1. Injection Molding
In Injection Molding, melted plastic is forced into a mold cavity. Once cooled, the mold can be removed. This plastic molding process is commonly used in mass-production or prototyping of a product. Injection molding machines were made in the 1930s. These can be used to mass produce toys, kitchen utensils, bottle caps, and cell phone stands to name a few.
2. Blow Molding
Blow molding is like injection molding except that hot liquid plastic pours out of a barrel vertically in a molten tube. The mold closes on it and forces it outward to conform to the inside shape of the mold. When it is cooled, the hollow part is formed. Examples of blow molding products are bottles, tubes and containers.
Equipments needed in setting-up a blow molding business are relatively higher than injection molding.
3. Compression Molding
In this type of plastic molding, a slug of hard plastic is pressed between two heated mold halves. Compression molding usually uses vertical presses instead of the horizontal presses used for injection and blow molding. The parts formed are then air-cooled. Prices of equipments used for compression molding are moderate.
4. Film Insert Molding
This plastic molding technique imbeds an image beneath the surface of a molded part. A material like film or fabric is inserted into a mold. Plastic is then injected.
5. Gas Assist Molding
Also called gas injection molding is used to create plastic parts with hollow interiors. Partial shot of plastic is then followed by high-pressure gas to fill the mold cavity with plastic.
6. Rotational Molding
Hollow molds packed with powdered plastic are secured to pipe-like spokes that extend from a central hub. The molds rotate on separate axes at once. The hub swings the whole mold to a closed furnace room causing the powder to melt and stick to the insides of the tools. As the molds turn slowly, the tools move into a cooling room. Here, sprayed water causes the plastic to harden into a hollow part. In this type of plastic molding, tooling costs are low and piece prices are high. Cycle time takes about 40-45 minutes.
7. Structural Foam Molding
Structural foam molding is a process of plastic molding usually used for parts that require thicker walls than standard injection molding. Inserting a small amount of nitrogen or chemical blow agent into the plastic material makes the walls thicker. Foaming happens as the melted plastic material enters the mold cavity. A thin plastic skin forms and solidifies in the mold wall. This type of plastic molding can be used with any thermoplastic that can be injection molded.
8. Thermoforming
In this plastic molding process, sheets of pre-extruded rigid plastics are horizontally heated and sucked down into hollow one-piece tools. When the hot plastic solidifies, its shape conforms to that of the mold.
Tooling costs are usually low and piece prices vary on the machinery.
Plastic molding is a very technical process. It needs experts in this type of manufacturing business for it to be competitive in the market. Therefore, a very scientific and systematic study should be first made before going into this endeavor.
EVAPORATION CONTROL / PREVENTION ABOVE SURFACE OF WATER
HOW DOES HOLLOW BALLS HELP TO PREVENTS EVAPORATION
PROBLEM
Heap Leach pregnant solution ponds need to be covered to prevent waterfowl fatalities. The conventional solution has been netting, which is expensive to maintain, is regularly damaged by winter storms and fails to camouflage the liquid surface from the air.
SOLUTION
By floating a layer of Ball on the surface, the liquid is camouflaged and birds fail to see the ponds. The balls rise and fall with changing liquid levels and easily accommodate objects such as floating pump barges.
LIQUID LOSS THROUGH EVAPORATION
Water is an expensive commodity, especially to mine operators who work in mountainous or inaccessible locations. A single layer of Balls automatically arrange themselves into a close packed formation over 80-91% of the surface area, greatly reducing sunlight penetration and therefore liquid evaporation. The thermal insulating qualities of Bird Balls also assist in maintaining winter operating temperatures of the water.
OPERATIONS
Balls are manufactured in black UV stabilised HDPE and should provide over 10 years of continuous service in conventional applications. The balls are also completely reusable, should another basin require covering when the original location becomes uneconomic.
MAINTENANCE FREE
Unlike netting, Balls are an install and forget solution. The balls are simply poured from their packing onto the liquid surface. Moderate winds and snow, which damage netting so easily, fail to affect a Ball floating cover.
SURFACE COVERAGE
The ball weight and diameter of the standard Balls usually gives optimum performance at moderate wind speeds whilst ensuring the most economical cost per square foot. A Ball weighs a nominal 30.0g and is 90-100mm(4") in diameter.
High Density Polyethylene (HDPE)- Suitable for working conditions up to 80C (176F). HDPE is recommended for all external applications due to its enhanced resistance to freezing conditions. Black, Ultra Violet stabilising additives prevent the degrading effects of sunlight. HDPE is also recommended for demineralised water and Chromic acid applications.
Polypropylene is liable to chain degradation from exposure to heat and UV radiation such as that present in sunlight. So HDPE is recommended in external application.
