ABS Injection Moulding And The Properties Of ABS

First off you may be thinking what is

ABS is (Acrylonitrile Butadiene) is a common thermoplastic used to make rigid, light, moulded products such as:

Golf club heads (ABS is used as it gives good shock absorbance). Piping (like Plastic Pressure Pipe Systems). Musical Instruments (mainly plastic clarinets and recorders being the most common). Toys (famously Lego Bricks). Automotive Body Parts Protective Head Gear Wheel Covers

A strange one you would not think of is ABS Plastic Ground to a diameter of less than 1 micrometer is commonly used in the inks for tattooists, it acts as a colorant and tattoo inks that do use ABS are extremely vivid.

Properties of ABS

The advantages of ABS are that being derived from Acrylonitrile, Butadiene and Styrene it combines the rigidity and strength of the Acrylonitrile and Styrene Polymers along with the toughness of the Polybutadiene Rubber. The most important properties of ABS are the toughness of the material and the resistance.

If during manufacture you increase the proportions of Polybutadiene in relation to Acrylonitrile and Styrene the impact resistance of the material will be amplified however this does cause changes in the properties.

Now you know about ABS onto the Injection Moulding Side of things.

ABS Injection Moulding

Thermoplastics and Thermosetting Plastics materials are the materials used in the process of Injection Moulding. ABS is a very popular choice of material due to its properties of strength, durability and rigidness. The ABS is fed into a heated barrel where it is mixed up and forced into a mould cavity, here it cools down and hardens to the properties of the mould cavity.

The moulds used are made by a mouldmaker or a toolmaker, they are based on the designs or an industrial designer or at times an engineer. The moulds are precision machined and made from metal, usually aluminium or steel.

The Characteristics of Injection Moulding

Produces on open ended or solid shape which conforms to the properties of the mould in place. Used Thermoset or Thermoplastic Materials (ABS being a material that can be used) Produces gate marks, a parting line and sprue. A screw type or ram plunger is used to force the molten plastic into the desired mould. Usually present on the completed product are ejector pin marks.

Injection moulding is used to manufacture many common products you will use everyday. Some of these products include:

Bottle Caps Milk Cartons Pocket Combs Containers Automotive Dashboards And most other plastic products that are available in the market today.

It is an ideal method if you wish to produce the same product in high volumes, the high production rate of injection moulding, low labour costs, high tolerances, wide range of materials that can be used, little need to finish the product after completion and minimal scrap losses are the main advantages of Injection Moulding.

8 Ways to Design Injection Moulding Parts with Consideration for Process

To ensure a successful finished product, you need to be aware of the process that goes into making your component. This should be at the forefront of your mind when considering the design of your part. Injection moulding will provide you with the component you want, and if you are able to consider its process in your design concepts you can guarantee a successful finished product.

Coherence. Try to make your design uniform throughout. That is, wall thickness, rib thickness and corner radii, for instance, should all be the same values. This will help the part to cool uniformly.
Wall thickness. Keeping your walls thin will ensure a faster cooling rate and less materials used. Lower cooling rate and less materials used will result in a shorter cycle time, allowing you more parts in a shorter amount of time, for less production cost.
To strengthen parts, ribs are more effective than thicker walls. Adding ribs at right angles to a wall will add considerably to its overall strength. It is a common mistake to thicken the walls of a design to achieve this effect when ribs are a cheaper and more effective option.
Ribs should be about half the main wall thickness.There can be some leniency here, but not too much or the ribs will be completely ineffective. Half is the generally accepted standard and is more than enough to increase a wall’s strength.
Corners and edges should be rounded wherever possible. Sharp edges do not always come out perfectly when the part is ejected from the mould.
Add a slight angle to the sides of your mold to allow easy release. A one or two degree angle should be applied to the mould on the face perpendicular to the parting line. This will allow for easy removal of the part from the mould.
Avoid undercuts. Protrusions on the part that will snag on the mould core or cavity when it is opened can make it impossible to remove from the mould.
Where possible, use lighter colours for your moulds. The mould is already cool when the molten material is being injected. As such it begins the setting process immediately and will sometime leave setting patterns. Using lighter colours will help y.to hide these patterns.

Injection moulding is the industry standard for creating lasting, quality parts. To be able to take advantage of this technology your design must meet its minimum requirements. Small considerations are all it takes and the result is a successful product that will meet all of your quality needs.

3 Main Cost Drivers in Injection Moulding

Injection moulding is an efficient and effective way of producing quality plastic goods. Quality is often assured, but as with any production process, there are factors to consider when cost is an issue. It is usually the cheapest way of manufacturing a product, but that doesn’t mean it won’t necessarily be expensive.

The cost of injection moulding may in part be dependant on the quality of the materials used, size and intricacy of the part, but here’s a rundown of the three biggest cost drivers when it comes to injection moulding.

