dummy block is placed behind it where the ram then presses the material to push it out of the die. Afterward, the extrusion is stretched in order to straighten it. If higher quality properties are required then it may be heat treated or cold worked.

Cold extrusion is done at or near room temperature. Advantages of this over hot extrusion are the lack of oxidation, higher strength due to cold working, closer tolerances, good surface finish, and fast extrusion speeds if the material is subject to heat for a short period.

Spider Veins – Cause and Treatments

Sometimes, you may have noticed red and blue blood vessels visible through your skin. Have you been a little embarrassed or worried about them? Have you wondered? They are known as spider veins. Here, we will discuss the causes and various treatments of spider vein.

What causes spider veins?
Spider veins are a mild manifestation of venous reflux disease. This means a small, tangled groups of blood vessels that are found just beneath the skin surface. The veins are slightly dilated, and resemble tree spider webs or branches, and are normally spread out on the legs and feet.

What are the risk factors?
Spider vein risk factors are similar to those associated with varicose veins, and include advancing age, obesity, occupations requiring extended periods of standing, hormonal changes and heredity factors (weak vessel walls). One can also develop spider veins because of weak vessel walls or from exposure to ultraviolet rays.

Considering the risk factors, some people will be more prone to this problem than others. For example, if you work as a surgeon, a nurse or a teacher, chances are higher that you might develop spider veins. Similarly, for people with a family history of weak vein valves, the probability of developing spider veins is also high. The same applies to hormonal changes, which generally occur during puberty, pregnancy and menopause.

The exact cause of spider veins is yet to be established. Existing risk factors can be divided into two wide sub-divisions, i.e. acquired causes and congenital. In congenital causes, is Maffucci’s syndrom, port-wine stain and hereditary hemorrhagic telangiectasia (also known as osler-weber-rendu syndrome), among others. The acquired causes include chemotherapy, acne rosacea and lifestyle/occupation risk factors (as mentioned above).

Spider vein symptoms
Spider veins can be painful in some cases, generally accompanying cramping and aching. They often result in a feeling of heaviness in the legs, and burning, throbbing or tingling feelings. In addition, symptoms such as itching, fatigue and swelling can also be experienced. In advanced cases, this condition can establish ulcers, large sores and phlebitis. However, spider veins are noticed by their appearance in a majority of incidences.

Tests and Diagnosis
Doctors generally use non-invasive diagnostic tests to diagnose this condition. These tests are perfectly safe and painless, with no needles, scalpels or medication needing to be involved. The entire procedure is normally very brief, and probably won’t take more than one hour.

There are three main things that doctors seek to answer with these diagnostic tests. Firstly, they seek to establish any evidence of deep vein blood clots. Secondly, they ascertain whether the veins are functioning properly. And lastly, they test the Greater Saphenous Vein (GSV) to determine whether it is working well.

A competent vein specialist will always undertake this exercise before treating your condition. Some of the procedures that you can expect include:

*Color-flow Duplex Exam – This is used to evaluate the anatomy of the affected veins. It determines the direction of blood flow, openings and blockages. This procedure is also important in the process of vein mapping (done for skin deep problems).

*Bi-directional Doppler Exam – This is an ultrasound exam used to determine the speed of blood flow and whether it pauses during normal breathing. It also identifies whether the veins are working properly.

*Photoplethysmography – Phew! Don’t let this complicated medical term intimidate you. Photoplethysmography is basically a diagnostic procedure that determines the efficiency of your calf muscle pump.

*Pressure Calf Exam – In performing this exam, you’ll be asked to lie facing upwards with legs raised higher than your chest. This diagnostic procedure seeks to identify any vessel blockages.

Treatment
After establishing the nature of your problem, the doctor can then recommend the best treatment plan for you. There are several available options:

Sclerotherapy
This procedure involves the doctor injecting a saline solution into the affected veins. This solution then damages the affected vessel walls, causing them to swell and seal shut. Within several weeks the scar tissue will fade. The procedure takes around thirty minutes, and has only mild side-effects. And although the injection may be a bit painful, the stinging sensation is usually gone within a few minutes.

