Plastic Injection Molding: Mold products absorbing Plasticizing, Injection, Chilling, Ejection  

Article by pitterpoul







Employing various techniques like thermoplastic and thermoset Injection Molding, blow molding, gyratory molding, compression molding, thermoforming, structural foam molding, etc

We offer comprehensive support from initial concept to final prototyping through production and finishing so that you get the best product and value for your money. Injection molding is widely used for manufacturing a variety of parts, ranging from the smallest accessory to entire body panels for industries like automotive, aerospace and agriculture. Plastic Injection Molding mainly involves following four steps:

•Plasticizing: During this process we convert the polymer material from its hard granular form to the liquid form at correct melting point. The pellets or plastic powder is melted with in the machine. Powdered or palletized materials used in Plastic Injection Molding machines mainly are, Ethylene, Polycarbonate, Nylon, Polypropylene, Acrylonitrile-Butadiene-Styrene (ABS) and Polystyrene.

•Injection: It is an important step during overall Plastic Injection Molding process when heated fluid is forced in to the mold at very high pressure. It is fed in to the mold through a nozzle by a long screw plunger inside a heated barrel.

•Chilling: It involves cooling the melted fluid to allow it go gain rigid shape.

•Ejection: Here, we remove the cooled and molded object from the mold cavity.

Plastic Injection Molding is widely used to manufacture automotive parts like levers, gears and switches, and medical equipment components like blood analyzer, hear pump parts, orthopedic devices, etc. Plastic Injection Molding is the reason behind a variety of plastic products we use in modern world. Be it your lawn chairs or the PC monitor you have in front of you etc. Plastic Injection is very important process in the manufacturing industry to cast and mold plastic in different shapes and sizes. Almost 32% of all plastics by weight is processed by injection molding. Through Plastic Injection Molding we pass melted plastic in to a mold cavity of inverse shape and allow it to cool resulting in the desired plastic form. We can produce geometrically complex plastic products through Plastic Injection Molding

Choose Your Plastic Products with Care

Filed under: Plastic Injection Molding — Tags: , , , — Rolf @ 3:13 am

People of a certain generation remember when a neighbor whispered a hot tip into the Graduate’s ear, “Plastics.” That was a reflection of the 1960′s excitement over the material that promised to revolutionize manufacturing, industry and household living.


To a large part, that prediction came true. It’s hard to imagine daily life without plastic. I type on my Think Pad made of light and durable plastic; plastic medical instruments, building materials, automobile parts, cell phones, toys and tools make things in America affordable, convenient and portable. A world without plastic is almost unimaginable.


Environmental Impacts

As the cost of oil rises, it’s perhaps time to take a closer look at how and why we use plastic products – and what impact the disposal of plastic items has on an environment we now recognize is in peril. It is difficult to measure how much of oil drilled and shipped to refineries is used in the production of plastic. One estimate is a low as 4 percent and energy experts doubt that, should demand for plastic diminish, there would be less drilling and production of oil.


Once crude oil and natural gas are shipped to refineries, they are separated into many categories of petrochemicals. Some of the ethane and propane are siphoned off for use in the making of plastic pellets – the raw material that’s sent to manufacturers of plastic products. It appears that a significant environmental impact of the plastics industry is in production, transportation and disposal of products. In these activities, the use of gas is significant.


Despite outreach efforts by the EPA and many environmental groups, the recycling of plastic bottles – particularly those made with polyethylene terephthalate (PET) – is abysmal. Up to 80 percent of PET beverage bottles end up in landfills where they take 1,000 years to degrade. The same is true of the over-abundant plastic wrapping used on many products – from small toys and cosmetics entombed in many square inches of plastic to electronics and larger items.


More Product, Less Package

The EPA is a strong proponent of packaging that minimizes the use of plastic. Some industries have responded. For example, CD’s and DVD’s once came encased in lots of plastic packaging. Now, the outer packaging has been eliminated or is removed and reused after a sale.


Unfortunately, as one industry seems to get the message, another does not. The popularity of bottled and flavored waters in PET containers has taken the world by storm. We already know the majority of these plastic bottles are left to degrade and pollute natural environments for millennia. But, even when people are conscientious recyclers, the energy needed to transport and transform plastic into new materials takes its own toll on the environment.


