How Plastic Types Available

The exact number is unclear. Plastic is not only one of the ingredients that made the same way every time. Although the plastic can be broken down into broad types or categories, there are actually thousands of different plastics, each with its own composition and characteristics. One plastic can block the oxygen to reach the food. Other possible but difficult transparent as glass. Or stretch and get back in shape.

That's why plastic is used in many ways: they protect our food, protect our homes, improve our cars gas mileage, keep us dry when it rains ... and many other things.

Plastic is the result of a mixture of chemical and engineering. As innovation marches, scientists and engineers can make new plastic to do more and more things.

So even though the amount is not clear plastic, plastic makers tend plastic into two general groups of classes: thermoplastics and thermosets.

Thermoplastics can be re-melted and basically back to their original state as a way kind of ice can melt and then cooled again. Thermoplastics are usually produced first in a separate process to make small pellets; This pellet is then heated and molded to make all kinds of consumer and industrial products. Thermoplastic including plastic you may be familiar with: polyethylene, polypropylene, polyvinyl chloride, polystyrene, nylon, polycarbonate, and others.

Thermosets are usually produced and formed into a product at the same time-and they can not return to their home countries. They are generally formed using heat and be "set," such as eggs cooked. Thermoset including vulcanized synthetic rubber, acrylic, polyurethane, melamine, silicone, epoxies, and others.

There is another category of plastics:

Engineering plastic ... Has good mechanical properties have been improved and engineered often greater durability. For example, impact-resistant polycarbonate. Polyamides such as nylon against abrasion. Some combination of plastic, such as ABS is very difficult (acrylonitrile butadiene styrene). List of engineering plastics long enough.

Plastic fibers precisely that: a plastic that has been spun into fibers or filaments which are used to make cloth, rope, ropes, fiber optic cable and even body armor. Most plastic fiber is strong, elastic, and stable under heat (so that the fabric can be ironed). Some of the most known plastic fibers are polyester, nylon, rayon, acrylic, and spandex, although there are many more. (Note: sometimes called polyethylene terephthalate polyester-it is also used to make plastic water bottle which can then be recycled into fibers for clothing, such as fleece jackets and t-shirts).

There are many more categories, such as coatings, adhesives, elastomers and rubber, which includes the plastic used in everything from outside the shuttle to food packaging.

Rising Plastics Industry

JAKARTA - Inaplas (Arimatik Industry Association, Olefin and Plastic) record the number of plastic production in the country will grow 7 percent this year. Least advanced plastics industry, depending on the progress of economic growth.

Vice-Chairman of the Business Development Sadiman Inaplas Budi Susanto said, with economic growth of 5.6 percent to 5.7 percent, the growth in the production of plastic this year is higher than the economic growth. It was believed to be due to the existence of the democratic party elections which encourages increasing the amount of plastic consumption.

"With the democratic party, bring plastic consumption. Hire plant-bottle for the food and beverage, food and beverage industry campaign to make rapid progress, 27 thousand people that require 5 percent of plastic," he said in a written statement on Wednesday (16/04 / 2014).

Budi added, the constraint is in terms of the price of raw materials is much more expensive because it is imported materials. But the one hand the current world oil prices fell 10 percent.

"In addition to the elections, it had a positive impact. PLN But the barriers are meeting tomorrow will naikin electricity prices, the impact is large, both the raw material is electricity. Thing that could raise the cost of production, and increase competition especially ahead of the AEC, the competition would guess - a guess, If baseball is ready to face the plastics industry, will be lost, "he said.

In conclusion, Budi said, the plastic industry in the country is highly prospective, driven by the development of food and beverage industry, as well as in agriculture such as fertilizers plastic, plastic-harvest, post-harvest.

"In Java farmland narrowed but productivity rose 50 percent. Industry us it was nice, because it was in the international exhibition Indoplas plastics industry, Indopack, and Indoprocess and Indoprint 2014, the plastics industry will take advantage of the search engine exhibition - Hi Speed ​​machine," he said .

Plastic consumption figure of 2.5 million tonnes per year while demand 4 million tons. The rest of 1.5 million tons are imported. If this year does not go up 7 percent, then the domestic production will not increase, the greater import.

Managing Director of Messe Dusseldorf Asia, Gerno Ringling said Indonesia has a great potential in the plastics industry, packaging and printing and increasingly transformed into a very interesting market in the Southeast Asian region. With a population reaching 242 million people, Indonesia is predicted as the seventh largest market in the world by 2030 with 135 million consumers.

"Behind the success of this exhibition, we are sure Indoplas, Indopack, and Indoprint 2014 will experience growth not only in terms of area fairs as we continue to meet the needs of the market, but in terms of the number of visitors we are targeting 25 thousand visitors on 3 September to 6 September 2014," he said.

Aluminum for Moulding Plastic

The Plastic and rubber Industry is  constantly looking for alternatifve methods.

Processes and material to maintain economical production levels. Considerable interest is being shown in possibility of reducing the cost resulting from tooling as well as in The benefical use of row material properties.

Using The technology derived from air craft, space laboratory and armored vehicle field, the aluminum industri has developed a wrought aluminum plate spicifically designed for plastic and rubber moulding tool.

This plate has been use with Great succes in continental Europa, especially in Germany, and Italy, also Usa.

The alloy has a carefully controlled composition in AlZnMgCu type range and is manufactured under strigent condition.

This alloy is New but now is available to plastic and rubber industri.

General Aluminum Alloy Characteristics

Wrought / Cast Differences

Wrought plate results from hot rolling a cast slab that, after streching and various heat treatments, becames a homogeneous, stres relieved product with a 600 % improvement in properly levels over The cast original. It is produced to good flatness standarts, is from porossity and contains no inclutions or casting defects.

