Factors To Consider For Your Plastic Extrusion

At Rayda Plastics we have been extruding plastics since 1979, and are certainly experts when it comes to custom plastic extrusion. We work with a variety of clients from, Utilities and Construction, to food, farming and fishing. We are continually expanding.

It is important to us that the finished extruded product is the best it possibly can be and therefore, when discussing your custom plastic extrusion there are certain factors that will need to be considered in the design process in order to ensure that the finished plastic extruded profile is fit for purpose.  These factors will need to be considered in your design:

Wall Balance – So that the material can flow equally throughout, the wall thickness needs to be similar at all points. This will also allow the material to cool at a similar rate. If you had one area that had a greater thickness, its cooling period would be different causing the extrusion to bend. Continue reading

Plastic Is Fantastic – Rayda Reveal Common Plastic Uses

At Rayda we use a range of plastic materials to produce our plastic extrusions including; UPVC, Flexible PVC, ABS, HIPS, Polypropylene, TPU and more! Some are soft and malleable, others and hard and durable. We aren’t the only ones that recognise the fantastic benefits of plastic and it is therefore a favourable material choice within many different industries.

Medical industry – Plastic can help protect against contamination and therefore it often a popular material choice. Due to the shape that plastic can form plastic is also used to create tubes and other products needed within a medical environment.

Travel industry – You will find plastic material whether you are in your car or flying in a plane. The light weight properties that plastic possess,  means that it can help reduce fuel usage. Continue reading

UK Manufacturing And Its Benefits

At Rayda we have been manufacturing all of our plastic extrusions in our British Factory since we were founded in 1976. Being UK manufacturers ourselves we have always been hugely supportive of UK manufacturing and strongly believe that as a UK manufacturer we are able to offer some fantastic benefits to our extrusion customers.

We are able to deliver a personal, efficient and professional service tailored precisely to meet your needs from start to finish.

By using manufacturers in the UK there is often a reduced lead time, meaning your required product could be in your hands a lot sooner. As our extrusions are produced on site we can always provide you with accurate and ideal timescales.

Quality is extremely important to us at Rayda, we like to have complete control of the extrusion process so that we know exactly what is going on at all times. Continue reading

Plastic And The Automotive Industry – A Budding Relationship

At Rayda we like to know what else is going on within the Plastic Industry as a whole. One thing that has caught our interest lately is the role that the material plastic is playing within the automotive industry. There is much evidence to suggest that developments with using plastic within vehicles has improved some safety aspects. If this wasn’t enough there is also evidence to suggest that by using plastic, considerable energy savings are being made. As road users are always keen to spot the latest improvements in vehicles that could ultimately improve the performance of the car, the use of plastic is beginning to be noticed.

Most commonly, ABS (Acrylonite Butadiene Styrene),  HIPS (High Impact Polystyrene) and PP (Polypropylene) are the plastics that you can expect to find integrated into your vehicle in some format. From your air bags to insulation electrics, it would be near impossible to find a vehicle that does not contain plastic.

So why are we using plastic?

Plastic has many benefits and it seems that some of the following properties have made it a favourable choice of material for the automotive industry.

Cost Effective – plastic can be cheaper to produce than other materials commonly found in vehicles. Continue reading

Discussing Bio Plastics – Developments In The Plastic Industry

You will have noticed that within our blog we like to identify the positive developments that are taking place within the plastic industry and particularly those that will help protect our environment. Bio plastics are created from renewable biomass sources such as vegetable fats, sugar cane, starch or microbiota, straw or cotton. It is thought that by being able to produce plastics from these sources that the plastic industry will be able to move away from using limited fossil resources.

Some of the benefits of using bio plastic includes:

  • The components used to create bio plastics are more cost effective – cheaper than oil
  • Reduced carbon footprint during their production
  • The material can be recycled into other products again
  • Non toxic
  • Biodegrade much faster
  • Require less energy to produce
  • Less landfill area needed as they can be absorbed by the soil

Bio plastics are used in a majority of products such as food packaging yet can also be used to produce electrical housing.

Due to the benefits that bio plastics present it is thought that the bio plastics industry is growing at least 20% a year.

Types of Plastic Extrusion and Where to Use Them

There are so many different types of plastic that can be extruded, each with different properties and different uses. At Rayda Plastics, plastic extrusion involves extruding a wide range of materials and we have summarised each one below:

UPVC is a rigid form of PVC. It is both self-extinguishing and resistant to chemicals whilst being a low-cost material. It is ideal for indoor and outdoor use, which makes it great for window frames, drainpipes and fencing. It comes in a wide range of colours and grades so you’ll be able to find something for every situation.

PVC is a flexible material that comes in a range of colours and softness. Like UPVC, this material is low cost and can also be used both indoors and out. PVC is commonly used for gaskets, bumpers, sleeves and medical tubing.

The Use of Plastic in the Home

Why Plastic?

Plastic is a durable and strong material that uses fewer resources in production than a lot of its competitor materials. It is also often a lot more cost-effective than other materials, such as wood, metal and glass. The flexibility and versatility of plastic gives it plenty of uses in the home, both inside and out. It can be found on appliances such as televisions, telephones, and microwaves and in the textiles found on sofas, carpets and clothes.

It is also used heavily in kitchens and bathrooms due to its water and chemical resistant properties, which make it a hygienic material to use. Also, using plastic packaging for our foodstuffs can significantly extend their shelf lives.

 Which Materials are Used?

One of the most common plastics found in the home is Polyethylene Terephthalate (PET). This material varies between being rigid and completely flexible, which means it can be used in a number of circumstances. PET is water resistant and it is often used to produce packaging for foods and toiletries.  Continue reading

CEFLEX to Provide Solutions for Circular Economy

CEFLEX is a project where a number of European associations are working collaboratively to increase the relevance of flexible packaging, which is packaging produced from materials such as paper, plastic, film and aluminium foil. By doing so, they can generate solutions for a circular economy.

A circular economy is a continuous cycle that aims to give us as much use out of materials as possible. It follows the make, use, dispose cycle which can be constantly looped, provided there are adequate recycling opportunities available. Continue reading