Governments and municipalities have done their best to educate people about the benefits of recycling plastic containers – and suggested using alternatives to plastic. These environmental concerns have not been heard by an industry that makes billions from pouring water into plastic bottles or encasing tiny products in massive plastic packaging.


It seems up to the consumer to send a message by making smart choices about which plastic products to purchase and use. People can start by developing new habits – such as purchasing a personal water bottle that’s made of lightweight metal. Lots of bottled water is actually no more than tap water, some treated, some not. Households can be equipped with a variety of water filters if the tap water is unpalatable. Water filters cost a fraction of bottled water and is under EPA quality control.


Plastic Benefits Abound

Clearly, plastic contributes greatly to the convenience and efficiency of daily life. For example, massive water storage tanks – above and below ground – are often made of durable plastic that serve their purpose for decades when other materials crack and rust. Our cars are made from a variety of molded plastic parts that make them lighter and more fuel efficient. Since 1988, the average passenger car has lost about 145 pounds, saving about 21 million barrels of oil. Plastic components help us explore outer space and examine the microscopic building blocks of life.


Our households are switched on by plastic. It’s insulating and thermal properties keep electrical systems in our homes safe. The plastic interior of our refrigerators cover plastic insulating foam that saves up to 30% of energy costs.


Consumer Purchasing Power

It’s clear that plastic is an essential building block of modern life. But, it’s up to consumers to use this manmade resource wisely. On one hand, plastic creates efficiency and savings and can help preserve our natural environment while on the other it can be an instrument of destruction. Thoughtful people will discern the difference and choose alternatives to beverages in plastic bottles and items with more plastic packaging than product. They’ll use plastic products that are durable and not designed to be discarded.


Granted, kicking the plastic throw-away habit probably won’t impact the price at the gas pump. But, it will send a message to product manufacturers that Americans can, through purchasing power, support positive change that benefits the planet’s future.

Medical Plastic Injection Moulding – Procedure and Products

Filed under: Plastic Injection Molding — Tags: , , , , — Rolf @ 3:10 am

In 1868, John Wesley Hyatt developed the first plastic injection mold, and the plastic injection moulding process. He used the plunger method to successfully inject hot, liquid celluloid, often called the first thermoplastic, into a split-die mold. This process was little changed until James Hendry built the first screw plastic injection mold in 1946. Today, nearly all industrial and medical plastic injection moulding processes use the screw method.

Plastic moulding is a very methodological and technical process. Thus it needs experts in this type of manufacturing business for it to meet the safety terms and to be competitive in the market. A very scientific and systematic mechanical study is first made before going into this endeavor. Here I have discussed some known plastic injection moulding process that can help you to understand the various ways it is done for industry specific plastic products.

1. Injection Moulding.

Examples of applications: Medical plastic laryngeal mask components, laboratory products, extraction systems, toys, aircraft undercarriage components, kitchen utensils, bottle caps, and cell phone stands.

In Injection Moulding, melted plastic is forced into a mold cavity. Once cooled, the mold can be removed. This plastic injection moulding process is commonly used in mass-production or prototyping of a product. Typically this process is used to produce plastic mouldings where the relatively high tooling cost can be justified by low unit costs and tolerances which cannot be achieved by other moulding processes.

2. Blow Moulding.

Examples of applications: Automotive, Toys, Recreational, tubes and containers, Medical, Housework Appliances

The process is divided into three steps: injection, blowing and ejection. Blow moulding is like plastic injection moulding 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. Equipments needed in setting-up a blow moulding business are relatively higher than injection moulding.

3. Compression Moulding.

Examples of applications:  Automotive exterior panels especially for commercial vehicles, Radio & appliance knobs, ash trays & electrical parts.

In this type of plastic moulding, a slug of hard plastic is pressed between two heated mold halves. Compression moulding usually uses vertical presses instead of the horizontal presses used for injection and blow moulding. The parts formed are then air-cooled. Prices of equipments used for compression moulding are moderate.

4. Film Insert Moulding.

Examples of applications: FIM can be used to apply clear scratch-resistant hard coats, logos, text and graphics in any color or combination of colors to plastic parts prior to injection molding.

