Here at Dienamics we feel very strongly about cutting down on plastic wastage. To ensure that we recycle as much plastic as possible each of our machines is equipped with sprue picker robots that pick out the wastage during the production and drops it into a granulator. These granulators regrind up the plastic into smaller granules and a vacuum system attached, sucks the regrind back into the moulding machine so it can be mixed back through the moulding run. We also, when possible, manufacture products in 100% recycled plastics. This helps to ensure a virtually waste free process and all of the plastic in our moulding department is used in final products rather than being sent to landfill.

Last week’s blog was all about Cold Runner Systems, this week, it’s time you learnt all about the alternate option – Hot Manifold Systems!

Also recycled plastic is more brittle than virgin plastic, so if your product needs structural integrity this needs to be looked at in the design process. It is certainly possible to design strong products using 100% recycled materials, however they need to be designed correctly with that strength in mind. Designing the product to have enough ribs among other features can open you up to more material options, including more recycled materials.

How does an Injection Moulding Press work? An Injection Moulding Press or Injection Moulding machine is a rather complicated, fully automated piece of machinery. An injection moulding machine makes moulded plastic parts quickly and with a high degree of repeatability. The plastic parts can be made from a range of different plastics for different purposes. […]

As your concept progresses through the design and development phases, it’s important to think about how you want your product to be manufactured.

Once your product has been designed, prototyped and you’ve ironed out any issues, it’s time to think about manufacturing. There are a few different techniques that could be used to manufacture your product. To decide which process is best for your product, think about: Market demand for your product Availability of resources The amount of […]

Injection moulding machines from 280 kN to 55,000 kN clamping force for all your requirements. Hydraulic, all-electric, hybrid, horizontal and vertical solutions of the highest quality.

Alternative plastics such as bio-PA, which are scratch-resistant, impact-resistant and abrasion-resistant, can fulfil different requirements for technical plastic parts.

It can be very difficult to get 100% recycled plastics in bright, vibrant colours due to the risk of contamination. Sometimes, designing a product that isn’t bound to a colourway can work in your favour. This can be quite effective and several people have come up with quirky designs that aren’t just restricted to injection moulding.

The basic concept behind rapid Tool Design for injection moulding has remained unchanged for the past 20 years. However, it is important to understand this basic concept to ensure success with injection moulding. This article will outline the four steps to success in rapid injection moulding product design.

An injection mould is the key to creating a successful one-piece finished plastic or metal component. Melted material is forced from the injection moulding machine into the mould (which is usually cool) where it sets. The result is a solid piece of the material which may be a component to, or the whole of, a […]

Plastic products are all around us in our daily lives. Have you ever wondered what it would be like to live without plastic products? The future of plastic manufacturing seems hazy, given all of the environmental concerns about plastic. Many people are trying to move away from traditional plastics in search of more sustainable alternatives. […]

When it comes to injection moulding, there are many factors you need to consider to make sure you are putting the tool in a suitable machine and tonnage is an important one!

A sad fact of injection moulding and plastics manufacturing in general, is that plastic shrinks. And sometimes it shrinks a lot. So as plastic Injection moulders we’ve learnt to deal with shrinkage and today we are going to share a few of our tips and tricks to avoid excessive shrinkage and explain a bit about […]

Plastic injection moulding is a booming industry. Almost every product in the 21st century requires plastic in one form or another. The invention of plastic was one of the greatest achievements in industrial production due to the fact that it’s synthetic and not limited in nature. Here are the eight most important types of plastic […]

PBAT, PCLAlternative plastics that are biodegradable but produced from fossil sources such as crude oil or natural gas are categorised as bioplastics. The injection moulded component degrades naturally in the environment.

PLA, PHA, PHBThese are bioplastics that are both biobased and biodegradable. Chemical processes enable the biodegradation of bioplastics. Microorganisms present in the environment convert the bioplastic into natural substances such as water or compost. The injection moulded component degrades naturally in the environment.

In the cases where using 100% recycled plastic is not ideal we can still use some percentage of recycled plastic. The general rule for mixing reground plastic into a moulding run is that 20% recycled plastic can be mixed in without impacting the strength of the end product. Product testing is always suggested when wanting to use recycled materials to ensure you are still getting the exact quality of product you require.
