Spill containment of hazardous substances

Rotational Plastics NZ Ltd are leading manufacturers of rotationally moulded plastic products who have been assisting customers with design & manufacturing solutions for over 25 years.

If the storing or transporting of hazardous substances is part of your day to day activities, then you will have a need for spill pallets, spill containment berms, IBC spill pallets, drum pallets or other secondary containment solutions.

If you are dealing with chemicals, oils, sewage or the like then you will need to consider a form of Spill containment (or different forms of, depending on what you are dealing with) at your workplace.  Accidental spills or overflow, if contained within a spill containment unit let spills be contained within a barrier or drainage system rather than being absorbed at the surface.

Absorbent spill kits have been in place in workplaces for a number of years, but spill containment is considered now to be an eco-friendlier solution. This is mainly because absorbent spill kits have a small capacity, require disposal once used and allow no recycling of the spilled fluid.

Installing spill containment measures prior to a spill can result in significant savings in the event of a spill. Wise people count the cost of possible issues prior to them happening. Instead of paying for a costly clean up, containment measures reduce the impact on the environment and the surrounding area, and may even save some of the resource. Clean up costs can be impacted by numerous factors such as location of the spill, type of oil spilled, surrounding sensitive areas, and local regulations.

We manufacture industrial plastics

Do you have an idea for a new product? Need help making it happen?  We at Rotational Plastics can help. If you have an idea around plastic moulding that you want realised we can help you make it a reality from the design to the mould.  We can pretty much manufacture anything you can think of around industrial applications.  To make your ideas a reality we use the rotational moulding process.  This process is a low pressure, high temperature method to produce hollow one-piece plastic parts.  It is a competitive alternative to blow moulding, thermoforming and injection moulding.  This way your designs are produced stress-free and with near uniform wall thickness and moderately complex shapes.  For example, this is great for making canoes, toys, containers and such.  Rotational moulding is

  • Relatively simple and cheapindustrial_plastics
  • Possible to alter wall thickness without changing the mould
  • Complex parts with undercuts and intricate contours can be manufactured easily
  • Has very little waste
  • Is able to run short sizes, which is great for New Zealand

So come and talk to us as we can offer custom engineered solutions, high demand and production, mould generation and design, and commercial product supply in various verticals.  We take on any job no matter how big or small from one offs to whole ranges.  The plastic we use is called thermalplastics which means when your product is made it is high strength and stress resistant.  We make quality products so your ideas are in good hands with us.

 

Our company is New Zealand owned and operated and have been around for 25 years.  We have worked along with leading brands and cover a wide range of subjects from farming, to marine, to plumbing.  We believe in developing a strong customer relationship so we can best help you put your ideas into reality.  Your satisfaction is of high importance to us and it shows by our reputation of being reliable.  We can offer a free quote so call today and discus what we can do for you.

Is Plastic Molding Bad For The Environment?

Plastic has been a concern for a long time, with many claiming that it has very negative effects to the environment. However, plastic molding helps to keep waste levels down, keeping plastics out of landfills and disposal centers.

Firstly, why is plastic considered bad for the environment? Plastics take a long time to break down, which leads to quickly filling up landfills if it just dumped there after a short time being used. So making more plastic products would be bad wouldn’t it?

Not necessarily. Plastic molding is a very low waste process which reuses almost all waste products. Plastics can be remoulded into new products once they are used, keeping them out of landfills and making them useful once again. By recycling plastic products, plastic moulding actually helps the environment by keeping plastics in use rather than in the landfills.

How Does Plastic Moulding Work?

If you are having a custom plastic item made, you may very well be interested in how rotational plastic moulding works. It is actually a rather interesting process.

First, a mould is created of the item that is to be produced. These moulds are usually produced from CAD drawings, but it is possible to work from paper designs or physical models. Any metal items to be moulded are then fitted to the mould.

Polymer powder is then added to the mould and the mould is securely closed. The mould is slowly heated with hot air and rotated simultaneously. The movement of the rotation distributes the polymer evenly within the mould while it slowly begins to adhere to it. The moulded is then cooled, setting the polymer.

Now the mould is opened and the product removed from the mould, ready for any finishing and assembly. The moulding process is complete! Now the mould can be fitted with any new inserts and new powder put in ready for the next cycle.