Laser & Intense Pulsed Light
This treatment option employs the use of a specialized device that focuses laser energy to damaged tissue. The procedure only takes 20 minutes, and has minimal side-effects.

Natural Remedies
Natural remedies can mean the difference between undergoing medical procedures or not, and are valuable alongside medical treatment. Some of the recommended herbal remedies include:

*Horse Chestnut Seed – Studies show that this seed helps to improve blood circulation in the legs thus strengthening the veins and capillaries.

*Bilberry Extract – This herbal extract stimulates new capillary formation thus strengthening the capillary walls.

*Butchers Broom – This herb strengthens veins.

*Gotu Kola – A very effective extract which addresses venous insufficiency, foot swelling and water retention. It therefore provides a good solution to spider veins found on the legs.

*Distilled Witch Hazel – This is directly applied on the affected areas using a cotton ball. Numerous clinical studies have shown that this extract can help strengthen blood vessels.

Caution: For health safety purposes, do not start using any herbal remedies without consulting a qualified doctor.

Spider veins prevention
Two of the most important things regarding the prevention of spider veins are eating well and getting regular exercise. Eating a diet higher in fresh, raw fruits and vegetables than meat and convenience food is crucial, and if your job requires you to stand for a long time, you should regularly shift your body weight from one leg to another as well as standing evenly balanced.

To sum things up, the procedure of a spider vein removal is chosen by several key factors. Your specialist will choose the optimum treatment options based on the results obtained from the diagnostic tests. We hope that this article will provide all the necessary guidance you need in addressing this problem.

Tips for Kids Parties

Parties for children have come a long way in recent times due to more options, more expense and more expectation placed on an event that runs for only 2-3 hours. Working in the kids party industry for 15 years, I’ve seen every kind of party from the informal backyard gathering to a virtual carnival with everything imaginable hired.

A children’s party doesn’t need an event planner or a big budget to be wonderful. I want to give you some sure-fire tips to get the party started and the kids really enjoying themselves.

1. Stick with tradition. Children feel comfortable when predictable elements appear, and if they’re overlooked, it won’t go unnoticed! Must-haves are: Food, birthday cake, and the all important Party Bag! If you provide at least these three things, you have a party.

2. What games to provide. There are innumerable options: Party games; hire an entertainer or activity or have the party somewhere that will entertain the kids for you. The Golden Rule is: DON’T OVER-DO IT!

Just one or two structured games are more than enough. Remember, children will be expected to eat now, cut the cake now, watch the gifts being opened now, etc etc.. If you throw in entertainers, activities and games, children may quickly be overwhelmed, plus the party whizzes by without the kids having a chance to actually play with abandonment.

3. Play time: This element should be the top party essential. Factoring time for the kids to run about, play, talk and laugh with one another is golden. It suits children of all ages and capabilities, and -, it’s free!

4. Age-appropriate entertainment. This suggestion may seem like a no-brainer, but I have attended many parties that can have children feeling bored or bewildered. For example, hiring a magician-clown for two-year olds left most of the children terrified. Another example is a bowling party for four-year olds. The kids had no interest in being competitive and after several bowls, the novelty had absolutely worn off. Even Pass-the-Parcel can cause distress when played with kiddies who are too young to realise they haven’t missed out, they just have to wait their turn. When you are hosting a party with mixed ages and genders, there’s a wide range of entertainment that appeals, such as jumping castles and balloon-twisting.

5. Relax! When planning your party, plan with your child and use your instincts – you know what they’ll enjoy the most. On the day have a mini run-sheet so you don’t forget anything, like when to put the party pies in the oven or to hand out the party bags.

And lastly, enjoy YOURSELF too…after all -it’s a party!

All the best!