Part design. A good part design will save a lot of money. When designing a part to be injection moulded, may things must be taken into consideration. For maximum efficiency, a part will be designed with consideration for materials, cooling time and the labour needed to create the tool. Bad part design will cost a lot of time and wasted effort. A badly designed part will cause rejects, slower cycle times (including cooling time) and extra labour. The part may not be designed well for tooling — especially if a part is complicated or intricate — and may require extra or special tooling costs. A part may be designed so that it still requires post-moulding work, adding yet more labour. This is not taking into account transport and packing costs; a good design will account for space requirements when in storage and shipment. Good part design reduces the costs of plastic moulding dramatically.
Tooling. The quality of the mould creation will alter the cost of injection moulding to a large extent. A mould’s design limitation is the parting line — the line which divides the two halves of the mould, the core and the cavity. This must be carefully considered when tooling a mould. For instance, a protruding portion of the mould, if the mould is correctly tooled, can be orientated along the parting line. If the mould is incorrectly tooled, however, this will create an undercut or overcut, and the part will snag in the mould. This will require labour to fix and will cost precious time that could be being used to create more parts.
Tool design. The quality of your tool design will impact immediately on both the quality and production cost of your finished part. Nothing accounts for quality, and the reliability of a tool that will deliver what you want every time will outstrip your initial investment in a very short amount of time. For instance, a cheaper injection moulding tool will only save you money in the short term. Long term, it’s lack of reliability and slow running time is likely to become a liability. Investing in a quality tool design specifically matching your needs and requirements will ensure you will have a consistently high-quality end product.

Taking time to consider your needs will bring you a worthwhile return on your investment. By insisting on good part design, tooling and tool design, you are assured a relatively stress-less endeavour when setting out to produce your product.

How Does an Injection Moulding Machine Work?

An injection moulding machine is a complex piece of machinery that creates one solid piece by injecting molten materials through a reciprocating screw system into a mould. This machine is made of many components; it is primarily consisted of a hopper, a barrel containing a reciprocating screw, temperature control devices, a clamping unit and the injection mould itself.

The process begins with the creation of a mould. The mould is created by the Toolmakers from the specifications given to them from the designer or engineer via a 3D computer-generated model. The mould is carefully constructed to allow the two halves of the mould — the mould cavity and the mould core — to separate along the parting line. This will allow easy ejection from the injection moulding machine when the part has cooled. If the mould is designed incorrectly the part may catch on the mould, resulting in possible damage.

The specifications and components of the machine must be carefully set up before the process of injection moulding can begin. Temperatures and pressures will be programmed according to the size and shape of the mould and the material that the part is to be made from. Once the machine is set, the cycle will begin and the machine can be left unattended to work its magic.

This is how it works:
Raw material and colour is fed into the barrel of the machine via the hopper. In the barrel the raw materials are subjected to pressure and temperature until they are melted and malleable. The reciprocating screw inside the barrel will turn, injecting a precise amount of the now molten plastic into the injection mould at a set and controlled temperature, pressure and speed. Once the mould is filled with the molten plastic the injection process will shut off. The part is then allowed to cool until it is ready to be taken from the mould. This can take some time depending on the materials, wall thickness, overall size and shape of the part being manufactured. When cool, the mould will open automatically. The mould is inbuilt with an ejecting mechanism which ejects the part in preparation for a new cycle. If a portion of the finished part is still caught in the mould at this point the mould will reopen until the part has been completely ejected. When the part is clear of the machine, the hopper will release more raw material and colour into the barrel and a new cycle will begin. The autonomous nature of the injection moulding machine means it can be left unattended once programmed, and may run continuously throughout day and night.

The basic concept of the plastic moulding machine has been around for over seventy years. Since then the original idea — injecting molten plastic into a mould — has evolved dramatically into an efficient, elegant and versatile tool for creating everyday items.

What Can Injection Moulding Do?

Injection moulding can do almost anything. This technology, created in the 1940s and constantly refined, allows for incredible flexibility in product design and has effectively revolutionised mass production.

Injection moulding is the process of forcing molten materials into a mould or die. The material is then cooled, the finished result taking on the physical characteristics of the mould’s cavity or hollow. Injection moulding is used for almost every plastic product that you will encounter on an everyday basis.Everything from the cap of your soft drink bottle to the dashboard of your car has been created through the injection moulding process. Even the plastic components that make up the computer that you’re using right now have been injection moulded.

There are a variety of materials that are compatible with injection moulding — from plastics to metals; almost anything that can be made malleable. The machine types vary in size, shape and running costs, allowing for a huge range of customisation. As with most items manufactured in mass quantities, plastic or metal products can be made in the same mould time and time again, meaning the cost of creating the mould is spread over the total number of items created. This allows items like coat hangers, toys and DVD cases to be produced for little more than the cost of the materials, whereas limited-run products, such as vinyl toys or custom-created art pieces will cost a lot more per unit.

You will find injection moulded products everywhere. The next time you buy a children’s meal from a fast food restaurant, you will likely find a toy comes with it. The cost of producing that toy will be very small as hundreds of thousands of the exact same toy have been created using the same plastic moulding shape (not to mention the cheaper materials). It may seem incongruous, but artists and designers take advantage of the same technology, using the process to create custom moulds. These one-off products will cost a lot more than the per-unit price of creating, say, one hundred from the same mould.

There are limitations to injection moulding. The nature of the process demands that only one whole, solid piece be created at one time. Designers and manufacturers get around this problem by altering their product design to these limitations. For instance, a toy plastic car will have two moulds for each half of the outside shell and perhaps another mould that will detail the inside, such as seats, dashboard and steering wheel. Injection moulding is so ingrained in our society that the limitations of injection moulding are not even considered limitations. If something cannot be created using injection moulding, there are very little options available, save carving the object by hand (a laborious task if you’re to create thousands of items exactly the same).

Injection moulding is versatile and a very necessary part of modern society. Able to create almost anything – functional or aesthetically pleasing – it broadens the horizons of tradesmen, artists, designers and everyday people. In short, injection moulding can create almost anything.
