Our Plant And The Rotational Molding Process

The rotational molding process (also known as rotational moulding – depending on which side of the 49th parallel you are on) is remarkably simple, as most profound things are. Pigments and materials are mixed for consistent colour and added to a mold, or form. Before entering the oven the mold is inspected for ingredients and sealed. The mold enters the oven and the bi-axle rotation ensures consistent heat and product consistency. The mold is cooled, and the plastic part is removed. The rotational molding process results in short lead times, low tooling costs, and complex yet consistent part production.

We finish and trim plastic parts using our 5-axis CNC machine. Having a 5-axis CNC machine means it has the ability to trim complicated shapes without having to do multiple part setups as it has the ability to move on five different axes at the same time. This helps the cutting tool approach the part from all directions resulting in almost limitless applications possible. It also means the parts can be produced quickly and efficiently while maintaining accuracy. A process that can be endlessly repeated. A process that can accurately scale with the quality and manufacturing demands of your business. What does this mean for you? If it can be done, we can do it.

Having over 40 years experience means we have pretty much seen it all. No matter the material, size, timing needs or stringency of quality control; we do it all. Some parts need to be one-piece, others multiple pieces that fit together. Some need to be shipped in individual parts, others assembled. Some need to be simple, others very complex. Some even require complex design inclusions such as metal inserts, graphics, or even foam in the wall of the part. No matter what you need, our response is pretty much always the same: “absolutely, we can do that!”

Northwest Plastics is ISO 9001 Certified. What does that mean, and why should you care? ISO 9001 Certified means that we have met the requirements in ISO 9001 as it relates to our Quality Management System. In normal human terms, that means we strive for consistent results while we continually improve our process. It means our focus is 100% on customer satisfaction and meeting customer expectations. To be ISO 9001 Certified means that we must pay attention to our customers. It means our Quality Management System is appropriate and effective in meeting the exacting expectations of our demanding, yet happy clients.

Our process is profoundly simple; so what makes Northwest Plastics unique? What makes us stand out? Our ability to handle EPS foam processing is one of the things that does. We realized that there was a need to make large industrial floats. So we thought of an innovative way to make that happen! We custom designed, built, tested, and implemented a manufacturing technology, that has since become tried and tested. What does this mean for you? Simple: if we don’t already have a solution for your business challenges, we’ll build one!

Northwest Plastics is conveniently located on the Canada – US Border in British Columbia Canada. Every day however, we ship finished products all around the globe: this ranges from doing weekly deliveries to our OEM customers based in Western United States to shipping parts and products to South America, Asia and Europe. Another of the many reasons clients have stuck with us for decades is because we don’t nickel and dime them for things like the storage and maintenance of forms and tools. In fact, we’ve built our entire facility around ensuring we can continue doing so!
