Important Tips For Your Plastic Machining Project

To find any machine shop is very easy. The difficult part is finding the shop that specializes in plastic machining, particularly plastic precision machining and other non-metallic parts and plastic machine parts.

Aerospace, fluid handling, medical and semiconductor are just few of the many industries that have constant demand for tasks that involve plastic materials and processes. Shops may be flooding the streets of America, however, finding the right shop that provides excellence service to customers on top of offering the highest quality of plastic precision machining service and plastic-precisioned products and parts. Building trust is essential. Sometimes it is easy, however at most, people place trust to wrong shops. To help you on this, there are several tips that serve as your guide, in case need for plastic machining arises.

Before purchasing plastic materials and machines such as plastic rod, plastic molds, plastic welding, plastic sheet, plastic injection molders, plastic fabrication and other plastic precision machining parts, you need to understand the capacity, condition and capability of the plastic machine or plastic machine parts. A conversation with the store manager or sales agent can be helpful.

Second, make sure that the plastic machine shop can give you important documents such as maintenance records, manuals and the complete manufacturer’s specifications and equipment retrofit quotes. These papers are great source of information that is useful in your decision making with regards plastic machining. Third, use the expertise of third party to verify the condition of the plastic machine parts. Their opinion or appraisal on the condition, quality and capability of the plastic precision machining parts and plastic materials are decisive. Today, there are several advantages of using plastic materials over metal parts.

Plastic materials have properties and characteristics that contribute to the high quality of the finished products at reasonable costs. These properties include lightweight, high-impact resistance, corrosion resistance, easy processing, high-wear resistance and less roughness. Experts suggest that beside great savings, plastic materials increase productivity, improved appearance and long duration without the lubrication requirements. Polyethylene machining parts are also preferred due to their being recyclable and environment-friendly.

When it comes to aeronautics and aerospace technology, plastic machining is preferred over materials because the former can withstand heat. Nowadays, plastic materials and plastic machine parts are used in solid fuel booster and ablative shields to allow re-entry of space shuttles.

In manufacturing helicopters, plastic materials and plastic precision machining play a key role for its durability, flexibility and capacity to absorb vibrations. Its being strong means the weight of the aircraft can be reduced without compromising quality and safety.

During World War II, plastic was first introduced as a substitute for rubber machining and items such as fuel-tank linings, flier’s boots and so forth. Today, plastic industry continues to evolve with technology. If your needs fall under the category of pipe systems, plastic machining is very helpful in few ways. First, it is cost-efficient as far as installation and equipment are concerned. Second, plastic precision machining and plastic materials require less maintenance. Third, they last longer than the metal counterparts.

Plastic machining including all plastic materials and plastic parts does not decompose. In fact, this property is advantageous because it allow engineers and manufacturers to recycle the plastic parts and materials. Its source is oil. However, scientists today are doing their best efforts to produce plastic from vegetable oil.

Custom Injection Moliding and the Lean Manufacturing Process

Custom injection molding has always been a fast moving, chaotic, and challenging business. It also has a high potential for profit, even today, despite the international competition and tight margins. You want to succeed, you see the possibilities, but the global pricing and high expenses make it very difficult.

Plastic injection molders are in the almost ideal business to benefit from the lean manufacturing process. If you embrace the entire concept and do not cherry pick the parts that are quick and easy, you will most certainly experience improvements in your operation.

The lean manufacturing process is an integrated approach to reducing waste. It could be time or material or anything else; waste is waste and waste equals money in business. It requires a shift in thinking to approach efficiency from this vantage point, rather than always striving to do more, do it faster, do it better.

Six Sigma

Implementing six sigma requires that management is dedicated to making it work in the long run. Employees are often cynical toward new programs because, in the past, many programs amounted to little more than slogans and banners.

Using a six sigma consulting firm is a good idea, once you have educated yourself in the basic principles. The time and expense of hiring an outside consultant will pay off handsomely over time. If you have the personnel to mange your six sigma implementation in-house that is even better; though they will certainly need some additional training.

5S

5S training will give you a huge boost in your lean manufacturing process. This is because the results are so immediate and visible. Everyone likes having the tools they need, the materials in the proper place with labels, and a general atmosphere of everything in it’s place.

It is relatively easy to get your employees to go along with a 5S program. Within a week you will see changes in your production area and the attitude of everyone. Find the key people, train them, give them the authority and communicate with the entire workforce in order to avoid grumbling and confusion.

Kaizen

When you conduct a kaizen blitz, or event, you pick an area or a process and focus exclusively on it. This is a great way to make progress and get people involved because it is by nature short and intense. It is a bit like cleaning up you kitchen before your mother-in-law comes for a visit! You hyper-focus on one area after another until the whole is done.

One drawback though with a kaizen blitz is that it can be mistakenly understood to be the entire process. It is just a component and it should be regarded as such. If it becomes the program, you will not really change the culture or become much more efficient in your operation.

How to get going

It is a good idea to talk to successful shop owners who have benefited from the lean manufacturing process. You will find them enthusiastic and quite willing to open up, for the most part. You should also read and gather information so you can make wise decisions rather than totally rely on the opinion of a consultant. In the end, you will certainly need outside help, but you also need a thorough understanding of the process yourself.

What Is Injection Plastic Mould And How Does It Work?

