Building materials made from recycled plastics are not yet widely used in the construction industry – prototypes have mainly been used for demonstrative installations. It will take political will and widespread environmental awareness to encourage more investment into the potential in plastics recycling.

Gifted with extraordinary technical know how and an authoritative yet plain English writing style, in this collection of articles Fattori offers his insights on a variety of molding-related topics that are bound to make your days on the production floor go a little bit better.

Additive technology creates air pockets in film during orientation, cutting down on the amount of resin needed while boosting opacity, mechanical properties and recyclability.

Such recycled plastics may have lower mechanical properties compared to virgin plastics, because each time you melt and process a plastic, the polymeric chains degrade. But these properties can be recovered by mixing it to additives or virgin plastic. Examples of successful industrial recycling include PET, or poly(ethylene therephtalate), which is used to make soft drinks bottles, and polystyrene.

SPT Vilecon, a development and manufacturing services provider in the medical device and pharmaceutical industries, has implemented a prototyping process that de-risks and accelerates the development process by going directly to a representative, injection molded part. Without creating a steel tool. The process is Nexa3D’s freeform injection molding technology (FIM), which uses additive manufacturing to create single-use, dissolvable injection molds.

The disposal of plastics is a highly visible global problem – from the highest mountains to the deepest ocean trenches, waste plastic seems inescapable. In natural conditions, plastics are nearly indestructible, and yet they are discarded worldwide on a large scale: the world produces around 359 million tonnes of plastics each year. The environment cannot address their disposal at a speed fast enough to prevent harm to living beings.

Say “manufacturing automation” and thoughts immediately go to the shop floor and specialized production equipment, robotics and material handling systems. But there is another realm of possible automation — the front office.

Ultradent's entry of its Umbrella cheek retractor took home the awards for Technical Sophistication and Achievement in Economics and Efficiency at PTXPO.

“xMOLD is unique in enabling us to manage complex part features with ease, as we can simply dissolve the mold elements that will normally require high-cost steel mold elements like sliders or collapsible cores,“ says Lasse Staal, director of freeform injection molding at Nexa3D.

Our team is currently trying to develop a viable building block made of recycled plastics. We have prepared a range of prospective materials using a mix of virgin and recycled plastics – coloured PET bottles, polypropylene, polyethylene – and other local waste-stream materials, such as hemp, sawdust, concrete waste and red mud.

In this collection of content, we provide expert advice on welding from some of the leading authorities in the field, with tips on such matters as controls, as well as insights on how to solve common problems in welding.

So perhaps plastics are not necessarily the problem. They can be part of a pathway towards a more sustainable way of living. Using a natural or renewable resource is not necessarily environmentally friendly. The ecological footprint of a polymeric material is smaller than that of natural materials, which have a sizeable demand on arable land, clean water, fertilisers and regeneration time.

But hopefully the tide is beginning to turn, as a consequence of the increasing pressure from public opinion about the plastic pollution matter. Thanks to the engagement of government and industry with the idea of a circular economy, it seems that there will be an opening in the market – and in people’s minds – to welcome plastic initiatives to replace conventional building materials.

The main issue is not with plastic as a material, but with our linear economic model: goods are produced, consumed, then disposed of. This model assumes endless economic growth and doesn’t consider the planet’s exhaustible resources.

This Knowledge Center provides an overview of the considerations needed to understand the purchase, operation, and maintenance of a process cooling system.

Many universities and entrepreneurs are attempting to do this. Most solutions target mixed plastic waste and suggest applications different from the original ones. For example, several groups have developed building materials made of plastic waste.

According to the Global Footprint Network, before the pandemic we were demanding 1.75 times the available resources of the planet. Working with the “unrecyclable” waste and developing plastics alternatives to natural materials may reduce this demand and leave a cleaner and more sustainable planet for the next generations.

At captive processor McConkey, a new generation of artificial intelligence models, highlighted by ChatGPT, is helping it wade through the shortage of skilled labor and keep its production lines churning out good parts.

I study plastic waste with the specific aim of finding interesting ways to remove it from the environment. Since 2009, I have developed a number of building materials made of post-consumer plastics mixed with different waste-stream materials. From agricultural wastes such as sugarcane bagasse – a by-product of the sugar industry in Brazil – and coffee dregs, to concrete waste and construction debris, compounded with recycled plastics, there are many ways to obtain materials to produce bricks, roof tiles, plastic lumber and other useful elements for building.

The Plastics Industry Association (PLASTICS) has released final figures for NPE2024: The Plastics Show (May 6-10; Orlando) that officially make it the largest ever NPE in several key metrics.