Machinability

The cutting speeds for machining of aluminum are considerably higher than for steel, and tool edges are subject to less wear. Over a period of time It is possible to improve output ; ptoduction times are shoter and better utilazation of machine tools that have been installed relatively. Esier and faster tool change is possible, and from practical observations It can be Said that the.

Copper-berillium can also be coated by merana of thermal spraying. For this purpose copper and aluminum bronze are primarily available as hardeners.

Function Moulds Venting

When the cavity space injected by plastic material, automatically empty space on the cavity will be filled with plastic material, the air in the cavity will be shifted to another place, what would happen if the air can not move, the air  will experience a high pressure , so the temperature rises even higher, resulting in plastic that fills the cavity will be burning, the defect is called a burn, because of the importance of venting a lot of products that fail due to not properly inject the gas vent, especially for products that have a rib that thin and tall, as compared to thick products. 

The function of the venting is Compressed  air release when compressed air is not expelled from the cavity, the plastic flow is inhibited, the result will be formed on a short shot of the product. Compressed  air will produce a gas with high temperature and burn the plastic around it, resulting in a defect burn marks, the product looks like a burn, this will greatly affect the look of the product. When  the gas mixed with plastic, the plastic will generate an uneven structure, which will reduce the strength of the product / mold parts produced, stress concentration also common in this region, which occurs due to the plastic notch.
part of venting, can divide on 2 section, land and groove, land is always contact with plastic melt, it's deep about 0.01 mm until 0.02 mm, depend on viscosity of material, relief of vent or gas land is about 1 mm until 2mm, but you must remember for rubber all the number above can't applied, gas vent on rubber material is very special, because rubber has low viscosity.
when designing the gas vent / venting on injection mould, make sure that all of the groove must have exhaust groove that connect to atsmosfer.
In modern plumbing, a drain-waste-vent  is part of a system that removes sewage and grey water from a building and regulates air pressure in the waste-system pipes, facilitating flow.  Waste is produced at fixtures such as toilets, sinks and showers, and exits the fixtures through a trap, a dipped section of pipe that always contains water.  All fixtures must contain traps to prevent sewer gases from leaking into the house.  Through traps, all fixtures are connected to waste lines, which in turn take the waste to a soil stack, or soil vent pipe.  At the building drain system's lowest point, the drain-waste vent is attached, and rises (usually inside a wall) to and out of the roof. Waste is removed from the building through the building drain and taken to a sewage line, which leads to a septic system or a public sewer. Cesspits are generally prohibited in developed areas.

Designing the Runner System in Plastics Mould

first-time we must consider items that affecting  runner size, some of whichVolume of part, the greater the volume takes a larger diameter runners anyway.Weight of part, the heavier parts, it takes a larger diameter runners. Wall thickness, the thicker the greater the diameter of the runner is needed.Length of flow path, the longer it takes the flow of large diameter runner.

Diameter

to determine the diameter, based on the type of material and wall thickness, the following chart can help, for similar materials PP, PA, POM, PC, PE can use the following graph, first select the appropriate thick wall thickness and look heavy parts, and then pull the line down, the approximate diameter required will be obtained.

INDUSTRIAL TRANSFORMATION

With the development of a business, you should start to see the possibilities for strengthening the possibility that has been achieved. 

Even this situation needs to better handling and the need to use appropriate methods to policy management policies.The one that looks real is more concerned with the principles of dynamic efficiency.

 As we know that the cost of the costs for the production process is very high, therefore the effective and efficient measures should be involved in the handling.Within the company as it headed toward the development or already developed ones, need to implement specialization emphasizes the importance of each sector of a global business process. 

This concept to be oriented, that growing either forward or the economy is still growing, can only be maintained if less exploit natural resources intensively and even tend to be large scale. In the production cycle of a multiple folding occurs very rapidly and is the mass of the types of consumer goods. Unlike the manufacture economic activity based on the information industry, seen as less dependent on natural resource extraction process directly. Besides, expansion of this sector requires social and environmental cost is relatively low when compared with the expansion of industrial manufacture.

 After a decade of ongoing forms of industrial society, a new society that is the information currently in the process. Riel tender can be seen in the fact that almost every aspect of modern society can not be separated from the information or at least touched by industrial product information that tends increasingly demand.                                                                                             

 Not only in the consumption of modern society, but further information including the sub-sector business support products to be one of the dominant production base in the structure of global economic growth. Economic slow activity distorsed to provision of information services available in the form of basic materials and even the interpretation of events with the community imagine.

 Different manufacturing industry that has been shown to cause pollution or chemical contamination of the environment, expansion of industrial activity information takes place with the environmental costs of such minimal. If on the other hand there is something fundamental to the argument that the industry more environmentally friendly than manufacturing industry, service sector in modern economies increasingly dominant information but there is a tendency, that the volume and variety of consumption goods will rise relative manufacture . We too believe that the information has been changed and transformed as a commodity product that is very broad.

Mold- Dies and Casting

The contuining development of dies mold tecnology demands more and more of processor.the most important problem in the process of dies molding is undoubtedly the corrrect design of the mold dies because the mold dies shop has little influence,if any.on construction of machine.
Efficient production of the most diverse molded parts depends primarily on the mold dies.

Durability of the mold dies depends on their core and treatment.Since ground,they should produce between 500.000-1000.000 shot.

For ease of contruction and the lower manufacturing cost.mold dies are becoming standarized.some forms offer ready made base of square or round design as standart of stripper plate mold dies for immediate use.
Only the insert then have to be fitted into the base.