Injection plastic mould is a way of creating multiple parts that are the same shape. For example, if you have a manufacturing company and you need to create a large volume of plastic parts that are the same shape and size, then you would use plastic injection plastic mould machines to speed up your production line. The great thing about it is that it’s cost effective and it also requires little supervision from staff.

Injection rapid prototype works in a few stages. Firstly, the plastic is melted and pushed into a rapid prototype. The mould is then squeezed together to form the shape of the piece required. Next the machine will cool the mould (usually using water) and you are then left with a perfectly formed piece of plastic ready for the next stage in your production line.

Most of the time, people use injection plastic mould to make things faster and to make sure that things are very accurate. The machines that are used are all computerised and this means that they run like clockwork and are very accurate. They are ideal for creating the same product over and over again in a hurry.

Car manufacturers use these machines a lot – so for example, the lid of a radiator bottle in a car will be created using this. There are hundreds of cars made every year and therefore this sort of process is required to ensure speed and accuracy.

Hand making plastic products like this would be a real nightmare and although sometimes this is required, injection plastic mold is simply used when speed is of the essence. It’s also very cost effective because the only costs are the initial purchase, the plastic mold and of course water to cool the moulds when needed.

This makes it a very popular option for businesses who need to make things like this. Most major manufacturers use this service and there are a lot of options available on today’s market. You should have no problems finding something that’s suitable for your needs.

Making Plastic – Plastic Moulding

Ever wondered how plastic is moulded into the exceptionally useful things that we employ in our daily life? Is it as simple as melting plastic and lathering the sides of a mould with it and cooling it, much like chocolate? The answer, actually, is no. Moulding plastic is a little more complex than that. Plastic is made using a process often called plastic injection moulding.

What is this type of moulding

Plastic injection moulding is the method of manufacturing parts made of thermoplastic and thermosetting plastic by melting and forcing into moulds where they cool to form the desired object.
How does plastic injection moulding work?

The process of plastic injection moulding usually begins with an industrial designer or engineer who designs a product. This is followed up by the work of a toolmaker or mould maker who makes the mould to fit the design created. These moulds are metallic and usually made using either steel or aluminum.

Using machines, they are made to acquire the exact shape desired by the design. Once this is done, the process of actually making the plastic follows. This involves thermoplastic and thermosetting plastic being fed into a heated barrel and mixed. This melted material is then forced into the cavity of a mould and there it cools and hardens to form the desired part.

Some characteristics of the process:

1. I uses melted and mixed thermoplastic or thermoset plastic as the base
2. It uses a plunger which acts like a screw or a ram to force the melted material in the mould
3. It makes a shape that is open-ended and has taken the shape of the cavity of the mould
4. It shows a parting line and gate marks on the finished products and the ejector pin marks can also usually be made out

Some history

Alexander Parkes invented plastic in 1851 in Britain. This was worked on and bettered by John Hyatt, an American inventor in 1868. He also patented, in 1872, the first injection moulding machine. In the 1940s, the need for mass production of plastic products increased and saw the invention of the first screw injection machine by inventor James Hendry of America. This increased not only the speed of production but also the amount of precise control that could be exercised on the finish of the product.

Since then, this type of moulding has been used widely in the production of everything right from milk cartons to entire car panels and automotive parts. Since it is not a very costly material, it is best suited for mass produced goods.

Advantages of this type of moulding:

1. The rate of production are very high and therefore mass production is much benefitted
2. Since tolerance levels are high, they can be repeated
3. The labour cost is very low
4. The losses in scrap are very minimal
5. The products require very minimal finishing
6. A wide range of materials can be used

Disadvantages using this type of moulding:

1. Although labor expense and scrap loses are minimal, the cost of equipment and therefore investment is high
2. The running costs have the potential to be high
3. There is also need to design the correct parts

Plastic Moulding Innovation for The Smaller Company

Everywhere you look in the world you can see and feel plastic. Its pivotal to our lives – it is hard to imagine life without plastic fantastic.  No wonder plastic mouldings is a massive global business.

Approximately 30% of all plastic materials are manufactured by injection moulders. A very large proportion of this percentage is made through custom injection moulders technologies.  The process of custom injection moulding is quite complicated to the uninitiated and requires a large amount of specialised machinery to make it happen.  That is before the consideration of the selection of the raw materials which must be chosen for its quality and elasticy that depends on the end product being developed.

Given the wide-spread utilisation of plastic, there are many smaller companies that could benefit massively from plastic injection moulders as a way to produce parts. Given that the equipment needed is expensive,  the overheads for developing new products is preventing companies from innovating.

Thankfully, for these smaller companies, there are organisations that specialise in custom plastic injection moulders. They will make a mock up mould to the exact specifications, run it through the complete process and present the completed product to the customer for analysis.

One such company serving the UK is Iota Sigma. If you are looking at developing cost effective plastic mouldings through the utilisation of injection moulders then Iota Sigma, a Wales based Plastic Mouldings manufacturer, can provide friendly and constructive advice.  They can help develop products from the very first sketch through to custom rapid prototyping making a new concept for the enterprising company a low-cost reality.

Iota’s Sigma’s involvement early on in the development of a project can be a distinct advantage to the final finished product.  They claim their professional approach in ensuring customer quality, materials, process to meet specific goals and their plastic mouldings knowledge utilising Injection Moulders are second to none.  They are fully quality-driven and covered in the scope of their ISO9000 quality accreditation.