This plastic moulding 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 Moulding

Examples of applications:  Flat panels for office equipment, Computer enclosures, Furniture, i.e. tabletops, Automotive panels, Domestic appliances – e.g. fridges.

Also called gas injection moulding 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 Moulding.

Examples of applications:  All kinds of plastics mostly hollow Plastic Parts.

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 moulding, tooling costs are low and piece prices are high. Cycle time takes about 40-45 minutes.

7. Structural Foam Moulding.

Examples of applications: Typical products are large trash containers, freeway sand safety containers and in-ground housing for water systems.

Structural foam moulding is a process of plastic injection moulding usually used for parts that require thicker walls than standard injection moulding. 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 moulding can be used with any thermoplastic that can be injection molded.

8. Thermoforming.

Examples of applications: Clamshells, Trays, Blisters, Displays, Guards, Covers, Totes, Shields, medical plastics

In this plastic moulding 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.

Rotational Molding – Seamless Manufacturing Method For Millions of Products

Filed under: plastics manufacturing — Tags: , , , , , , — Rolf @ 6:34 am

There are so many common products we take for granted in everyday life. While it’s true that many urban kids don’t know that milk comes from cows or what a real wheat field looks like, the same is true for manufactured products that are mainstream to life in America.

How about the garbage bin outside your home, the bright orange road cones used for road safety, bicycle helmets and giant tanks used for water storage? Chances are these disparate products were made using a popular manufacturing method called Rotational Molding. What they have in common is a hard, continuous outer shell and a hollow space inside.

The Process

Rotational molding was an innovation of the 1940s, but wasn’t widely used until the development of better technology that made the process faster. In addition, new polymer and plastic products entered the marketplace and were well suited for rotational molds. This method of molding plastics has several advantages over some other techniques which result in higher prices for products and a less environmentally friendly process.

The first step in producing a lightweight and affordable polyethylene (plastic) product is to create a mold. This is usually done using a computer software program capable of creating three dimensional images. The mold is most often made of aluminum because the lightweight material is easier to handle than some other metals although it may be a bit more costly. Machinists get to work tooling the mold from the design. Once the mold is done, the rest of the process is in the hands of the plastics manufacturer where the rotational molding is done.

Here’s where some imagination is required. Picture the ride at the State Fair where a person is strapped into a kind of gyroscope that turns them up, down, sideways and around. That’s what will happen to the mold. But first, the manufacturer measures polymer resin, a granular powder, and pours it into the mold. The mold is fitted into place in an oven that’s heated to an appropriate temperature. Inside the oven, the mold makes its axial turns, spreading the grains of polymer evenly over the inner surface of the mold.

As the aluminum quickly heats up, the resin melts and continues to coat the inside of the mold. The time the mold spends spinning and heating is critical to the quality of the product. In the past it was up to the rotational mold experts to judge when a mold was ready to remove from the oven and cool. Today, sensitive instruments gauge the air temperature in the mold, improving quality control.

Fans are often used to help the mold cool. Unlike some other mold methods – such as injection molds – the cooling of the aluminum causes the mold to shrink slightly away from the interior of the mold. This allows easy removal of the largest products, such as water tanks. The product is then carefully inspected by the rotational manufacturer and, if it meets all specifications, is shipped to the customer.

Molding Benefits

For many products, rotational molding makes a big difference in the price of a product and in its durability. The manufacturing process does not require lots of interlocking and moving parts. Therefore, maintenance is minimal as is replacement of parts. In addition, there’s little waste of material, a factor that makes the process more environmentally sound.

Durability of products is also very important to manufacturers, particularly those marketing items that will serve customers over extended periods of time. For example, a water tank produced with the rotational molding process will provide much longer service than a comparable steel tank. Rotational molds can be made to any specification or shape, and can be manufactured in less time than steel. They are also very lightweight, cost less to transport and are not as challenging or awkward to install onsite. Of course, a big advantage to molded tanks is that, unlike steel, they will never rust.

Next time you see a one-piece, hollow product made of polymer plastic (maybe a kayak or the face of a doll) astound your friends with the fact that you know just how it was done – with the rotational molding process.