New designs of medical device components demand a higher level of testing and scrutiny due to the critical nature of their uses and the potential consequences of failure. In health care settings, a malfunctioning device can have life-threatening implications. Rigorous testing is essential to de-risk new designs by ensuring that components function safely and effectively. For this testing to provide meaningful results, the parts need to be representative of production parts. Investment in a steel production tool can be a risky decision point for a product developer, putting leaders in the position of committing to a design that may later need to be changed based on verification and validation test results.

When, how, what and why to automate — leading robotics suppliers and forward-thinking moldmakers will share their insights on automating manufacturing at collocated event.

The flexibility, biocompatibility and stability of silicone make it an essential material for medical device components. However, these components can be challenging to prototype. Thermoset materials such as silicone cannot be melted and built up the way a thermoplastic material can be. There are ways of printing silicone parts, but the results are not as precise and not comparable to injection molded parts. Precision is especially important for medical device assemblies, such as those made by SPT Vilecon.

The FIM process starts with a 3D printed mold, its design is the inverse of the desired part and printed from Nexa3D’s xMOLD resin. Once the mold has been printed and assembled, it is placed in a mold base in the injection molding machine. The mold base may be a simple metal plate or a more elaborate master unit die, depending on the application. Material is injected into the cavity to form the part, and the cavity and part are ejected from the mold base to cool. The tooling is compatible with standard injection molding machines, and no special modifications are required.

But there are many ways we could set plastics on a different lifecycle – and one that I have been working on is turning disused plastics into a hardy, reliable and sustainable building material.

Most people believe that plastics recycling is severely restricted: that only a few types can be recycled at all. This is unsurprising. The proportion of plastics that are recycled is minimal. The UK, for example, uses five million tonnes of plastic each year, and only 370,000 tonnes are recycled each year: that’s just 7%.

According to SPT Vilecon CEO Bjarne Andersen, FIM saves customers both time and money. By getting testing done faster and on prototypes made with the right materials, Vilecon can get a design to a “fast fail” or to market sooner — whichever the case may be — thus shortening the time before a product starts generating revenue.

In this collection, which is part one of a series representing some of John’s finest work, we present you with five articles that we think you will refer to time and again as you look to solve problems, cut cycle times and improve the quality of the parts you mold.

Across all process types, sustainability was a big theme at NPE2024. But there was plenty to see in automation and artificial intelligence as well.

After successfully introducing a combined conference for moldmakers and injection molders in 2022, Plastics Technology and MoldMaking Technology are once again joining forces for a tooling/molding two-for-one.

While prices moved up for three of the five commodity resins, there was potential for a flat trajectory for the rest of the third quarter.

The problem is that recycling much of this plastic waste is currently unfeasible and unprofitable. Polymers such as rubbers, elastomers, thermosets and mixed plastic waste are comfortably labelled as “unrecyclable” by the recycling sector. But the amount of these materials all over the world is frighteningly large and keeps on growing. What if this plastic waste could be used to produce something useful to society?

Despite price increase nominations going into second quarter, it appeared there was potential for generally flat pricing with the exception of a major downward correction for PP.

Successfully starting or restarting an injection molding machine is less about ticking boxes on a rote checklist and more about individually assessing each processing scenario and its unique variables.

The mold and part are then placed in Nexa3D’s xWASH-FIM device. In the washing chamber, the resin is dissolved in solvent, leaving the finished part behind. Besides getting to an injection molded part more quickly, the process also removes some geometric constraints on molding that can require additional tooling in other situations. Unlike a traditional mold, a dissolvable mold does not have to release the part after injection.

New system automatically cleans mold-cooling lines—including conformal channels—removing rust and calcium, among other deposits, while simultaneously testing for leaks, measuring flow rate and applying rust inhibitor.

This has led to a consensus that plastics are an unsustainable material. And yes, plastics are certainly an enormous problem, but they don’t necessarily have to be.

Plastics are strong, durable, waterproof, lightweight, easy to mould, and recyclable – all key properties for construction materials. So what if all of this plastic waste could be converted into building materials for low-income populations? Existing initiatives are promising, but not yet reproducible on an industrial scale.

We are currently adjusting the properties of the materials for the rotomoulding process, a plastics moulding technology that is ideal for making large hollow articles. We want to use the maximum amount of recycled plastics in this block. Blocks made of 25% recycled plastics have performed extremely well in mechanical tests. Next we’ll try 50%, 75% and 100%.

While prices moved up for three of the five commodity resins, there was potential for a flat trajectory for the rest of the third quarter.
